+
+## Building the Source Distribution
+
+Apache Marmotta uses Maven to build, test, and install the software. A basic
+build requires downloading and installing Maven and then running:
+
+ mvn clean install
+
+This will compile, package and test all Apache Marmotta modules and install
+it in your local Maven repository. In case you want to build your own
+projects based on some of the libraries provided by Apache Marmotta, this
+usually suffices.
+
+The default loglevel for most unit and integration tests executed during the
+build is INFO. To change the loglevel for either more or less output, you
+can pass the loglevel as system property:
+
+ mvn clean install -Droot-level=TRACE|DEBUG|INFO|WARN|ERROR
+
+Note that some of the integration tests start up parts of the Marmotta
+platform during execution. The log level for these tests cannot be
+changed, as Marmotta is taking over the log configuration in these
+cases.
+
+## Building, Running and Deploying the Wep Application
+
+Apache Marmotta also includes a default configuration for building a Java
+Web Application that can be deployed in any Java Application Server. To
+build the web application, first run
+
+ mvn clean install
+
+in the project root. Then change to the launchers/marmotta-webapp directory
+and run
+
+ mvn package
+
+This will create a marmotta.war file in the target/ directory. You can
+deploy this archive to any Java Application Server by copying it into
+its deployment directory; [more details](http://marmotta.apache.org/installation.html).
+
+Alternatively, you can directly startup the Apache Marmotta Web Application
+from Maven with a default configuration suitable for development. To try this
+out, run
+
+ mvn tomcat7:run
+
+wait until the system is started up and point your browser to `http://localhost:8080`
+
+When developing it is sometimes useful to always start with a clean confi-
+guration of the system. Therefore, you can also start up the web application
+as follows:
+
+ mvn clean tomcat7:run -Pcleanall
+
+This command will remove any existing configuration directory before startup.
+
+## Building the Standalone Installer
+
+The build environment also offers to automatically build an installer package
+that guides users through the installation with an easy-to-use installation
+wizard. The installer is based on izPack and dynamically assembled when
+building the package. To build the installer, first run
+
+ mvn clean install
+
+in the project root. Then change to the launchers/marmotta-installer directory
+and run
+
+ mvn package -Pinstaller
+
+The build process will automatically create an appropriate installer confi-
+guration from the Maven dependencies through the Apache Marmotta refpack
+build plugin.
+
+The installer can then be tried out by running
+
+ java -jar target/marmotta-installer-x.x.x.jar
+
+
+## Building a Docker image
+
+Marmotta also comes with support for creating a Docker images that you can use for development
+or testing:
+
+1. Locate at the root of the source repository
+2. Build image: `docker build -t marmotta .`
+3. Run the container: `docker run -p 8080:8080 marmotta`
+4. Access Marmotta at [localhost:8080/marmotta](http://localhost:8080/marmotta) (IP address may
+ be different, see information bellow).
+
+An official images is [available from Docker Hub](https://hub.docker.com/r/apache/marmotta/) as
+an automated build, so you just need to pull it from there to replace the second step above:
+
+ docker pull apache/marmotta
+
+
+## Building with a Clean Repository
+
+Sometimes it is useful to check if the build runs properly on a clean local
+repository, i.e. simulate what happens if a user downloads the source and
+runs the build. This can be achieved by running Maven as follows:
+
+ mvn clean install -Dmaven.repo.local=/tmp/testrepo
+
+The command changes the local repository location from ~/.m2 to the
+directory passed as argument
+
+
+## Simulating a Release
+
+To test the release build without actually deploying the software, we have
+created a profile that will deploy to the local file system. You can
+simulate the release by running
+
+ mvn clean deploy -Pdist-local,marmotta-release,installer
+
+Please keep in mind that building a release involves creating digital
+signatures, so you will need a GPG key and a proper GPG configuration to run
+this task.
+
+Read more about [our release process](https://wiki.apache.org/marmotta/ReleaseProcess).

-Apache Marmotta
-===============
-
-This code repository contains the source-code for Apache Marmotta
-
-
-1. Building the Source Distribution
------------------------------------
-
-Apache Marmotta uses Maven to build, test, and install the software. A basic
-build requires downloading and installing Maven and then running:
-
-mvn clean install
-
-This will compile, package and test all Apache Marmotta modules and install
-it in your local Maven repository. In case you want to build your own
-projects based on some of the libraries provided by Apache Marmotta, this
-usually suffices.
-
-The default loglevel for most unit and integration tests executed during the
-build is INFO. To change the loglevel for either more or less output, you
-can pass the loglevel as system property:
-
-mvn clean install -Droot-level=TRACE|DEBUG|INFO|WARN|ERROR
-
-Note that some of the integration tests start up parts of the Marmotta
-platform during execution. The log level for these tests cannot be
-changed, as Marmotta is taking over the log configuration in these
-cases.
-
-2. Building, Running and Deploying the Wep Application
-------------------------------------------------------
-
-Apache Marmotta also includes a default configuration for building a Java
-Web Application that can be deployed in any Java Application Server. To
-build the web application, first run
-
-mvn clean install
-
-in the project root. Then change to the launchers/marmotta-webapp directory
-and run
-
-mvn package
-
-This will create a marmotta.war file in the target/ directory. You can
-deploy this archive to any Java Application Server by copying it into
-its deployment directory. More details can be found on:
-
-http://marmotta.apache.org/installation.html
-
-
-Alternatively, you can directly startup the Apache Marmotta Web Application
-from Maven with a default configuration suitable for development. To try this
-out, run
-
-mvn tomcat7:run
-
-wait until the system is started up and point your browser to
-http://localhost:8080
-

-guration of the system. Therefore, you can also start up the web application
-as follows:

+# Apache Marmotta Webapp Launcher
+
+This folder contains a JavaEE Web Application for launching Marmotta in any Servlet (>=3.0) container.
+
+Further details at the `src/main/doc/README.txt` file.
+
+## WAR
+
+For building the WAR just execute:
+
+ mvn package
+
+and you'll find the WAR file at `target/marmotta.war`.
+
+## Debian
+
+The build also provides supprt for Debian packages, just append the profile to the regular build command:
+
+ mvn package -Pdebian
+
+and you can find the `.deb` file under `target/`.
+
+## Docker
+
+It also comes with support for creating a Docker images that you can use for development or testing:
+
+1. Locate at the root of the source repository
+2. Build image: `docker build -t marmotta .`
+3. Run the container: `docker run -p 8080:8080 marmotta`
+4. Access Marmotta at [localhost:8080/marmotta](http://localhost:8080/marmotta) (IP address may be different, see information bellow).
+
+An official images is [available from Docker Hub](https://hub.docker.com/r/apache/marmotta/) as an automated
+build, so you just need to pull it from there to replace the second step above: `docker pull apache/marmotta`
+
+If you want to further work with the container, here some basic instructions:
+
+* List running containers: `docker ps` (appending `--filter "ancestor=marmotta` shows only the `marmotta` images, `-a` lists all)
+* Get details about the container: `docker inspect CONTAINER_ID`
+* Get basic statistics about the container: `docker stats [CONTAINERID]`
+* Commit the container changes to a new image: `docker commit [CONTAINERID] my-marmotta`
+* Stop the container: `docker stop [CONTAINERID]`
+* Start again the container: `docker start [CONTAINERID]`
+* Remove a container: `docker rm CONTAINER_ID`
+* Remove all containers `docker rm $(docker ps -a -q)`
+* List all images: `docker images`
+* Remove an image: `docker rmi IMAGE_ID`
+* Remove all images: `docker rmi $(docker images -q)`
+
+For further instructions, please take a look to the [Docker User Guide](https://docs.docker.com/userguide/).

+This repository implements an experimental high-performance backend for Apache Marmotta
+using LevelDB as storage and gRPC as communication channel between the Java frontend
+and the C++ backend.
+
+If it proves to be useful, the repository will eventually be merged into the main
+development branch of Apache Marmotta
+
+## Dependencies (C++)
+
+To compile the C++ backend, you need to have the following dependencies installed:
+
+ * libraptor (used for parsing/serializing in C++)
+ * librasqal (used for server-side SPARQL evaluation)
+ * libglog (logging)
+ * libgflags (command line arguments)
+ * libleveldb (database backend)
+ * libgrpc (gRPC runtime)
+ * libprotobuf (messaging, data model)
+
+With the exception of libgrpc and libprotobuf, all libraries are available in Linux repositories.
+Debian:
+
+ apt-get install libraptor2-dev librasqal3-dev libgoogle-glog-dev libgflags-dev libleveldb-dev
+
+The backend uses the new Proto 3 format and the gRPC SDK. These need to be installed separately;
+please follow the instructions at [https://github.com/grpc/grpc](https://github.com/grpc/grpc/blob/master/INSTALL).
+
+
+## Compilation (C++)
+
+The backend uses cmake to compile the modules. Create a new directory `build`, run cmake, and run make:
+
+ cd backend
+ mkdir build && cd build
+ cmake ..
+ make
+ cd ..
+
+## Compilation (Java)
+
+The frontend is compiled with Maven and depends on many Apache Marmotta modules to work. Build it with
+
+ mvn clean install
+
+## Running C++ Backend
+
+Start the backend from the cmake build directory as follows:
+
+ ./backend/build/persistence/marmotta_persistence -db /path/to/database -port 10000
+
+The binary accepts many different options. Please see `--help` for details.
+
+## Running Docker
+
+The C++ backend can be ran in the provided Docker image. You can build it:
+
+ docker build -t apachemarmotta/ostrich .
+
+Or fetch it [from Docker Hub](https://hub.docker.com/r/apachemarmotta/ostrich/):
+
+ docker pull apachemarmotta/ostrich
+
+Then you can run Ostrich as a container:
+
+ docker run -t -d -p 10000:10000 apachemarmotta/ostrich
+
+connecting normally to `localhost:10000`.
+
+## Running Sharding
+
+The repository contains an experimental implementation of a sharding server that proxies and
+distributes requests based on a hash calculation over statements. In heavy load environments,
+this is potentially much faster than running a single persistence backend. The setup requires
+several persistence backends (shards) and a sharding proxy. To experiment, you can start these
+on the same machine as follows:
+
+ ./backend/build/persistence/marmotta_persistence -db /path/to/shard1 -port 10001
+ ./backend/build/persistence/marmotta_persistence -db /path/to/shard2 -port 10002
+ ./backend/build/sharding/marmotta_sharding --port 10000 --backends localhost:10001,localhost:10002
+
+You can then access the sharding server through Marmotta like the persistence server. Running all instances
+on the same host is only useful for testing. In production environments, you would of course run all three
+(or more) instances on different hosts. Note that the number and order of backends should not change once
+data has been imported, because otherwise the hashing algorithm will do the wrong thing.
+
+## Running Apache Marmotta
+
+There is a `ostrich` Maven profile to run the webapp launcher:
+
+ cd launchers/marmotta-webapp
+ mvn tomcat7:run -Postrich
+
+Afterwards, point your browser to [localhost:8080](http://localhost:8080/).
+
+## Command Line Client
+
+A C++ command line client is available for very fast bulk imports and simple queries. To import
+a large turtle file, run:
+
+ ./client/marmotta_client --format=turtle import file.ttl
+
+The client connects by default to `localhost:10000` (change with `--host` and `--port` flags).

+# Abseil CMake Build Instructions
+
+Abseil comes with a CMake build script ([CMakeLists.txt](../CMakeLists.txt))
+that can be used on a wide range of platforms ("C" stands for cross-platform.).
+If you don't have CMake installed already, you can download it for free from
+<http://www.cmake.org/>.
+
+CMake works by generating native makefiles or build projects that can
+be used in the compiler environment of your choice.
+
+For API/ABI compatibility reasons, we strongly recommend building Abseil in a
+subdirectory of your project or as an embedded dependency.
+
+## Incorporating Abseil Into a CMake Project
+
+The recommendations below are similar to those for using CMake within the
+googletest framework
+(<https://github.com/google/googletest/blob/master/googletest/README.md#incorporating-into-an-existing-cmake-project>)
+
+### Step-by-Step Instructions
+
+1. If you want to build the Abseil tests, integrate the Abseil dependency
+[Google Test](https://github.com/google/googletest) into your CMake project. To disable Abseil tests, you have to pass
+`-DBUILD_TESTING=OFF` when configuring your project with CMake.
+
+2. Download Abseil and copy it into a subdirectory in your CMake project or add
+Abseil as a [git submodule](https://git-scm.com/docs/git-submodule) in your
+CMake project.
+
+3. You can then use the CMake command
+[`add_subdirectory()`](https://cmake.org/cmake/help/latest/command/add_subdirectory.html)
+to include Abseil directly in your CMake project.
+
+4. Add the **absl::** target you wish to use to the
+[`target_link_libraries()`](https://cmake.org/cmake/help/latest/command/target_link_libraries.html)
+section of your executable or of your library.<br>
+Here is a short CMakeLists.txt example of a project file using Abseil.
+
+```cmake
+cmake_minimum_required(VERSION 2.8.12)
+project(my_project)
+
+set(CMAKE_CXX_FLAGS "-std=c++11 -stdlib=libc++ ${CMAKE_CXX_FLAGS}")
+
+if(MSVC)
+ # /wd4005 macro-redefinition
+ # /wd4068 unknown pragma
+ # /wd4244 conversion from 'type1' to 'type2'
+ # /wd4267 conversion from 'size_t' to 'type2'
+ # /wd4800 force value to bool 'true' or 'false' (performance warning)
+ add_compile_options(/wd4005 /wd4068 /wd4244 /wd4267 /wd4800)
+ add_definitions(/DNOMINMAX /DWIN32_LEAN_AND_MEAN=1 /D_CRT_SECURE_NO_WARNINGS)
+endif()
+
+add_subdirectory(googletest)
+add_subdirectory(cctz)
+add_subdirectory(abseil-cpp)
+
+add_executable(my_exe source.cpp)
+target_link_libraries(my_exe absl::base absl::synchronization absl::strings)
+```
+
+### Available Abseil CMake Public Targets
+
+Here's a non-exhaustive list of Abseil CMake public targets:
+
+```cmake
+absl::base
+absl::algorithm
+absl::container
+absl::debugging
+absl::memory
+absl::meta
+absl::numeric
+absl::strings
+absl::synchronization
+absl::time
+absl::utility
+```

+# How to Contribute to Abseil
+
+We'd love to accept your patches and contributions to this project. There are
+just a few small guidelines you need to follow.
+
+NOTE: If you are new to GitHub, please start by reading [Pull Request
+howto](https://help.github.com/articles/about-pull-requests/)
+
+## Contributor License Agreement
+
+Contributions to this project must be accompanied by a Contributor License
+Agreement. You (or your employer) retain the copyright to your contribution,
+this simply gives us permission to use and redistribute your contributions as
+part of the project. Head over to <https://cla.developers.google.com/> to see
+your current agreements on file or to sign a new one.
+
+You generally only need to submit a CLA once, so if you've already submitted one
+(even if it was for a different project), you probably don't need to do it
+again.
+
+## Coding Style
+
+To keep the source consistent, readable, diffable and easy to merge, we use a
+fairly rigid coding style, as defined by the
+[google-styleguide](https://github.com/google/styleguide) project. All patches
+will be expected to conform to the style outlined
+[here](https://google.github.io/styleguide/cppguide.html).
+
+## Guidelines for Pull Requests
+
+* If you are a Googler, it is preferable to first create an internal CL and
+ have it reviewed and submitted. The code propagation process will deliver
+ the change to GitHub.
+
+* Create **small PRs** that are narrowly focused on **addressing a single
+ concern**. We often receive PRs that are trying to fix several things at a
+ time, but if only one fix is considered acceptable, nothing gets merged and
+ both author's & review's time is wasted. Create more PRs to address
+ different concerns and everyone will be happy.
+
+* For speculative changes, consider opening an [Abseil
+ issue](https://github.com/abseil/abseil-cpp/issues) and discussing it first.
+ If you are suggesting a behavioral or API change, consider starting with an
+ [Abseil proposal template](ABSEIL_ISSUE_TEMPLATE.md).
+
+* Provide a good **PR description** as a record of **what** change is being
+ made and **why** it was made. Link to a GitHub issue if it exists.
+
+* Don't fix code style and formatting unless you are already changing that
+ line to address an issue. Formatting of modified lines may be done using
+ `git clang-format`. PRs with irrelevant changes won't be merged. If
+ you do want to fix formatting or style, do that in a separate PR.
+
+* Unless your PR is trivial, you should expect there will be reviewer comments
+ that you'll need to address before merging. We expect you to be reasonably
+ responsive to those comments, otherwise the PR will be closed after 2-3
+ weeks of inactivity.
+
+* Maintain **clean commit history** and use **meaningful commit messages**.
+ PRs with messy commit history are difficult to review and won't be merged.
+ Use `rebase -i upstream/master` to curate your commit history and/or to
+ bring in latest changes from master (but avoid rebasing in the middle of a
+ code review).
+
+* Keep your PR up to date with upstream/master (if there are merge conflicts,
+ we can't really merge your change).
+
+* **All tests need to be passing** before your change can be merged. We
+ recommend you **run tests locally** (see below)
+
+* Exceptions to the rules can be made if there's a compelling reason for doing
+ so. That is - the rules are here to serve us, not the other way around, and
+ the rules need to be serving their intended purpose to be valuable.
+
+* All submissions, including submissions by project members, require review.
+
+## Running Tests
+
+Use "bazel test <>" functionality to run the unit tests.
+
+Prerequisites for building and running tests are listed in
+[README.md](README.md)
+
+## Abseil Committers
+
+The current members of the Abseil engineering team are the only committers at
+present.
+
+## Release Process
+
+Abseil lives at head, where latest-and-greatest code can be found.

+# Abseil - C++ Common Libraries
+
+The repository contains the Abseil C++ library code. Abseil is an open-source
+collection of C++ code (compliant to C++11) designed to augment the C++
+standard library.

+## About Abseil
+
+Abseil is an open-source collection of C++ library code designed to augment
+the C++ standard library. The Abseil library code is collected from Google's
+own C++ code base, has been extensively tested and used in production, and
+is the same code we depend on in our daily coding lives.
+
+In some cases, Abseil provides pieces missing from the C++ standard; in
+others, Abseil provides alternatives to the standard for special needs
+we've found through usage in the Google code base. We denote those cases
+clearly within the library code we provide you.
+
+Abseil is not meant to be a competitor to the standard library; we've
+just found that many of these utilities serve a purpose within our code
+base, and we now want to provide those resources to the C++ community as
+a whole.
+
+<a name="quickstart"></a>
+## Quickstart
+
+If you want to just get started, make sure you at least run through the
+[Abseil Quickstart](https://abseil.io/docs/cpp/quickstart). The Quickstart
+contains information about setting up your development environment, downloading
+the Abseil code, running tests, and getting a simple binary working.
+
+<a name="build"></a>
+## Building Abseil
+
+[Bazel](http://bazel.build) is the official build system for Abseil,
+which is supported on most major platforms (Linux, Windows, MacOS, for example)
+and compilers. See the [quickstart](https://abseil.io/docs/cpp/quickstart) for
+more information on building Abseil using the Bazel build system.
+
+<a name="cmake"></a>
+If you require CMake support, please check the
+[CMake build instructions](CMake/README.md).
+
+## Codemap
+
+Abseil contains the following C++ library components:
+
+* [`base`](absl/base/) Abseil Fundamentals
+ <br /> The `base` library contains initialization code and other code which
+ all other Abseil code depends on. Code within `base` may not depend on any
+ other code (other than the C++ standard library).
+* [`algorithm`](absl/algorithm/)
+ <br /> The `algorithm` library contains additions to the C++ `<algorithm>`
+ library and container-based versions of such algorithms.
+* [`container`](absl/container/)
+ <br /> The `container` library contains additional STL-style containers.
+* [`debugging`](absl/debugging/)
+ <br /> The `debugging` library contains code useful for enabling leak
+ checks. Future updates will add stacktrace and symbolization utilities.
+* [`memory`](absl/memory/)
+ <br /> The `memory` library contains C++11-compatible versions of
+ `std::make_unique()` and related memory management facilities.
+* [`meta`](absl/meta/)
+ <br /> The `meta` library contains C++11-compatible versions of type checks
+ available within C++14 and C++17 versions of the C++ `<type_traits>` library.
+* [`numeric`](absl/numeric/)
+ <br /> The `numeric` library contains C++11-compatible 128-bit integers.
+* [`strings`](absl/strings/)
+ <br /> The `strings` library contains a variety of strings routines and
+ utilities, including a C++11-compatible version of the C++17
+ `std::string_view` type.
+* [`synchronization`](absl/synchronization/)
+ <br /> The `synchronization` library contains concurrency primitives (Abseil's
+ `absl::Mutex` class, an alternative to `std::mutex`) and a variety of
+ synchronization abstractions.
+* [`time`](absl/time/)
+ <br /> The `time` library contains abstractions for computing with absolute
+ points in time, durations of time, and formatting and parsing time within
+ time zones.
+* [`types`](absl/types/)
+ <br /> The `types` library contains non-container utility types, like a
+ C++11-compatible version of the C++17 `std::optional` type.
+
+## License
+
+The Abseil C++ library is licensed under the terms of the Apache
+license. See [LICENSE](LICENSE) for more information.

+* Read [Why Adopt Abseil](http://abseil.io/about/philosophy) to understand our
+ design philosophy.
+* Peruse our
+ [Abseil Compatibility Guarantees](http://abseil.io/about/compatibility) to
+ understand both what we promise to you, and what we expect of you in return.

+//
+// * Algorithmic <iterator> functions
+// * Algorithmic <numeric> functions
+// * <algorithm> functions
+//
+// The standard library functions operate on iterator ranges; the functions
+// within this API operate on containers, though many return iterator ranges.
+//
+// All functions within this API are named with a `c_` prefix. Calls such as
+// `absl::c_xx(container, ...) are equivalent to std:: functions such as
+// `std::xx(std::begin(cont), std::end(cont), ...)`. Functions that act on
+// iterators but not conceptually on iterator ranges (e.g. `std::iter_swap`)
+// have no equivalent here.
+//
+// For template parameter and variable naming, `C` indicates the container type
+// to which the function is applied, `Pred` indicates the predicate object type
+// to be used by the function and `T` indicates the applicable element type.

+// This header file defines macros for declaring attributes for functions,
+// types, and variables.
+//
+// These macros are used within Abseil and allow the compiler to optimize, where
+// applicable, certain function calls.
+//
+// This file is used for both C and C++!
+//
+// Most macros here are exposing GCC or Clang features, and are stubbed out for
+// other compilers.
+//
+// GCC attributes documentation:
+// https://gcc.gnu.org/onlinedocs/gcc-4.7.0/gcc/Function-Attributes.html
+// https://gcc.gnu.org/onlinedocs/gcc-4.7.0/gcc/Variable-Attributes.html
+// https://gcc.gnu.org/onlinedocs/gcc-4.7.0/gcc/Type-Attributes.html
+//
+// Most attributes in this file are already supported by GCC 4.7. However, some
+// of them are not supported in older version of Clang. Thus, we check
+// `__has_attribute()` first. If the check fails, we check if we are on GCC and
+// assume the attribute exists on GCC (which is verified on GCC 4.7).
+//
+// -----------------------------------------------------------------------------
+// Sanitizer Attributes
+// -----------------------------------------------------------------------------
+//
+// Sanitizer-related attributes are not "defined" in this file (and indeed
+// are not defined as such in any file). To utilize the following
+// sanitizer-related attributes within your builds, define the following macros
+// within your build using a `-D` flag, along with the given value for
+// `-fsanitize`:
+//
+// * `ADDRESS_SANITIZER` + `-fsanitize=address` (Clang, GCC 4.8)
+// * `MEMORY_SANITIZER` + `-fsanitize=memory` (Clang-only)
+// * `THREAD_SANITIZER + `-fsanitize=thread` (Clang, GCC 4.8+)
+// * `UNDEFINED_BEHAVIOR_SANITIZER` + `-fsanitize=undefined` (Clang, GCC 4.9+)
+// * `CONTROL_FLOW_INTEGRITY` + -fsanitize=cfi (Clang-only)
+//
+// Example:
+//
+// // Enable branches in the Abseil code that are tagged for ASan:
+// $ bazel -D ADDRESS_SANITIZER -fsanitize=address *target*
+//
+// Since these macro names are only supported by GCC and Clang, we only check
+// for `__GNUC__` (GCC or Clang) and the above macros.

+// implicit_cast()
+//
+// Performs an implicit conversion between types following the language
+// rules for implicit conversion; if an implicit conversion is otherwise
+// allowed by the language in the given context, this function performs such an
+// implicit conversion.
+//
+// Example:
+//
+// // If the context allows implicit conversion:
+// From from;
+// To to = from;
+//
+// // Such code can be replaced by:
+// implicit_cast<To>(from);
+//
+// An `implicit_cast()` may also be used to annotate numeric type conversions
+// that, although safe, may produce compiler warnings (such as `long` to `int`).
+// Additionally, an `implicit_cast()` is also useful within return statements to
+// indicate a specific implicit conversion is being undertaken.
+//
+// Example:
+//
+// return implicit_cast<double>(size_in_bytes) / capacity_;
+//
+// Annotating code with `implicit_cast()` allows you to explicitly select
+// particular overloads and template instantiations, while providing a safer
+// cast than `reinterpret_cast()` or `static_cast()`.
+//
+// Additionally, an `implicit_cast()` can be used to allow upcasting within a
+// type hierarchy where incorrect use of `static_cast()` could accidentally
+// allow downcasting.
+//
+// Finally, an `implicit_cast()` can be used to perform implicit conversions
+// from unrelated types that otherwise couldn't be implicitly cast directly;
+// C++ will normally only implicitly cast "one step" in such conversions.
+//
+// That is, if C is a type which can be implicitly converted to B, with B being
+// a type that can be implicitly converted to A, an `implicit_cast()` can be
+// used to convert C to B (which the compiler can then implicitly convert to A
+// using language rules).
+//
+// Example:
+//
+// // Assume an object C is convertible to B, which is implicitly convertible
+// // to A
+// A a = implicit_cast<B>(C);
+//
+// Such implicit cast chaining may be useful within template logic.
+template <typename To>

+
+// bit_cast()
+//
+// Performs a bitwise cast on a type without changing the underlying bit
+// representation of that type's value. The two types must be of the same size
+// and both types must be trivially copyable. As with most casts, use with
+// caution. A `bit_cast()` might be needed when you need to temporarily treat a
+// type as some other type, such as in the following cases:
+//
+// * Serialization (casting temporarily to `char *` for those purposes is
+// always allowed by the C++ standard)
+// * Managing the individual bits of a type within mathematical operations
+// that are not normally accessible through that type
+// * Casting non-pointer types to pointer types (casting the other way is
+// allowed by `reinterpret_cast()` but round-trips cannot occur the other
+// way).
+//
+// Example:
+//
+// float f = 3.14159265358979;
+// int i = bit_cast<int32_t>(f);
+// // i = 0x40490fdb
+//
+// Casting non-pointer types to pointer types and then dereferencing them
+// traditionally produces undefined behavior.
+//
+// Example:
+//
+// // WRONG
+// float f = 3.14159265358979; // WRONG
+// int i = * reinterpret_cast<int*>(&f); // WRONG
+//
+// The address-casting method produces undefined behavior according to the ISO
+// C++ specification section [basic.lval]. Roughly, this section says: if an
+// object in memory has one type, and a program accesses it with a different
+// type, the result is undefined behavior for most values of "different type".
+//
+// Such casting results in type punning: holding an object in memory of one type
+// and reading its bits back using a different type. A `bit_cast()` avoids this
+// issue by implementing its casts using `memcpy()`, which avoids introducing
+// this undefined behavior.
+template <typename Dest, typename Source>

+/* This file defines dynamic annotations for use with dynamic analysis
+ tool such as valgrind, PIN, etc.
+
+ Dynamic annotation is a source code annotation that affects
+ the generated code (that is, the annotation is not a comment).
+ Each such annotation is attached to a particular
+ instruction and/or to a particular object (address) in the program.
+
+ The annotations that should be used by users are macros in all upper-case
+ (e.g., ANNOTATE_THREAD_NAME).
+
+ Actual implementation of these macros may differ depending on the
+ dynamic analysis tool being used.
+
+ This file supports the following configurations:
+ - Dynamic Annotations enabled (with static thread-safety warnings disabled).
+ In this case, macros expand to functions implemented by Thread Sanitizer,
+ when building with TSan. When not provided an external implementation,
+ dynamic_annotations.cc provides no-op implementations.
+
+ - Static Clang thread-safety warnings enabled.
+ When building with a Clang compiler that supports thread-safety warnings,
+ a subset of annotations can be statically-checked at compile-time. We
+ expand these macros to static-inline functions that can be analyzed for
+ thread-safety, but afterwards elided when building the final binary.
+
+ - All annotations are disabled.
+ If neither Dynamic Annotations nor Clang thread-safety warnings are
+ enabled, then all annotation-macros expand to empty. */

+////////////////////////////////////////////////////////////////////////////////
+// Macro: ABSL_INTERNAL_INLINE_CONSTEXPR(type, name, init)
+//
+// Description:
+// Expands to the equivalent of an inline constexpr instance of the specified
+// `type` and `name`, initialized to the value `init`. If the compiler being
+// used is detected as supporting actual inline variables as a language
+// feature, then the macro expands to an actual inline variable definition.
+//
+// Requires:
+// `type` is a type that is usable in an extern variable declaration.
+//
+// Requires: `name` is a valid identifier
+//
+// Requires:
+// `init` is an expression that can be used in the following definition:
+// constexpr type name = init;
+//
+// Usage:
+//
+// // Equivalent to: `inline constexpr size_t variant_npos = -1;`
+// ABSL_INTERNAL_INLINE_CONSTEXPR(size_t, variant_npos, -1);
+//
+// Differences in implementation:
+// For a direct, language-level inline variable, decltype(name) will be the
+// type that was specified along with const qualification, whereas for
+// emulated inline variables, decltype(name) may be different (in practice
+// it will likely be a reference type).

+// Most users requiring mutual exclusion should use Mutex.
+// SpinLock is provided for use in three situations:
+// - for use in code that Mutex itself depends on
+// - to get a faster fast-path release under low contention (without an
+// atomic read-modify-write) In return, SpinLock has worse behaviour under
+// contention, which is why Mutex is preferred in most situations.
+// - for async signal safety (see below)
+
+// SpinLock is async signal safe. If a spinlock is used within a signal
+// handler, all code that acquires the lock must ensure that the signal cannot
+// arrive while they are holding the lock. Typically, this is done by blocking
+// the signal.

+// On some platforms, like ARM, the copy functions can be more efficient

+//
+// It is possible to implement all of these these using constant-length memcpy
+// calls, which is portable and will usually be inlined into simple loads and

+// happens in a pass that's quite late in compilation, which means the resulting
+// loads and stores cannot participate in many other optimizations, leading to
+// overall worse code.

+//
+// Returns the # of elements in an array as a compile-time constant, which can
+// be used in defining new arrays. If you use this macro on a pointer by
+// mistake, you will get a compile-time error.
+//
+// Note: this template function declaration is used in defining arraysize.
+// Note that the function doesn't need an implementation, as we only

+
+// kLinkerInitialized
+//
+// An enum used only as a constructor argument to indicate that a variable has
+// static storage duration, and that the constructor should do nothing to its
+// state. Use of this macro indicates to the reader that it is legal to
+// declare a static instance of the class, provided the constructor is given
+// the absl::base_internal::kLinkerInitialized argument.
+//
+// Normally, it is unsafe to declare a static variable that has a constructor or
+// a destructor because invocation order is undefined. However, if the type can
+// be zero-initialized (which the loader does for static variables) into a valid
+// state and the type's destructor does not affect storage, then a constructor
+// for static initialization can be declared.
+//
+// Example:
+// // Declaration
+// explicit MyClass(absl::base_internal:LinkerInitialized x) {}
+//
+// // Invocation
+// static MyClass my_global(absl::base_internal::kLinkerInitialized);

+// ABSL_FALLTHROUGH_INTENDED
+//
+// Annotates implicit fall-through between switch labels, allowing a case to
+// indicate intentional fallthrough and turn off warnings about any lack of a
+// `break` statement. The ABSL_FALLTHROUGH_INTENDED macro should be followed by
+// a semicolon and can be used in most places where `break` can, provided that
+// no statements exist between it and the next switch label.
+//
+// Example:
+//
+// switch (x) {
+// case 40:
+// case 41:
+// if (truth_is_out_there) {
+// ++x;
+// ABSL_FALLTHROUGH_INTENDED; // Use instead of/along with annotations
+// // in comments
+// } else {
+// return x;
+// }
+// case 42:
+// ...
+//
+// Notes: when compiled with clang in C++11 mode, the ABSL_FALLTHROUGH_INTENDED
+// macro is expanded to the [[clang::fallthrough]] attribute, which is analysed
+// when performing switch labels fall-through diagnostic
+// (`-Wimplicit-fallthrough`). See clang documentation on language extensions
+// for details:
+// http://clang.llvm.org/docs/AttributeReference.html#fallthrough-clang-fallthrough

+// This header file contains macro definitions for thread safety annotations
+// that allow developers to document the locking policies of multi-threaded
+// code. The annotations can also help program analysis tools to identify
+// potential thread safety issues.
+//
+//
+// These annotations are implemented using compiler attributes. Using the macros
+// defined here instead of raw attributes allow for portability and future
+// compatibility.
+//
+// When referring to mutexes in the arguments of the attributes, you should
+// use variable names or more complex expressions (e.g. my_object->mutex_)
+// that evaluate to a concrete mutex object whenever possible. If the mutex
+// you want to refer to is not in scope, you may use a member pointer
+// (e.g. &MyClass::mutex_) to refer to a mutex in some (unknown) object.

+// GUARDED_BY()
+//
+// Documents if a shared field or global variable needs to be protected by a
+// mutex. GUARDED_BY() allows the user to specify a particular mutex that
+// should be held when accessing the annotated variable.
+//
+// Although this annotation (and PT_GUARDED_BY, below) cannot be applied to
+// local variables, a local variable and its associated mutex can often be
+// combined into a small class or struct, thereby allowing the annotation.
+//
+// Example:
+//
+// class Foo {
+// Mutex mu_;
+// int p1_ GUARDED_BY(mu_);
+// ...
+// };

+//
+// Example:
+// class Foo {
+// Mutex mu_;
+// int *p1_ PT_GUARDED_BY(mu_);
+// ...
+// };
+//
+// Note that a pointer variable to a shared memory location could itself be a
+// shared variable.
+//
+// Example:
+//
+// // `q_`, guarded by `mu1_`, points to a shared memory location that is
+// // guarded by `mu2_`:

+// (i.e. You don't have to annotate both locks with both ACQUIRED_AFTER
+// and ACQUIRED_BEFORE.)
+//
+// As with GUARDED_BY, this is only applicable to mutexes that are shared

+// This header file contains the declaration and definition of an "inlined
+// vector" which behaves in an equivalent fashion to a `std::vector`, except
+// that storage for small sequences of the vector are provided inline without
+// requiring any heap allocation.
+
+// An `absl::InlinedVector<T,N>` specifies the size N at which to inline as one
+// of its template parameters. Vectors of length <= N are provided inline.
+// Typically N is very small (e.g., 4) so that sequences that are expected to be
+// short do not require allocations.
+
+// An `absl::InlinedVector` does not usually require a specific allocator; if
+// the inlined vector grows beyond its initial constraints, it will need to
+// allocate (as any normal `std::vector` would) and it will generally use the
+// default allocator in that case; optionally, a custom allocator may be
+// specified using an `absl::InlinedVector<T,N,A>` construction.

+// - Support GNU extensions not defined in the Itanium C++ ABI
+// - <prefix> and <template-prefix> are combined to avoid infinite loop
+// - Reorder patterns to shorten the code
+// - Reorder patterns to give greedier functions precedence
+// We'll mark "Less greedy than" for these cases in the code
+//
+// Each parsing function changes the parse state and returns true on
+// success, or returns false and doesn't change the parse state (note:
+// the parse-steps counter increases regardless of success or failure).
+// To ensure that the parse state isn't changed in the latter case, we
+// save the original state before we call multiple parsing functions
+// consecutively with &&, and restore it if unsuccessful. See
+// ParseEncoding() as an example of this convention. We follow the
+// convention throughout the code.
+//
+// Originally we tried to do demangling without following the full ABI
+// syntax but it turned out we needed to follow the full syntax to
+// parse complicated cases like nested template arguments. Note that
+// implementing a full-fledged demangler isn't trivial (libiberty's
+// cp-demangle.c has +4300 lines).
+//
+// Note that (foo) in <(foo) ...> is a modifier to be ignored.

+// An async-signal-safe and thread-safe demangler for Itanium C++ ABI
+// (aka G++ V3 ABI).
+//
+// The demangler is implemented to be used in async signal handlers to
+// symbolize stack traces. We cannot use libstdc++'s
+// abi::__cxa_demangle() in such signal handlers since it's not async
+// signal safe (it uses malloc() internally).
+//
+// Note that this demangler doesn't support full demangling. More
+// specifically, it doesn't print types of function parameters and
+// types of template arguments. It just skips them. However, it's
+// still very useful to extract basic information such as class,
+// function, constructor, destructor, and operator names.
+//
+// See the implementation note in demangle.cc if you are interested.
+//
+// Example:
+//
+// | Mangled Name | The Demangler | abi::__cxa_demangle()
+// |---------------|---------------|-----------------------
+// | _Z1fv | f() | f()
+// | _Z1fi | f() | f(int)
+// | _Z3foo3bar | foo() | foo(bar)
+// | _Z1fIiEvi | f<>() | void f<int>(int)
+// | _ZN1N1fE | N::f | N::f
+// | _ZN3Foo3BarEv | Foo::Bar() | Foo::Bar()
+// | _Zrm1XS_" | operator%() | operator%(X, X)
+// | _ZN3FooC1Ev | Foo::Foo() | Foo::Foo()
+// | _Z1fSs | f() | f(std::basic_string<char,
+// | | | std::char_traits<char>,
+// | | | std::allocator<char> >)
+//
+// See the unit test for more examples.
+//
+// Note: we might want to write demanglers for ABIs other than Itanium
+// C++ ABI in the future.

+// Produces a stack trace for Windows. Normally, one could use
+// stacktrace_x86-inl.h or stacktrace_x86_64-inl.h -- and indeed, that
+// should work for binaries compiled using MSVC in "debug" mode.
+// However, in "release" mode, Windows uses frame-pointer
+// optimization, which makes getting a stack trace very difficult.
+//
+// There are several approaches one can take. One is to use Windows
+// intrinsics like StackWalk64. These can work, but have restrictions
+// on how successful they can be. Another attempt is to write a
+// version of stacktrace_x86-inl.h that has heuristic support for
+// dealing with FPO, similar to what WinDbg does (see
+// http://www.nynaeve.net/?p=97). There are (non-working) examples of
+// these approaches, complete with TODOs, in stacktrace_win32-inl.h#1
+//
+// The solution we've ended up doing is to call the undocumented
+// windows function RtlCaptureStackBackTrace, which probably doesn't
+// work with FPO but at least is fast, and doesn't require a symbol

+// Creates a `std::unique_ptr<>`, while avoiding issues creating temporaries
+// during the construction process. `absl::make_unique<>` also avoids redundant
+// type declarations, by avoiding the need to explicitly use the `new` operator.
+//
+// This implementation of `absl::make_unique<>` is designed for C++11 code and
+// will be replaced in C++14 by the equivalent `std::make_unique<>` abstraction.
+// `absl::make_unique<>` is designed to be 100% compatible with
+// `std::make_unique<>` so that the eventual migration will involve a simple
+// rename operation.
+//
+// For more background on why `std::unique_ptr<T>(new T(a,b))` is problematic,
+// see Herb Sutter's explanation on
+// (Exception-Safe Function Calls)[http://herbsutter.com/gotw/_102/].
+// (In general, reviewers should treat `new T(a,b)` with scrutiny.)
+//
+// Example usage:
+//
+// auto p = make_unique<X>(args...); // 'p' is a std::unique_ptr<X>
+// auto pa = make_unique<X[]>(5); // 'pa' is a std::unique_ptr<X[]>
+//
+// Three overloads of `absl::make_unique` are required:
+//
+// - For non-array T:
+//
+// Allocates a T with `new T(std::forward<Args> args...)`,
+// forwarding all `args` to T's constructor.
+// Returns a `std::unique_ptr<T>` owning that object.
+//
+// - For an array of unknown bounds T[]:
+//
+// `absl::make_unique<>` will allocate an array T of type U[] with
+// `new U[n]()` and return a `std::unique_ptr<U[]>` owning that array.
+//
+// Note that 'U[n]()' is different from 'U[n]', and elements will be
+// value-initialized. Note as well that `std::unique_ptr` will perform its
+// own destruction of the array elements upon leaving scope, even though
+// the array [] does not have a default destructor.
+//
+// NOTE: an array of unknown bounds T[] may still be (and often will be)
+// initialized to have a size, and will still use this overload. E.g:
+//
+// auto my_array = absl::make_unique<int[]>(10);
+//
+// - For an array of known bounds T[N]:
+//
+// `absl::make_unique<>` is deleted (like with `std::make_unique<>`) as
+// this overload is not useful.
+//
+// NOTE: an array of known bounds T[N] is not considered a useful
+// construction, and may cause undefined behavior in templates. E.g:
+//
+// auto my_array = absl::make_unique<int[10]>();
+//
+// In those cases, of course, you can still use the overload above and
+// simply initialize it to its desired size:
+//
+// auto my_array = absl::make_unique<int[]>(10);
+
+// `absl::make_unique` overload for non-array types.
+template <typename T, typename... Args>
+typename memory_internal::MakeUniqueResult<T>::scalar make_unique(

+ return std::unique_ptr<T>(new T(std::forward<Args>(args)...));
+}
+
+// `absl::make_unique` overload for an array T[] of unknown bounds.
+// The array allocation needs to use the `new T[size]` form and cannot take
+// element constructor arguments. The `std::unique_ptr` will manage destructing
+// these array elements.

+
+// -----------------------------------------------------------------------------
+// Function Template: RawPtr()
+// -----------------------------------------------------------------------------
+//
+// Extracts the raw pointer from a pointer-like value `ptr`. `absl::RawPtr` is
+// useful within templates that need to handle a complement of raw pointers,
+// `std::nullptr_t`, and smart pointers.
+template <typename T>

+// -----------------------------------------------------------------------------
+// Function Template: ShareUniquePtr()
+// -----------------------------------------------------------------------------
+//
+// Adopts a `std::unique_ptr` rvalue and returns a `std::shared_ptr` of deduced
+// type. Ownership (if any) of the held value is transferred to the returned
+// shared pointer.
+//
+// Example:
+//
+// auto up = absl::make_unique<int>(10);
+// auto sp = absl::ShareUniquePtr(std::move(up)); // shared_ptr<int>
+// CHECK_EQ(*sp, 10);
+// CHECK(up == nullptr);
+//
+// Note that this conversion is correct even when T is an array type, and more
+// generally it works for *any* deleter of the `unique_ptr` (single-object
+// deleter, array deleter, or any custom deleter), since the deleter is adopted
+// by the shared pointer as well. The deleter is copied (unless it is a
+// reference).
+//
+// Implements the resolution of [LWG 2415](http://wg21.link/lwg2415), by which a

+// In GCC/Clang, std::is_trivially_constructible requires that the destructor is
+// trivial. However, MSVC doesn't require that. This results in different
+// behavior when checking is_trivially_constructible on any type with
+// nontrivial destructor. Since absl::is_trivially_default_constructible and
+// absl::is_trivially_copy_constructible both follows Clang/GCC's interpretation
+// and check is_trivially_destructible, it results in inconsistency with
+// std::is_trivially_xxx_constructible on MSVC. This macro is used to work
+// around this issue in test. In practice, a trivially constructible type
+// should also be trivially destructible.

+// uint128
+//
+// An unsigned 128-bit integer type. The API is meant to mimic an intrinsic type
+// as closely as is practical, including exhibiting undefined behavior in
+// analogous cases (e.g. division by zero). This type is intended to be a
+// drop-in replacement once C++ supports an intrinsic `uint128_t` type; when
+// that occurs, existing well-behaved uses of `uint128` will continue to work
+// using that new type.
+//
+// Note: code written with this type will continue to compile once `uint128_t`
+// is introduced, provided the replacement helper functions
+// `Uint128(Low|High)64()` and `MakeUint128()` are made.
+//
+// A `uint128` supports the following:
+//
+// * Implicit construction from integral types
+// * Explicit conversion to integral types
+//
+// Additionally, if your compiler supports `__int128`, `uint128` is
+// interoperable with that type. (Abseil checks for this compatibility through
+// the `ABSL_HAVE_INTRINSIC_INT128` macro.)
+//
+// However, a `uint128` differs from intrinsic integral types in the following
+// ways:
+//
+// * Errors on implicit conversions that do not preserve value (such as
+// loss of precision when converting to float values).
+// * Requires explicit construction from and conversion to floating point
+// types.
+// * Conversion to integral types requires an explicit static_cast() to
+// mimic use of the `-Wnarrowing` compiler flag.
+// * The alignment requirement of `uint128` may differ from that of an
+// intrinsic 128-bit integer type depending on platform and build
+// configuration.
+//
+// Example:
+//
+// float y = absl::Uint128Max(); // Error. uint128 cannot be implicitly
+// // converted to float.
+//
+// absl::uint128 v;
+// uint64_t i = v; // Error
+// uint64_t i = static_cast<uint64_t>(v); // OK

+// header file.
+//
+// C++ implementations provide <ctype.h> functionality based on their
+// C environment locale. In general, reliance on such a locale is not ideal, as
+// the locale standard is problematic (and may not return invariant information
+// for the same character set, for example). These `ascii_*()` functions are
+// hard-wired for standard ASCII, much faster, and guaranteed to behave
+// consistently. They will never be overloaded, nor will their function
+// signature change.

+// `ascii_isprint()`, `ascii_ispunct()`, `ascii_isspace()`, `ascii_isupper()`,
+// `ascii_isxdigit()`
+// Analogous to the <ctype.h> functions with similar names, these
+// functions take an unsigned char and return a bool, based on whether the
+// character matches the condition specified.
+//
+// If the input character has a numerical value greater than 127, these
+// functions return `false`.
+//
+// `ascii_tolower()`, `ascii_toupper()`
+// Analogous to the <ctype.h> functions with similar names, these functions

+//
+// If the input character is not an ASCII {lower,upper}-case letter (including
+// numerical values greater than 127) then the functions return the same value

+// escape sequences (http://en.cppreference.com/w/cpp/language/escape) into
+// their proper code point equivalents, returning `true` if successful.
+//
+// The following unescape sequences can be handled:
+//
+// * ASCII escape sequences ('\n','\r','\\', etc.) to their ASCII equivalents
+// * Octal escape sequences ('\nnn') to byte nnn. The unescaped value must
+// resolve to a single byte or an error will occur. E.g. values greater than
+// 0xff will produce an error.
+// * Hexadecimal escape sequences ('\xnn') to byte nn. While an arbitrary
+// number of following digits are allowed, the unescaped value must resolve
+// to a single byte or an error will occur. E.g. '\x0045' is equivalent to
+// '\x45', but '\x1234' will produce an error.
+// * Unicode escape sequences ('\unnnn' for exactly four hex digits or
+// '\Unnnnnnnn' for exactly eight hex digits, which will be encoded in
+// UTF-8. (E.g., `\u2019` unescapes to the three bytes 0xE2, 0x80, and
+// 0x99).
+//
+//
+// If any errors are encountered, this function returns `false` and stores the
+// first encountered error in `error`. To disable error reporting, set `error`
+// to `nullptr` or use the overload with no error reporting below.
+//
+// Example:
+//

+// These routines provide mem versions of standard C std::string routines,
+// such as strpbrk. They function exactly the same as the str versions,
+// so if you wonder what they are, replace the word "mem" by
+// "str" and check out the man page. I could return void*, as the
+// strutil.h mem*() routines tend to do, but I return char* instead
+// since this is by far the most common way these functions are called.
+//
+// The difference between the mem and str versions is the mem version
+// takes a pointer and a length, rather than a '\0'-terminated std::string.
+// The memcase* routines defined here assume the locale is "C"
+// (they use absl::ascii_tolower instead of tolower).
+//
+// These routines are based on the BSD library.
+//
+// Here's a list of routines from std::string.h, and their mem analogues.
+// Functions in lowercase are defined in std::string.h; those in UPPERCASE
+// are defined here:
+//
+// strlen --
+// strcat strncat MEMCAT
+// strcpy strncpy memcpy
+// -- memccpy (very cool function, btw)
+// -- memmove
+// -- memset
+// strcmp strncmp memcmp
+// strcasecmp strncasecmp MEMCASECMP
+// strchr memchr
+// strcoll --
+// strxfrm --
+// strdup strndup MEMDUP
+// strrchr MEMRCHR
+// strspn MEMSPN
+// strcspn MEMCSPN
+// strpbrk MEMPBRK
+// strstr MEMSTR MEMMEM
+// (g)strcasestr MEMCASESTR MEMCASEMEM
+// strtok --
+// strprefix MEMPREFIX (strprefix is from strutil.h)
+// strcaseprefix MEMCASEPREFIX (strcaseprefix is from strutil.h)
+// strsuffix MEMSUFFIX (strsuffix is from strutil.h)
+// strcasesuffix MEMCASESUFFIX (strcasesuffix is from strutil.h)
+// -- MEMIS

+//
+// This package contains functions for efficiently concatenating and appending
+// strings: `StrCat()` and `StrAppend()`. Most of the work within these routines
+// is actually handled through use of a special AlphaNum type, which was
+// designed to be used as a parameter type that efficiently manages conversion
+// to strings and avoids copies in the above operations.
+//
+// Any routine accepting either a std::string or a number may accept `AlphaNum`.
+// The basic idea is that by accepting a `const AlphaNum &` as an argument
+// to your function, your callers will automagically convert bools, integers,
+// and floating point values to strings for you.
+//
+// NOTE: Use of `AlphaNum` outside of the //absl/strings package is unsupported
+// except for the specific case of function parameters of type `AlphaNum` or
+// `const AlphaNum &`. In particular, instantiating `AlphaNum` directly as a
+// stack variable is not supported.
+//
+// Conversion from 8-bit values is not accepted because, if it were, then an
+// attempt to pass ':' instead of ":" might result in a 58 ending up in your
+// result.
+//
+// Bools convert to "0" or "1".
+//
+// Floating point numbers are formatted with six-digit precision, which is
+// the default for "std::cout <<" or printf "%g" (the same as "%.6g").
+//
+//
+// You can convert to hexadecimal output rather than decimal output using the
+// `Hex` type contained here. To do so, pass `Hex(my_int)` as a parameter to
+// `StrCat()` or `StrAppend()`. You may specify a minimum hex field width using
+// a `PadSpec` enum.

+//
+// This header file contains functions for joining a range of elements and
+// returning the result as a std::string. StrJoin operations are specified by passing
+// a range, a separator std::string to use between the elements joined, and an
+// optional Formatter responsible for converting each argument in the range to a
+// std::string. If omitted, a default `AlphaNumFormatter()` is called on the elements
+// to be joined, using the same formatting that `absl::StrCat()` uses. This
+// package defines a number of default formatters, and you can define your own
+// implementations.
+//
+// Ranges are specified by passing a container with `std::begin()` and
+// `std::end()` iterators, container-specific `begin()` and `end()` iterators, a
+// brace-initialized `std::initializer_list`, or a `std::tuple` of heterogeneous
+// objects. The separator std::string is specified as an `absl::string_view`.
+//
+// Because the default formatter uses the `absl::AlphaNum` class,
+// `absl::StrJoin()`, like `absl::StrCat()`, will work out-of-the-box on
+// collections of strings, ints, floats, doubles, etc.
+//
+// Example:
+//
+// std::vector<std::string> v = {"foo", "bar", "baz"};
+// std::string s = absl::StrJoin(v, "-");
+// EXPECT_EQ("foo-bar-baz", s);
+//
+// See comments on the `absl::StrJoin()` function for more examples.

+// Concept: Formatter
+// -----------------------------------------------------------------------------
+//
+// A Formatter is a function object that is responsible for formatting its
+// argument as a std::string and appending it to a given output std::string. Formatters
+// may be implemented as function objects, lambdas, or normal functions. You may
+// provide your own Formatter to enable `absl::StrJoin()` to work with arbitrary
+// types.
+//
+// The following is an example of a custom Formatter that simply uses
+// `std::to_string()` to format an integer as a std::string.
+//
+// struct MyFormatter {
+// void operator()(std::string* out, int i) const {
+// out->append(std::to_string(i));
+// }
+// };
+//
+// You would use the above formatter by passing an instance of it as the final
+// argument to `absl::StrJoin()`:
+//
+// std::vector<int> v = {1, 2, 3, 4};
+// std::string s = absl::StrJoin(v, "-", MyFormatter());
+// EXPECT_EQ("1-2-3-4", s);
+//
+// The following standard formatters are provided within this file:
+//
+// - `AlphaNumFormatter()` (the default)
+// - `StreamFormatter()`
+// - `PairFormatter()`
+// - `DereferenceFormatter()`
+
+// AlphaNumFormatter()
+//
+// Default formatter used if none is specified. Uses `absl::AlphaNum` to convert
+// numeric arguments to strings.

+// StreamFormatter()
+//
+// Formats its argument using the << operator.
+inline strings_internal::StreamFormatterImpl StreamFormatter() {

+// StrJoin()
+// -----------------------------------------------------------------------------
+//
+// Joins a range of elements and returns the result as a std::string.
+// `absl::StrJoin()` takes a range, a separator std::string to use between the
+// elements joined, and an optional Formatter responsible for converting each
+// argument in the range to a std::string.
+//
+// If omitted, the default `AlphaNumFormatter()` is called on the elements to be
+// joined.
+//
+// Example 1:
+// // Joins a collection of strings. This pattern also works with a collection
+// // of `absl::string_view` or even `const char*`.
+// std::vector<std::string> v = {"foo", "bar", "baz"};
+// std::string s = absl::StrJoin(v, "-");
+// EXPECT_EQ("foo-bar-baz", s);
+//
+// Example 2:
+// // Joins the values in the given `std::initializer_list<>` specified using
+// // brace initialization. This pattern also works with an initializer_list
+// // of ints or `absl::string_view` -- any `AlphaNum`-compatible type.
+// std::string s = absl::StrJoin({"foo", "bar", "baz"}, "-");
+// EXPECT_EQ("foo-bar-baz", s);
+//
+// Example 3:
+// // Joins a collection of ints. This pattern also works with floats,
+// // doubles, int64s -- any `StrCat()`-compatible type.
+// std::vector<int> v = {1, 2, 3, -4};
+// std::string s = absl::StrJoin(v, "-");
+// EXPECT_EQ("1-2-3--4", s);
+//
+// Example 4:
+// // Joins a collection of pointer-to-int. By default, pointers are
+// // dereferenced and the pointee is formatted using the default format for
+// // that type; such dereferencing occurs for all levels of indirection, so
+// // this pattern works just as well for `std::vector<int**>` as for
+// // `std::vector<int*>`.
+// int x = 1, y = 2, z = 3;
+// std::vector<int*> v = {&x, &y, &z};
+// std::string s = absl::StrJoin(v, "-");
+// EXPECT_EQ("1-2-3", s);
+//
+// Example 5:
+// // Dereferencing of `std::unique_ptr<>` is also supported:
+// std::vector<std::unique_ptr<int>> v
+// v.emplace_back(new int(1));
+// v.emplace_back(new int(2));
+// v.emplace_back(new int(3));
+// std::string s = absl::StrJoin(v, "-");
+// EXPECT_EQ("1-2-3", s);
+//
+// Example 6:
+// // Joins a `std::map`, with each key-value pair separated by an equals
+// // sign. This pattern would also work with, say, a
+// // `std::vector<std::pair<>>`.
+// std::map<std::string, int> m = {
+// std::make_pair("a", 1),
+// std::make_pair("b", 2),
+// std::make_pair("c", 3)};
+// std::string s = absl::StrJoin(m, ",", absl::PairFormatter("="));
+// EXPECT_EQ("a=1,b=2,c=3", s);
+//
+// Example 7:
+// // These examples show how `absl::StrJoin()` handles a few common edge
+// // cases:
+// std::vector<std::string> v_empty;
+// EXPECT_EQ("", absl::StrJoin(v_empty, "-"));
+//
+// std::vector<std::string> v_one_item = {"foo"};
+// EXPECT_EQ("foo", absl::StrJoin(v_one_item, "-"));
+//
+// std::vector<std::string> v_empty_string = {""};
+// EXPECT_EQ("", absl::StrJoin(v_empty_string, "-"));
+//
+// std::vector<std::string> v_one_item_empty_string = {"a", ""};
+// EXPECT_EQ("a-", absl::StrJoin(v_one_item_empty_string, "-"));
+//
+// std::vector<std::string> v_two_empty_string = {"", ""};
+// EXPECT_EQ("-", absl::StrJoin(v_two_empty_string, "-"));
+//
+// Example 8:
+// // Joins a `std::tuple<T...>` of heterogeneous types, converting each to
+// // a std::string using the `absl::AlphaNum` class.
+// std::string s = absl::StrJoin(std::make_tuple(123, "abc", 0.456), "-");

+// This file defines `absl::StrReplaceAll()`, a general-purpose std::string
+// replacement function designed for large, arbitrary text substitutions,
+// especially on strings which you are receiving from some other system for
+// further processing (e.g. processing regular expressions, escaping HTML
+// entities, etc. `StrReplaceAll` is designed to be efficient even when only
+// one substitution is being performed, or when substitution is rare.
+//
+// If the std::string being modified is known at compile-time, and the substitutions
+// vary, `absl::Substitute()` may be a better choice.
+//
+// Example:
+//
+// std::string html_escaped = absl::StrReplaceAll(user_input, {
+// {"&", "&"},
+// {"<", "<"},
+// {">", ">"},
+// {"\"", """},

+// Delimiters
+//------------------------------------------------------------------------------
+//
+// `StrSplit()` uses delimiters to define the boundaries between elements in the
+// provided input. Several `Delimiter` types are defined below. If a std::string
+// (`const char*`, `std::string`, or `absl::string_view`) is passed in place of
+// an explicit `Delimiter` object, `StrSplit()` treats it the same way as if it
+// were passed a `ByString` delimiter.
+//
+// A `Delimiter` is an object with a `Find()` function that knows how to find
+// the first occurrence of itself in a given `absl::string_view`.
+//
+// The following `Delimiter` types are available for use within `StrSplit()`:
+//
+// - `ByString` (default for std::string arguments)
+// - `ByChar` (default for a char argument)
+// - `ByAnyChar`
+// - `ByLength`
+// - `MaxSplits`
+//
+//
+// A Delimiter's Find() member function will be passed the input text that is to
+// be split and the position to begin searching for the next delimiter in the
+// input text. The returned absl::string_view should refer to the next
+// occurrence (after pos) of the represented delimiter; this returned
+// absl::string_view represents the next location where the input std::string should
+// be broken. The returned absl::string_view may be zero-length if the Delimiter
+// does not represent a part of the std::string (e.g., a fixed-length delimiter). If
+// no delimiter is found in the given text, a zero-length absl::string_view
+// referring to text.end() should be returned (e.g.,
+// absl::string_view(text.end(), 0)). It is important that the returned
+// absl::string_view always be within the bounds of input text given as an
+// argument--it must not refer to a std::string that is physically located outside of
+// the given std::string.
+//
+// The following example is a simple Delimiter object that is created with a
+// single char and will look for that char in the text passed to the Find()
+// function:
+//
+// struct SimpleDelimiter {
+// const char c_;
+// explicit SimpleDelimiter(char c) : c_(c) {}
+// absl::string_view Find(absl::string_view text, size_t pos) {
+// auto found = text.find(c_, pos);
+// if (found == absl::string_view::npos)
+// return absl::string_view(text.end(), 0);
+//
+// return absl::string_view(text, found, 1);
+// }
+// };
+
+// ByString
+//
+// A sub-std::string delimiter. If `StrSplit()` is passed a std::string in place of a
+// `Delimiter` object, the std::string will be implicitly converted into a
+// `ByString` delimiter.
+//
+// Example:
+//
+// // Because a std::string literal is converted to an `absl::ByString`,
+// // the following two splits are equivalent.
+//
+// std::vector<std::string> v1 = absl::StrSplit("a, b, c", ", ");
+//
+// using absl::ByString;
+// std::vector<std::string> v2 = absl::StrSplit("a, b, c",
+// ByString(", "));
+// // v[0] == "a", v[1] == "b", v[2] == "c"
+class ByString {
+ public:
+ explicit ByString(absl::string_view sp);
+ absl::string_view Find(absl::string_view text, size_t pos) const;
+
+ private:
+ const std::string delimiter_;
+};
+
+// ByChar
+//
+// A single character delimiter. `ByChar` is functionally equivalent to a
+// 1-char std::string within a `ByString` delimiter, but slightly more
+// efficient.
+//
+// Example:
+//
+// // Because a char literal is converted to a absl::ByChar,
+// // the following two splits are equivalent.
+// std::vector<std::string> v1 = absl::StrSplit("a,b,c", ',');
+// using absl::ByChar;
+// std::vector<std::string> v2 = absl::StrSplit("a,b,c", ByChar(','));
+// // v[0] == "a", v[1] == "b", v[2] == "c"
+//
+// `ByChar` is also the default delimiter if a single character is given
+// as the delimiter to `StrSplit()`. For example, the following calls are
+// equivalent:
+//
+// std::vector<std::string> v = absl::StrSplit("a-b", '-');
+//
+// using absl::ByChar;
+// std::vector<std::string> v = absl::StrSplit("a-b", ByChar('-'));

+

+//
+// A delimiter that will match any of the given byte-sized characters within
+// its provided std::string.
+//
+// Note: this delimiter works with single-byte std::string data, but does not work
+// with variable-width encodings, such as UTF-8.
+//
+// Example:
+//
+// using absl::ByAnyChar;
+// std::vector<std::string> v = absl::StrSplit("a,b=c", ByAnyChar(",="));
+// // v[0] == "a", v[1] == "b", v[2] == "c"

+//------------------------------------------------------------------------------
+// Predicates
+//------------------------------------------------------------------------------
+//
+// Predicates filter the results of a `StrSplit()` by determining whether or not
+// a resultant element is included in the result set. A predicate may be passed
+// as an optional third argument to the `StrSplit()` function.
+//
+// Predicates are unary functions (or functors) that take a single
+// `absl::string_view` argument and return a bool indicating whether the
+// argument should be included (`true`) or excluded (`false`).
+//
+// Predicates are useful when filtering out empty substrings. By default, empty
+// substrings may be returned by `StrSplit()`, which is similar to the way split
+// functions work in other programming languages.
+
+// AllowEmpty()
+//
+// Always returns `true`, indicating that all strings--including empty
+// strings--should be included in the split output. This predicate is not
+// strictly needed because this is the default behavior of `StrSplit()`;
+// however, it might be useful at some call sites to make the intent explicit.
+//
+// Example:
+//
+// std::vector<std::string> v = absl::StrSplit(" a , ,,b,", ',', AllowEmpty());
+//
+// // v[0] == " a ", v[1] == " ", v[2] == "", v[3] = "b", v[4] == ""
+struct AllowEmpty {
+ bool operator()(absl::string_view) const { return true; }
+};
+
+// SkipEmpty()
+//
+// Returns `false` if the given `absl::string_view` is empty, indicating that
+// `StrSplit()` should omit the empty std::string.
+//
+// Example:
+//
+// std::vector<std::string> v = absl::StrSplit(",a,,b,", ',', SkipEmpty());
+//
+// // v[0] == "a", v[1] == "b"
+//
+// Note: `SkipEmpty()` does not consider a std::string containing only whitespace
+// to be empty. To skip such whitespace as well, use the `SkipWhitespace()`
+// predicate.
+struct SkipEmpty {
+ bool operator()(absl::string_view sp) const { return !sp.empty(); }
+};
+
+// SkipWhitespace()
+//
+// Returns `false` if the given `absl::string_view` is empty *or* contains only
+// whitespace, indicating that `StrSplit()` should omit the std::string.
+//
+// Example:
+//
+// std::vector<std::string> v = absl::StrSplit(" a , ,,b,",
+// ',', SkipWhitespace());
+// // v[0] == " a ", v[1] == "b"
+//
+// // SkipEmpty() would return whitespace elements
+// std::vector<std::string> v = absl::StrSplit(" a , ,,b,", ',', SkipEmpty());
+// // v[0] == " a ", v[1] == " ", v[2] == "b"
+struct SkipWhitespace {
+ bool operator()(absl::string_view sp) const {
+ sp = absl::StripAsciiWhitespace(sp);
+ return !sp.empty();
+ }
+};
+
+//------------------------------------------------------------------------------
+// StrSplit()
+//------------------------------------------------------------------------------
+
+// StrSplit()
+//
+// Splits a given `std::string` based on the provided `Delimiter` object,
+// returning the elements within the type specified by the caller. Optionally,
+// you may also pass a `Predicate` to `StrSplit()` indicating whether to include
+// or exclude the resulting element within the final result set. (See the
+// overviews for Delimiters and Predicates above.)
+//
+// Example:
+//
+// std::vector<std::string> v = absl::StrSplit("a,b,c,d", ',');
+// // v[0] == "a", v[1] == "b", v[2] == "c", v[3] == "d"
+//
+// You can also provide an explicit `Delimiter` object:
+//
+// Example:
+//
+// using absl::ByAnyChar;
+// std::vector<std::string> v = absl::StrSplit("a,b=c", ByAnyChar(",="));
+// // v[0] == "a", v[1] == "b", v[2] == "c"
+//
+// See above for more information on delimiters.
+//
+// By default, empty strings are included in the result set. You can optionally
+// include a third `Predicate` argument to apply a test for whether the
+// resultant element should be included in the result set:
+//
+// Example:
+//
+// std::vector<std::string> v = absl::StrSplit(" a , ,,b,",
+// ',', SkipWhitespace());
+// // v[0] == " a ", v[1] == "b"
+//
+// See above for more information on predicates.
+//
+//------------------------------------------------------------------------------
+// StrSplit() Return Types
+//------------------------------------------------------------------------------
+//
+// The `StrSplit()` function adapts the returned collection to the collection
+// specified by the caller (e.g. `std::vector` above). The returned collections
+// may contain `string`, `absl::string_view` (in which case the original std::string
+// being split must ensure that it outlives the collection), or any object that
+// can be explicitly created from an `absl::string_view`. This behavior works
+// for:
+//
+// 1) All standard STL containers including `std::vector`, `std::list`,
+// `std::deque`, `std::set`,`std::multiset`, 'std::map`, and `std::multimap`
+// 2) `std::pair` (which is not actually a container). See below.
+//
+// Example:
+//
+// // The results are returned as `absl::string_view` objects. Note that we
+// // have to ensure that the input std::string outlives any results.
+// std::vector<absl::string_view> v = absl::StrSplit("a,b,c", ',');
+//

+// // Stores results in a map. The map implementation assumes that the input
+// // is provided as a series of key/value pairs. For example, the 0th element
+// // resulting from the split will be stored as a key to the 1st element. If
+// // an odd number of elements are resolved, the last element is paired with
+// // a default-constructed value (e.g., empty std::string).
+// std::map<std::string, std::string> m = absl::StrSplit("a,b,c", ',');
+// // m["a"] == "b", m["c"] == "" // last component value equals ""
+//
+// Splitting to `std::pair` is an interesting case because it can hold only two
+// elements and is not a collection type. When splitting to a `std::pair` the
+// first two split strings become the `std::pair` `.first` and `.second`
+// members, respectively. The remaining split substrings are discarded. If there
+// are less than two split substrings, the empty std::string is used for the
+// corresponding
+// `std::pair` member.
+//
+// Example:
+//
+// // Stores first two split strings as the members in a std::pair.
+// std::pair<std::string, std::string> p = absl::StrSplit("a,b,c", ',');
+// // p.first == "a", p.second == "b" // "c" is omitted.
+//
+// The `StrSplit()` function can be used multiple times to perform more
+// complicated splitting logic, such as intelligently parsing key-value pairs.
+//
+// Example:
+//
+// // The input std::string "a=b=c,d=e,f=,g" becomes
+// // { "a" => "b=c", "d" => "e", "f" => "", "g" => "" }
+// std::map<std::string, std::string> m;
+// for (absl::string_view sp : absl::StrSplit("a=b=c,d=e,f=,g", ',')) {
+// m.insert(absl::StrSplit(sp, absl::MaxSplits('=', 1)));
+// }
+// EXPECT_EQ("b=c", m.find("a")->second);
+// EXPECT_EQ("e", m.find("d")->second);
+// EXPECT_EQ("", m.find("f")->second);
+// EXPECT_EQ("", m.find("g")->second);
+//
+// WARNING: Due to a legacy bug that is maintained for backward compatibility,
+// splitting the following empty string_views produces different results:
+//
+// absl::StrSplit(absl::string_view(""), '-'); // {""}
+// absl::StrSplit(absl::string_view(), '-'); // {}, but should be {""}
+//
+// Try not to depend on this distinction because the bug may one day be fixed.

+// `std::string`, or another `absl::string_view` argument with no need to copy
+// the std::string data. Systematic use of `string_view` within function arguments
+// reduces data copies and `strlen()` calls.
+//
+// Because of its small size, prefer passing `string_view` by value:
+//
+// void MyFunction(absl::string_view arg);
+//
+// If circumstances require, you may also pass one by const reference:
+//
+// void MyFunction(const absl::string_view& arg); // not preferred
+//
+// Passing by value generates slightly smaller code for many architectures.
+//
+// In either case, the source data of the `string_view` must outlive the
+// `string_view` itself.
+//
+// A `string_view` is also suitable for local variables if you know that the
+// lifetime of the underlying object is longer than the lifetime of your
+// `string_view` variable. However, beware of binding a `string_view` to a
+// temporary value:
+//
+// // BAD use of string_view: lifetime problem
+// absl::string_view sv = obj.ReturnAString();
+//
+// // GOOD use of string_view: str outlives sv
+// std::string str = obj.ReturnAString();
+// absl::string_view sv = str;
+//
+// Due to lifetime issues, a `string_view` is sometimes a poor choice for a
+// return value and usually a poor choice for a data member. If you do use a
+// `string_view` this way, it is your responsibility to ensure that the object
+// pointed to by the `string_view` outlives the `string_view`.
+//
+// A `string_view` may represent a whole std::string or just part of a std::string. For
+// example, when splitting a std::string, `std::vector<absl::string_view>` is a
+// natural data type for the output.
+//
+//
+// When constructed from a source which is nul-terminated, the `string_view`
+// itself will not include the nul-terminator unless a specific size (including
+// the nul) is passed to the constructor. As a result, common idioms that work
+// on nul-terminated strings do not work on `string_view` objects. If you write
+// code that scans a `string_view`, you must check its length rather than test
+// for nul, for example. Note, however, that nuls may still be embedded within
+// a `string_view` explicitly.
+//
+// You may create a null `string_view` in two ways:
+//
+// absl::string_view sv();
+// absl::string_view sv(nullptr, 0);
+//
+// For the above, `sv.data() == nullptr`, `sv.length() == 0`, and
+// `sv.empty() == true`. Also, if you create a `string_view` with a non-null
+// pointer then `sv.data() != nullptr`. Thus, you can use `string_view()` to
+// signal an undefined value that is different from other `string_view` values
+// in a similar fashion to how `const char* p1 = nullptr;` is different from
+// `const char* p2 = "";`. However, in practice, it is not recommended to rely
+// on this behavior.
+//
+// Be careful not to confuse a null `string_view` with an empty one. A null
+// `string_view` is an empty `string_view`, but some empty `string_view`s are
+// not null. Prefer checking for emptiness over checking for null.
+//
+// There are many ways to create an empty string_view:
+//
+// const char* nullcp = nullptr;
+// // string_view.size() will return 0 in all cases.
+// absl::string_view();
+// absl::string_view(nullcp, 0);
+// absl::string_view("");
+// absl::string_view("", 0);
+// absl::string_view("abcdef", 0);
+// absl::string_view("abcdef" + 6, 0);
+//
+// All empty `string_view` objects whether null or not, are equal:
+//
+// absl::string_view() == absl::string_view("", 0)
+// absl::string_view(nullptr, 0) == absl:: string_view("abcdef"+6, 0)

+//
+// This package contains functions for efficiently performing std::string
+// substitutions using a format std::string with positional notation:
+// `Substitute()` and `SubstituteAndAppend()`.
+//
+// Unlike printf-style format specifiers, `Substitute()` functions do not need
+// to specify the type of the substitution arguments. Supported arguments
+// following the format std::string, such as strings, string_views, ints,
+// floats, and bools, are automatically converted to strings during the
+// substitution process. (See below for a full list of supported types.)
+//
+// `Substitute()` does not allow you to specify *how* to format a value, beyond
+// the default conversion to std::string. For example, you cannot format an integer
+// in hex.
+//
+// The format std::string uses positional identifiers indicated by a dollar sign ($)
+// and single digit positional ids to indicate which substitution arguments to
+// use at that location within the format std::string.
+//
+// Example 1:
+// std::string s = Substitute("$1 purchased $0 $2. Thanks $1!",
+// 5, "Bob", "Apples");
+// EXPECT_EQ("Bob purchased 5 Apples. Thanks Bob!", s);
+//
+// Example 2:
+// std::string s = "Hi. ";
+// SubstituteAndAppend(&s, "My name is $0 and I am $1 years old.", "Bob", 5);
+// EXPECT_EQ("Hi. My name is Bob and I am 5 years old.", s);
+//
+//
+// Supported types:
+// * absl::string_view, std::string, const char* (null is equivalent to "")
+// * int32_t, int64_t, uint32_t, uint64
+// * float, double
+// * bool (Printed as "true" or "false")
+// * pointer types other than char* (Printed as "0x<lower case hex std::string>",
+// except that null is printed as "NULL")
+//
+// If an invalid format std::string is provided, Substitute returns an empty std::string
+// and SubstituteAndAppend does not change the provided output std::string.
+// A format std::string is invalid if it:
+// * ends in an unescaped $ character,
+// e.g. "Hello $", or
+// * calls for a position argument which is not provided,
+// e.g. Substitute("Hello $2", "world"), or
+// * specifies a non-digit, non-$ character after an unescaped $ character,
+// e.g. "Hello $f".
+// In debug mode, i.e. #ifndef NDEBUG, such errors terminate the program.

+// BlockingCounter
+//
+// This class allows a thread to block for a pre-specified number of actions.
+// `BlockingCounter` maintains a single non-negative abstract integer "count"
+// with an initial value `initial_count`. A thread can then call `Wait()` on
+// this blocking counter to block until the specified number of events occur;
+// worker threads then call 'DecrementCount()` on the counter upon completion of
+// their work. Once the counter's internal "count" reaches zero, the blocked
+// thread unblocks.
+//
+// A `BlockingCounter` requires the following:
+// - its `initial_count` is non-negative.
+// - the number of calls to `DecrementCount()` on it is at most
+// `initial_count`.
+// - `Wait()` is called at most once on it.
+//
+// Given the above requirements, a `BlockingCounter` provides the following
+// guarantees:
+// - Once its internal "count" reaches zero, no legal action on the object
+// can further change the value of "count".
+// - When `Wait()` returns, it is legal to destroy the `BlockingCounter`.
+// - When `Wait()` returns, the number of calls to `DecrementCount()` on
+// this blocking counter exactly equals `initial_count`.
+//
+// Example:
+// BlockingCounter bcount(N); // there are N items of work
+// ... Allow worker threads to start.
+// ... On completing each work item, workers do:
+// ... bcount.DecrementCount(); // an item of work has been completed
+//
+// bcount.Wait(); // wait for all work to be complete
+//

+// constructor is called.
+//
+// Objects constructed with the default constructor are constructed and
+// destructed like any other object, and should never be allocated in
+// static storage.
+//
+// Objects constructed with the LinkerInitialized constructor should
+// always be in static storage. For such objects, calls to get() are always
+// valid, except from signal handlers.
+//
+// Note that this implementation relies on undefined language behavior that
+// are known to hold for the set of supported compilers. An analysis
+// follows.
+//
+// From the C++11 standard:
+//
+// [basic.life] says an object has non-trivial initialization if it is of
+// class type and it is initialized by a constructor other than a trivial
+// default constructor. (the LinkerInitialized constructor is
+// non-trivial)
+//
+// [basic.life] says the lifetime of an object with a non-trivial
+// constructor begins when the call to the constructor is complete.
+//
+// [basic.life] says the lifetime of an object with non-trivial destructor
+// ends when the call to the destructor begins.
+//
+// [basic.life] p5 specifies undefined behavior when accessing non-static
+// members of an instance outside its
+// lifetime. (SynchronizationStorage::get() access non-static members)
+//
+// So, LinkerInitialized object of SynchronizationStorage uses a
+// non-trivial constructor, which is called at some point during dynamic
+// initialization, and is therefore subject to order of dynamic
+// initialization bugs, where get() is called before the object's
+// constructor is, resulting in undefined behavior.
+//
+// Similarly, a LinkerInitialized SynchronizationStorage object has a
+// non-trivial destructor, and so its lifetime ends at some point during
+// destruction of objects with static storage duration [basic.start.term]
+// p4. There is a window where other exit code could call get() after this
+// occurs, resulting in undefined behavior.
+//
+// Combined, these statements imply that LinkerInitialized instances
+// of SynchronizationStorage<T> rely on undefined behavior.
+//
+// However, in practice, the implementation works on all supported
+// compilers. Specifically, we rely on:
+//
+// a) zero-initialization being sufficient to initialize
+// LinkerInitialized instances for the purposes of calling
+// get(), regardless of when the constructor is called. This is
+// because the is_dynamic_ boolean is correctly zero-initialized to
+// false.
+//
+// b) the LinkerInitialized constructor is a NOP, and immaterial to
+// even to concurrent calls to get().
+//
+// c) the destructor being a NOP for LinkerInitialized objects
+// (guaranteed by a check for !is_dynamic_), and so any concurrent and
+// subsequent calls to get() functioning as if the destructor were not
+// called, by virtue of the instances' storage remaining valid after the
+// destructor runs.
+//
+// d) That a-c apply transitively when SynchronizationStorage<T> is the
+// only member of a class allocated in static storage.
+//
+// Nothing in the language standard guarantees that a-d hold. In practice,
+// these hold in all supported compilers.
+//
+// Future direction:
+//
+// Ideally, we would simply use std::mutex or a similar class, which when
+// allocated statically would support use immediately after static
+// initialization up until static storage is reclaimed (i.e. the properties
+// we require of all "linker initialized" instances).
+//
+// Regarding construction in static storage, std::mutex is required to
+// provide a constexpr default constructor [thread.mutex.class], which
+// ensures the instance's lifetime begins with static initialization
+// [basic.start.init], and so is immune to any problems caused by the order
+// of dynamic initialization. However, as of this writing Microsoft's
+// Visual Studio does not provide a constexpr constructor for std::mutex.
+// See
+// https://blogs.msdn.microsoft.com/vcblog/2015/06/02/constexpr-complete-for-vs-2015-rtm-c11-compiler-c17-stl/
+//
+// Regarding destruction of instances in static storage, [basic.life] does
+// say an object ends when storage in which the occupies is released, in
+// the case of non-trivial destructor. However, std::mutex is not specified
+// to have a trivial destructor.
+//
+// So, we would need a class with a constexpr default constructor and a
+// trivial destructor. Today, we can achieve neither desired property using
+// std::mutex directly.

+//
+// This header file defines a `Mutex` -- a mutually exclusive lock -- and the
+// most common type of synchronization primitive for facilitating locks on
+// shared resources. A mutex is used to prevent multiple threads from accessing
+// and/or writing to a shared resource concurrently.
+//
+// Unlike a `std::mutex`, the Abseil `Mutex` provides the following additional
+// features:
+// * Conditional predicates intrinsic to the `Mutex` object
+// * Reader/writer locks, in addition to standard exclusive/writer locks
+// * Deadlock detection and debug support.
+//
+// The following helper classes are also defined within this file:
+//
+// MutexLock - An RAII wrapper to acquire and release a `Mutex` for exclusive/
+// write access within the current scope.
+// ReaderMutexLock
+// - An RAII wrapper to acquire and release a `Mutex` for shared/read
+// access within the current scope.
+//
+// WriterMutexLock
+// - Alias for `MutexLock` above, designed for use in distinguishing
+// reader and writer locks within code.
+//
+// In addition to simple mutex locks, this file also defines ways to perform
+// locking under certain conditions.
+//
+// Condition - (Preferred) Used to wait for a particular predicate that
+// depends on state protected by the `Mutex` to become true.
+// CondVar - A lower-level variant of `Condition` that relies on
+// application code to explicitly signal the `CondVar` when
+// a condition has been met.
+//
+// See below for more information on using `Condition` or `CondVar`.
+//
+// Mutexes and mutex behavior can be quite complicated. The information within
+// this header file is limited, as a result. Please consult the Mutex guide for
+// more complete information and examples.

+// Mutex
+// -----------------------------------------------------------------------------
+//
+// A `Mutex` is a non-reentrant (aka non-recursive) Mutually Exclusive lock
+// on some resource, typically a variable or data structure with associated
+// invariants. Proper usage of mutexes prevents concurrent access by different
+// threads to the same resource.
+//
+// A `Mutex` has two basic operations: `Mutex::Lock()` and `Mutex::Unlock()`.
+// The `Lock()` operation *acquires* a `Mutex` (in a state known as an
+// *exclusive* -- or write -- lock), while the `Unlock()` operation *releases* a
+// Mutex. During the span of time between the Lock() and Unlock() operations,
+// a mutex is said to be *held*. By design all mutexes support exclusive/write
+// locks, as this is the most common way to use a mutex.
+//
+// The `Mutex` state machine for basic lock/unlock operations is quite simple:
+//
+// | | Lock() | Unlock() |
+// |----------------+------------+----------|
+// | Free | Exclusive | invalid |
+// | Exclusive | blocks | Free |
+//
+// Attempts to `Unlock()` must originate from the thread that performed the
+// corresponding `Lock()` operation.
+//
+// An "invalid" operation is disallowed by the API. The `Mutex` implementation
+// is allowed to do anything on an invalid call, including but not limited to
+// crashing with a useful error message, silently succeeding, or corrupting
+// data structures. In debug mode, the implementation attempts to crash with a
+// useful error message.
+//
+// `Mutex` is not guaranteed to be "fair" in prioritizing waiting threads; it
+// is, however, approximately fair over long periods, and starvation-free for
+// threads at the same priority.
+//
+// The lock/unlock primitives are now annotated with lock annotations
+// defined in (base/thread_annotations.h). When writing multi-threaded code,
+// you should use lock annotations whenever possible to document your lock
+// synchronization policy. Besides acting as documentation, these annotations
+// also help compilers or static analysis tools to identify and warn about
+// issues that could potentially result in race conditions and deadlocks.
+//
+// For more information about the lock annotations, please see
+// [Thread Safety Analysis](http://clang.llvm.org/docs/ThreadSafetyAnalysis.html)
+// in the Clang documentation.
+//
+// See also `MutexLock`, below, for scoped `Mutex` acquisition.

+
+ // Conditional usage of a `Mutex` can occur using two distinct paradigms:
+ //
+ // * Use of `Mutex` member functions with `Condition` objects.
+ // * Use of the separate `CondVar` abstraction.
+ //
+ // In general, prefer use of `Condition` and the `Mutex` member functions
+ // listed below over `CondVar`. When there are multiple threads waiting on
+ // distinctly different conditions, however, a battery of `CondVar`s may be
+ // more efficient. This section discusses use of `Condition` objects.
+ //
+ // `Mutex` contains member functions for performing lock operations only under
+ // certain conditions, of class `Condition`. For correctness, the `Condition`
+ // must return a boolean that is a pure function, only of state protected by
+ // the `Mutex`. The condition must be invariant w.r.t. environmental state
+ // such as thread, cpu id, or time, and must be `noexcept`. The condition will
+ // always be invoked with the mutex held in at least read mode, so you should
+ // not block it for long periods or sleep it on a timer.
+ //
+ // Since a condition must not depend directly on the current time, use
+ // `*WithTimeout()` member function variants to make your condition
+ // effectively true after a given duration, or `*WithDeadline()` variants to
+ // make your condition effectively true after a given time.
+ //
+ // The condition function should have no side-effects aside from debug
+ // logging; as a special exception, the function may acquire other mutexes
+ // provided it releases all those that it acquires. (This exception was
+ // required to allow logging.)

+// Condition
+// -----------------------------------------------------------------------------
+//
+// As noted above, `Mutex` contains a number of member functions which take a
+// `Condition` as a argument; clients can wait for conditions to become `true`
+// before attempting to acquire the mutex. These sections are known as
+// "condition critical" sections. To use a `Condition`, you simply need to
+// construct it, and use within an appropriate `Mutex` member function;
+// everything else in the `Condition` class is an implementation detail.
+//
+// A `Condition` is specified as a function pointer which returns a boolean.
+// `Condition` functions should be pure functions -- their results should depend
+// only on passed arguments, should not consult any external state (such as
+// clocks), and should have no side-effects, aside from debug logging. Any
+// objects that the function may access should be limited to those which are
+// constant while the mutex is blocked on the condition (e.g. a stack variable),
+// or objects of state protected explicitly by the mutex.
+//
+// No matter which construction is used for `Condition`, the underlying
+// function pointer / functor / callable must not throw any
+// exceptions. Correctness of `Mutex` / `Condition` is not guaranteed in
+// the face of a throwing `Condition`. (When Abseil is allowed to depend
+// on C++17, these function pointers will be explicitly marked
+// `noexcept`; until then this requirement cannot be enforced in the
+// type system.)
+//
+// Note: to use a `Condition`, you need only construct it and pass it within the
+// appropriate `Mutex' member function, such as `Mutex::Await()`.
+//
+// Example:
+//
+// // assume count_ is not internal reference count
+// int count_ GUARDED_BY(mu_);
+//
+// mu_.LockWhen(Condition(+[](int* count) { return *count == 0; },
+// &count_));
+//
+// When multiple threads are waiting on exactly the same condition, make sure
+// that they are constructed with the same parameters (same pointer to function
+// + arg, or same pointer to object + method), so that the mutex implementation
+// can avoid redundantly evaluating the same condition for each thread.

+// notification.h
+// -----------------------------------------------------------------------------
+//
+// This header file defines a `Notification` abstraction, which allows threads
+// to receive notification of a single occurrence of a single event.
+//
+// The `Notification` object maintains a private boolean "notified" state that
+// transitions to `true` at most once. The `Notification` class provides the
+// following primary member functions:
+// * `HasBeenNotified() `to query its state
+// * `WaitForNotification*()` to have threads wait until the "notified" state
+// is `true`.
+// * `Notify()` to set the notification's "notified" state to `true` and
+// notify all waiting threads that the event has occurred.
+// This method may only be called once.
+//
+// Note that while `Notify()` may only be called once, it is perfectly valid to
+// call any of the `WaitForNotification*()` methods multiple times, from
+// multiple threads -- even after the notification's "notified" state has been
+// set -- in which case those methods will immediately return.
+//
+// Note that the lifetime of a `Notification` requires careful consideration;
+// it might not be safe to destroy a notification after calling `Notify()` since
+// it is still legal for other threads to call `WaitForNotification*()` methods
+// on the notification. However, observers responding to a "notified" state of
+// `true` can safely delete the notification without interfering with the call
+// to `Notify()` in the other thread.
+//
+// Memory ordering: For any threads X and Y, if X calls `Notify()`, then any
+// action taken by X before it calls `Notify()` is visible to thread Y after:
+// * Y returns from `WaitForNotification()`, or
+// * Y receives a `true` return value from either `HasBeenNotified()` or
+// `WaitForNotificationWithTimeout()`.

+// the same point as the end of the last, but may have a different slope (that
+// is, a different idea of the cycle counter frequency). Every couple of
+// seconds, the kernel time source is sampled and compared with the current
+// approximation. A new slope is chosen that, if followed for another couple
+// of seconds, will correct the error at the current position. The information
+// for a sample is in the "last_sample" struct. The linear approximation is
+// estimated_time = last_sample.base_ns +
+// last_sample.ns_per_cycle * (counter_reading - last_sample.base_cycles)
+// (ns_per_cycle is actually stored in different units and scaled, to avoid
+// overflow). The base_ns of the next linear approximation is the
+// estimated_time using the last approximation; the base_cycles is the cycle
+// counter value at that time; the ns_per_cycle is the number of ns per cycle
+// measured since the last sample, but adjusted so that most of the difference
+// between the estimated_time and the kernel time will be corrected by the
+// estimated time to the next sample. In normal operation, this algorithm
+// relies on:
+// - the cycle counter and kernel time rates not changing a lot in a few
+// seconds.
+// - the client calling into the code often compared to a couple of seconds, so
+// the time to the next correction can be estimated.
+// Any time ns_per_cycle is not known, a major error is detected, or the

+// The implementation of the absl::Duration class, which is declared in
+// //absl/time.h. This class behaves like a numeric type; it has no public
+// methods and is used only through the operators defined here.
+//
+// Implementation notes:
+//
+// An absl::Duration is represented as
+//
+// rep_hi_ : (int64_t) Whole seconds
+// rep_lo_ : (uint32_t) Fractions of a second
+//
+// The seconds value (rep_hi_) may be positive or negative as appropriate.
+// The fractional seconds (rep_lo_) is always a positive offset from rep_hi_.
+// The API for Duration guarantees at least nanosecond resolution, which
+// means rep_lo_ could have a max value of 1B - 1 if it stored nanoseconds.
+// However, to utilize more of the available 32 bits of space in rep_lo_,
+// we instead store quarters of a nanosecond in rep_lo_ resulting in a max
+// value of 4B - 1. This allows us to correctly handle calculations like
+// 0.5 nanos + 0.5 nanos = 1 nano. The following example shows the actual
+// Duration rep using quarters of a nanosecond.
+//
+// 2.5 sec = {rep_hi_=2, rep_lo_=2000000000} // lo = 4 * 500000000
+// -2.5 sec = {rep_hi_=-3, rep_lo_=2000000000}
+//
+// Infinite durations are represented as Durations with the rep_lo_ field set
+// to all 1s.
+//
+// +InfiniteDuration:
+// rep_hi_ : kint64max
+// rep_lo_ : ~0U
+//
+// -InfiniteDuration:
+// rep_hi_ : kint64min
+// rep_lo_ : ~0U
+//

+namespace absl {
+namespace time_internal {
+namespace cctz {
+
+// The term "civil time" refers to the legally recognized human-scale time
+// that is represented by the six fields YYYY-MM-DD hh:mm:ss. Modern-day civil
+// time follows the Gregorian Calendar and is a time-zone-independent concept.
+// A "date" is perhaps the most common example of a civil time (represented in
+// this library as cctz::civil_day). This library provides six classes and a
+// handful of functions that help with rounding, iterating, and arithmetic on
+// civil times while avoiding complications like daylight-saving time (DST).
+//
+// The following six classes form the core of this civil-time library:
+//
+// * civil_second
+// * civil_minute
+// * civil_hour
+// * civil_day
+// * civil_month
+// * civil_year
+//
+// Each class is a simple value type with the same interface for construction
+// and the same six accessors for each of the civil fields (year, month, day,
+// hour, minute, and second, aka YMDHMS). These classes differ only in their
+// alignment, which is indicated by the type name and specifies the field on
+// which arithmetic operates.
+//
+// Each class can be constructed by passing up to six optional integer
+// arguments representing the YMDHMS fields (in that order) to the
+// constructor. Omitted fields are assigned their minimum valid value. Hours,
+// minutes, and seconds will be set to 0, month and day will be set to 1, and
+// since there is no minimum valid year, it will be set to 1970. So, a
+// default-constructed civil-time object will have YMDHMS fields representing
+// "1970-01-01 00:00:00". Fields that are out-of-range are normalized (e.g.,
+// October 32 -> November 1) so that all civil-time objects represent valid
+// values.
+//
+// Each civil-time class is aligned to the civil-time field indicated in the
+// class's name after normalization. Alignment is performed by setting all the
+// inferior fields to their minimum valid value (as described above). The
+// following are examples of how each of the six types would align the fields
+// representing November 22, 2015 at 12:34:56 in the afternoon. (Note: the
+// std::string format used here is not important; it's just a shorthand way of
+// showing the six YMDHMS fields.)
+//
+// civil_second 2015-11-22 12:34:56
+// civil_minute 2015-11-22 12:34:00
+// civil_hour 2015-11-22 12:00:00
+// civil_day 2015-11-22 00:00:00
+// civil_month 2015-11-01 00:00:00
+// civil_year 2015-01-01 00:00:00
+//
+// Each civil-time type performs arithmetic on the field to which it is
+// aligned. This means that adding 1 to a civil_day increments the day field
+// (normalizing as necessary), and subtracting 7 from a civil_month operates
+// on the month field (normalizing as necessary). All arithmetic produces a
+// valid civil time. Difference requires two similarly aligned civil-time
+// objects and returns the scalar answer in units of the objects' alignment.
+// For example, the difference between two civil_hour objects will give an
+// answer in units of civil hours.
+//
+// In addition to the six civil-time types just described, there are
+// a handful of helper functions and algorithms for performing common
+// calculations. These are described below.
+//
+// Note: In C++14 and later, this library is usable in a constexpr context.
+//
+// CONSTRUCTION:
+//
+// Each of the civil-time types can be constructed in two ways: by directly
+// passing to the constructor up to six (optional) integers representing the
+// YMDHMS fields, or by copying the YMDHMS fields from a differently aligned
+// civil-time type.
+//
+// civil_day default_value; // 1970-01-01 00:00:00
+//
+// civil_day a(2015, 2, 3); // 2015-02-03 00:00:00
+// civil_day b(2015, 2, 3, 4, 5, 6); // 2015-02-03 00:00:00
+// civil_day c(2015); // 2015-01-01 00:00:00
+//
+// civil_second ss(2015, 2, 3, 4, 5, 6); // 2015-02-03 04:05:06
+// civil_minute mm(ss); // 2015-02-03 04:05:00
+// civil_hour hh(mm); // 2015-02-03 04:00:00
+// civil_day d(hh); // 2015-02-03 00:00:00
+// civil_month m(d); // 2015-02-01 00:00:00
+// civil_year y(m); // 2015-01-01 00:00:00
+//
+// m = civil_month(y); // 2015-01-01 00:00:00
+// d = civil_day(m); // 2015-01-01 00:00:00
+// hh = civil_hour(d); // 2015-01-01 00:00:00
+// mm = civil_minute(hh); // 2015-01-01 00:00:00
+// ss = civil_second(mm); // 2015-01-01 00:00:00
+//
+// ALIGNMENT CONVERSION:
+//
+// The alignment of a civil-time object cannot change, but the object may be
+// used to construct a new object with a different alignment. This is referred
+// to as "realigning". When realigning to a type with the same or more
+// precision (e.g., civil_day -> civil_second), the conversion may be
+// performed implicitly since no information is lost. However, if information
+// could be discarded (e.g., civil_second -> civil_day), the conversion must
+// be explicit at the call site.
+//
+// void fun(const civil_day& day);
+//
+// civil_second cs;
+// fun(cs); // Won't compile because data may be discarded
+// fun(civil_day(cs)); // OK: explicit conversion
+//
+// civil_day cd;
+// fun(cd); // OK: no conversion needed
+//
+// civil_month cm;
+// fun(cm); // OK: implicit conversion to civil_day
+//
+// NORMALIZATION:
+//
+// Integer arguments passed to the constructor may be out-of-range, in which
+// case they are normalized to produce a valid civil-time object. This enables
+// natural arithmetic on constructor arguments without worrying about the
+// field's range. Normalization guarantees that there are no invalid
+// civil-time objects.
+//
+// civil_day d(2016, 10, 32); // Out-of-range day; normalized to 2016-11-01
+//
+// Note: If normalization is undesired, you can signal an error by comparing
+// the constructor arguments to the normalized values returned by the YMDHMS
+// properties.
+//
+// PROPERTIES:
+//
+// All civil-time types have accessors for all six of the civil-time fields:
+// year, month, day, hour, minute, and second. Recall that fields inferior to
+// the type's aligment will be set to their minimum valid value.
+//
+// civil_day d(2015, 6, 28);
+// // d.year() == 2015
+// // d.month() == 6
+// // d.day() == 28
+// // d.hour() == 0
+// // d.minute() == 0
+// // d.second() == 0
+//
+// COMPARISON:
+//
+// Comparison always considers all six YMDHMS fields, regardless of the type's
+// alignment. Comparison between differently aligned civil-time types is
+// allowed.
+//
+// civil_day feb_3(2015, 2, 3); // 2015-02-03 00:00:00
+// civil_day mar_4(2015, 3, 4); // 2015-03-04 00:00:00
+// // feb_3 < mar_4
+// // civil_year(feb_3) == civil_year(mar_4)
+//
+// civil_second feb_3_noon(2015, 2, 3, 12, 0, 0); // 2015-02-03 12:00:00
+// // feb_3 < feb_3_noon

+// for (civil_day d(2015, 2, 1); d < civil_month(2015, 3); ++d) {
+// // ...
+// }
+//
+// STREAMING:
+//
+// Each civil-time type may be sent to an output stream using operator<<().
+// The output format follows the pattern "YYYY-MM-DDThh:mm:ss" where fields
+// inferior to the type's alignment are omitted.
+//
+// civil_second cs(2015, 2, 3, 4, 5, 6);

+// std::cout << cd << "\n"; // Outputs: 2015-02-03
+//
+// civil_year cy(cs);
+// std::cout << cy << "\n"; // Outputs: 2015
+//
+// ARITHMETIC:
+//
+// Civil-time types support natural arithmetic operators such as addition,
+// subtraction, and difference. Arithmetic operates on the civil-time field
+// indicated in the type's name. Difference requires arguments with the same
+// alignment and returns the answer in units of the alignment.
+//
+// civil_day a(2015, 2, 3);
+// ++a; // 2015-02-04 00:00:00
+// --a; // 2015-02-03 00:00:00
+// civil_day b = a + 1; // 2015-02-04 00:00:00
+// civil_day c = 1 + b; // 2015-02-05 00:00:00
+// int n = c - a; // n = 2 (civil days)
+// int m = c - civil_month(c); // Won't compile: different types.
+//
+// EXAMPLE: Adding a month to January 31.
+//
+// One of the classic questions that arises when considering a civil-time
+// library (or a date library or a date/time library) is this: "What happens
+// when you add a month to January 31?" This is an interesting question
+// because there could be a number of possible answers:
+//
+// 1. March 3 (or 2 if a leap year). This may make sense if the operation
+// wants the equivalent of February 31.
+// 2. February 28 (or 29 if a leap year). This may make sense if the operation
+// wants the last day of January to go to the last day of February.
+// 3. Error. The caller may get some error, an exception, an invalid date
+// object, or maybe false is returned. This may make sense because there is
+// no single unambiguously correct answer to the question.
+//
+// Practically speaking, any answer that is not what the programmer intended
+// is the wrong answer.
+//
+// This civil-time library avoids the problem by making it impossible to ask
+// ambiguous questions. All civil-time objects are aligned to a particular
+// civil-field boundary (such as aligned to a year, month, day, hour, minute,
+// or second), and arithmetic operates on the field to which the object is
+// aligned. This means that in order to "add a month" the object must first be
+// aligned to a month boundary, which is equivalent to the first day of that
+// month.
+//
+// Of course, there are ways to compute an answer the question at hand using
+// this civil-time library, but they require the programmer to be explicit
+// about the answer they expect. To illustrate, let's see how to compute all
+// three of the above possible answers to the question of "Jan 31 plus 1
+// month":
+//
+// const civil_day d(2015, 1, 31);
+//
+// // Answer 1:
+// // Add 1 to the month field in the constructor, and rely on normalization.
+// const auto ans_normalized = civil_day(d.year(), d.month() + 1, d.day());
+// // ans_normalized == 2015-03-03 (aka Feb 31)
+//
+// // Answer 2:
+// // Add 1 to month field, capping to the end of next month.
+// const auto next_month = civil_month(d) + 1;
+// const auto last_day_of_next_month = civil_day(next_month + 1) - 1;
+// const auto ans_capped = std::min(ans_normalized, last_day_of_next_month);
+// // ans_capped == 2015-02-28
+//
+// // Answer 3:
+// // Signal an error if the normalized answer is not in next month.
+// if (civil_month(ans_normalized) != next_month) {
+// // error, month overflow
+// }

+// and %E*z also accept the same inputs.
+//
+// %Y consumes as many numeric characters as it can, so the matching data

+//
+// "1970-01-01 00:00:00.0 +0000"

+// For example, parsing a std::string of "15:45" (%H:%M) will return a time_point
+// that represents "1970-01-01 15:45:00.0 +0000".
+//
+// Note that parse() returns time instants, so it makes most sense to parse
+// fully-specified date/time strings that include a UTC offset (%z, %Ez, or
+// %E*z).
+//
+// Note also that parse() only heeds the fields year, month, day, hour,
+// minute, (fractional) second, and UTC offset. Other fields, like weekday (%a
+// or %A), while parsed for syntactic validity, are ignored in the conversion.
+//
+// Date and time fields that are out-of-range will be treated as errors rather
+// than normalizing them like cctz::civil_second() would do. For example, it
+// is an error to parse the date "Oct 32, 2013" because 32 is out of range.
+//

+testdata/zoneinfo contains time-zone data files that may be used with CCTZ.
+Install them in a location referenced by the ${TZDIR} environment variable.
+Symbolic and hard links have been eliminated for portability.
+
+On Linux systems the distribution's versions of these files can probably
+already be found in the default ${TZDIR} location, /usr/share/zoneinfo.

+New versions can be generated using the following shell script.

+# This file contains a table of two-letter country codes. Columns are

+# All text uses UTF-8 encoding. The columns of the table are as follows:
+#
+# 1. ISO 3166-1 alpha-2 country code, current as of

+# http://isotc.iso.org/livelink/livelink/Open/16944257
+# 2. The usual English name for the coded region,
+# chosen so that alphabetic sorting of subsets produces helpful lists.
+# This is not the same as the English name in the ISO 3166 tables.
+#
+# The table is sorted by country code.

+# This table is intended as an aid for users, to help them select time
+# zone data appropriate for their practical needs. It is not intended

+# tz zone descriptions
+#
+# This file is in the public domain.

+# From Paul Eggert (2017-10-01):
+# This file contains a table where each row stands for a zone where
+# civil time stamps have agreed since 1970. Columns are separated by
+# a single tab. Lines beginning with '#' are comments. All text uses
+# UTF-8 encoding. The columns of the table are as follows:
+#
+# 1. The countries that overlap the zone, as a comma-separated list
+# of ISO 3166 2-character country codes. See the file 'iso3166.tab'.
+# 2. Latitude and longitude of the zone's principal location
+# in ISO 6709 sign-degrees-minutes-seconds format,
+# either ±DDMM±DDDMM or ±DDMMSS±DDDMMSS,
+# first latitude (+ is north), then longitude (+ is east).
+# 3. Zone name used in value of TZ environment variable.
+# Please see the theory.html file for how zone names are chosen.
+# If multiple zones overlap a country, each has a row in the
+# table, with each column 1 containing the country code.
+# 4. Comments; present if and only if a country has multiple zones.
+#
+# If a zone covers multiple countries, the most-populous city is used,
+# and that country is listed first in column 1; any other countries
+# are listed alphabetically by country code. The table is sorted
+# first by country code, then (if possible) by an order within the
+# country that (1) makes some geographical sense, and (2) puts the
+# most populous zones first, where that does not contradict (1).
+#
+# This table is intended as an aid for users, to help them select time
+# zone data entries appropriate for their practical needs. It is not
+# intended to take or endorse any position on legal or territorial claims.

+// * `absl::Time` defines an absolute, specific instance in time
+// * `absl::Duration` defines a signed, fixed-length span of time

+// Duration
+//
+// The `absl::Duration` class represents a signed, fixed-length span of time.
+// A `Duration` is generated using a unit-specific factory function, or is
+// the result of subtracting one `absl::Time` from another. Durations behave
+// like unit-safe integers and they support all the natural integer-like
+// arithmetic operations. Arithmetic overflows and saturates at +/- infinity.
+// `Duration` should be passed by value rather than const reference.
+//
+// Factory functions `Nanoseconds()`, `Microseconds()`, `Milliseconds()`,
+// `Seconds()`, `Minutes()`, `Hours()` and `InfiniteDuration()` allow for
+// creation of constexpr `Duration` values
+//
+// Examples:
+//
+// constexpr absl::Duration ten_ns = absl::Nanoseconds(10);
+// constexpr absl::Duration min = absl::Minutes(1);
+// constexpr absl::Duration hour = absl::Hours(1);
+// absl::Duration dur = 60 * min; // dur == hour
+// absl::Duration half_sec = absl::Milliseconds(500);
+// absl::Duration quarter_sec = 0.25 * absl::Seconds(1);
+//
+// `Duration` values can be easily converted to an integral number of units
+// using the division operator.
+//
+// Example:
+//
+// constexpr absl::Duration dur = absl::Milliseconds(1500);
+// int64_t ns = dur / absl::Nanoseconds(1); // ns == 1500000000
+// int64_t ms = dur / absl::Milliseconds(1); // ms == 1500
+// int64_t sec = dur / absl::Seconds(1); // sec == 1 (subseconds truncated)
+// int64_t min = dur / absl::Minutes(1); // min == 0
+//
+// See the `IDivDuration()` and `FDivDuration()` functions below for details on
+// how to access the fractional parts of the quotient.
+//
+// Alternatively, conversions can be performed using helpers such as
+// `ToInt64Microseconds()` and `ToDoubleSeconds()`.

+// Time
+//
+// An `absl::Time` represents a specific instant in time. Arithmetic operators
+// are provided for naturally expressing time calculations. Instances are
+// created using `absl::Now()` and the `absl::From*()` factory functions that
+// accept the gamut of other time representations. Formatting and parsing
+// functions are provided for conversion to and from strings. `absl::Time`
+// should be passed by value rather than const reference.
+//
+// `absl::Time` assumes there are 60 seconds in a minute, which means the
+// underlying time scales must be "smeared" to eliminate leap seconds.
+// See https://developers.google.com/time/smear.
+//
+// Even though `absl::Time` supports a wide range of timestamps, exercise
+// caution when using values in the distant past. `absl::Time` uses the
+// Proleptic Gregorian calendar, which extends the Gregorian calendar backward
+// to dates before its introduction in 1582.
+// See https://en.wikipedia.org/wiki/Proleptic_Gregorian_calendar
+// for more information. Use the ICU calendar classes to convert a date in
+// some other calendar (http://userguide.icu-project.org/datetime/calendar).
+//
+// Similarly, standardized time zones are a reasonably recent innovation, with
+// the Greenwich prime meridian being established in 1884. The TZ database
+// itself does not profess accurate offsets for timestamps prior to 1970. The
+// breakdown of future timestamps is subject to the whim of regional
+// governments.
+//
+// The `absl::Time` class represents an instant in time as a count of clock
+// ticks of some granularity (resolution) from some starting point (epoch).
+//
+//
+// `absl::Time` uses a resolution that is high enough to avoid loss in
+// precision, and a range that is wide enough to avoid overflow, when
+// converting between tick counts in most Google time scales (i.e., precision
+// of at least one nanosecond, and range +/-100 billion years). Conversions
+// between the time scales are performed by truncating (towards negative
+// infinity) to the nearest representable point.
+//
+// Examples:
+//
+// absl::Time t1 = ...;
+// absl::Time t2 = t1 + absl::Minutes(2);
+// absl::Duration d = t2 - t1; // == absl::Minutes(2)
+// absl::Time::Breakdown bd = t1.In(absl::LocalTimeZone());

+// `absl::TimeZone`, to a time instant (an absolute time), as returned by
+// `absl::ConvertDateTime()`. (Subseconds must be handled separately.)
+//
+// It is possible, though, for a caller to try to convert values that
+// do not represent an actual or unique instant in time (due to a shift
+// in UTC offset in the `absl::TimeZone`, which results in a discontinuity in
+// the civil-time components). For example, a daylight-saving-time
+// transition skips or repeats civil times---in the United States, March
+// 13, 2011 02:15 never occurred, while November 6, 2011 01:15 occurred
+// twice---so requests for such times are not well-defined.
+//
+// To account for these possibilities, `absl::TimeConversion` is richer
+// than just a single `absl::Time`. When the civil time is skipped or
+// repeated, `absl::ConvertDateTime()` returns times calculated using the
+// pre-transition and post-transition UTC offsets, plus the transition
+// time itself.
+//
+// Examples:
+//
+// absl::TimeZone lax;

+// This header file define the `absl::any` type for holding a type-safe value
+// of any type. The 'absl::any` type is useful for providing a way to hold
+// something that is, as yet, unspecified. Such unspecified types
+// traditionally are passed between API boundaries until they are later cast to
+// their "destination" types. To cast to such a destination type, use
+// `absl::any_cast()`. Note that when casting an `absl::any`, you must cast it
+// to an explicit type; implicit conversions will throw.
+//
+// Example:
+//
+// auto a = absl::any(65);
+// absl::any_cast<int>(a); // 65
+// absl::any_cast<char>(a); // throws absl::bad_any_cast
+// absl::any_cast<std::string>(a); // throws absl::bad_any_cast
+//
+// `absl::any` is a C++11 compatible version of the C++17 `std::any` abstraction
+// and is designed to be a drop-in replacement for code compliant with C++17.
+//
+// Traditionally, the behavior of casting to a temporary unspecified type has
+// been accomplished with the `void *` paradigm, where the pointer was to some
+// other unspecified type. `absl::any` provides an "owning" version of `void *`
+// that avoids issues of pointer management.
+//
+// Note: just as in the case of `void *`, use of `absl::any` (and its C++17
+// version `std::any`) is a code smell indicating that your API might not be
+// constructed correctly. We have seen that most uses of `any` are unwarranted,
+// and `absl::any`, like `std::any`, is difficult to use properly. Before using
+// this abstraction, make sure that you should not instead be rewriting your
+// code to be more specific.
+//
+// Abseil expects to release an `absl::variant` type shortly (a C++11 compatible
+// version of the C++17 `std::variant), which is generally preferred for use
+// over `absl::any`.

+// An `absl::any` object provides the facility to either store an instance of a
+// type, known as the "contained object", or no value. An `absl::any` is used to
+// store values of types that are unknown at compile time. The `absl::any`
+// object, when containing a value, must contain a value type; storing a
+// reference type is neither desired nor supported.
+//
+// An `absl::any` can only store a type that is copy-constructable; move-only
+// types are not allowed within an `any` object.
+//
+// Example:
+//
+// auto a = absl::any(65); // Literal, copyable
+// auto b = absl::any(std::vector<int>()); // Default-initialized, copyable
+// std::unique_ptr<Foo> my_foo;
+// auto c = absl::any(std::move(my_foo)); // Error, not copy-constructable
+//
+// Note that `absl::any` makes use of decayed types (`absl::decay_t` in this
+// context) to remove const-volatile qualifiers (known as "cv qualifiers"),
+// decay functions to function pointers, etc. We essentially "decay" a given
+// type into its essential type.
+//
+// `absl::any` makes use of decayed types when determining the basic type `T` of
+// the value to store in the any's contained object. In the documentation below,
+// we explicitly denote this by using the phrase "a decayed type of `T`".
+//
+// Example:
+//
+// const int a = 4;
+// absl::any foo(a); // Decay ensures we store an "int", not a "const int&".
+//
+// void my_function() {}
+// absl::any bar(my_function); // Decay ensures we store a function pointer.
+//
+// `absl::any` is a C++11 compatible version of the C++17 `std::any` abstraction
+// and is designed to be a drop-in replacement for code compliant with C++17.

+// This header file defines the `absl::optional` type for holding a value which
+// may or may not be present. This type is useful for providing value semantics
+// for operations that may either wish to return or hold "something-or-nothing".
+//
+// Example:
+//
+// // A common way to signal operation failure is to provide an output
+// // parameter and a bool return type:
+// bool AcquireResource(const Input&, Resource * out);
+//
+// // Providing an absl::optional return type provides a cleaner API:
+// absl::optional<Resource> AcquireResource(const Input&);
+//
+// `absl::optional` is a C++11 compatible version of the C++17 `std::optional`
+// abstraction and is designed to be a drop-in replacement for code compliant
+// with C++17.

+// A value of type `absl::optional<T>` holds either a value of `T` or an
+// "empty" value. When it holds a value of `T`, it stores it as a direct
+// sub-object, so `sizeof(optional<T>)` is approximately
+// `sizeof(T) + sizeof(bool)`.
+//
+// This implementation is based on the specification in the latest draft of the
+// C++17 `std::optional` specification as of May 2017, section 20.6.
+//
+// Differences between `absl::optional<T>` and `std::optional<T>` include:
+//
+// * `constexpr` is not used for non-const member functions.
+// (dependency on some differences between C++11 and C++14.)
+// * `absl::nullopt` and `absl::in_place` are not declared `constexpr`. We
+// need the inline variable support in C++17 for external linkage.
+// * Throws `absl::bad_optional_access` instead of
+// `std::bad_optional_access`.
+// * `optional::swap()` and `absl::swap()` relies on
+// `std::is_(nothrow_)swappable()`, which has been introduced in C++17.
+// As a workaround, we assume `is_swappable()` is always `true`
+// and `is_nothrow_swappable()` is the same as `std::is_trivial()`.
+// * `make_optional()` cannot be declared `constexpr` due to the absence of
+// guaranteed copy elision.
+// * The move constructor's `noexcept` specification is stronger, i.e. if the
+// default allocator is non-throwing (via setting
+// `ABSL_ALLOCATOR_NOTHROW`), it evaluates to `noexcept(true)`, because
+// we assume
+// a) move constructors should only throw due to allocation failure and
+// b) if T's move constructor allocates, it uses the same allocation
+// function as the default allocator.

+//
+// This header file defines a `Span<T>` type for holding a view of an existing
+// array of data. The `Span` object, much like the `absl::string_view` object,
+// does not own such data itself. A span provides a lightweight way to pass
+// around view of such data.
+//
+// Additionally, this header file defines `MakeSpan()` and `MakeConstSpan()`
+// factory functions, for clearly creating spans of type `Span<T>` or read-only
+// `Span<const T>` when such types may be difficult to identify due to issues
+// with implicit conversion.
+//
+// The C++ standards committee currently has a proposal for a `std::span` type,
+// (http://wg21.link/p0122), which is not yet part of the standard (though may
+// become part of C++20). As of August 2017, the differences between
+// `absl::Span` and this proposal are:
+// * `absl::Span` uses `size_t` for `size_type`
+// * `absl::Span` has no `operator()`
+// * `absl::Span` has no constructors for `std::unique_ptr` or
+// `std::shared_ptr`
+// * `absl::Span` has the factory functions `MakeSpan()` and
+// `MakeConstSpan()`
+// * `absl::Span` has `front()` and `back()` methods
+// * bounds-checked access to `absl::Span` is accomplished with `at()`
+// * `absl::Span` has compiler-provided move and copy constructors and
+// assignment. This is due to them being specified as `constexpr`, but that
+// implies const in C++11.
+// * `absl::Span` has no `element_type` or `index_type` typedefs
+// * A read-only `absl::Span<const T>` can be implicitly constructed from an
+// initializer list.
+// * `absl::Span` has no `bytes()`, `size_bytes()`, `as_bytes()`, or
+// `as_mutable_bytes()` methods
+// * `absl::Span` has no static extent template parameter, nor constructors
+// which exist only because of the static extent parameter.
+// * `absl::Span` has an explicit mutable-reference constructor
+//

+// Span
+//------------------------------------------------------------------------------
+//
+// A `Span` is an "array view" type for holding a view of a contiguous data
+// array; the `Span` object does not and cannot own such data itself. A span
+// provides an easy way to provide overloads for anything operating on
+// contiguous sequences without needing to manage pointers and array lengths
+// manually.
+
+// A span is conceptually a pointer (ptr) and a length (size) into an already
+// existing array of contiguous memory; the array it represents references the
+// elements "ptr[0] .. ptr[size-1]". Passing a properly-constructed `Span`
+// instead of raw pointers avoids many issues related to index out of bounds
+// errors.
+//
+// Spans may also be constructed from containers holding contiguous sequences.
+// Such containers must supply `data()` and `size() const` methods (e.g
+// `std::vector<T>`, `absl::InlinedVector<T, N>`). All implicit conversions to
+// `absl::Span` from such containers will create spans of type `const T`;
+// spans which can mutate their values (of type `T`) must use explicit
+// constructors.
+//
+// A `Span<T>` is somewhat analogous to an `absl::string_view`, but for an array
+// of elements of type `T`. A user of `Span` must ensure that the data being
+// pointed to outlives the `Span` itself.
+//
+// You can construct a `Span<T>` in several ways:
+//
+// * Explicitly from a reference to a container type
+// * Explicitly from a pointer and size
+// * Implicitly from a container type (but only for spans of type `const T`)
+// * Using the `MakeSpan()` or `MakeConstSpan()` factory functions.
+//
+// Examples:
+//
+// // Construct a Span explicitly from a container:
+// std::vector<int> v = {1, 2, 3, 4, 5};
+// auto span = absl::Span<const int>(v);
+//
+// // Construct a Span explicitly from a C-style array:
+// int a[5] = {1, 2, 3, 4, 5};
+// auto span = absl::Span<const int>(a);
+//
+// // Construct a Span implicitly from a container
+// void MyRoutine(absl::Span<const int> a) {
+// ...
+// }
+// std::vector v = {1,2,3,4,5};
+// MyRoutine(v) // convert to Span<const T>
+//
+// Note that `Span` objects, in addition to requiring that the memory they
+// point to remains alive, must also ensure that such memory does not get
+// reallocated. Therefore, to avoid undefined behavior, containers with
+// associated span views should not invoke operations that may reallocate memory
+// (such as resizing) or invalidate iterators into the container.
+//
+// One common use for a `Span` is when passing arguments to a routine that can
+// accept a variety of array types (e.g. a `std::vector`, `absl::InlinedVector`,
+// a C-style array, etc.). Instead of creating overloads for each case, you
+// can simply specify a `Span` as the argument to such a routine.
+//
+// Example:
+//
+// void MyRoutine(absl::Span<const int> a) {
+// ...
+// }
+//
+// std::vector v = {1,2,3,4,5};
+// MyRoutine(v);
+//
+// absl::InlinedVector<int, 4> my_inline_vector;
+// MyRoutine(my_inline_vector);
+//
+// // Explicit constructor from pointer,size
+// int* my_array = new int[10];
+// MyRoutine(absl::Span<const int>(my_array, 10));

+// MakeSpan()

+// Constructs a mutable `Span<T>`, deducing `T` automatically from either a
+// container or pointer+size.
+//
+// Because a read-only `Span<const T>` is implicitly constructed from container
+// types regardless of whether the container itself is a const container,
+// constructing mutable spans of type `Span<T>` from containers requires
+// explicit constructors. The container-accepting version of `MakeSpan()`
+// deduces the type of `T` by the constness of the pointer received from the
+// container's `data()` member. Similarly, the pointer-accepting version returns
+// a `Span<const T>` if `T` is `const`, and a `Span<T>` otherwise.
+//
+// Examples:
+//
+// void MyRoutine(absl::Span<MyComplicatedType> a) {
+// ...
+// };
+// // my_vector is a container of non-const types
+// std::vector<MyComplicatedType> my_vector;
+//
+// // Constructing a Span implicitly attempts to create a Span of type
+// // `Span<const T>`
+// MyRoutine(my_vector); // error, type mismatch
+//
+// // Explicitly constructing the Span is verbose
+// MyRoutine(absl::Span<MyComplicatedType>(my_vector));
+//
+// // Use MakeSpan() to make an absl::Span<T>
+// MyRoutine(absl::MakeSpan(my_vector));
+//
+// // Construct a span from an array ptr+size

+//
+// This header file defines an `absl::variant` type for holding a type-safe
+// value of some prescribed set of types (noted as alternative types), and
+// associated functions for managing variants.
+//
+// The `absl::variant` type is a form of type-safe union. An `absl::variant`
+// should always hold a value of one of its alternative types (except in the
+// "valueless by exception state" -- see below). A default-constructed
+// `absl::variant` will hold the value of its first alternative type, provided
+// it is default-constructable.
+//
+// In exceptional cases due to error, an `absl::variant` can hold no
+// value (known as a "valueless by exception" state), though this is not the
+// norm.
+//
+// As with `absl::optional`, an `absl::variant` -- when it holds a value --
+// allocates a value of that type directly within the `variant` itself; it
+// cannot hold a reference, array, or the type `void`; it can, however, hold a
+// pointer to externally managed memory.
+//
+// `absl::variant` is a C++11 compatible version of the C++17 `std::variant`
+// abstraction and is designed to be a drop-in replacement for code compliant
+// with C++17.

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement
+(CLA).
+
+ * If you are an individual writing original source code and you're sure you
+ own the intellectual property, then you'll need to sign an
+ [individual CLA](https://developers.google.com/open-source/cla/individual).
+ * If you work for a company that wants to allow you to contribute your work,
+ then you'll need to sign a
+ [corporate CLA](https://developers.google.com/open-source/cla/corporate).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch
+
+1. Submit an issue describing your proposed change to the
+ [issue tracker](https://github.com/google/googletest).
+1. Please don't mix more than one logical change per submittal,
+ because it makes the history hard to follow. If you want to make a
+ change that doesn't have a corresponding issue in the issue
+ tracker, please create one.
+1. Also, coordinate with team members that are listed on the issue in
+ question. This ensures that work isn't being duplicated and
+ communicating your plan early also generally leads to better
+ patches.
+1. If your proposed change is accepted, and you haven't already done so, sign a
+ Contributor License Agreement (see details above).
+1. Fork the desired repo, develop and test your code changes.
+1. Ensure that your code adheres to the existing style in the sample to which
+ you are contributing.
+1. Ensure that your code has an appropriate set of unit tests which all pass.
+1. Submit a pull request.
+
+If you are a Googler, it is preferable to first create an internal change and
+have it reviewed and submitted, and then create an upstreaming pull
+request here.
+
+## The Google Test and Google Mock Communities ##
+
+The Google Test community exists primarily through the
+[discussion group](http://groups.google.com/group/googletestframework)
+and the GitHub repository.
+Likewise, the Google Mock community exists primarily through their own
+[discussion group](http://groups.google.com/group/googlemock).
+You are definitely encouraged to contribute to the
+discussion and you can also help us to keep the effectiveness of the
+group high by following and promoting the guidelines listed here.
+
+### Please Be Friendly ###
+
+Showing courtesy and respect to others is a vital part of the Google
+culture, and we strongly encourage everyone participating in Google
+Test development to join us in accepting nothing less. Of course,
+being courteous is not the same as failing to constructively disagree
+with each other, but it does mean that we should be respectful of each
+other when enumerating the 42 technical reasons that a particular
+proposal may not be the best choice. There's never a reason to be
+antagonistic or dismissive toward anyone who is sincerely trying to
+contribute to a discussion.
+
+Sure, C++ testing is serious business and all that, but it's also
+a lot of fun. Let's keep it that way. Let's strive to be one of the
+friendliest communities in all of open source.
+
+As always, discuss Google Test in the official GoogleTest discussion group.
+You don't have to actually submit code in order to sign up. Your participation
+itself is a valuable contribution.
+
+## Style
+
+To keep the source consistent, readable, diffable and easy to merge,
+we use a fairly rigid coding style, as defined by the [google-styleguide](https://github.com/google/styleguide) project. All patches will be expected
+to conform to the style outlined [here](https://google.github.io/styleguide/cppguide.html).
+
+## Requirements for Contributors ###
+
+If you plan to contribute a patch, you need to build Google Test,
+Google Mock, and their own tests from a git checkout, which has
+further requirements:
+
+ * [Python](https://www.python.org/) v2.3 or newer (for running some of
+ the tests and re-generating certain source files from templates)
+ * [CMake](https://cmake.org/) v2.6.4 or newer
+ * [GNU Build System](https://en.wikipedia.org/wiki/GNU_Build_System)
+ including automake (>= 1.9), autoconf (>= 2.59), and
+ libtool / libtoolize.
+
+## Developing Google Test ##
+
+This section discusses how to make your own changes to Google Test.
+
+### Testing Google Test Itself ###
+
+To make sure your changes work as intended and don't break existing
+functionality, you'll want to compile and run Google Test's own tests.
+For that you can use CMake:
+
+ mkdir mybuild
+ cd mybuild
+ cmake -Dgtest_build_tests=ON ${GTEST_DIR}
+
+Make sure you have Python installed, as some of Google Test's tests
+are written in Python. If the cmake command complains about not being
+able to find Python (`Could NOT find PythonInterp (missing:
+PYTHON_EXECUTABLE)`), try telling it explicitly where your Python
+executable can be found:
+
+ cmake -DPYTHON_EXECUTABLE=path/to/python -Dgtest_build_tests=ON ${GTEST_DIR}
+
+Next, you can build Google Test and all of its own tests. On \*nix,
+this is usually done by 'make'. To run the tests, do
+
+ make test
+
+All tests should pass.
+
+### Regenerating Source Files ##
+
+Some of Google Test's source files are generated from templates (not
+in the C++ sense) using a script.
+For example, the
+file include/gtest/internal/gtest-type-util.h.pump is used to generate
+gtest-type-util.h in the same directory.
+
+You don't need to worry about regenerating the source files
+unless you need to modify them. You would then modify the
+corresponding `.pump` files and run the '[pump.py](googletest/scripts/pump.py)'
+generator script. See the [Pump Manual](googletest/docs/PumpManual.md).
+
+## Developing Google Mock ###
+
+This section discusses how to make your own changes to Google Mock.
+
+#### Testing Google Mock Itself ####
+
+To make sure your changes work as intended and don't break existing
+functionality, you'll want to compile and run Google Test's own tests.
+For that you'll need Autotools. First, make sure you have followed
+the instructions above to configure Google Mock.
+Then, create a build output directory and enter it. Next,
+
+ ${GMOCK_DIR}/configure # try --help for more info
+
+Once you have successfully configured Google Mock, the build steps are
+standard for GNU-style OSS packages.
+
+ make # Standard makefile following GNU conventions
+ make check # Builds and runs all tests - all should pass.
+
+Note that when building your project against Google Mock, you are building
+against Google Test as well. There is no need to configure Google Test
+separately.

+# Google Test #
+
+[](https://travis-ci.org/google/googletest)
+[](https://ci.appveyor.com/project/GoogleTestAppVeyor/googletest/branch/master)
+
+Welcome to **Google Test**, Google's C++ test framework!
+
+This repository is a merger of the formerly separate GoogleTest and
+GoogleMock projects. These were so closely related that it makes sense to
+maintain and release them together.
+
+Please see the project page above for more information as well as the
+mailing list for questions, discussions, and development. There is
+also an IRC channel on [OFTC](https://webchat.oftc.net/) (irc.oftc.net) #gtest available. Please
+join us!
+
+Getting started information for **Google Test** is available in the
+[Google Test Primer](googletest/docs/Primer.md) documentation.
+
+**Google Mock** is an extension to Google Test for writing and using C++ mock
+classes. See the separate [Google Mock documentation](googlemock/README.md).
+
+More detailed documentation for googletest (including build instructions) are
+in its interior [googletest/README.md](googletest/README.md) file.
+
+## Features ##
+
+ * An [xUnit](https://en.wikipedia.org/wiki/XUnit) test framework.
+ * Test discovery.
+ * A rich set of assertions.
+ * User-defined assertions.
+ * Death tests.
+ * Fatal and non-fatal failures.
+ * Value-parameterized tests.
+ * Type-parameterized tests.
+ * Various options for running the tests.
+ * XML test report generation.
+
+## Platforms ##
+
+Google test has been used on a variety of platforms:
+
+ * Linux
+ * Mac OS X
+ * Windows
+ * Cygwin
+ * MinGW
+ * Windows Mobile
+ * Symbian
+
+## Who Is Using Google Test? ##
+
+In addition to many internal projects at Google, Google Test is also used by
+the following notable projects:
+
+ * The [Chromium projects](http://www.chromium.org/) (behind the Chrome
+ browser and Chrome OS).
+ * The [LLVM](http://llvm.org/) compiler.

+## Related Open Source Projects ##
+
+[GTest Runner](https://github.com/nholthaus/gtest-runner) is a Qt5 based automated test-runner and Graphical User Interface with powerful features for Windows and Linux platforms.
+
+[Google Test UI](https://github.com/ospector/gtest-gbar) is test runner that runs
+your test binary, allows you to track its progress via a progress bar, and
+displays a list of test failures. Clicking on one shows failure text. Google
+Test UI is written in C#.
+
+[GTest TAP Listener](https://github.com/kinow/gtest-tap-listener) is an event
+listener for Google Test that implements the
+[TAP protocol](https://en.wikipedia.org/wiki/Test_Anything_Protocol) for test
+result output. If your test runner understands TAP, you may find it useful.
+
+[gtest-parallel](https://github.com/google/gtest-parallel) is a test runner that
+runs tests from your binary in parallel to provide significant speed-up.
+
+## Requirements ##
+
+Google Test is designed to have fairly minimal requirements to build
+and use with your projects, but there are some. Currently, we support
+Linux, Windows, Mac OS X, and Cygwin. We will also make our best
+effort to support other platforms (e.g. Solaris, AIX, and z/OS).
+However, since core members of the Google Test project have no access
+to these platforms, Google Test may have outstanding issues there. If
+you notice any problems on your platform, please notify
+[googletestframework@googlegroups.com](https://groups.google.com/forum/#!forum/googletestframework). Patches for fixing them are
+even more welcome!
+
+### Linux Requirements ###
+
+These are the base requirements to build and use Google Test from a source
+package (as described below):
+
+ * GNU-compatible Make or gmake
+ * POSIX-standard shell
+ * POSIX(-2) Regular Expressions (regex.h)
+ * A C++98-standard-compliant compiler
+
+### Windows Requirements ###
+
+ * Microsoft Visual C++ 2015 or newer
+
+### Cygwin Requirements ###
+
+ * Cygwin v1.5.25-14 or newer
+
+### Mac OS X Requirements ###
+
+ * Mac OS X v10.4 Tiger or newer
+ * Xcode Developer Tools
+

+Changes for 1.7.0:
+
+* All new improvements in Google Test 1.7.0.
+* New feature: matchers DoubleNear(), FloatNear(),
+ NanSensitiveDoubleNear(), NanSensitiveFloatNear(),
+ UnorderedElementsAre(), UnorderedElementsAreArray(), WhenSorted(),
+ WhenSortedBy(), IsEmpty(), and SizeIs().
+* Improvement: Google Mock can now be built as a DLL.
+* Improvement: when compiled by a C++11 compiler, matchers AllOf()
+ and AnyOf() can accept an arbitrary number of matchers.
+* Improvement: when compiled by a C++11 compiler, matchers
+ ElementsAreArray() can accept an initializer list.
+* Improvement: when exceptions are enabled, a mock method with no
+ default action now throws instead crashing the test.
+* Improvement: added class testing::StringMatchResultListener to aid
+ definition of composite matchers.
+* Improvement: function return types used in MOCK_METHOD*() macros can
+ now contain unprotected commas.
+* Improvement (potentially breaking): EXPECT_THAT() and ASSERT_THAT()
+ are now more strict in ensuring that the value type and the matcher
+ type are compatible, catching potential bugs in tests.
+* Improvement: Pointee() now works on an optional<T>.
+* Improvement: the ElementsAreArray() matcher can now take a vector or
+ iterator range as input, and makes a copy of its input elements
+ before the conversion to a Matcher.
+* Improvement: the Google Mock Generator can now generate mocks for
+ some class templates.
+* Bug fix: mock object destruction triggerred by another mock object's
+ destruction no longer hangs.
+* Improvement: Google Mock Doctor works better with newer Clang and
+ GCC now.
+* Compatibility fixes.
+* Bug/warning fixes.
+
+Changes for 1.6.0:
+
+* Compilation is much faster and uses much less memory, especially
+ when the constructor and destructor of a mock class are moved out of
+ the class body.
+* New matchers: Pointwise(), Each().
+* New actions: ReturnPointee() and ReturnRefOfCopy().
+* CMake support.
+* Project files for Visual Studio 2010.
+* AllOf() and AnyOf() can handle up-to 10 arguments now.
+* Google Mock doctor understands Clang error messages now.
+* SetArgPointee<> now accepts string literals.
+* gmock_gen.py handles storage specifier macros and template return
+ types now.
+* Compatibility fixes.
+* Bug fixes and implementation clean-ups.
+* Potentially incompatible changes: disables the harmful 'make install'
+ command in autotools.
+
+Potentially breaking changes:
+
+* The description string for MATCHER*() changes from Python-style
+ interpolation to an ordinary C++ string expression.
+* SetArgumentPointee is deprecated in favor of SetArgPointee.
+* Some non-essential project files for Visual Studio 2005 are removed.
+
+Changes for 1.5.0:
+
+ * New feature: Google Mock can be safely used in multi-threaded tests
+ on platforms having pthreads.
+ * New feature: function for printing a value of arbitrary type.
+ * New feature: function ExplainMatchResult() for easy definition of
+ composite matchers.
+ * The new matcher API lets user-defined matchers generate custom
+ explanations more directly and efficiently.
+ * Better failure messages all around.
+ * NotNull() and IsNull() now work with smart pointers.
+ * Field() and Property() now work when the matcher argument is a pointer
+ passed by reference.
+ * Regular expression matchers on all platforms.
+ * Added GCC 4.0 support for Google Mock Doctor.
+ * Added gmock_all_test.cc for compiling most Google Mock tests
+ in a single file.
+ * Significantly cleaned up compiler warnings.
+ * Bug fixes, better test coverage, and implementation clean-ups.
+
+ Potentially breaking changes:
+
+ * Custom matchers defined using MatcherInterface or MakePolymorphicMatcher()
+ need to be updated after upgrading to Google Mock 1.5.0; matchers defined
+ using MATCHER or MATCHER_P* aren't affected.
+ * Dropped support for 'make install'.
+
+Changes for 1.4.0 (we skipped 1.2.* and 1.3.* to match the version of
+Google Test):
+
+ * Works in more environments: Symbian and minGW, Visual C++ 7.1.
+ * Lighter weight: comes with our own implementation of TR1 tuple (no
+ more dependency on Boost!).
+ * New feature: --gmock_catch_leaked_mocks for detecting leaked mocks.
+ * New feature: ACTION_TEMPLATE for defining templatized actions.
+ * New feature: the .After() clause for specifying expectation order.
+ * New feature: the .With() clause for specifying inter-argument
+ constraints.
+ * New feature: actions ReturnArg<k>(), ReturnNew<T>(...), and
+ DeleteArg<k>().
+ * New feature: matchers Key(), Pair(), Args<...>(), AllArgs(), IsNull(),
+ and Contains().
+ * New feature: utility class MockFunction<F>, useful for checkpoints, etc.
+ * New feature: functions Value(x, m) and SafeMatcherCast<T>(m).
+ * New feature: copying a mock object is rejected at compile time.
+ * New feature: a script for fusing all Google Mock and Google Test
+ source files for easy deployment.
+ * Improved the Google Mock doctor to diagnose more diseases.
+ * Improved the Google Mock generator script.
+ * Compatibility fixes for Mac OS X and gcc.
+ * Bug fixes and implementation clean-ups.
+
+Changes for 1.1.0:
+
+ * New feature: ability to use Google Mock with any testing framework.
+ * New feature: macros for easily defining new matchers
+ * New feature: macros for easily defining new actions.
+ * New feature: more container matchers.
+ * New feature: actions for accessing function arguments and throwing
+ exceptions.
+ * Improved the Google Mock doctor script for diagnosing compiler errors.
+ * Bug fixes and implementation clean-ups.
+
+Changes for 1.0.0:
+
+ * Initial Open Source release of Google Mock

+## Google Mock ##
+
+The Google C++ mocking framework.
+
+### Overview ###
+
+Google's framework for writing and using C++ mock classes.
+It can help you derive better designs of your system and write better tests.
+
+It is inspired by:
+
+ * [jMock](http://www.jmock.org/),
+ * [EasyMock](http://www.easymock.org/), and
+ * [Hamcrest](http://code.google.com/p/hamcrest/),
+
+and designed with C++'s specifics in mind.
+
+Google mock:
+
+ * lets you create mock classes trivially using simple macros.
+ * supports a rich set of matchers and actions.
+ * handles unordered, partially ordered, or completely ordered expectations.
+ * is extensible by users.
+
+We hope you find it useful!
+
+### Features ###
+
+ * Provides a declarative syntax for defining mocks.
+ * Can easily define partial (hybrid) mocks, which are a cross of real
+ and mock objects.
+ * Handles functions of arbitrary types and overloaded functions.
+ * Comes with a rich set of matchers for validating function arguments.
+ * Uses an intuitive syntax for controlling the behavior of a mock.
+ * Does automatic verification of expectations (no record-and-replay needed).
+ * Allows arbitrary (partial) ordering constraints on
+ function calls to be expressed,.
+ * Lets an user extend it by defining new matchers and actions.
+ * Does not use exceptions.
+ * Is easy to learn and use.
+
+Please see the project page above for more information as well as the
+mailing list for questions, discussions, and development. There is
+also an IRC channel on OFTC (irc.oftc.net) #gtest available. Please
+join us!
+
+Please note that code under [scripts/generator](scripts/generator/) is
+from [cppclean](http://code.google.com/p/cppclean/) and released under
+the Apache License, which is different from Google Mock's license.
+
+## Getting Started ##
+
+If you are new to the project, we suggest that you read the user
+documentation in the following order:
+
+ * Learn the [basics](../../master/googletest/docs/Primer.md) of
+ Google Test, if you choose to use Google Mock with it (recommended).
+ * Read [Google Mock for Dummies](../../master/googlemock/docs/ForDummies.md).
+ * Read the instructions below on how to build Google Mock.
+
+You can also watch Zhanyong's [talk](http://www.youtube.com/watch?v=sYpCyLI47rM) on Google Mock's usage and implementation.
+
+Once you understand the basics, check out the rest of the docs:
+
+ * [CheatSheet](../../master/googlemock/docs/CheatSheet.md) - all the commonly used stuff
+ at a glance.
+ * [CookBook](../../master/googlemock/docs/CookBook.md) - recipes for getting things done,
+ including advanced techniques.
+
+If you need help, please check the
+[KnownIssues](docs/KnownIssues.md) and
+[FrequentlyAskedQuestions](docs/FrequentlyAskedQuestions.md) before
+posting a question on the
+[discussion group](http://groups.google.com/group/googlemock).
+
+
+### Using Google Mock Without Google Test ###
+
+Google Mock is not a testing framework itself. Instead, it needs a
+testing framework for writing tests. Google Mock works seamlessly
+with [Google Test](https://github.com/google/googletest), but
+you can also use it with [any C++ testing framework](../../master/googlemock/docs/ForDummies.md#using-google-mock-with-any-testing-framework).
+
+### Requirements for End Users ###
+
+Google Mock is implemented on top of [Google Test](
+http://github.com/google/googletest/), and depends on it.
+You must use the bundled version of Google Test when using Google Mock.
+
+You can also easily configure Google Mock to work with another testing
+framework, although it will still need Google Test. Please read
+["Using_Google_Mock_with_Any_Testing_Framework"](
+ ../../master/googlemock/docs/ForDummies.md#using-google-mock-with-any-testing-framework)
+for instructions.
+
+Google Mock depends on advanced C++ features and thus requires a more
+modern compiler. The following are needed to use Google Mock:
+
+#### Linux Requirements ####
+
+ * GNU-compatible Make or "gmake"
+ * POSIX-standard shell
+ * POSIX(-2) Regular Expressions (regex.h)
+ * C++98-standard-compliant compiler (e.g. GCC 3.4 or newer)
+
+#### Windows Requirements ####
+
+ * Microsoft Visual C++ 8.0 SP1 or newer
+
+#### Mac OS X Requirements ####
+
+ * Mac OS X 10.4 Tiger or newer
+ * Developer Tools Installed
+
+### Requirements for Contributors ###
+
+We welcome patches. If you plan to contribute a patch, you need to
+build Google Mock and its tests, which has further requirements:
+
+ * Automake version 1.9 or newer
+ * Autoconf version 2.59 or newer
+ * Libtool / Libtoolize
+ * Python version 2.3 or newer (for running some of the tests and
+ re-generating certain source files from templates)
+
+### Building Google Mock ###
+
+#### Using CMake ####
+
+If you have CMake available, it is recommended that you follow the
+[build instructions][gtest_cmakebuild]
+as described for Google Test.
+
+If are using Google Mock with an
+existing CMake project, the section
+[Incorporating Into An Existing CMake Project][gtest_incorpcmake]
+may be of particular interest.
+To make it work for Google Mock you will need to change
+
+ target_link_libraries(example gtest_main)
+
+to
+
+ target_link_libraries(example gmock_main)
+
+This works because `gmock_main` library is compiled with Google Test.
+However, it does not automatically add Google Test includes.
+Therefore you will also have to change
+
+ if (CMAKE_VERSION VERSION_LESS 2.8.11)
+ include_directories("${gtest_SOURCE_DIR}/include")
+ endif()
+
+to
+
+ if (CMAKE_VERSION VERSION_LESS 2.8.11)
+ include_directories(BEFORE SYSTEM
+ "${gtest_SOURCE_DIR}/include" "${gmock_SOURCE_DIR}/include")
+ else()
+ target_include_directories(gmock_main SYSTEM BEFORE INTERFACE
+ "${gtest_SOURCE_DIR}/include" "${gmock_SOURCE_DIR}/include")
+ endif()
+
+This will addtionally mark Google Mock includes as system, which will
+silence compiler warnings when compiling your tests using clang with
+`-Wpedantic -Wall -Wextra -Wconversion`.
+
+
+#### Preparing to Build (Unix only) ####
+
+If you are using a Unix system and plan to use the GNU Autotools build
+system to build Google Mock (described below), you'll need to
+configure it now.
+
+To prepare the Autotools build system:
+
+ cd googlemock
+ autoreconf -fvi
+
+To build Google Mock and your tests that use it, you need to tell your
+build system where to find its headers and source files. The exact
+way to do it depends on which build system you use, and is usually
+straightforward.
+
+This section shows how you can integrate Google Mock into your
+existing build system.
+
+Suppose you put Google Mock in directory `${GMOCK_DIR}` and Google Test
+in `${GTEST_DIR}` (the latter is `${GMOCK_DIR}/gtest` by default). To
+build Google Mock, create a library build target (or a project as
+called by Visual Studio and Xcode) to compile
+
+ ${GTEST_DIR}/src/gtest-all.cc and ${GMOCK_DIR}/src/gmock-all.cc
+
+with
+
+ ${GTEST_DIR}/include and ${GMOCK_DIR}/include
+
+in the system header search path, and
+
+ ${GTEST_DIR} and ${GMOCK_DIR}
+
+in the normal header search path. Assuming a Linux-like system and gcc,
+something like the following will do:
+
+ g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
+ -isystem ${GMOCK_DIR}/include -I${GMOCK_DIR} \
+ -pthread -c ${GTEST_DIR}/src/gtest-all.cc
+ g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
+ -isystem ${GMOCK_DIR}/include -I${GMOCK_DIR} \
+ -pthread -c ${GMOCK_DIR}/src/gmock-all.cc
+ ar -rv libgmock.a gtest-all.o gmock-all.o
+
+(We need -pthread as Google Test and Google Mock use threads.)
+
+Next, you should compile your test source file with
+${GTEST\_DIR}/include and ${GMOCK\_DIR}/include in the header search
+path, and link it with gmock and any other necessary libraries:
+
+ g++ -isystem ${GTEST_DIR}/include -isystem ${GMOCK_DIR}/include \
+ -pthread path/to/your_test.cc libgmock.a -o your_test
+
+As an example, the make/ directory contains a Makefile that you can
+use to build Google Mock on systems where GNU make is available
+(e.g. Linux, Mac OS X, and Cygwin). It doesn't try to build Google
+Mock's own tests. Instead, it just builds the Google Mock library and
+a sample test. You can use it as a starting point for your own build
+script.
+
+If the default settings are correct for your environment, the
+following commands should succeed:
+
+ cd ${GMOCK_DIR}/make
+ make
+ ./gmock_test
+
+If you see errors, try to tweak the contents of
+[make/Makefile](make/Makefile) to make them go away.
+
+### Windows ###
+
+The msvc/2005 directory contains VC++ 2005 projects and the msvc/2010
+directory contains VC++ 2010 projects for building Google Mock and
+selected tests.
+
+Change to the appropriate directory and run "msbuild gmock.sln" to
+build the library and tests (or open the gmock.sln in the MSVC IDE).
+If you want to create your own project to use with Google Mock, you'll
+have to configure it to use the `gmock_config` propety sheet. For that:
+
+ * Open the Property Manager window (View | Other Windows | Property Manager)
+ * Right-click on your project and select "Add Existing Property Sheet..."
+ * Navigate to `gmock_config.vsprops` or `gmock_config.props` and select it.
+ * In Project Properties | Configuration Properties | General | Additional
+ Include Directories, type <path to Google Mock>/include.
+
+### Tweaking Google Mock ###
+
+Google Mock can be used in diverse environments. The default
+configuration may not work (or may not work well) out of the box in
+some environments. However, you can easily tweak Google Mock by
+defining control macros on the compiler command line. Generally,
+these macros are named like `GTEST_XYZ` and you define them to either 1
+or 0 to enable or disable a certain feature.
+
+We list the most frequently used macros below. For a complete list,
+see file [${GTEST\_DIR}/include/gtest/internal/gtest-port.h](
+../googletest/include/gtest/internal/gtest-port.h).
+
+### Choosing a TR1 Tuple Library ###
+
+Google Mock uses the C++ Technical Report 1 (TR1) tuple library
+heavily. Unfortunately TR1 tuple is not yet widely available with all
+compilers. The good news is that Google Test 1.4.0+ implements a
+subset of TR1 tuple that's enough for Google Mock's need. Google Mock
+will automatically use that implementation when the compiler doesn't
+provide TR1 tuple.
+
+Usually you don't need to care about which tuple library Google Test
+and Google Mock use. However, if your project already uses TR1 tuple,
+you need to tell Google Test and Google Mock to use the same TR1 tuple
+library the rest of your project uses, or the two tuple
+implementations will clash. To do that, add
+
+ -DGTEST_USE_OWN_TR1_TUPLE=0
+
+to the compiler flags while compiling Google Test, Google Mock, and
+your tests. If you want to force Google Test and Google Mock to use
+their own tuple library, just add
+
+ -DGTEST_USE_OWN_TR1_TUPLE=1
+
+to the compiler flags instead.
+
+If you want to use Boost's TR1 tuple library with Google Mock, please
+refer to the Boost website (http://www.boost.org/) for how to obtain
+it and set it up.
+
+### As a Shared Library (DLL) ###
+
+Google Mock is compact, so most users can build and link it as a static
+library for the simplicity. Google Mock can be used as a DLL, but the
+same DLL must contain Google Test as well. See
+[Google Test's README][gtest_readme]
+for instructions on how to set up necessary compiler settings.
+
+### Tweaking Google Mock ###
+
+Most of Google Test's control macros apply to Google Mock as well.
+Please see [Google Test's README][gtest_readme] for how to tweak them.
+
+### Upgrading from an Earlier Version ###
+
+We strive to keep Google Mock releases backward compatible.
+Sometimes, though, we have to make some breaking changes for the
+users' long-term benefits. This section describes what you'll need to
+do if you are upgrading from an earlier version of Google Mock.
+
+#### Upgrading from 1.1.0 or Earlier ####
+
+You may need to explicitly enable or disable Google Test's own TR1
+tuple library. See the instructions in section "[Choosing a TR1 Tuple
+Library](../googletest/#choosing-a-tr1-tuple-library)".
+
+#### Upgrading from 1.4.0 or Earlier ####
+
+On platforms where the pthread library is available, Google Test and
+Google Mock use it in order to be thread-safe. For this to work, you
+may need to tweak your compiler and/or linker flags. Please see the
+"[Multi-threaded Tests](../googletest#multi-threaded-tests
+)" section in file Google Test's README for what you may need to do.
+
+If you have custom matchers defined using `MatcherInterface` or
+`MakePolymorphicMatcher()`, you'll need to update their definitions to
+use the new matcher API (
+[monomorphic](./docs/CookBook.md#writing-new-monomorphic-matchers),
+[polymorphic](./docs/CookBook.md#writing-new-polymorphic-matchers)).
+Matchers defined using `MATCHER()` or `MATCHER_P*()` aren't affected.
+
+Happy testing!

+# Defining a Mock Class #
+
+## Mocking a Normal Class ##
+
+Given
+```
+class Foo {
+ ...
+ virtual ~Foo();
+ virtual int GetSize() const = 0;
+ virtual string Describe(const char* name) = 0;
+ virtual string Describe(int type) = 0;
+ virtual bool Process(Bar elem, int count) = 0;
+};
+```
+(note that `~Foo()` **must** be virtual) we can define its mock as
+```
+#include "gmock/gmock.h"
+
+class MockFoo : public Foo {
+ MOCK_CONST_METHOD0(GetSize, int());
+ MOCK_METHOD1(Describe, string(const char* name));
+ MOCK_METHOD1(Describe, string(int type));
+ MOCK_METHOD2(Process, bool(Bar elem, int count));
+};
+```
+
+To create a "nice" mock object which ignores all uninteresting calls,
+or a "strict" mock object, which treats them as failures:
+```
+NiceMock<MockFoo> nice_foo; // The type is a subclass of MockFoo.
+StrictMock<MockFoo> strict_foo; // The type is a subclass of MockFoo.
+```
+
+## Mocking a Class Template ##
+
+To mock
+```
+template <typename Elem>
+class StackInterface {
+ public:
+ ...
+ virtual ~StackInterface();
+ virtual int GetSize() const = 0;
+ virtual void Push(const Elem& x) = 0;
+};
+```
+(note that `~StackInterface()` **must** be virtual) just append `_T` to the `MOCK_*` macros:
+```
+template <typename Elem>
+class MockStack : public StackInterface<Elem> {
+ public:
+ ...
+ MOCK_CONST_METHOD0_T(GetSize, int());
+ MOCK_METHOD1_T(Push, void(const Elem& x));
+};
+```
+
+## Specifying Calling Conventions for Mock Functions ##
+
+If your mock function doesn't use the default calling convention, you
+can specify it by appending `_WITH_CALLTYPE` to any of the macros
+described in the previous two sections and supplying the calling
+convention as the first argument to the macro. For example,
+```
+ MOCK_METHOD1_WITH_CALLTYPE(STDMETHODCALLTYPE, Foo, bool(int n));
+ MOCK_CONST_METHOD2_WITH_CALLTYPE(STDMETHODCALLTYPE, Bar, int(double x, double y));
+```
+where `STDMETHODCALLTYPE` is defined by `<objbase.h>` on Windows.
+
+# Using Mocks in Tests #
+
+The typical flow is:
+ 1. Import the Google Mock names you need to use. All Google Mock names are in the `testing` namespace unless they are macros or otherwise noted.
+ 1. Create the mock objects.
+ 1. Optionally, set the default actions of the mock objects.
+ 1. Set your expectations on the mock objects (How will they be called? What wil they do?).
+ 1. Exercise code that uses the mock objects; if necessary, check the result using [Google Test](../../googletest/) assertions.
+ 1. When a mock objects is destructed, Google Mock automatically verifies that all expectations on it have been satisfied.
+
+Here is an example:
+```
+using ::testing::Return; // #1
+
+TEST(BarTest, DoesThis) {
+ MockFoo foo; // #2
+
+ ON_CALL(foo, GetSize()) // #3
+ .WillByDefault(Return(1));
+ // ... other default actions ...
+
+ EXPECT_CALL(foo, Describe(5)) // #4
+ .Times(3)
+ .WillRepeatedly(Return("Category 5"));
+ // ... other expectations ...
+
+ EXPECT_EQ("good", MyProductionFunction(&foo)); // #5
+} // #6
+```
+
+# Setting Default Actions #
+
+Google Mock has a **built-in default action** for any function that
+returns `void`, `bool`, a numeric value, or a pointer.
+
+To customize the default action for functions with return type `T` globally:
+```
+using ::testing::DefaultValue;
+
+// Sets the default value to be returned. T must be CopyConstructible.
+DefaultValue<T>::Set(value);
+// Sets a factory. Will be invoked on demand. T must be MoveConstructible.
+// T MakeT();
+DefaultValue<T>::SetFactory(&MakeT);
+// ... use the mocks ...
+// Resets the default value.
+DefaultValue<T>::Clear();
+```
+
+To customize the default action for a particular method, use `ON_CALL()`:
+```
+ON_CALL(mock_object, method(matchers))
+ .With(multi_argument_matcher) ?
+ .WillByDefault(action);
+```
+
+# Setting Expectations #
+
+`EXPECT_CALL()` sets **expectations** on a mock method (How will it be
+called? What will it do?):
+```
+EXPECT_CALL(mock_object, method(matchers))
+ .With(multi_argument_matcher) ?
+ .Times(cardinality) ?
+ .InSequence(sequences) *
+ .After(expectations) *
+ .WillOnce(action) *
+ .WillRepeatedly(action) ?
+ .RetiresOnSaturation(); ?
+```
+
+If `Times()` is omitted, the cardinality is assumed to be:
+
+ * `Times(1)` when there is neither `WillOnce()` nor `WillRepeatedly()`;
+ * `Times(n)` when there are `n WillOnce()`s but no `WillRepeatedly()`, where `n` >= 1; or
+ * `Times(AtLeast(n))` when there are `n WillOnce()`s and a `WillRepeatedly()`, where `n` >= 0.
+
+A method with no `EXPECT_CALL()` is free to be invoked _any number of times_, and the default action will be taken each time.
+
+# Matchers #
+
+A **matcher** matches a _single_ argument. You can use it inside
+`ON_CALL()` or `EXPECT_CALL()`, or use it to validate a value
+directly:
+
+| `EXPECT_THAT(value, matcher)` | Asserts that `value` matches `matcher`. |
+|:------------------------------|:----------------------------------------|
+| `ASSERT_THAT(value, matcher)` | The same as `EXPECT_THAT(value, matcher)`, except that it generates a **fatal** failure. |
+
+Built-in matchers (where `argument` is the function argument) are
+divided into several categories:
+
+## Wildcard ##
+|`_`|`argument` can be any value of the correct type.|
+|:--|:-----------------------------------------------|
+|`A<type>()` or `An<type>()`|`argument` can be any value of type `type`. |
+
+## Generic Comparison ##
+
+|`Eq(value)` or `value`|`argument == value`|
+|:---------------------|:------------------|
+|`Ge(value)` |`argument >= value`|
+|`Gt(value)` |`argument > value` |
+|`Le(value)` |`argument <= value`|
+|`Lt(value)` |`argument < value` |
+|`Ne(value)` |`argument != value`|
+|`IsNull()` |`argument` is a `NULL` pointer (raw or smart).|
+|`NotNull()` |`argument` is a non-null pointer (raw or smart).|
+|`VariantWith<T>(m)` |`argument` is `variant<>` that holds the alternative of
+type T with a value matching `m`.|
+|`Ref(variable)` |`argument` is a reference to `variable`.|
+|`TypedEq<type>(value)`|`argument` has type `type` and is equal to `value`. You may need to use this instead of `Eq(value)` when the mock function is overloaded.|
+
+Except `Ref()`, these matchers make a _copy_ of `value` in case it's
+modified or destructed later. If the compiler complains that `value`
+doesn't have a public copy constructor, try wrap it in `ByRef()`,
+e.g. `Eq(ByRef(non_copyable_value))`. If you do that, make sure
+`non_copyable_value` is not changed afterwards, or the meaning of your
+matcher will be changed.
+
+## Floating-Point Matchers ##
+
+|`DoubleEq(a_double)`|`argument` is a `double` value approximately equal to `a_double`, treating two NaNs as unequal.|
+|:-------------------|:----------------------------------------------------------------------------------------------|
+|`FloatEq(a_float)` |`argument` is a `float` value approximately equal to `a_float`, treating two NaNs as unequal. |
+|`NanSensitiveDoubleEq(a_double)`|`argument` is a `double` value approximately equal to `a_double`, treating two NaNs as equal. |
+|`NanSensitiveFloatEq(a_float)`|`argument` is a `float` value approximately equal to `a_float`, treating two NaNs as equal. |
+
+The above matchers use ULP-based comparison (the same as used in
+[Google Test](../../googletest/)). They
+automatically pick a reasonable error bound based on the absolute
+value of the expected value. `DoubleEq()` and `FloatEq()` conform to
+the IEEE standard, which requires comparing two NaNs for equality to
+return false. The `NanSensitive*` version instead treats two NaNs as
+equal, which is often what a user wants.
+
+|`DoubleNear(a_double, max_abs_error)`|`argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as unequal.|
+|:------------------------------------|:--------------------------------------------------------------------------------------------------------------------|
+|`FloatNear(a_float, max_abs_error)` |`argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as unequal. |
+|`NanSensitiveDoubleNear(a_double, max_abs_error)`|`argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
+|`NanSensitiveFloatNear(a_float, max_abs_error)`|`argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
+
+## String Matchers ##
+
+The `argument` can be either a C string or a C++ string object:
+
+|`ContainsRegex(string)`|`argument` matches the given regular expression.|
+|:----------------------|:-----------------------------------------------|
+|`EndsWith(suffix)` |`argument` ends with string `suffix`. |
+|`HasSubstr(string)` |`argument` contains `string` as a sub-string. |
+|`MatchesRegex(string)` |`argument` matches the given regular expression with the match starting at the first character and ending at the last character.|
+|`StartsWith(prefix)` |`argument` starts with string `prefix`. |
+|`StrCaseEq(string)` |`argument` is equal to `string`, ignoring case. |
+|`StrCaseNe(string)` |`argument` is not equal to `string`, ignoring case.|
+|`StrEq(string)` |`argument` is equal to `string`. |
+|`StrNe(string)` |`argument` is not equal to `string`. |
+
+`ContainsRegex()` and `MatchesRegex()` use the regular expression
+syntax defined
+[here](../../googletest/docs/AdvancedGuide.md#regular-expression-syntax).
+`StrCaseEq()`, `StrCaseNe()`, `StrEq()`, and `StrNe()` work for wide
+strings as well.
+
+## Container Matchers ##
+
+Most STL-style containers support `==`, so you can use
+`Eq(expected_container)` or simply `expected_container` to match a
+container exactly. If you want to write the elements in-line,
+match them more flexibly, or get more informative messages, you can use:
+
+| `ContainerEq(container)` | The same as `Eq(container)` except that the failure message also includes which elements are in one container but not the other. |
+|:-------------------------|:---------------------------------------------------------------------------------------------------------------------------------|
+| `Contains(e)` | `argument` contains an element that matches `e`, which can be either a value or a matcher. |
+| `Each(e)` | `argument` is a container where _every_ element matches `e`, which can be either a value or a matcher. |
+| `ElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, where the i-th element matches `ei`, which can be a value or a matcher. 0 to 10 arguments are allowed. |
+| `ElementsAreArray({ e0, e1, ..., en })`, `ElementsAreArray(array)`, or `ElementsAreArray(array, count)` | The same as `ElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, or C-style array. |
+| `IsEmpty()` | `argument` is an empty container (`container.empty()`). |
+| `Pointwise(m, container)` | `argument` contains the same number of elements as in `container`, and for all i, (the i-th element in `argument`, the i-th element in `container`) match `m`, which is a matcher on 2-tuples. E.g. `Pointwise(Le(), upper_bounds)` verifies that each element in `argument` doesn't exceed the corresponding element in `upper_bounds`. See more detail below. |
+| `SizeIs(m)` | `argument` is a container whose size matches `m`. E.g. `SizeIs(2)` or `SizeIs(Lt(2))`. |
+| `UnorderedElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, and under some permutation each element matches an `ei` (for a different `i`), which can be a value or a matcher. 0 to 10 arguments are allowed. |
+| `UnorderedElementsAreArray({ e0, e1, ..., en })`, `UnorderedElementsAreArray(array)`, or `UnorderedElementsAreArray(array, count)` | The same as `UnorderedElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, or C-style array. |
+| `WhenSorted(m)` | When `argument` is sorted using the `<` operator, it matches container matcher `m`. E.g. `WhenSorted(ElementsAre(1, 2, 3))` verifies that `argument` contains elements `1`, `2`, and `3`, ignoring order. |
+| `WhenSortedBy(comparator, m)` | The same as `WhenSorted(m)`, except that the given comparator instead of `<` is used to sort `argument`. E.g. `WhenSortedBy(std::greater<int>(), ElementsAre(3, 2, 1))`. |
+
+Notes:
+
+ * These matchers can also match:
+ 1. a native array passed by reference (e.g. in `Foo(const int (&a)[5])`), and
+ 1. an array passed as a pointer and a count (e.g. in `Bar(const T* buffer, int len)` -- see [Multi-argument Matchers](#Multiargument_Matchers.md)).
+ * The array being matched may be multi-dimensional (i.e. its elements can be arrays).
+ * `m` in `Pointwise(m, ...)` should be a matcher for `::testing::tuple<T, U>` where `T` and `U` are the element type of the actual container and the expected container, respectively. For example, to compare two `Foo` containers where `Foo` doesn't support `operator==` but has an `Equals()` method, one might write:
+
+```
+using ::testing::get;
+MATCHER(FooEq, "") {
+ return get<0>(arg).Equals(get<1>(arg));
+}
+...
+EXPECT_THAT(actual_foos, Pointwise(FooEq(), expected_foos));
+```
+
+## Member Matchers ##
+
+|`Field(&class::field, m)`|`argument.field` (or `argument->field` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_.|
+|:------------------------|:---------------------------------------------------------------------------------------------------------------------------------------------|
+|`Key(e)` |`argument.first` matches `e`, which can be either a value or a matcher. E.g. `Contains(Key(Le(5)))` can verify that a `map` contains a key `<= 5`.|
+|`Pair(m1, m2)` |`argument` is an `std::pair` whose `first` field matches `m1` and `second` field matches `m2`. |
+|`Property(&class::property, m)`|`argument.property()` (or `argument->property()` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_.|
+
+## Matching the Result of a Function or Functor ##
+
+|`ResultOf(f, m)`|`f(argument)` matches matcher `m`, where `f` is a function or functor.|
+|:---------------|:---------------------------------------------------------------------|
+
+## Pointer Matchers ##
+
+|`Pointee(m)`|`argument` (either a smart pointer or a raw pointer) points to a value that matches matcher `m`.|
+|:-----------|:-----------------------------------------------------------------------------------------------|
+|`WhenDynamicCastTo<T>(m)`| when `argument` is passed through `dynamic_cast<T>()`, it matches matcher `m`. |
+
+## Multiargument Matchers ##
+
+Technically, all matchers match a _single_ value. A "multi-argument"
+matcher is just one that matches a _tuple_. The following matchers can
+be used to match a tuple `(x, y)`:
+
+|`Eq()`|`x == y`|
+|:-----|:-------|
+|`Ge()`|`x >= y`|
+|`Gt()`|`x > y` |
+|`Le()`|`x <= y`|
+|`Lt()`|`x < y` |
+|`Ne()`|`x != y`|
+
+You can use the following selectors to pick a subset of the arguments
+(or reorder them) to participate in the matching:
+
+|`AllArgs(m)`|Equivalent to `m`. Useful as syntactic sugar in `.With(AllArgs(m))`.|
+|:-----------|:-------------------------------------------------------------------|
+|`Args<N1, N2, ..., Nk>(m)`|The tuple of the `k` selected (using 0-based indices) arguments matches `m`, e.g. `Args<1, 2>(Eq())`.|
+
+## Composite Matchers ##
+
+You can make a matcher from one or more other matchers:
+
+|`AllOf(m1, m2, ..., mn)`|`argument` matches all of the matchers `m1` to `mn`.|
+|:-----------------------|:---------------------------------------------------|
+|`AnyOf(m1, m2, ..., mn)`|`argument` matches at least one of the matchers `m1` to `mn`.|
+|`Not(m)` |`argument` doesn't match matcher `m`. |
+
+## Adapters for Matchers ##
+
+|`MatcherCast<T>(m)`|casts matcher `m` to type `Matcher<T>`.|
+|:------------------|:--------------------------------------|
+|`SafeMatcherCast<T>(m)`| [safely casts](CookBook.md#casting-matchers) matcher `m` to type `Matcher<T>`. |
+|`Truly(predicate)` |`predicate(argument)` returns something considered by C++ to be true, where `predicate` is a function or functor.|
+
+## Matchers as Predicates ##
+
+|`Matches(m)(value)`|evaluates to `true` if `value` matches `m`. You can use `Matches(m)` alone as a unary functor.|
+|:------------------|:---------------------------------------------------------------------------------------------|
+|`ExplainMatchResult(m, value, result_listener)`|evaluates to `true` if `value` matches `m`, explaining the result to `result_listener`. |
+|`Value(value, m)` |evaluates to `true` if `value` matches `m`. |
+
+## Defining Matchers ##
+
+| `MATCHER(IsEven, "") { return (arg % 2) == 0; }` | Defines a matcher `IsEven()` to match an even number. |
+|:-------------------------------------------------|:------------------------------------------------------|
+| `MATCHER_P(IsDivisibleBy, n, "") { *result_listener << "where the remainder is " << (arg % n); return (arg % n) == 0; }` | Defines a macher `IsDivisibleBy(n)` to match a number divisible by `n`. |
+| `MATCHER_P2(IsBetween, a, b, std::string(negation ? "isn't" : "is") + " between " + PrintToString(a) + " and " + PrintToString(b)) { return a <= arg && arg <= b; }` | Defines a matcher `IsBetween(a, b)` to match a value in the range [`a`, `b`]. |
+
+**Notes:**
+
+ 1. The `MATCHER*` macros cannot be used inside a function or class.
+ 1. The matcher body must be _purely functional_ (i.e. it cannot have any side effect, and the result must not depend on anything other than the value being matched and the matcher parameters).
+ 1. You can use `PrintToString(x)` to convert a value `x` of any type to a string.
+
+## Matchers as Test Assertions ##
+
+|`ASSERT_THAT(expression, m)`|Generates a [fatal failure](../../googletest/docs/Primer.md#assertions) if the value of `expression` doesn't match matcher `m`.|
+|:---------------------------|:----------------------------------------------------------------------------------------------------------------------------------------------|
+|`EXPECT_THAT(expression, m)`|Generates a non-fatal failure if the value of `expression` doesn't match matcher `m`. |
+
+# Actions #
+
+**Actions** specify what a mock function should do when invoked.
+
+## Returning a Value ##
+
+|`Return()`|Return from a `void` mock function.|
+|:---------|:----------------------------------|
+|`Return(value)`|Return `value`. If the type of `value` is different to the mock function's return type, `value` is converted to the latter type <i>at the time the expectation is set</i>, not when the action is executed.|
+|`ReturnArg<N>()`|Return the `N`-th (0-based) argument.|
+|`ReturnNew<T>(a1, ..., ak)`|Return `new T(a1, ..., ak)`; a different object is created each time.|
+|`ReturnNull()`|Return a null pointer. |
+|`ReturnPointee(ptr)`|Return the value pointed to by `ptr`.|
+|`ReturnRef(variable)`|Return a reference to `variable`. |
+|`ReturnRefOfCopy(value)`|Return a reference to a copy of `value`; the copy lives as long as the action.|
+
+## Side Effects ##
+
+|`Assign(&variable, value)`|Assign `value` to variable.|
+|:-------------------------|:--------------------------|
+| `DeleteArg<N>()` | Delete the `N`-th (0-based) argument, which must be a pointer. |
+| `SaveArg<N>(pointer)` | Save the `N`-th (0-based) argument to `*pointer`. |
+| `SaveArgPointee<N>(pointer)` | Save the value pointed to by the `N`-th (0-based) argument to `*pointer`. |
+| `SetArgReferee<N>(value)` | Assign value to the variable referenced by the `N`-th (0-based) argument. |
+|`SetArgPointee<N>(value)` |Assign `value` to the variable pointed by the `N`-th (0-based) argument.|
+|`SetArgumentPointee<N>(value)`|Same as `SetArgPointee<N>(value)`. Deprecated. Will be removed in v1.7.0.|
+|`SetArrayArgument<N>(first, last)`|Copies the elements in source range [`first`, `last`) to the array pointed to by the `N`-th (0-based) argument, which can be either a pointer or an iterator. The action does not take ownership of the elements in the source range.|
+|`SetErrnoAndReturn(error, value)`|Set `errno` to `error` and return `value`.|
+|`Throw(exception)` |Throws the given exception, which can be any copyable value. Available since v1.1.0.|
+
+## Using a Function or a Functor as an Action ##
+
+|`Invoke(f)`|Invoke `f` with the arguments passed to the mock function, where `f` can be a global/static function or a functor.|
+|:----------|:-----------------------------------------------------------------------------------------------------------------|
+|`Invoke(object_pointer, &class::method)`|Invoke the {method on the object with the arguments passed to the mock function. |
+|`InvokeWithoutArgs(f)`|Invoke `f`, which can be a global/static function or a functor. `f` must take no arguments. |
+|`InvokeWithoutArgs(object_pointer, &class::method)`|Invoke the method on the object, which takes no arguments. |
+|`InvokeArgument<N>(arg1, arg2, ..., argk)`|Invoke the mock function's `N`-th (0-based) argument, which must be a function or a functor, with the `k` arguments.|
+
+The return value of the invoked function is used as the return value
+of the action.
+
+When defining a function or functor to be used with `Invoke*()`, you can declare any unused parameters as `Unused`:
+```
+ double Distance(Unused, double x, double y) { return sqrt(x*x + y*y); }
+ ...
+ EXPECT_CALL(mock, Foo("Hi", _, _)).WillOnce(Invoke(Distance));
+```
+
+In `InvokeArgument<N>(...)`, if an argument needs to be passed by reference, wrap it inside `ByRef()`. For example,
+```
+ InvokeArgument<2>(5, string("Hi"), ByRef(foo))
+```
+calls the mock function's #2 argument, passing to it `5` and `string("Hi")` by value, and `foo` by reference.
+
+## Default Action ##
+
+|`DoDefault()`|Do the default action (specified by `ON_CALL()` or the built-in one).|
+|:------------|:--------------------------------------------------------------------|
+
+**Note:** due to technical reasons, `DoDefault()` cannot be used inside a composite action - trying to do so will result in a run-time error.
+
+## Composite Actions ##
+
+|`DoAll(a1, a2, ..., an)`|Do all actions `a1` to `an` and return the result of `an` in each invocation. The first `n - 1` sub-actions must return void. |
+|:-----------------------|:-----------------------------------------------------------------------------------------------------------------------------|
+|`IgnoreResult(a)` |Perform action `a` and ignore its result. `a` must not return void. |
+|`WithArg<N>(a)` |Pass the `N`-th (0-based) argument of the mock function to action `a` and perform it. |
+|`WithArgs<N1, N2, ..., Nk>(a)`|Pass the selected (0-based) arguments of the mock function to action `a` and perform it. |
+|`WithoutArgs(a)` |Perform action `a` without any arguments. |
+
+## Defining Actions ##
+
+| `ACTION(Sum) { return arg0 + arg1; }` | Defines an action `Sum()` to return the sum of the mock function's argument #0 and #1. |
+|:--------------------------------------|:---------------------------------------------------------------------------------------|
+| `ACTION_P(Plus, n) { return arg0 + n; }` | Defines an action `Plus(n)` to return the sum of the mock function's argument #0 and `n`. |
+| `ACTION_Pk(Foo, p1, ..., pk) { statements; }` | Defines a parameterized action `Foo(p1, ..., pk)` to execute the given `statements`. |
+
+The `ACTION*` macros cannot be used inside a function or class.
+
+# Cardinalities #
+
+These are used in `Times()` to specify how many times a mock function will be called:
+
+|`AnyNumber()`|The function can be called any number of times.|
+|:------------|:----------------------------------------------|
+|`AtLeast(n)` |The call is expected at least `n` times. |
+|`AtMost(n)` |The call is expected at most `n` times. |
+|`Between(m, n)`|The call is expected between `m` and `n` (inclusive) times.|
+|`Exactly(n) or n`|The call is expected exactly `n` times. In particular, the call should never happen when `n` is 0.|
+
+# Expectation Order #
+
+By default, the expectations can be matched in _any_ order. If some
+or all expectations must be matched in a given order, there are two
+ways to specify it. They can be used either independently or
+together.
+
+## The After Clause ##
+
+```
+using ::testing::Expectation;
+...
+Expectation init_x = EXPECT_CALL(foo, InitX());
+Expectation init_y = EXPECT_CALL(foo, InitY());
+EXPECT_CALL(foo, Bar())
+ .After(init_x, init_y);
+```
+says that `Bar()` can be called only after both `InitX()` and
+`InitY()` have been called.
+
+If you don't know how many pre-requisites an expectation has when you
+write it, you can use an `ExpectationSet` to collect them:
+
+```
+using ::testing::ExpectationSet;
+...
+ExpectationSet all_inits;
+for (int i = 0; i < element_count; i++) {
+ all_inits += EXPECT_CALL(foo, InitElement(i));
+}
+EXPECT_CALL(foo, Bar())
+ .After(all_inits);
+```
+says that `Bar()` can be called only after all elements have been
+initialized (but we don't care about which elements get initialized
+before the others).
+
+Modifying an `ExpectationSet` after using it in an `.After()` doesn't
+affect the meaning of the `.After()`.
+
+## Sequences ##
+
+When you have a long chain of sequential expectations, it's easier to
+specify the order using **sequences**, which don't require you to given
+each expectation in the chain a different name. <i>All expected<br>
+calls</i> in the same sequence must occur in the order they are
+specified.
+
+```
+using ::testing::Sequence;
+Sequence s1, s2;
+...
+EXPECT_CALL(foo, Reset())
+ .InSequence(s1, s2)
+ .WillOnce(Return(true));
+EXPECT_CALL(foo, GetSize())
+ .InSequence(s1)
+ .WillOnce(Return(1));
+EXPECT_CALL(foo, Describe(A<const char*>()))
+ .InSequence(s2)
+ .WillOnce(Return("dummy"));
+```
+says that `Reset()` must be called before _both_ `GetSize()` _and_
+`Describe()`, and the latter two can occur in any order.
+
+To put many expectations in a sequence conveniently:
+```
+using ::testing::InSequence;
+{
+ InSequence dummy;
+
+ EXPECT_CALL(...)...;
+ EXPECT_CALL(...)...;
+ ...
+ EXPECT_CALL(...)...;
+}
+```
+says that all expected calls in the scope of `dummy` must occur in
+strict order. The name `dummy` is irrelevant.)
+
+# Verifying and Resetting a Mock #
+
+Google Mock will verify the expectations on a mock object when it is destructed, or you can do it earlier:
+```
+using ::testing::Mock;
+...
+// Verifies and removes the expectations on mock_obj;
+// returns true iff successful.
+Mock::VerifyAndClearExpectations(&mock_obj);
+...
+// Verifies and removes the expectations on mock_obj;
+// also removes the default actions set by ON_CALL();
+// returns true iff successful.
+Mock::VerifyAndClear(&mock_obj);
+```
+
+You can also tell Google Mock that a mock object can be leaked and doesn't
+need to be verified:
+```
+Mock::AllowLeak(&mock_obj);
+```
+
+# Mock Classes #
+
+Google Mock defines a convenient mock class template
+```
+class MockFunction<R(A1, ..., An)> {
+ public:
+ MOCK_METHODn(Call, R(A1, ..., An));
+};
+```
+See this [recipe](CookBook.md#using-check-points) for one application of it.
+
+# Flags #
+
+| `--gmock_catch_leaked_mocks=0` | Don't report leaked mock objects as failures. |
+|:-------------------------------|:----------------------------------------------|
+| `--gmock_verbose=LEVEL` | Sets the default verbosity level (`info`, `warning`, or `error`) of Google Mock messages. |

+
+
+You can find recipes for using Google Mock here. If you haven't yet,
+please read the [ForDummies](ForDummies.md) document first to make sure you understand
+the basics.
+
+**Note:** Google Mock lives in the `testing` name space. For
+readability, it is recommended to write `using ::testing::Foo;` once in
+your file before using the name `Foo` defined by Google Mock. We omit
+such `using` statements in this page for brevity, but you should do it
+in your own code.
+
+# Creating Mock Classes #
+
+## Mocking Private or Protected Methods ##
+
+You must always put a mock method definition (`MOCK_METHOD*`) in a
+`public:` section of the mock class, regardless of the method being
+mocked being `public`, `protected`, or `private` in the base class.
+This allows `ON_CALL` and `EXPECT_CALL` to reference the mock function
+from outside of the mock class. (Yes, C++ allows a subclass to specify
+a different access level than the base class on a virtual function.)
+Example:
+
+```
+class Foo {
+ public:
+ ...
+ virtual bool Transform(Gadget* g) = 0;
+
+ protected:
+ virtual void Resume();
+
+ private:
+ virtual int GetTimeOut();
+};
+
+class MockFoo : public Foo {
+ public:
+ ...
+ MOCK_METHOD1(Transform, bool(Gadget* g));
+
+ // The following must be in the public section, even though the
+ // methods are protected or private in the base class.
+ MOCK_METHOD0(Resume, void());
+ MOCK_METHOD0(GetTimeOut, int());
+};
+```
+
+## Mocking Overloaded Methods ##
+
+You can mock overloaded functions as usual. No special attention is required:
+
+```
+class Foo {
+ ...
+
+ // Must be virtual as we'll inherit from Foo.
+ virtual ~Foo();
+
+ // Overloaded on the types and/or numbers of arguments.
+ virtual int Add(Element x);
+ virtual int Add(int times, Element x);
+
+ // Overloaded on the const-ness of this object.
+ virtual Bar& GetBar();
+ virtual const Bar& GetBar() const;
+};
+
+class MockFoo : public Foo {
+ ...
+ MOCK_METHOD1(Add, int(Element x));
+ MOCK_METHOD2(Add, int(int times, Element x);
+
+ MOCK_METHOD0(GetBar, Bar&());
+ MOCK_CONST_METHOD0(GetBar, const Bar&());
+};
+```
+
+**Note:** if you don't mock all versions of the overloaded method, the
+compiler will give you a warning about some methods in the base class
+being hidden. To fix that, use `using` to bring them in scope:
+
+```
+class MockFoo : public Foo {
+ ...
+ using Foo::Add;
+ MOCK_METHOD1(Add, int(Element x));
+ // We don't want to mock int Add(int times, Element x);
+ ...
+};
+```
+
+## Mocking Class Templates ##
+
+To mock a class template, append `_T` to the `MOCK_*` macros:
+
+```
+template <typename Elem>
+class StackInterface {
+ ...
+ // Must be virtual as we'll inherit from StackInterface.
+ virtual ~StackInterface();
+
+ virtual int GetSize() const = 0;
+ virtual void Push(const Elem& x) = 0;
+};
+
+template <typename Elem>
+class MockStack : public StackInterface<Elem> {
+ ...
+ MOCK_CONST_METHOD0_T(GetSize, int());
+ MOCK_METHOD1_T(Push, void(const Elem& x));
+};
+```
+
+## Mocking Nonvirtual Methods ##
+
+Google Mock can mock non-virtual functions to be used in what we call _hi-perf
+dependency injection_.
+
+In this case, instead of sharing a common base class with the real
+class, your mock class will be _unrelated_ to the real class, but
+contain methods with the same signatures. The syntax for mocking
+non-virtual methods is the _same_ as mocking virtual methods:
+
+```
+// A simple packet stream class. None of its members is virtual.
+class ConcretePacketStream {
+ public:
+ void AppendPacket(Packet* new_packet);
+ const Packet* GetPacket(size_t packet_number) const;
+ size_t NumberOfPackets() const;
+ ...
+};
+
+// A mock packet stream class. It inherits from no other, but defines
+// GetPacket() and NumberOfPackets().
+class MockPacketStream {
+ public:
+ MOCK_CONST_METHOD1(GetPacket, const Packet*(size_t packet_number));
+ MOCK_CONST_METHOD0(NumberOfPackets, size_t());
+ ...
+};
+```
+
+Note that the mock class doesn't define `AppendPacket()`, unlike the
+real class. That's fine as long as the test doesn't need to call it.
+
+Next, you need a way to say that you want to use
+`ConcretePacketStream` in production code and to use `MockPacketStream`
+in tests. Since the functions are not virtual and the two classes are
+unrelated, you must specify your choice at _compile time_ (as opposed
+to run time).
+
+One way to do it is to templatize your code that needs to use a packet
+stream. More specifically, you will give your code a template type
+argument for the type of the packet stream. In production, you will
+instantiate your template with `ConcretePacketStream` as the type
+argument. In tests, you will instantiate the same template with
+`MockPacketStream`. For example, you may write:
+
+```
+template <class PacketStream>
+void CreateConnection(PacketStream* stream) { ... }
+
+template <class PacketStream>
+class PacketReader {
+ public:
+ void ReadPackets(PacketStream* stream, size_t packet_num);
+};
+```
+
+Then you can use `CreateConnection<ConcretePacketStream>()` and
+`PacketReader<ConcretePacketStream>` in production code, and use
+`CreateConnection<MockPacketStream>()` and
+`PacketReader<MockPacketStream>` in tests.
+
+```
+ MockPacketStream mock_stream;
+ EXPECT_CALL(mock_stream, ...)...;
+ .. set more expectations on mock_stream ...
+ PacketReader<MockPacketStream> reader(&mock_stream);
+ ... exercise reader ...
+```
+
+## Mocking Free Functions ##
+
+It's possible to use Google Mock to mock a free function (i.e. a
+C-style function or a static method). You just need to rewrite your
+code to use an interface (abstract class).
+
+Instead of calling a free function (say, `OpenFile`) directly,
+introduce an interface for it and have a concrete subclass that calls
+the free function:
+
+```
+class FileInterface {
+ public:
+ ...
+ virtual bool Open(const char* path, const char* mode) = 0;
+};
+
+class File : public FileInterface {
+ public:
+ ...
+ virtual bool Open(const char* path, const char* mode) {
+ return OpenFile(path, mode);
+ }
+};
+```
+
+Your code should talk to `FileInterface` to open a file. Now it's
+easy to mock out the function.
+
+This may seem much hassle, but in practice you often have multiple
+related functions that you can put in the same interface, so the
+per-function syntactic overhead will be much lower.
+
+If you are concerned about the performance overhead incurred by
+virtual functions, and profiling confirms your concern, you can
+combine this with the recipe for [mocking non-virtual methods](#mocking-nonvirtual-methods).
+
+## The Nice, the Strict, and the Naggy ##
+
+If a mock method has no `EXPECT_CALL` spec but is called, Google Mock
+will print a warning about the "uninteresting call". The rationale is:
+
+ * New methods may be added to an interface after a test is written. We shouldn't fail a test just because a method it doesn't know about is called.
+ * However, this may also mean there's a bug in the test, so Google Mock shouldn't be silent either. If the user believes these calls are harmless, they can add an `EXPECT_CALL()` to suppress the warning.
+
+However, sometimes you may want to suppress all "uninteresting call"
+warnings, while sometimes you may want the opposite, i.e. to treat all
+of them as errors. Google Mock lets you make the decision on a
+per-mock-object basis.
+
+Suppose your test uses a mock class `MockFoo`:
+
+```
+TEST(...) {
+ MockFoo mock_foo;
+ EXPECT_CALL(mock_foo, DoThis());
+ ... code that uses mock_foo ...
+}
+```
+
+If a method of `mock_foo` other than `DoThis()` is called, it will be
+reported by Google Mock as a warning. However, if you rewrite your
+test to use `NiceMock<MockFoo>` instead, the warning will be gone,
+resulting in a cleaner test output:
+
+```
+using ::testing::NiceMock;
+
+TEST(...) {
+ NiceMock<MockFoo> mock_foo;
+ EXPECT_CALL(mock_foo, DoThis());
+ ... code that uses mock_foo ...
+}
+```
+
+`NiceMock<MockFoo>` is a subclass of `MockFoo`, so it can be used
+wherever `MockFoo` is accepted.
+
+It also works if `MockFoo`'s constructor takes some arguments, as
+`NiceMock<MockFoo>` "inherits" `MockFoo`'s constructors:
+
+```
+using ::testing::NiceMock;
+
+TEST(...) {
+ NiceMock<MockFoo> mock_foo(5, "hi"); // Calls MockFoo(5, "hi").
+ EXPECT_CALL(mock_foo, DoThis());
+ ... code that uses mock_foo ...
+}
+```
+
+The usage of `StrictMock` is similar, except that it makes all
+uninteresting calls failures:
+
+```
+using ::testing::StrictMock;
+
+TEST(...) {
+ StrictMock<MockFoo> mock_foo;
+ EXPECT_CALL(mock_foo, DoThis());
+ ... code that uses mock_foo ...
+
+ // The test will fail if a method of mock_foo other than DoThis()
+ // is called.
+}
+```
+
+There are some caveats though (I don't like them just as much as the
+next guy, but sadly they are side effects of C++'s limitations):
+
+ 1. `NiceMock<MockFoo>` and `StrictMock<MockFoo>` only work for mock methods defined using the `MOCK_METHOD*` family of macros **directly** in the `MockFoo` class. If a mock method is defined in a **base class** of `MockFoo`, the "nice" or "strict" modifier may not affect it, depending on the compiler. In particular, nesting `NiceMock` and `StrictMock` (e.g. `NiceMock<StrictMock<MockFoo> >`) is **not** supported.
+ 1. The constructors of the base mock (`MockFoo`) cannot have arguments passed by non-const reference, which happens to be banned by the [Google C++ style guide](https://google.github.io/styleguide/cppguide.html).
+ 1. During the constructor or destructor of `MockFoo`, the mock object is _not_ nice or strict. This may cause surprises if the constructor or destructor calls a mock method on `this` object. (This behavior, however, is consistent with C++'s general rule: if a constructor or destructor calls a virtual method of `this` object, that method is treated as non-virtual. In other words, to the base class's constructor or destructor, `this` object behaves like an instance of the base class, not the derived class. This rule is required for safety. Otherwise a base constructor may use members of a derived class before they are initialized, or a base destructor may use members of a derived class after they have been destroyed.)
+
+Finally, you should be **very cautious** about when to use naggy or strict mocks, as they tend to make tests more brittle and harder to maintain. When you refactor your code without changing its externally visible behavior, ideally you should't need to update any tests. If your code interacts with a naggy mock, however, you may start to get spammed with warnings as the result of your change. Worse, if your code interacts with a strict mock, your tests may start to fail and you'll be forced to fix them. Our general recommendation is to use nice mocks (not yet the default) most of the time, use naggy mocks (the current default) when developing or debugging tests, and use strict mocks only as the last resort.
+
+## Simplifying the Interface without Breaking Existing Code ##
+
+Sometimes a method has a long list of arguments that is mostly
+uninteresting. For example,
+
+```
+class LogSink {
+ public:
+ ...
+ virtual void send(LogSeverity severity, const char* full_filename,
+ const char* base_filename, int line,
+ const struct tm* tm_time,
+ const char* message, size_t message_len) = 0;
+};
+```
+
+This method's argument list is lengthy and hard to work with (let's
+say that the `message` argument is not even 0-terminated). If we mock
+it as is, using the mock will be awkward. If, however, we try to
+simplify this interface, we'll need to fix all clients depending on
+it, which is often infeasible.
+
+The trick is to re-dispatch the method in the mock class:
+
+```
+class ScopedMockLog : public LogSink {
+ public:
+ ...
+ virtual void send(LogSeverity severity, const char* full_filename,
+ const char* base_filename, int line, const tm* tm_time,
+ const char* message, size_t message_len) {
+ // We are only interested in the log severity, full file name, and
+ // log message.
+ Log(severity, full_filename, std::string(message, message_len));
+ }
+
+ // Implements the mock method:
+ //
+ // void Log(LogSeverity severity,
+ // const string& file_path,
+ // const string& message);
+ MOCK_METHOD3(Log, void(LogSeverity severity, const string& file_path,
+ const string& message));
+};
+```
+
+By defining a new mock method with a trimmed argument list, we make
+the mock class much more user-friendly.
+
+## Alternative to Mocking Concrete Classes ##
+
+Often you may find yourself using classes that don't implement
+interfaces. In order to test your code that uses such a class (let's
+call it `Concrete`), you may be tempted to make the methods of
+`Concrete` virtual and then mock it.
+
+Try not to do that.
+
+Making a non-virtual function virtual is a big decision. It creates an
+extension point where subclasses can tweak your class' behavior. This
+weakens your control on the class because now it's harder to maintain
+the class' invariants. You should make a function virtual only when
+there is a valid reason for a subclass to override it.
+
+Mocking concrete classes directly is problematic as it creates a tight
+coupling between the class and the tests - any small change in the
+class may invalidate your tests and make test maintenance a pain.
+
+To avoid such problems, many programmers have been practicing "coding
+to interfaces": instead of talking to the `Concrete` class, your code
+would define an interface and talk to it. Then you implement that
+interface as an adaptor on top of `Concrete`. In tests, you can easily
+mock that interface to observe how your code is doing.
+
+This technique incurs some overhead:
+
+ * You pay the cost of virtual function calls (usually not a problem).
+ * There is more abstraction for the programmers to learn.
+
+However, it can also bring significant benefits in addition to better
+testability:
+
+ * `Concrete`'s API may not fit your problem domain very well, as you may not be the only client it tries to serve. By designing your own interface, you have a chance to tailor it to your need - you may add higher-level functionalities, rename stuff, etc instead of just trimming the class. This allows you to write your code (user of the interface) in a more natural way, which means it will be more readable, more maintainable, and you'll be more productive.
+ * If `Concrete`'s implementation ever has to change, you don't have to rewrite everywhere it is used. Instead, you can absorb the change in your implementation of the interface, and your other code and tests will be insulated from this change.
+
+Some people worry that if everyone is practicing this technique, they
+will end up writing lots of redundant code. This concern is totally
+understandable. However, there are two reasons why it may not be the
+case:
+
+ * Different projects may need to use `Concrete` in different ways, so the best interfaces for them will be different. Therefore, each of them will have its own domain-specific interface on top of `Concrete`, and they will not be the same code.
+ * If enough projects want to use the same interface, they can always share it, just like they have been sharing `Concrete`. You can check in the interface and the adaptor somewhere near `Concrete` (perhaps in a `contrib` sub-directory) and let many projects use it.
+
+You need to weigh the pros and cons carefully for your particular
+problem, but I'd like to assure you that the Java community has been
+practicing this for a long time and it's a proven effective technique
+applicable in a wide variety of situations. :-)
+
+## Delegating Calls to a Fake ##
+
+Some times you have a non-trivial fake implementation of an
+interface. For example:
+
+```
+class Foo {
+ public:
+ virtual ~Foo() {}
+ virtual char DoThis(int n) = 0;
+ virtual void DoThat(const char* s, int* p) = 0;
+};
+
+class FakeFoo : public Foo {
+ public:
+ virtual char DoThis(int n) {
+ return (n > 0) ? '+' :
+ (n < 0) ? '-' : '0';
+ }
+
+ virtual void DoThat(const char* s, int* p) {
+ *p = strlen(s);
+ }
+};
+```
+
+Now you want to mock this interface such that you can set expectations
+on it. However, you also want to use `FakeFoo` for the default
+behavior, as duplicating it in the mock object is, well, a lot of
+work.
+
+When you define the mock class using Google Mock, you can have it
+delegate its default action to a fake class you already have, using
+this pattern:
+
+```
+using ::testing::_;
+using ::testing::Invoke;
+
+class MockFoo : public Foo {
+ public:
+ // Normal mock method definitions using Google Mock.
+ MOCK_METHOD1(DoThis, char(int n));
+ MOCK_METHOD2(DoThat, void(const char* s, int* p));
+
+ // Delegates the default actions of the methods to a FakeFoo object.
+ // This must be called *before* the custom ON_CALL() statements.
+ void DelegateToFake() {
+ ON_CALL(*this, DoThis(_))
+ .WillByDefault(Invoke(&fake_, &FakeFoo::DoThis));
+ ON_CALL(*this, DoThat(_, _))
+ .WillByDefault(Invoke(&fake_, &FakeFoo::DoThat));
+ }
+ private:
+ FakeFoo fake_; // Keeps an instance of the fake in the mock.
+};
+```
+
+With that, you can use `MockFoo` in your tests as usual. Just remember
+that if you don't explicitly set an action in an `ON_CALL()` or
+`EXPECT_CALL()`, the fake will be called upon to do it:
+
+```
+using ::testing::_;
+
+TEST(AbcTest, Xyz) {
+ MockFoo foo;
+ foo.DelegateToFake(); // Enables the fake for delegation.
+
+ // Put your ON_CALL(foo, ...)s here, if any.
+
+ // No action specified, meaning to use the default action.
+ EXPECT_CALL(foo, DoThis(5));
+ EXPECT_CALL(foo, DoThat(_, _));
+
+ int n = 0;
+ EXPECT_EQ('+', foo.DoThis(5)); // FakeFoo::DoThis() is invoked.
+ foo.DoThat("Hi", &n); // FakeFoo::DoThat() is invoked.
+ EXPECT_EQ(2, n);
+}
+```
+
+**Some tips:**
+
+ * If you want, you can still override the default action by providing your own `ON_CALL()` or using `.WillOnce()` / `.WillRepeatedly()` in `EXPECT_CALL()`.
+ * In `DelegateToFake()`, you only need to delegate the methods whose fake implementation you intend to use.
+ * The general technique discussed here works for overloaded methods, but you'll need to tell the compiler which version you mean. To disambiguate a mock function (the one you specify inside the parentheses of `ON_CALL()`), see the "Selecting Between Overloaded Functions" section on this page; to disambiguate a fake function (the one you place inside `Invoke()`), use a `static_cast` to specify the function's type. For instance, if class `Foo` has methods `char DoThis(int n)` and `bool DoThis(double x) const`, and you want to invoke the latter, you need to write `Invoke(&fake_, static_cast<bool (FakeFoo::*)(double) const>(&FakeFoo::DoThis))` instead of `Invoke(&fake_, &FakeFoo::DoThis)` (The strange-looking thing inside the angled brackets of `static_cast` is the type of a function pointer to the second `DoThis()` method.).
+ * Having to mix a mock and a fake is often a sign of something gone wrong. Perhaps you haven't got used to the interaction-based way of testing yet. Or perhaps your interface is taking on too many roles and should be split up. Therefore, **don't abuse this**. We would only recommend to do it as an intermediate step when you are refactoring your code.
+
+Regarding the tip on mixing a mock and a fake, here's an example on
+why it may be a bad sign: Suppose you have a class `System` for
+low-level system operations. In particular, it does file and I/O
+operations. And suppose you want to test how your code uses `System`
+to do I/O, and you just want the file operations to work normally. If
+you mock out the entire `System` class, you'll have to provide a fake
+implementation for the file operation part, which suggests that
+`System` is taking on too many roles.
+
+Instead, you can define a `FileOps` interface and an `IOOps` interface
+and split `System`'s functionalities into the two. Then you can mock
+`IOOps` without mocking `FileOps`.
+
+## Delegating Calls to a Real Object ##
+
+When using testing doubles (mocks, fakes, stubs, and etc), sometimes
+their behaviors will differ from those of the real objects. This
+difference could be either intentional (as in simulating an error such
+that you can test the error handling code) or unintentional. If your
+mocks have different behaviors than the real objects by mistake, you
+could end up with code that passes the tests but fails in production.
+
+You can use the _delegating-to-real_ technique to ensure that your
+mock has the same behavior as the real object while retaining the
+ability to validate calls. This technique is very similar to the
+delegating-to-fake technique, the difference being that we use a real
+object instead of a fake. Here's an example:
+
+```
+using ::testing::_;
+using ::testing::AtLeast;
+using ::testing::Invoke;
+
+class MockFoo : public Foo {
+ public:
+ MockFoo() {
+ // By default, all calls are delegated to the real object.
+ ON_CALL(*this, DoThis())
+ .WillByDefault(Invoke(&real_, &Foo::DoThis));
+ ON_CALL(*this, DoThat(_))
+ .WillByDefault(Invoke(&real_, &Foo::DoThat));
+ ...
+ }
+ MOCK_METHOD0(DoThis, ...);
+ MOCK_METHOD1(DoThat, ...);
+ ...
+ private:
+ Foo real_;
+};
+...
+
+ MockFoo mock;
+
+ EXPECT_CALL(mock, DoThis())
+ .Times(3);
+ EXPECT_CALL(mock, DoThat("Hi"))
+ .Times(AtLeast(1));
+ ... use mock in test ...
+```
+
+With this, Google Mock will verify that your code made the right calls
+(with the right arguments, in the right order, called the right number
+of times, etc), and a real object will answer the calls (so the
+behavior will be the same as in production). This gives you the best
+of both worlds.
+
+## Delegating Calls to a Parent Class ##
+
+Ideally, you should code to interfaces, whose methods are all pure
+virtual. In reality, sometimes you do need to mock a virtual method
+that is not pure (i.e, it already has an implementation). For example:
+
+```
+class Foo {
+ public:
+ virtual ~Foo();
+
+ virtual void Pure(int n) = 0;
+ virtual int Concrete(const char* str) { ... }
+};
+
+class MockFoo : public Foo {
+ public:
+ // Mocking a pure method.
+ MOCK_METHOD1(Pure, void(int n));
+ // Mocking a concrete method. Foo::Concrete() is shadowed.
+ MOCK_METHOD1(Concrete, int(const char* str));
+};
+```
+
+Sometimes you may want to call `Foo::Concrete()` instead of
+`MockFoo::Concrete()`. Perhaps you want to do it as part of a stub
+action, or perhaps your test doesn't need to mock `Concrete()` at all
+(but it would be oh-so painful to have to define a new mock class
+whenever you don't need to mock one of its methods).
+
+The trick is to leave a back door in your mock class for accessing the
+real methods in the base class:
+
+```
+class MockFoo : public Foo {
+ public:
+ // Mocking a pure method.
+ MOCK_METHOD1(Pure, void(int n));
+ // Mocking a concrete method. Foo::Concrete() is shadowed.
+ MOCK_METHOD1(Concrete, int(const char* str));
+
+ // Use this to call Concrete() defined in Foo.
+ int FooConcrete(const char* str) { return Foo::Concrete(str); }
+};
+```
+
+Now, you can call `Foo::Concrete()` inside an action by:
+
+```
+using ::testing::_;
+using ::testing::Invoke;
+...
+ EXPECT_CALL(foo, Concrete(_))
+ .WillOnce(Invoke(&foo, &MockFoo::FooConcrete));
+```
+
+or tell the mock object that you don't want to mock `Concrete()`:
+
+```
+using ::testing::Invoke;
+...
+ ON_CALL(foo, Concrete(_))
+ .WillByDefault(Invoke(&foo, &MockFoo::FooConcrete));
+```
+
+(Why don't we just write `Invoke(&foo, &Foo::Concrete)`? If you do
+that, `MockFoo::Concrete()` will be called (and cause an infinite
+recursion) since `Foo::Concrete()` is virtual. That's just how C++
+works.)
+
+# Using Matchers #
+
+## Matching Argument Values Exactly ##
+
+You can specify exactly which arguments a mock method is expecting:
+
+```
+using ::testing::Return;
+...
+ EXPECT_CALL(foo, DoThis(5))
+ .WillOnce(Return('a'));
+ EXPECT_CALL(foo, DoThat("Hello", bar));
+```
+
+## Using Simple Matchers ##
+
+You can use matchers to match arguments that have a certain property:
+
+```
+using ::testing::Ge;
+using ::testing::NotNull;
+using ::testing::Return;
+...
+ EXPECT_CALL(foo, DoThis(Ge(5))) // The argument must be >= 5.
+ .WillOnce(Return('a'));
+ EXPECT_CALL(foo, DoThat("Hello", NotNull()));
+ // The second argument must not be NULL.
+```
+
+A frequently used matcher is `_`, which matches anything:
+
+```
+using ::testing::_;
+using ::testing::NotNull;
+...
+ EXPECT_CALL(foo, DoThat(_, NotNull()));
+```
+
+## Combining Matchers ##
+
+You can build complex matchers from existing ones using `AllOf()`,
+`AnyOf()`, and `Not()`:
+
+```
+using ::testing::AllOf;
+using ::testing::Gt;
+using ::testing::HasSubstr;
+using ::testing::Ne;
+using ::testing::Not;
+...
+ // The argument must be > 5 and != 10.
+ EXPECT_CALL(foo, DoThis(AllOf(Gt(5),
+ Ne(10))));
+
+ // The first argument must not contain sub-string "blah".
+ EXPECT_CALL(foo, DoThat(Not(HasSubstr("blah")),
+ NULL));
+```
+
+## Casting Matchers ##
+
+Google Mock matchers are statically typed, meaning that the compiler
+can catch your mistake if you use a matcher of the wrong type (for
+example, if you use `Eq(5)` to match a `string` argument). Good for
+you!
+
+Sometimes, however, you know what you're doing and want the compiler
+to give you some slack. One example is that you have a matcher for
+`long` and the argument you want to match is `int`. While the two
+types aren't exactly the same, there is nothing really wrong with
+using a `Matcher<long>` to match an `int` - after all, we can first
+convert the `int` argument to a `long` before giving it to the
+matcher.
+
+To support this need, Google Mock gives you the
+`SafeMatcherCast<T>(m)` function. It casts a matcher `m` to type
+`Matcher<T>`. To ensure safety, Google Mock checks that (let `U` be the
+type `m` accepts):
+
+ 1. Type `T` can be implicitly cast to type `U`;
+ 1. When both `T` and `U` are built-in arithmetic types (`bool`, integers, and floating-point numbers), the conversion from `T` to `U` is not lossy (in other words, any value representable by `T` can also be represented by `U`); and
+ 1. When `U` is a reference, `T` must also be a reference (as the underlying matcher may be interested in the address of the `U` value).
+
+The code won't compile if any of these conditions aren't met.
+
+Here's one example:
+
+```
+using ::testing::SafeMatcherCast;
+
+// A base class and a child class.
+class Base { ... };
+class Derived : public Base { ... };
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD1(DoThis, void(Derived* derived));
+};
+...
+
+ MockFoo foo;
+ // m is a Matcher<Base*> we got from somewhere.
+ EXPECT_CALL(foo, DoThis(SafeMatcherCast<Derived*>(m)));
+```
+
+If you find `SafeMatcherCast<T>(m)` too limiting, you can use a similar
+function `MatcherCast<T>(m)`. The difference is that `MatcherCast` works
+as long as you can `static_cast` type `T` to type `U`.
+
+`MatcherCast` essentially lets you bypass C++'s type system
+(`static_cast` isn't always safe as it could throw away information,
+for example), so be careful not to misuse/abuse it.
+
+## Selecting Between Overloaded Functions ##
+
+If you expect an overloaded function to be called, the compiler may
+need some help on which overloaded version it is.
+
+To disambiguate functions overloaded on the const-ness of this object,
+use the `Const()` argument wrapper.
+
+```
+using ::testing::ReturnRef;
+
+class MockFoo : public Foo {
+ ...
+ MOCK_METHOD0(GetBar, Bar&());
+ MOCK_CONST_METHOD0(GetBar, const Bar&());
+};
+...
+
+ MockFoo foo;
+ Bar bar1, bar2;
+ EXPECT_CALL(foo, GetBar()) // The non-const GetBar().
+ .WillOnce(ReturnRef(bar1));
+ EXPECT_CALL(Const(foo), GetBar()) // The const GetBar().
+ .WillOnce(ReturnRef(bar2));
+```
+
+(`Const()` is defined by Google Mock and returns a `const` reference
+to its argument.)
+
+To disambiguate overloaded functions with the same number of arguments
+but different argument types, you may need to specify the exact type
+of a matcher, either by wrapping your matcher in `Matcher<type>()`, or
+using a matcher whose type is fixed (`TypedEq<type>`, `An<type>()`,
+etc):
+
+```
+using ::testing::An;
+using ::testing::Lt;
+using ::testing::Matcher;
+using ::testing::TypedEq;
+
+class MockPrinter : public Printer {
+ public:
+ MOCK_METHOD1(Print, void(int n));
+ MOCK_METHOD1(Print, void(char c));
+};
+
+TEST(PrinterTest, Print) {
+ MockPrinter printer;
+
+ EXPECT_CALL(printer, Print(An<int>())); // void Print(int);
+ EXPECT_CALL(printer, Print(Matcher<int>(Lt(5)))); // void Print(int);
+ EXPECT_CALL(printer, Print(TypedEq<char>('a'))); // void Print(char);
+
+ printer.Print(3);
+ printer.Print(6);
+ printer.Print('a');
+}
+```
+
+## Performing Different Actions Based on the Arguments ##
+
+When a mock method is called, the _last_ matching expectation that's
+still active will be selected (think "newer overrides older"). So, you
+can make a method do different things depending on its argument values
+like this:
+
+```
+using ::testing::_;
+using ::testing::Lt;
+using ::testing::Return;
+...
+ // The default case.
+ EXPECT_CALL(foo, DoThis(_))
+ .WillRepeatedly(Return('b'));
+
+ // The more specific case.
+ EXPECT_CALL(foo, DoThis(Lt(5)))
+ .WillRepeatedly(Return('a'));
+```
+
+Now, if `foo.DoThis()` is called with a value less than 5, `'a'` will
+be returned; otherwise `'b'` will be returned.
+
+## Matching Multiple Arguments as a Whole ##
+
+Sometimes it's not enough to match the arguments individually. For
+example, we may want to say that the first argument must be less than
+the second argument. The `With()` clause allows us to match
+all arguments of a mock function as a whole. For example,
+
+```
+using ::testing::_;
+using ::testing::Lt;
+using ::testing::Ne;
+...
+ EXPECT_CALL(foo, InRange(Ne(0), _))
+ .With(Lt());
+```
+
+says that the first argument of `InRange()` must not be 0, and must be
+less than the second argument.
+
+The expression inside `With()` must be a matcher of type
+`Matcher< ::testing::tuple<A1, ..., An> >`, where `A1`, ..., `An` are the
+types of the function arguments.
+
+You can also write `AllArgs(m)` instead of `m` inside `.With()`. The
+two forms are equivalent, but `.With(AllArgs(Lt()))` is more readable
+than `.With(Lt())`.
+
+You can use `Args<k1, ..., kn>(m)` to match the `n` selected arguments
+(as a tuple) against `m`. For example,
+
+```
+using ::testing::_;
+using ::testing::AllOf;
+using ::testing::Args;
+using ::testing::Lt;
+...
+ EXPECT_CALL(foo, Blah(_, _, _))
+ .With(AllOf(Args<0, 1>(Lt()), Args<1, 2>(Lt())));
+```
+
+says that `Blah()` will be called with arguments `x`, `y`, and `z` where
+`x < y < z`.
+
+As a convenience and example, Google Mock provides some matchers for
+2-tuples, including the `Lt()` matcher above. See the [CheatSheet](CheatSheet.md) for
+the complete list.
+
+Note that if you want to pass the arguments to a predicate of your own
+(e.g. `.With(Args<0, 1>(Truly(&MyPredicate)))`), that predicate MUST be
+written to take a `::testing::tuple` as its argument; Google Mock will pass the `n` selected arguments as _one_ single tuple to the predicate.
+
+## Using Matchers as Predicates ##
+
+Have you noticed that a matcher is just a fancy predicate that also
+knows how to describe itself? Many existing algorithms take predicates
+as arguments (e.g. those defined in STL's `<algorithm>` header), and
+it would be a shame if Google Mock matchers are not allowed to
+participate.
+
+Luckily, you can use a matcher where a unary predicate functor is
+expected by wrapping it inside the `Matches()` function. For example,
+
+```
+#include <algorithm>
+#include <vector>
+
+std::vector<int> v;
+...
+// How many elements in v are >= 10?
+const int count = count_if(v.begin(), v.end(), Matches(Ge(10)));
+```
+
+Since you can build complex matchers from simpler ones easily using
+Google Mock, this gives you a way to conveniently construct composite
+predicates (doing the same using STL's `<functional>` header is just
+painful). For example, here's a predicate that's satisfied by any
+number that is >= 0, <= 100, and != 50:
+
+```
+Matches(AllOf(Ge(0), Le(100), Ne(50)))
+```
+
+## Using Matchers in Google Test Assertions ##
+
+Since matchers are basically predicates that also know how to describe
+themselves, there is a way to take advantage of them in
+[Google Test](../../googletest/) assertions. It's
+called `ASSERT_THAT` and `EXPECT_THAT`:
+
+```
+ ASSERT_THAT(value, matcher); // Asserts that value matches matcher.
+ EXPECT_THAT(value, matcher); // The non-fatal version.
+```
+
+For example, in a Google Test test you can write:
+
+```
+#include "gmock/gmock.h"
+
+using ::testing::AllOf;
+using ::testing::Ge;
+using ::testing::Le;
+using ::testing::MatchesRegex;
+using ::testing::StartsWith;
+...
+
+ EXPECT_THAT(Foo(), StartsWith("Hello"));
+ EXPECT_THAT(Bar(), MatchesRegex("Line \\d+"));
+ ASSERT_THAT(Baz(), AllOf(Ge(5), Le(10)));
+```
+
+which (as you can probably guess) executes `Foo()`, `Bar()`, and
+`Baz()`, and verifies that:
+
+ * `Foo()` returns a string that starts with `"Hello"`.
+ * `Bar()` returns a string that matches regular expression `"Line \\d+"`.
+ * `Baz()` returns a number in the range [5, 10].
+
+The nice thing about these macros is that _they read like
+English_. They generate informative messages too. For example, if the
+first `EXPECT_THAT()` above fails, the message will be something like:
+
+```
+Value of: Foo()
+ Actual: "Hi, world!"
+Expected: starts with "Hello"
+```
+
+**Credit:** The idea of `(ASSERT|EXPECT)_THAT` was stolen from the
+[Hamcrest](https://github.com/hamcrest/) project, which adds
+`assertThat()` to JUnit.
+
+## Using Predicates as Matchers ##
+
+Google Mock provides a built-in set of matchers. In case you find them
+lacking, you can use an arbitray unary predicate function or functor
+as a matcher - as long as the predicate accepts a value of the type
+you want. You do this by wrapping the predicate inside the `Truly()`
+function, for example:
+
+```
+using ::testing::Truly;
+
+int IsEven(int n) { return (n % 2) == 0 ? 1 : 0; }
+...
+
+ // Bar() must be called with an even number.
+ EXPECT_CALL(foo, Bar(Truly(IsEven)));
+```
+
+Note that the predicate function / functor doesn't have to return
+`bool`. It works as long as the return value can be used as the
+condition in statement `if (condition) ...`.
+
+## Matching Arguments that Are Not Copyable ##
+
+When you do an `EXPECT_CALL(mock_obj, Foo(bar))`, Google Mock saves
+away a copy of `bar`. When `Foo()` is called later, Google Mock
+compares the argument to `Foo()` with the saved copy of `bar`. This
+way, you don't need to worry about `bar` being modified or destroyed
+after the `EXPECT_CALL()` is executed. The same is true when you use
+matchers like `Eq(bar)`, `Le(bar)`, and so on.
+
+But what if `bar` cannot be copied (i.e. has no copy constructor)? You
+could define your own matcher function and use it with `Truly()`, as
+the previous couple of recipes have shown. Or, you may be able to get
+away from it if you can guarantee that `bar` won't be changed after
+the `EXPECT_CALL()` is executed. Just tell Google Mock that it should
+save a reference to `bar`, instead of a copy of it. Here's how:
+
+```
+using ::testing::Eq;
+using ::testing::ByRef;
+using ::testing::Lt;
+...
+ // Expects that Foo()'s argument == bar.
+ EXPECT_CALL(mock_obj, Foo(Eq(ByRef(bar))));
+
+ // Expects that Foo()'s argument < bar.
+ EXPECT_CALL(mock_obj, Foo(Lt(ByRef(bar))));
+```
+
+Remember: if you do this, don't change `bar` after the
+`EXPECT_CALL()`, or the result is undefined.
+
+## Validating a Member of an Object ##
+
+Often a mock function takes a reference to object as an argument. When
+matching the argument, you may not want to compare the entire object
+against a fixed object, as that may be over-specification. Instead,
+you may need to validate a certain member variable or the result of a
+certain getter method of the object. You can do this with `Field()`
+and `Property()`. More specifically,
+
+```
+Field(&Foo::bar, m)
+```
+
+is a matcher that matches a `Foo` object whose `bar` member variable
+satisfies matcher `m`.
+
+```
+Property(&Foo::baz, m)
+```
+
+is a matcher that matches a `Foo` object whose `baz()` method returns
+a value that satisfies matcher `m`.
+
+For example:
+
+| Expression | Description |
+|:-----------------------------|:-----------------------------------|
+| `Field(&Foo::number, Ge(3))` | Matches `x` where `x.number >= 3`. |
+| `Property(&Foo::name, StartsWith("John "))` | Matches `x` where `x.name()` starts with `"John "`. |
+
+Note that in `Property(&Foo::baz, ...)`, method `baz()` must take no
+argument and be declared as `const`.
+
+BTW, `Field()` and `Property()` can also match plain pointers to
+objects. For instance,
+
+```
+Field(&Foo::number, Ge(3))
+```
+
+matches a plain pointer `p` where `p->number >= 3`. If `p` is `NULL`,
+the match will always fail regardless of the inner matcher.
+
+What if you want to validate more than one members at the same time?
+Remember that there is `AllOf()`.
+
+## Validating the Value Pointed to by a Pointer Argument ##
+
+C++ functions often take pointers as arguments. You can use matchers
+like `IsNull()`, `NotNull()`, and other comparison matchers to match a
+pointer, but what if you want to make sure the value _pointed to_ by
+the pointer, instead of the pointer itself, has a certain property?
+Well, you can use the `Pointee(m)` matcher.
+
+`Pointee(m)` matches a pointer iff `m` matches the value the pointer
+points to. For example:
+
+```
+using ::testing::Ge;
+using ::testing::Pointee;
+...
+ EXPECT_CALL(foo, Bar(Pointee(Ge(3))));
+```
+
+expects `foo.Bar()` to be called with a pointer that points to a value
+greater than or equal to 3.
+
+One nice thing about `Pointee()` is that it treats a `NULL` pointer as
+a match failure, so you can write `Pointee(m)` instead of
+
+```
+ AllOf(NotNull(), Pointee(m))
+```
+
+without worrying that a `NULL` pointer will crash your test.
+
+Also, did we tell you that `Pointee()` works with both raw pointers
+**and** smart pointers (`linked_ptr`, `shared_ptr`, `scoped_ptr`, and
+etc)?
+
+What if you have a pointer to pointer? You guessed it - you can use
+nested `Pointee()` to probe deeper inside the value. For example,
+`Pointee(Pointee(Lt(3)))` matches a pointer that points to a pointer
+that points to a number less than 3 (what a mouthful...).
+
+## Testing a Certain Property of an Object ##
+
+Sometimes you want to specify that an object argument has a certain
+property, but there is no existing matcher that does this. If you want
+good error messages, you should define a matcher. If you want to do it
+quick and dirty, you could get away with writing an ordinary function.
+
+Let's say you have a mock function that takes an object of type `Foo`,
+which has an `int bar()` method and an `int baz()` method, and you
+want to constrain that the argument's `bar()` value plus its `baz()`
+value is a given number. Here's how you can define a matcher to do it:
+
+```
+using ::testing::MatcherInterface;
+using ::testing::MatchResultListener;
+
+class BarPlusBazEqMatcher : public MatcherInterface<const Foo&> {
+ public:
+ explicit BarPlusBazEqMatcher(int expected_sum)
+ : expected_sum_(expected_sum) {}
+
+ virtual bool MatchAndExplain(const Foo& foo,
+ MatchResultListener* listener) const {
+ return (foo.bar() + foo.baz()) == expected_sum_;
+ }
+
+ virtual void DescribeTo(::std::ostream* os) const {
+ *os << "bar() + baz() equals " << expected_sum_;
+ }
+
+ virtual void DescribeNegationTo(::std::ostream* os) const {
+ *os << "bar() + baz() does not equal " << expected_sum_;
+ }
+ private:
+ const int expected_sum_;
+};
+
+inline Matcher<const Foo&> BarPlusBazEq(int expected_sum) {
+ return MakeMatcher(new BarPlusBazEqMatcher(expected_sum));
+}
+
+...
+
+ EXPECT_CALL(..., DoThis(BarPlusBazEq(5)))...;
+```
+
+## Matching Containers ##
+
+Sometimes an STL container (e.g. list, vector, map, ...) is passed to
+a mock function and you may want to validate it. Since most STL
+containers support the `==` operator, you can write
+`Eq(expected_container)` or simply `expected_container` to match a
+container exactly.
+
+Sometimes, though, you may want to be more flexible (for example, the
+first element must be an exact match, but the second element can be
+any positive number, and so on). Also, containers used in tests often
+have a small number of elements, and having to define the expected
+container out-of-line is a bit of a hassle.
+
+You can use the `ElementsAre()` or `UnorderedElementsAre()` matcher in
+such cases:
+
+```
+using ::testing::_;
+using ::testing::ElementsAre;
+using ::testing::Gt;
+...
+
+ MOCK_METHOD1(Foo, void(const vector<int>& numbers));
+...
+
+ EXPECT_CALL(mock, Foo(ElementsAre(1, Gt(0), _, 5)));
+```
+
+The above matcher says that the container must have 4 elements, which
+must be 1, greater than 0, anything, and 5 respectively.
+
+If you instead write:
+
+```
+using ::testing::_;
+using ::testing::Gt;
+using ::testing::UnorderedElementsAre;
+...
+
+ MOCK_METHOD1(Foo, void(const vector<int>& numbers));
+...
+
+ EXPECT_CALL(mock, Foo(UnorderedElementsAre(1, Gt(0), _, 5)));
+```
+
+It means that the container must have 4 elements, which under some
+permutation must be 1, greater than 0, anything, and 5 respectively.
+
+`ElementsAre()` and `UnorderedElementsAre()` are overloaded to take 0
+to 10 arguments. If more are needed, you can place them in a C-style
+array and use `ElementsAreArray()` or `UnorderedElementsAreArray()`
+instead:
+
+```
+using ::testing::ElementsAreArray;
+...
+
+ // ElementsAreArray accepts an array of element values.
+ const int expected_vector1[] = { 1, 5, 2, 4, ... };
+ EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector1)));
+
+ // Or, an array of element matchers.
+ Matcher<int> expected_vector2 = { 1, Gt(2), _, 3, ... };
+ EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector2)));
+```
+
+In case the array needs to be dynamically created (and therefore the
+array size cannot be inferred by the compiler), you can give
+`ElementsAreArray()` an additional argument to specify the array size:
+
+```
+using ::testing::ElementsAreArray;
+...
+ int* const expected_vector3 = new int[count];
+ ... fill expected_vector3 with values ...
+ EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector3, count)));
+```
+
+**Tips:**
+
+ * `ElementsAre*()` can be used to match _any_ container that implements the STL iterator pattern (i.e. it has a `const_iterator` type and supports `begin()/end()`), not just the ones defined in STL. It will even work with container types yet to be written - as long as they follows the above pattern.
+ * You can use nested `ElementsAre*()` to match nested (multi-dimensional) containers.
+ * If the container is passed by pointer instead of by reference, just write `Pointee(ElementsAre*(...))`.
+ * The order of elements _matters_ for `ElementsAre*()`. Therefore don't use it with containers whose element order is undefined (e.g. `hash_map`).
+
+## Sharing Matchers ##
+
+Under the hood, a Google Mock matcher object consists of a pointer to
+a ref-counted implementation object. Copying matchers is allowed and
+very efficient, as only the pointer is copied. When the last matcher
+that references the implementation object dies, the implementation
+object will be deleted.
+
+Therefore, if you have some complex matcher that you want to use again
+and again, there is no need to build it every time. Just assign it to a
+matcher variable and use that variable repeatedly! For example,
+
+```
+ Matcher<int> in_range = AllOf(Gt(5), Le(10));
+ ... use in_range as a matcher in multiple EXPECT_CALLs ...
+```
+
+# Setting Expectations #
+
+## Knowing When to Expect ##
+
+`ON_CALL` is likely the single most under-utilized construct in Google Mock.
+
+There are basically two constructs for defining the behavior of a mock object: `ON_CALL` and `EXPECT_CALL`. The difference? `ON_CALL` defines what happens when a mock method is called, but _doesn't imply any expectation on the method being called._ `EXPECT_CALL` not only defines the behavior, but also sets an expectation that _the method will be called with the given arguments, for the given number of times_ (and _in the given order_ when you specify the order too).
+
+Since `EXPECT_CALL` does more, isn't it better than `ON_CALL`? Not really. Every `EXPECT_CALL` adds a constraint on the behavior of the code under test. Having more constraints than necessary is _baaad_ - even worse than not having enough constraints.
+
+This may be counter-intuitive. How could tests that verify more be worse than tests that verify less? Isn't verification the whole point of tests?
+
+The answer, lies in _what_ a test should verify. **A good test verifies the contract of the code.** If a test over-specifies, it doesn't leave enough freedom to the implementation. As a result, changing the implementation without breaking the contract (e.g. refactoring and optimization), which should be perfectly fine to do, can break such tests. Then you have to spend time fixing them, only to see them broken again the next time the implementation is changed.
+
+Keep in mind that one doesn't have to verify more than one property in one test. In fact, **it's a good style to verify only one thing in one test.** If you do that, a bug will likely break only one or two tests instead of dozens (which case would you rather debug?). If you are also in the habit of giving tests descriptive names that tell what they verify, you can often easily guess what's wrong just from the test log itself.
+
+So use `ON_CALL` by default, and only use `EXPECT_CALL` when you actually intend to verify that the call is made. For example, you may have a bunch of `ON_CALL`s in your test fixture to set the common mock behavior shared by all tests in the same group, and write (scarcely) different `EXPECT_CALL`s in different `TEST_F`s to verify different aspects of the code's behavior. Compared with the style where each `TEST` has many `EXPECT_CALL`s, this leads to tests that are more resilient to implementational changes (and thus less likely to require maintenance) and makes the intent of the tests more obvious (so they are easier to maintain when you do need to maintain them).
+
+If you are bothered by the "Uninteresting mock function call" message printed when a mock method without an `EXPECT_CALL` is called, you may use a `NiceMock` instead to suppress all such messages for the mock object, or suppress the message for specific methods by adding `EXPECT_CALL(...).Times(AnyNumber())`. DO NOT suppress it by blindly adding an `EXPECT_CALL(...)`, or you'll have a test that's a pain to maintain.
+
+## Ignoring Uninteresting Calls ##
+
+If you are not interested in how a mock method is called, just don't
+say anything about it. In this case, if the method is ever called,
+Google Mock will perform its default action to allow the test program
+to continue. If you are not happy with the default action taken by
+Google Mock, you can override it using `DefaultValue<T>::Set()`
+(described later in this document) or `ON_CALL()`.
+
+Please note that once you expressed interest in a particular mock
+method (via `EXPECT_CALL()`), all invocations to it must match some
+expectation. If this function is called but the arguments don't match
+any `EXPECT_CALL()` statement, it will be an error.
+
+## Disallowing Unexpected Calls ##
+
+If a mock method shouldn't be called at all, explicitly say so:
+
+```
+using ::testing::_;
+...
+ EXPECT_CALL(foo, Bar(_))
+ .Times(0);
+```
+
+If some calls to the method are allowed, but the rest are not, just
+list all the expected calls:
+
+```
+using ::testing::AnyNumber;
+using ::testing::Gt;
+...
+ EXPECT_CALL(foo, Bar(5));
+ EXPECT_CALL(foo, Bar(Gt(10)))
+ .Times(AnyNumber());
+```
+
+A call to `foo.Bar()` that doesn't match any of the `EXPECT_CALL()`
+statements will be an error.
+
+## Understanding Uninteresting vs Unexpected Calls ##
+
+_Uninteresting_ calls and _unexpected_ calls are different concepts in Google Mock. _Very_ different.
+
+A call `x.Y(...)` is **uninteresting** if there's _not even a single_ `EXPECT_CALL(x, Y(...))` set. In other words, the test isn't interested in the `x.Y()` method at all, as evident in that the test doesn't care to say anything about it.
+
+A call `x.Y(...)` is **unexpected** if there are some `EXPECT_CALL(x, Y(...))s` set, but none of them matches the call. Put another way, the test is interested in the `x.Y()` method (therefore it _explicitly_ sets some `EXPECT_CALL` to verify how it's called); however, the verification fails as the test doesn't expect this particular call to happen.
+
+**An unexpected call is always an error,** as the code under test doesn't behave the way the test expects it to behave.
+
+**By default, an uninteresting call is not an error,** as it violates no constraint specified by the test. (Google Mock's philosophy is that saying nothing means there is no constraint.) However, it leads to a warning, as it _might_ indicate a problem (e.g. the test author might have forgotten to specify a constraint).
+
+In Google Mock, `NiceMock` and `StrictMock` can be used to make a mock class "nice" or "strict". How does this affect uninteresting calls and unexpected calls?
+
+A **nice mock** suppresses uninteresting call warnings. It is less chatty than the default mock, but otherwise is the same. If a test fails with a default mock, it will also fail using a nice mock instead. And vice versa. Don't expect making a mock nice to change the test's result.
+
+A **strict mock** turns uninteresting call warnings into errors. So making a mock strict may change the test's result.
+
+Let's look at an example:
+
+```
+TEST(...) {
+ NiceMock<MockDomainRegistry> mock_registry;
+ EXPECT_CALL(mock_registry, GetDomainOwner("google.com"))
+ .WillRepeatedly(Return("Larry Page"));
+
+ // Use mock_registry in code under test.
+ ... &mock_registry ...
+}
+```
+
+The sole `EXPECT_CALL` here says that all calls to `GetDomainOwner()` must have `"google.com"` as the argument. If `GetDomainOwner("yahoo.com")` is called, it will be an unexpected call, and thus an error. Having a nice mock doesn't change the severity of an unexpected call.
+
+So how do we tell Google Mock that `GetDomainOwner()` can be called with some other arguments as well? The standard technique is to add a "catch all" `EXPECT_CALL`:
+
+```
+ EXPECT_CALL(mock_registry, GetDomainOwner(_))
+ .Times(AnyNumber()); // catches all other calls to this method.
+ EXPECT_CALL(mock_registry, GetDomainOwner("google.com"))
+ .WillRepeatedly(Return("Larry Page"));
+```
+
+Remember that `_` is the wildcard matcher that matches anything. With this, if `GetDomainOwner("google.com")` is called, it will do what the second `EXPECT_CALL` says; if it is called with a different argument, it will do what the first `EXPECT_CALL` says.
+
+Note that the order of the two `EXPECT_CALLs` is important, as a newer `EXPECT_CALL` takes precedence over an older one.
+
+For more on uninteresting calls, nice mocks, and strict mocks, read ["The Nice, the Strict, and the Naggy"](#the-nice-the-strict-and-the-naggy).
+
+## Expecting Ordered Calls ##
+
+Although an `EXPECT_CALL()` statement defined earlier takes precedence
+when Google Mock tries to match a function call with an expectation,
+by default calls don't have to happen in the order `EXPECT_CALL()`
+statements are written. For example, if the arguments match the
+matchers in the third `EXPECT_CALL()`, but not those in the first two,
+then the third expectation will be used.
+
+If you would rather have all calls occur in the order of the
+expectations, put the `EXPECT_CALL()` statements in a block where you
+define a variable of type `InSequence`:
+
+```
+ using ::testing::_;
+ using ::testing::InSequence;
+
+ {
+ InSequence s;
+
+ EXPECT_CALL(foo, DoThis(5));
+ EXPECT_CALL(bar, DoThat(_))
+ .Times(2);
+ EXPECT_CALL(foo, DoThis(6));
+ }
+```
+
+In this example, we expect a call to `foo.DoThis(5)`, followed by two
+calls to `bar.DoThat()` where the argument can be anything, which are
+in turn followed by a call to `foo.DoThis(6)`. If a call occurred
+out-of-order, Google Mock will report an error.
+
+## Expecting Partially Ordered Calls ##
+
+Sometimes requiring everything to occur in a predetermined order can
+lead to brittle tests. For example, we may care about `A` occurring
+before both `B` and `C`, but aren't interested in the relative order
+of `B` and `C`. In this case, the test should reflect our real intent,
+instead of being overly constraining.
+
+Google Mock allows you to impose an arbitrary DAG (directed acyclic
+graph) on the calls. One way to express the DAG is to use the
+[After](CheatSheet.md#the-after-clause) clause of `EXPECT_CALL`.
+
+Another way is via the `InSequence()` clause (not the same as the
+`InSequence` class), which we borrowed from jMock 2. It's less
+flexible than `After()`, but more convenient when you have long chains
+of sequential calls, as it doesn't require you to come up with
+different names for the expectations in the chains. Here's how it
+works:
+
+If we view `EXPECT_CALL()` statements as nodes in a graph, and add an
+edge from node A to node B wherever A must occur before B, we can get
+a DAG. We use the term "sequence" to mean a directed path in this
+DAG. Now, if we decompose the DAG into sequences, we just need to know
+which sequences each `EXPECT_CALL()` belongs to in order to be able to
+reconstruct the original DAG.
+
+So, to specify the partial order on the expectations we need to do two
+things: first to define some `Sequence` objects, and then for each
+`EXPECT_CALL()` say which `Sequence` objects it is part
+of. Expectations in the same sequence must occur in the order they are
+written. For example,
+
+```
+ using ::testing::Sequence;
+
+ Sequence s1, s2;
+
+ EXPECT_CALL(foo, A())
+ .InSequence(s1, s2);
+ EXPECT_CALL(bar, B())
+ .InSequence(s1);
+ EXPECT_CALL(bar, C())
+ .InSequence(s2);
+ EXPECT_CALL(foo, D())
+ .InSequence(s2);
+```
+
+specifies the following DAG (where `s1` is `A -> B`, and `s2` is `A ->
+C -> D`):
+
+```
+ +---> B
+ |
+ A ---|
+ |
+ +---> C ---> D
+```
+
+This means that A must occur before B and C, and C must occur before
+D. There's no restriction about the order other than these.
+
+## Controlling When an Expectation Retires ##
+
+When a mock method is called, Google Mock only consider expectations
+that are still active. An expectation is active when created, and
+becomes inactive (aka _retires_) when a call that has to occur later
+has occurred. For example, in
+
+```
+ using ::testing::_;
+ using ::testing::Sequence;
+
+ Sequence s1, s2;
+
+ EXPECT_CALL(log, Log(WARNING, _, "File too large.")) // #1
+ .Times(AnyNumber())
+ .InSequence(s1, s2);
+ EXPECT_CALL(log, Log(WARNING, _, "Data set is empty.")) // #2
+ .InSequence(s1);
+ EXPECT_CALL(log, Log(WARNING, _, "User not found.")) // #3
+ .InSequence(s2);
+```
+
+as soon as either #2 or #3 is matched, #1 will retire. If a warning
+`"File too large."` is logged after this, it will be an error.
+
+Note that an expectation doesn't retire automatically when it's
+saturated. For example,
+
+```
+using ::testing::_;
+...
+ EXPECT_CALL(log, Log(WARNING, _, _)); // #1
+ EXPECT_CALL(log, Log(WARNING, _, "File too large.")); // #2
+```
+
+says that there will be exactly one warning with the message `"File
+too large."`. If the second warning contains this message too, #2 will
+match again and result in an upper-bound-violated error.
+
+If this is not what you want, you can ask an expectation to retire as
+soon as it becomes saturated:
+
+```
+using ::testing::_;
+...
+ EXPECT_CALL(log, Log(WARNING, _, _)); // #1
+ EXPECT_CALL(log, Log(WARNING, _, "File too large.")) // #2
+ .RetiresOnSaturation();
+```
+
+Here #2 can be used only once, so if you have two warnings with the
+message `"File too large."`, the first will match #2 and the second
+will match #1 - there will be no error.
+
+# Using Actions #
+
+## Returning References from Mock Methods ##
+
+If a mock function's return type is a reference, you need to use
+`ReturnRef()` instead of `Return()` to return a result:
+
+```
+using ::testing::ReturnRef;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD0(GetBar, Bar&());
+};
+...
+
+ MockFoo foo;
+ Bar bar;
+ EXPECT_CALL(foo, GetBar())
+ .WillOnce(ReturnRef(bar));
+```
+
+## Returning Live Values from Mock Methods ##
+
+The `Return(x)` action saves a copy of `x` when the action is
+_created_, and always returns the same value whenever it's
+executed. Sometimes you may want to instead return the _live_ value of
+`x` (i.e. its value at the time when the action is _executed_.).
+
+If the mock function's return type is a reference, you can do it using
+`ReturnRef(x)`, as shown in the previous recipe ("Returning References
+from Mock Methods"). However, Google Mock doesn't let you use
+`ReturnRef()` in a mock function whose return type is not a reference,
+as doing that usually indicates a user error. So, what shall you do?
+
+You may be tempted to try `ByRef()`:
+
+```
+using testing::ByRef;
+using testing::Return;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD0(GetValue, int());
+};
+...
+ int x = 0;
+ MockFoo foo;
+ EXPECT_CALL(foo, GetValue())
+ .WillRepeatedly(Return(ByRef(x)));
+ x = 42;
+ EXPECT_EQ(42, foo.GetValue());
+```
+
+Unfortunately, it doesn't work here. The above code will fail with error:
+
+```
+Value of: foo.GetValue()
+ Actual: 0
+Expected: 42
+```
+
+The reason is that `Return(value)` converts `value` to the actual
+return type of the mock function at the time when the action is
+_created_, not when it is _executed_. (This behavior was chosen for
+the action to be safe when `value` is a proxy object that references
+some temporary objects.) As a result, `ByRef(x)` is converted to an
+`int` value (instead of a `const int&`) when the expectation is set,
+and `Return(ByRef(x))` will always return 0.
+
+`ReturnPointee(pointer)` was provided to solve this problem
+specifically. It returns the value pointed to by `pointer` at the time
+the action is _executed_:
+
+```
+using testing::ReturnPointee;
+...
+ int x = 0;
+ MockFoo foo;
+ EXPECT_CALL(foo, GetValue())
+ .WillRepeatedly(ReturnPointee(&x)); // Note the & here.
+ x = 42;
+ EXPECT_EQ(42, foo.GetValue()); // This will succeed now.
+```
+
+## Combining Actions ##
+
+Want to do more than one thing when a function is called? That's
+fine. `DoAll()` allow you to do sequence of actions every time. Only
+the return value of the last action in the sequence will be used.
+
+```
+using ::testing::DoAll;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD1(Bar, bool(int n));
+};
+...
+
+ EXPECT_CALL(foo, Bar(_))
+ .WillOnce(DoAll(action_1,
+ action_2,
+ ...
+ action_n));
+```
+
+## Mocking Side Effects ##
+
+Sometimes a method exhibits its effect not via returning a value but
+via side effects. For example, it may change some global state or
+modify an output argument. To mock side effects, in general you can
+define your own action by implementing `::testing::ActionInterface`.
+
+If all you need to do is to change an output argument, the built-in
+`SetArgPointee()` action is convenient:
+
+```
+using ::testing::SetArgPointee;
+
+class MockMutator : public Mutator {
+ public:
+ MOCK_METHOD2(Mutate, void(bool mutate, int* value));
+ ...
+};
+...
+
+ MockMutator mutator;
+ EXPECT_CALL(mutator, Mutate(true, _))
+ .WillOnce(SetArgPointee<1>(5));
+```
+
+In this example, when `mutator.Mutate()` is called, we will assign 5
+to the `int` variable pointed to by argument #1
+(0-based).
+
+`SetArgPointee()` conveniently makes an internal copy of the
+value you pass to it, removing the need to keep the value in scope and
+alive. The implication however is that the value must have a copy
+constructor and assignment operator.
+
+If the mock method also needs to return a value as well, you can chain
+`SetArgPointee()` with `Return()` using `DoAll()`:
+
+```
+using ::testing::_;
+using ::testing::Return;
+using ::testing::SetArgPointee;
+
+class MockMutator : public Mutator {
+ public:
+ ...
+ MOCK_METHOD1(MutateInt, bool(int* value));
+};
+...
+
+ MockMutator mutator;
+ EXPECT_CALL(mutator, MutateInt(_))
+ .WillOnce(DoAll(SetArgPointee<0>(5),
+ Return(true)));
+```
+
+If the output argument is an array, use the
+`SetArrayArgument<N>(first, last)` action instead. It copies the
+elements in source range `[first, last)` to the array pointed to by
+the `N`-th (0-based) argument:
+
+```
+using ::testing::NotNull;
+using ::testing::SetArrayArgument;
+
+class MockArrayMutator : public ArrayMutator {
+ public:
+ MOCK_METHOD2(Mutate, void(int* values, int num_values));
+ ...
+};
+...
+
+ MockArrayMutator mutator;
+ int values[5] = { 1, 2, 3, 4, 5 };
+ EXPECT_CALL(mutator, Mutate(NotNull(), 5))
+ .WillOnce(SetArrayArgument<0>(values, values + 5));
+```
+
+This also works when the argument is an output iterator:
+
+```
+using ::testing::_;
+using ::testing::SetArrayArgument;
+
+class MockRolodex : public Rolodex {
+ public:
+ MOCK_METHOD1(GetNames, void(std::back_insert_iterator<vector<string> >));
+ ...
+};
+...
+
+ MockRolodex rolodex;
+ vector<string> names;
+ names.push_back("George");
+ names.push_back("John");
+ names.push_back("Thomas");
+ EXPECT_CALL(rolodex, GetNames(_))
+ .WillOnce(SetArrayArgument<0>(names.begin(), names.end()));
+```
+
+## Changing a Mock Object's Behavior Based on the State ##
+
+If you expect a call to change the behavior of a mock object, you can use `::testing::InSequence` to specify different behaviors before and after the call:
+
+```
+using ::testing::InSequence;
+using ::testing::Return;
+
+...
+ {
+ InSequence seq;
+ EXPECT_CALL(my_mock, IsDirty())
+ .WillRepeatedly(Return(true));
+ EXPECT_CALL(my_mock, Flush());
+ EXPECT_CALL(my_mock, IsDirty())
+ .WillRepeatedly(Return(false));
+ }
+ my_mock.FlushIfDirty();
+```
+
+This makes `my_mock.IsDirty()` return `true` before `my_mock.Flush()` is called and return `false` afterwards.
+
+If the behavior change is more complex, you can store the effects in a variable and make a mock method get its return value from that variable:
+
+```
+using ::testing::_;
+using ::testing::SaveArg;
+using ::testing::Return;
+
+ACTION_P(ReturnPointee, p) { return *p; }
+...
+ int previous_value = 0;
+ EXPECT_CALL(my_mock, GetPrevValue())
+ .WillRepeatedly(ReturnPointee(&previous_value));
+ EXPECT_CALL(my_mock, UpdateValue(_))
+ .WillRepeatedly(SaveArg<0>(&previous_value));
+ my_mock.DoSomethingToUpdateValue();
+```
+
+Here `my_mock.GetPrevValue()` will always return the argument of the last `UpdateValue()` call.
+
+## Setting the Default Value for a Return Type ##
+
+If a mock method's return type is a built-in C++ type or pointer, by
+default it will return 0 when invoked. Also, in C++ 11 and above, a mock
+method whose return type has a default constructor will return a default-constructed
+value by default. You only need to specify an
+action if this default value doesn't work for you.
+
+Sometimes, you may want to change this default value, or you may want
+to specify a default value for types Google Mock doesn't know
+about. You can do this using the `::testing::DefaultValue` class
+template:
+
+```
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD0(CalculateBar, Bar());
+};
+...
+
+ Bar default_bar;
+ // Sets the default return value for type Bar.
+ DefaultValue<Bar>::Set(default_bar);
+
+ MockFoo foo;
+
+ // We don't need to specify an action here, as the default
+ // return value works for us.
+ EXPECT_CALL(foo, CalculateBar());
+
+ foo.CalculateBar(); // This should return default_bar.
+
+ // Unsets the default return value.
+ DefaultValue<Bar>::Clear();
+```
+
+Please note that changing the default value for a type can make you
+tests hard to understand. We recommend you to use this feature
+judiciously. For example, you may want to make sure the `Set()` and
+`Clear()` calls are right next to the code that uses your mock.
+
+## Setting the Default Actions for a Mock Method ##
+
+You've learned how to change the default value of a given
+type. However, this may be too coarse for your purpose: perhaps you
+have two mock methods with the same return type and you want them to
+have different behaviors. The `ON_CALL()` macro allows you to
+customize your mock's behavior at the method level:
+
+```
+using ::testing::_;
+using ::testing::AnyNumber;
+using ::testing::Gt;
+using ::testing::Return;
+...
+ ON_CALL(foo, Sign(_))
+ .WillByDefault(Return(-1));
+ ON_CALL(foo, Sign(0))
+ .WillByDefault(Return(0));
+ ON_CALL(foo, Sign(Gt(0)))
+ .WillByDefault(Return(1));
+
+ EXPECT_CALL(foo, Sign(_))
+ .Times(AnyNumber());
+
+ foo.Sign(5); // This should return 1.
+ foo.Sign(-9); // This should return -1.
+ foo.Sign(0); // This should return 0.
+```
+
+As you may have guessed, when there are more than one `ON_CALL()`
+statements, the news order take precedence over the older ones. In
+other words, the **last** one that matches the function arguments will
+be used. This matching order allows you to set up the common behavior
+in a mock object's constructor or the test fixture's set-up phase and
+specialize the mock's behavior later.
+
+## Using Functions/Methods/Functors as Actions ##
+
+If the built-in actions don't suit you, you can easily use an existing
+function, method, or functor as an action:
+
+```
+using ::testing::_;
+using ::testing::Invoke;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD2(Sum, int(int x, int y));
+ MOCK_METHOD1(ComplexJob, bool(int x));
+};
+
+int CalculateSum(int x, int y) { return x + y; }
+
+class Helper {
+ public:
+ bool ComplexJob(int x);
+};
+...
+
+ MockFoo foo;
+ Helper helper;
+ EXPECT_CALL(foo, Sum(_, _))
+ .WillOnce(Invoke(CalculateSum));
+ EXPECT_CALL(foo, ComplexJob(_))
+ .WillOnce(Invoke(&helper, &Helper::ComplexJob));
+
+ foo.Sum(5, 6); // Invokes CalculateSum(5, 6).
+ foo.ComplexJob(10); // Invokes helper.ComplexJob(10);
+```
+
+The only requirement is that the type of the function, etc must be
+_compatible_ with the signature of the mock function, meaning that the
+latter's arguments can be implicitly converted to the corresponding
+arguments of the former, and the former's return type can be
+implicitly converted to that of the latter. So, you can invoke
+something whose type is _not_ exactly the same as the mock function,
+as long as it's safe to do so - nice, huh?
+
+## Invoking a Function/Method/Functor Without Arguments ##
+
+`Invoke()` is very useful for doing actions that are more complex. It
+passes the mock function's arguments to the function or functor being
+invoked such that the callee has the full context of the call to work
+with. If the invoked function is not interested in some or all of the
+arguments, it can simply ignore them.
+
+Yet, a common pattern is that a test author wants to invoke a function
+without the arguments of the mock function. `Invoke()` allows her to
+do that using a wrapper function that throws away the arguments before
+invoking an underlining nullary function. Needless to say, this can be
+tedious and obscures the intent of the test.
+
+`InvokeWithoutArgs()` solves this problem. It's like `Invoke()` except
+that it doesn't pass the mock function's arguments to the
+callee. Here's an example:
+
+```
+using ::testing::_;
+using ::testing::InvokeWithoutArgs;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD1(ComplexJob, bool(int n));
+};
+
+bool Job1() { ... }
+...
+
+ MockFoo foo;
+ EXPECT_CALL(foo, ComplexJob(_))
+ .WillOnce(InvokeWithoutArgs(Job1));
+
+ foo.ComplexJob(10); // Invokes Job1().
+```
+
+## Invoking an Argument of the Mock Function ##
+
+Sometimes a mock function will receive a function pointer or a functor
+(in other words, a "callable") as an argument, e.g.
+
+```
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD2(DoThis, bool(int n, bool (*fp)(int)));
+};
+```
+
+and you may want to invoke this callable argument:
+
+```
+using ::testing::_;
+...
+ MockFoo foo;
+ EXPECT_CALL(foo, DoThis(_, _))
+ .WillOnce(...);
+ // Will execute (*fp)(5), where fp is the
+ // second argument DoThis() receives.
+```
+
+Arghh, you need to refer to a mock function argument but your version
+of C++ has no lambdas, so you have to define your own action. :-(
+Or do you really?
+
+Well, Google Mock has an action to solve _exactly_ this problem:
+
+```
+ InvokeArgument<N>(arg_1, arg_2, ..., arg_m)
+```
+
+will invoke the `N`-th (0-based) argument the mock function receives,
+with `arg_1`, `arg_2`, ..., and `arg_m`. No matter if the argument is
+a function pointer or a functor, Google Mock handles them both.
+
+With that, you could write:
+
+```
+using ::testing::_;
+using ::testing::InvokeArgument;
+...
+ EXPECT_CALL(foo, DoThis(_, _))
+ .WillOnce(InvokeArgument<1>(5));
+ // Will execute (*fp)(5), where fp is the
+ // second argument DoThis() receives.
+```
+
+What if the callable takes an argument by reference? No problem - just
+wrap it inside `ByRef()`:
+
+```
+...
+ MOCK_METHOD1(Bar, bool(bool (*fp)(int, const Helper&)));
+...
+using ::testing::_;
+using ::testing::ByRef;
+using ::testing::InvokeArgument;
+...
+
+ MockFoo foo;
+ Helper helper;
+ ...
+ EXPECT_CALL(foo, Bar(_))
+ .WillOnce(InvokeArgument<0>(5, ByRef(helper)));
+ // ByRef(helper) guarantees that a reference to helper, not a copy of it,
+ // will be passed to the callable.
+```
+
+What if the callable takes an argument by reference and we do **not**
+wrap the argument in `ByRef()`? Then `InvokeArgument()` will _make a
+copy_ of the argument, and pass a _reference to the copy_, instead of
+a reference to the original value, to the callable. This is especially
+handy when the argument is a temporary value:
+
+```
+...
+ MOCK_METHOD1(DoThat, bool(bool (*f)(const double& x, const string& s)));
+...
+using ::testing::_;
+using ::testing::InvokeArgument;
+...
+
+ MockFoo foo;
+ ...
+ EXPECT_CALL(foo, DoThat(_))
+ .WillOnce(InvokeArgument<0>(5.0, string("Hi")));
+ // Will execute (*f)(5.0, string("Hi")), where f is the function pointer
+ // DoThat() receives. Note that the values 5.0 and string("Hi") are
+ // temporary and dead once the EXPECT_CALL() statement finishes. Yet
+ // it's fine to perform this action later, since a copy of the values
+ // are kept inside the InvokeArgument action.
+```
+
+## Ignoring an Action's Result ##
+
+Sometimes you have an action that returns _something_, but you need an
+action that returns `void` (perhaps you want to use it in a mock
+function that returns `void`, or perhaps it needs to be used in
+`DoAll()` and it's not the last in the list). `IgnoreResult()` lets
+you do that. For example:
+
+```
+using ::testing::_;
+using ::testing::Invoke;
+using ::testing::Return;
+
+int Process(const MyData& data);
+string DoSomething();
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD1(Abc, void(const MyData& data));
+ MOCK_METHOD0(Xyz, bool());
+};
+...
+
+ MockFoo foo;
+ EXPECT_CALL(foo, Abc(_))
+ // .WillOnce(Invoke(Process));
+ // The above line won't compile as Process() returns int but Abc() needs
+ // to return void.
+ .WillOnce(IgnoreResult(Invoke(Process)));
+
+ EXPECT_CALL(foo, Xyz())
+ .WillOnce(DoAll(IgnoreResult(Invoke(DoSomething)),
+ // Ignores the string DoSomething() returns.
+ Return(true)));
+```
+
+Note that you **cannot** use `IgnoreResult()` on an action that already
+returns `void`. Doing so will lead to ugly compiler errors.
+
+## Selecting an Action's Arguments ##
+
+Say you have a mock function `Foo()` that takes seven arguments, and
+you have a custom action that you want to invoke when `Foo()` is
+called. Trouble is, the custom action only wants three arguments:
+
+```
+using ::testing::_;
+using ::testing::Invoke;
+...
+ MOCK_METHOD7(Foo, bool(bool visible, const string& name, int x, int y,
+ const map<pair<int, int>, double>& weight,
+ double min_weight, double max_wight));
+...
+
+bool IsVisibleInQuadrant1(bool visible, int x, int y) {
+ return visible && x >= 0 && y >= 0;
+}
+...
+
+ EXPECT_CALL(mock, Foo(_, _, _, _, _, _, _))
+ .WillOnce(Invoke(IsVisibleInQuadrant1)); // Uh, won't compile. :-(
+```
+
+To please the compiler God, you can to define an "adaptor" that has
+the same signature as `Foo()` and calls the custom action with the
+right arguments:
+
+```
+using ::testing::_;
+using ::testing::Invoke;
+
+bool MyIsVisibleInQuadrant1(bool visible, const string& name, int x, int y,
+ const map<pair<int, int>, double>& weight,
+ double min_weight, double max_wight) {
+ return IsVisibleInQuadrant1(visible, x, y);
+}
+...
+
+ EXPECT_CALL(mock, Foo(_, _, _, _, _, _, _))
+ .WillOnce(Invoke(MyIsVisibleInQuadrant1)); // Now it works.
+```
+
+But isn't this awkward?
+
+Google Mock provides a generic _action adaptor_, so you can spend your
+time minding more important business than writing your own
+adaptors. Here's the syntax:
+
+```
+ WithArgs<N1, N2, ..., Nk>(action)
+```
+
+creates an action that passes the arguments of the mock function at
+the given indices (0-based) to the inner `action` and performs
+it. Using `WithArgs`, our original example can be written as:
+
+```
+using ::testing::_;
+using ::testing::Invoke;
+using ::testing::WithArgs;
+...
+ EXPECT_CALL(mock, Foo(_, _, _, _, _, _, _))
+ .WillOnce(WithArgs<0, 2, 3>(Invoke(IsVisibleInQuadrant1)));
+ // No need to define your own adaptor.
+```
+
+For better readability, Google Mock also gives you:
+
+ * `WithoutArgs(action)` when the inner `action` takes _no_ argument, and
+ * `WithArg<N>(action)` (no `s` after `Arg`) when the inner `action` takes _one_ argument.
+
+As you may have realized, `InvokeWithoutArgs(...)` is just syntactic
+sugar for `WithoutArgs(Invoke(...))`.
+
+Here are more tips:
+
+ * The inner action used in `WithArgs` and friends does not have to be `Invoke()` -- it can be anything.
+ * You can repeat an argument in the argument list if necessary, e.g. `WithArgs<2, 3, 3, 5>(...)`.
+ * You can change the order of the arguments, e.g. `WithArgs<3, 2, 1>(...)`.
+ * The types of the selected arguments do _not_ have to match the signature of the inner action exactly. It works as long as they can be implicitly converted to the corresponding arguments of the inner action. For example, if the 4-th argument of the mock function is an `int` and `my_action` takes a `double`, `WithArg<4>(my_action)` will work.
+
+## Ignoring Arguments in Action Functions ##
+
+The selecting-an-action's-arguments recipe showed us one way to make a
+mock function and an action with incompatible argument lists fit
+together. The downside is that wrapping the action in
+`WithArgs<...>()` can get tedious for people writing the tests.
+
+If you are defining a function, method, or functor to be used with
+`Invoke*()`, and you are not interested in some of its arguments, an
+alternative to `WithArgs` is to declare the uninteresting arguments as
+`Unused`. This makes the definition less cluttered and less fragile in
+case the types of the uninteresting arguments change. It could also
+increase the chance the action function can be reused. For example,
+given
+
+```
+ MOCK_METHOD3(Foo, double(const string& label, double x, double y));
+ MOCK_METHOD3(Bar, double(int index, double x, double y));
+```
+
+instead of
+
+```
+using ::testing::_;
+using ::testing::Invoke;
+
+double DistanceToOriginWithLabel(const string& label, double x, double y) {
+ return sqrt(x*x + y*y);
+}
+
+double DistanceToOriginWithIndex(int index, double x, double y) {
+ return sqrt(x*x + y*y);
+}
+...
+
+ EXEPCT_CALL(mock, Foo("abc", _, _))
+ .WillOnce(Invoke(DistanceToOriginWithLabel));
+ EXEPCT_CALL(mock, Bar(5, _, _))
+ .WillOnce(Invoke(DistanceToOriginWithIndex));
+```
+
+you could write
+
+```
+using ::testing::_;
+using ::testing::Invoke;
+using ::testing::Unused;
+
+double DistanceToOrigin(Unused, double x, double y) {
+ return sqrt(x*x + y*y);
+}
+...
+
+ EXEPCT_CALL(mock, Foo("abc", _, _))
+ .WillOnce(Invoke(DistanceToOrigin));
+ EXEPCT_CALL(mock, Bar(5, _, _))
+ .WillOnce(Invoke(DistanceToOrigin));
+```
+
+## Sharing Actions ##
+
+Just like matchers, a Google Mock action object consists of a pointer
+to a ref-counted implementation object. Therefore copying actions is
+also allowed and very efficient. When the last action that references
+the implementation object dies, the implementation object will be
+deleted.
+
+If you have some complex action that you want to use again and again,
+you may not have to build it from scratch every time. If the action
+doesn't have an internal state (i.e. if it always does the same thing
+no matter how many times it has been called), you can assign it to an
+action variable and use that variable repeatedly. For example:
+
+```
+ Action<bool(int*)> set_flag = DoAll(SetArgPointee<0>(5),
+ Return(true));
+ ... use set_flag in .WillOnce() and .WillRepeatedly() ...
+```
+
+However, if the action has its own state, you may be surprised if you
+share the action object. Suppose you have an action factory
+`IncrementCounter(init)` which creates an action that increments and
+returns a counter whose initial value is `init`, using two actions
+created from the same expression and using a shared action will
+exihibit different behaviors. Example:
+
+```
+ EXPECT_CALL(foo, DoThis())
+ .WillRepeatedly(IncrementCounter(0));
+ EXPECT_CALL(foo, DoThat())
+ .WillRepeatedly(IncrementCounter(0));
+ foo.DoThis(); // Returns 1.
+ foo.DoThis(); // Returns 2.
+ foo.DoThat(); // Returns 1 - Blah() uses a different
+ // counter than Bar()'s.
+```
+
+versus
+
+```
+ Action<int()> increment = IncrementCounter(0);
+
+ EXPECT_CALL(foo, DoThis())
+ .WillRepeatedly(increment);
+ EXPECT_CALL(foo, DoThat())
+ .WillRepeatedly(increment);
+ foo.DoThis(); // Returns 1.
+ foo.DoThis(); // Returns 2.
+ foo.DoThat(); // Returns 3 - the counter is shared.
+```

+
+## Mocking Methods That Use Move-Only Types ##
+
+C++11 introduced *move-only types*. A move-only-typed value can be moved from
+one object to another, but cannot be copied. `std::unique_ptr<T>` is
+probably the most commonly used move-only type.
+
+Mocking a method that takes and/or returns move-only types presents some
+challenges, but nothing insurmountable. This recipe shows you how you can do it.
+Note that the support for move-only method arguments was only introduced to
+gMock in April 2017; in older code, you may find more complex
+[workarounds](#LegacyMoveOnly) for lack of this feature.
+
+Let’s say we are working on a fictional project that lets one post and share
+snippets called “buzzes”. Your code uses these types:
+
+```cpp
+enum class AccessLevel { kInternal, kPublic };
+
+class Buzz {
+ public:
+ explicit Buzz(AccessLevel access) { … }
+ ...
+};
+
+class Buzzer {
+ public:
+ virtual ~Buzzer() {}
+ virtual std::unique_ptr<Buzz> MakeBuzz(StringPiece text) = 0;
+ virtual bool ShareBuzz(std::unique_ptr<Buzz> buzz, int64_t timestamp) = 0;
+ ...
+};
+```
+
+A `Buzz` object represents a snippet being posted. A class that implements the
+`Buzzer` interface is capable of creating and sharing `Buzz`es. Methods in
+`Buzzer` may return a `unique_ptr<Buzz>` or take a
+`unique_ptr<Buzz>`. Now we need to mock `Buzzer` in our tests.
+
+To mock a method that accepts or returns move-only types, you just use the
+familiar `MOCK_METHOD` syntax as usual:
+
+```cpp
+class MockBuzzer : public Buzzer {
+ public:
+ MOCK_METHOD1(MakeBuzz, std::unique_ptr<Buzz>(StringPiece text));
+ MOCK_METHOD2(ShareBuzz, bool(std::unique_ptr<Buzz> buzz, int64_t timestamp));
+};
+```
+
+Now that we have the mock class defined, we can use it in tests. In the
+following code examples, we assume that we have defined a `MockBuzzer` object
+named `mock_buzzer_`:
+
+```cpp
+ MockBuzzer mock_buzzer_;
+```
+
+First let’s see how we can set expectations on the `MakeBuzz()` method, which
+returns a `unique_ptr<Buzz>`.
+
+As usual, if you set an expectation without an action (i.e. the `.WillOnce()` or
+`.WillRepeated()` clause), when that expectation fires, the default action for
+that method will be taken. Since `unique_ptr<>` has a default constructor
+that returns a null `unique_ptr`, that’s what you’ll get if you don’t specify an
+action:
+
+```cpp
+ // Use the default action.
+ EXPECT_CALL(mock_buzzer_, MakeBuzz("hello"));
+
+ // Triggers the previous EXPECT_CALL.
+ EXPECT_EQ(nullptr, mock_buzzer_.MakeBuzz("hello"));
+```
+
+If you are not happy with the default action, you can tweak it as usual; see
+[Setting Default Actions](#OnCall).
+
+If you just need to return a pre-defined move-only value, you can use the
+`Return(ByMove(...))` action:
+
+```cpp
+ // When this fires, the unique_ptr<> specified by ByMove(...) will
+ // be returned.
+ EXPECT_CALL(mock_buzzer_, MakeBuzz("world"))
+ .WillOnce(Return(ByMove(MakeUnique<Buzz>(AccessLevel::kInternal))));
+
+ EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("world"));
+```
+
+Note that `ByMove()` is essential here - if you drop it, the code won’t compile.
+
+Quiz time! What do you think will happen if a `Return(ByMove(...))` action is
+performed more than once (e.g. you write
+`….WillRepeatedly(Return(ByMove(...)));`)? Come think of it, after the first
+time the action runs, the source value will be consumed (since it’s a move-only
+value), so the next time around, there’s no value to move from -- you’ll get a
+run-time error that `Return(ByMove(...))` can only be run once.
+
+If you need your mock method to do more than just moving a pre-defined value,
+remember that you can always use a lambda or a callable object, which can do
+pretty much anything you want:
+
+```cpp
+ EXPECT_CALL(mock_buzzer_, MakeBuzz("x"))
+ .WillRepeatedly([](StringPiece text) {
+ return MakeUnique<Buzz>(AccessLevel::kInternal);
+ });
+
+ EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("x"));
+ EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("x"));
+```
+
+Every time this `EXPECT_CALL` fires, a new `unique_ptr<Buzz>` will be
+created and returned. You cannot do this with `Return(ByMove(...))`.
+
+That covers returning move-only values; but how do we work with methods
+accepting move-only arguments? The answer is that they work normally, although
+some actions will not compile when any of method's arguments are move-only. You
+can always use `Return`, or a [lambda or functor](#FunctionsAsActions):
+
+```cpp
+ using ::testing::Unused;
+
+ EXPECT_CALL(mock_buzzer_, ShareBuzz(NotNull(), _)) .WillOnce(Return(true));
+ EXPECT_TRUE(mock_buzzer_.ShareBuzz(MakeUnique<Buzz>(AccessLevel::kInternal)),
+ 0);
+
+ EXPECT_CALL(mock_buzzer_, ShareBuzz(_, _)) .WillOnce(
+ [](std::unique_ptr<Buzz> buzz, Unused) { return buzz != nullptr; });
+ EXPECT_FALSE(mock_buzzer_.ShareBuzz(nullptr, 0));
+```
+
+Many built-in actions (`WithArgs`, `WithoutArgs`,`DeleteArg`, `SaveArg`, ...)
+could in principle support move-only arguments, but the support for this is not
+implemented yet. If this is blocking you, please file a bug.
+
+A few actions (e.g. `DoAll`) copy their arguments internally, so they can never
+work with non-copyable objects; you'll have to use functors instead.
+
+##### Legacy workarounds for move-only types {#LegacyMoveOnly}
+
+Support for move-only function arguments was only introduced to gMock in April
+2017. In older code, you may encounter the following workaround for the lack of
+this feature (it is no longer necessary - we're including it just for
+reference):
+
+```cpp
+class MockBuzzer : public Buzzer {
+ public:
+ MOCK_METHOD2(DoShareBuzz, bool(Buzz* buzz, Time timestamp));
+ bool ShareBuzz(std::unique_ptr<Buzz> buzz, Time timestamp) override {
+ return DoShareBuzz(buzz.get(), timestamp);
+ }
+};
+```
+
+The trick is to delegate the `ShareBuzz()` method to a mock method (let’s call
+it `DoShareBuzz()`) that does not take move-only parameters. Then, instead of
+setting expectations on `ShareBuzz()`, you set them on the `DoShareBuzz()` mock
+method:
+
+```cpp
+ MockBuzzer mock_buzzer_;
+ EXPECT_CALL(mock_buzzer_, DoShareBuzz(NotNull(), _));
+
+ // When one calls ShareBuzz() on the MockBuzzer like this, the call is
+ // forwarded to DoShareBuzz(), which is mocked. Therefore this statement
+ // will trigger the above EXPECT_CALL.
+ mock_buzzer_.ShareBuzz(MakeUnique<Buzz>(AccessLevel::kInternal), 0);
+```
+
+
+
+## Making the Compilation Faster ##
+
+Believe it or not, the _vast majority_ of the time spent on compiling
+a mock class is in generating its constructor and destructor, as they
+perform non-trivial tasks (e.g. verification of the
+expectations). What's more, mock methods with different signatures
+have different types and thus their constructors/destructors need to
+be generated by the compiler separately. As a result, if you mock many
+different types of methods, compiling your mock class can get really
+slow.
+
+If you are experiencing slow compilation, you can move the definition
+of your mock class' constructor and destructor out of the class body
+and into a `.cpp` file. This way, even if you `#include` your mock
+class in N files, the compiler only needs to generate its constructor
+and destructor once, resulting in a much faster compilation.
+
+Let's illustrate the idea using an example. Here's the definition of a
+mock class before applying this recipe:
+
+```
+// File mock_foo.h.
+...
+class MockFoo : public Foo {
+ public:
+ // Since we don't declare the constructor or the destructor,
+ // the compiler will generate them in every translation unit
+ // where this mock class is used.
+
+ MOCK_METHOD0(DoThis, int());
+ MOCK_METHOD1(DoThat, bool(const char* str));
+ ... more mock methods ...
+};
+```
+
+After the change, it would look like:
+
+```
+// File mock_foo.h.
+...
+class MockFoo : public Foo {
+ public:
+ // The constructor and destructor are declared, but not defined, here.
+ MockFoo();
+ virtual ~MockFoo();
+
+ MOCK_METHOD0(DoThis, int());
+ MOCK_METHOD1(DoThat, bool(const char* str));
+ ... more mock methods ...
+};
+```
+and
+```
+// File mock_foo.cpp.
+#include "path/to/mock_foo.h"
+
+// The definitions may appear trivial, but the functions actually do a
+// lot of things through the constructors/destructors of the member
+// variables used to implement the mock methods.
+MockFoo::MockFoo() {}
+MockFoo::~MockFoo() {}
+```
+
+## Forcing a Verification ##
+
+When it's being destroyed, your friendly mock object will automatically
+verify that all expectations on it have been satisfied, and will
+generate [Google Test](../../googletest/) failures
+if not. This is convenient as it leaves you with one less thing to
+worry about. That is, unless you are not sure if your mock object will
+be destroyed.
+
+How could it be that your mock object won't eventually be destroyed?
+Well, it might be created on the heap and owned by the code you are
+testing. Suppose there's a bug in that code and it doesn't delete the
+mock object properly - you could end up with a passing test when
+there's actually a bug.
+
+Using a heap checker is a good idea and can alleviate the concern, but
+its implementation may not be 100% reliable. So, sometimes you do want
+to _force_ Google Mock to verify a mock object before it is
+(hopefully) destructed. You can do this with
+`Mock::VerifyAndClearExpectations(&mock_object)`:
+
+```
+TEST(MyServerTest, ProcessesRequest) {
+ using ::testing::Mock;
+
+ MockFoo* const foo = new MockFoo;
+ EXPECT_CALL(*foo, ...)...;
+ // ... other expectations ...
+
+ // server now owns foo.
+ MyServer server(foo);
+ server.ProcessRequest(...);
+
+ // In case that server's destructor will forget to delete foo,
+ // this will verify the expectations anyway.
+ Mock::VerifyAndClearExpectations(foo);
+} // server is destroyed when it goes out of scope here.
+```
+
+**Tip:** The `Mock::VerifyAndClearExpectations()` function returns a
+`bool` to indicate whether the verification was successful (`true` for
+yes), so you can wrap that function call inside a `ASSERT_TRUE()` if
+there is no point going further when the verification has failed.
+
+## Using Check Points ##
+
+Sometimes you may want to "reset" a mock object at various check
+points in your test: at each check point, you verify that all existing
+expectations on the mock object have been satisfied, and then you set
+some new expectations on it as if it's newly created. This allows you
+to work with a mock object in "phases" whose sizes are each
+manageable.
+
+One such scenario is that in your test's `SetUp()` function, you may
+want to put the object you are testing into a certain state, with the
+help from a mock object. Once in the desired state, you want to clear
+all expectations on the mock, such that in the `TEST_F` body you can
+set fresh expectations on it.
+
+As you may have figured out, the `Mock::VerifyAndClearExpectations()`
+function we saw in the previous recipe can help you here. Or, if you
+are using `ON_CALL()` to set default actions on the mock object and
+want to clear the default actions as well, use
+`Mock::VerifyAndClear(&mock_object)` instead. This function does what
+`Mock::VerifyAndClearExpectations(&mock_object)` does and returns the
+same `bool`, **plus** it clears the `ON_CALL()` statements on
+`mock_object` too.
+
+Another trick you can use to achieve the same effect is to put the
+expectations in sequences and insert calls to a dummy "check-point"
+function at specific places. Then you can verify that the mock
+function calls do happen at the right time. For example, if you are
+exercising code:
+
+```
+Foo(1);
+Foo(2);
+Foo(3);
+```
+
+and want to verify that `Foo(1)` and `Foo(3)` both invoke
+`mock.Bar("a")`, but `Foo(2)` doesn't invoke anything. You can write:
+
+```
+using ::testing::MockFunction;
+
+TEST(FooTest, InvokesBarCorrectly) {
+ MyMock mock;
+ // Class MockFunction<F> has exactly one mock method. It is named
+ // Call() and has type F.
+ MockFunction<void(string check_point_name)> check;
+ {
+ InSequence s;
+
+ EXPECT_CALL(mock, Bar("a"));
+ EXPECT_CALL(check, Call("1"));
+ EXPECT_CALL(check, Call("2"));
+ EXPECT_CALL(mock, Bar("a"));
+ }
+ Foo(1);
+ check.Call("1");
+ Foo(2);
+ check.Call("2");
+ Foo(3);
+}
+```
+
+The expectation spec says that the first `Bar("a")` must happen before
+check point "1", the second `Bar("a")` must happen after check point "2",
+and nothing should happen between the two check points. The explicit
+check points make it easy to tell which `Bar("a")` is called by which
+call to `Foo()`.
+
+## Mocking Destructors ##
+
+Sometimes you want to make sure a mock object is destructed at the
+right time, e.g. after `bar->A()` is called but before `bar->B()` is
+called. We already know that you can specify constraints on the order
+of mock function calls, so all we need to do is to mock the destructor
+of the mock function.
+
+This sounds simple, except for one problem: a destructor is a special
+function with special syntax and special semantics, and the
+`MOCK_METHOD0` macro doesn't work for it:
+
+```
+ MOCK_METHOD0(~MockFoo, void()); // Won't compile!
+```
+
+The good news is that you can use a simple pattern to achieve the same
+effect. First, add a mock function `Die()` to your mock class and call
+it in the destructor, like this:
+
+```
+class MockFoo : public Foo {
+ ...
+ // Add the following two lines to the mock class.
+ MOCK_METHOD0(Die, void());
+ virtual ~MockFoo() { Die(); }
+};
+```
+
+(If the name `Die()` clashes with an existing symbol, choose another
+name.) Now, we have translated the problem of testing when a `MockFoo`
+object dies to testing when its `Die()` method is called:
+
+```
+ MockFoo* foo = new MockFoo;
+ MockBar* bar = new MockBar;
+ ...
+ {
+ InSequence s;
+
+ // Expects *foo to die after bar->A() and before bar->B().
+ EXPECT_CALL(*bar, A());
+ EXPECT_CALL(*foo, Die());
+ EXPECT_CALL(*bar, B());
+ }
+```
+
+And that's that.
+
+## Using Google Mock and Threads ##
+
+**IMPORTANT NOTE:** What we describe in this recipe is **ONLY** true on
+platforms where Google Mock is thread-safe. Currently these are only
+platforms that support the pthreads library (this includes Linux and Mac).
+To make it thread-safe on other platforms we only need to implement
+some synchronization operations in `"gtest/internal/gtest-port.h"`.
+
+In a **unit** test, it's best if you could isolate and test a piece of
+code in a single-threaded context. That avoids race conditions and
+dead locks, and makes debugging your test much easier.
+
+Yet many programs are multi-threaded, and sometimes to test something
+we need to pound on it from more than one thread. Google Mock works
+for this purpose too.
+
+Remember the steps for using a mock:
+
+ 1. Create a mock object `foo`.
+ 1. Set its default actions and expectations using `ON_CALL()` and `EXPECT_CALL()`.
+ 1. The code under test calls methods of `foo`.
+ 1. Optionally, verify and reset the mock.
+ 1. Destroy the mock yourself, or let the code under test destroy it. The destructor will automatically verify it.
+
+If you follow the following simple rules, your mocks and threads can
+live happily together:
+
+ * Execute your _test code_ (as opposed to the code being tested) in _one_ thread. This makes your test easy to follow.
+ * Obviously, you can do step #1 without locking.
+ * When doing step #2 and #5, make sure no other thread is accessing `foo`. Obvious too, huh?
+ * #3 and #4 can be done either in one thread or in multiple threads - anyway you want. Google Mock takes care of the locking, so you don't have to do any - unless required by your test logic.
+
+If you violate the rules (for example, if you set expectations on a
+mock while another thread is calling its methods), you get undefined
+behavior. That's not fun, so don't do it.
+
+Google Mock guarantees that the action for a mock function is done in
+the same thread that called the mock function. For example, in
+
+```
+ EXPECT_CALL(mock, Foo(1))
+ .WillOnce(action1);
+ EXPECT_CALL(mock, Foo(2))
+ .WillOnce(action2);
+```
+
+if `Foo(1)` is called in thread 1 and `Foo(2)` is called in thread 2,
+Google Mock will execute `action1` in thread 1 and `action2` in thread
+2.
+
+Google Mock does _not_ impose a sequence on actions performed in
+different threads (doing so may create deadlocks as the actions may
+need to cooperate). This means that the execution of `action1` and
+`action2` in the above example _may_ interleave. If this is a problem,
+you should add proper synchronization logic to `action1` and `action2`
+to make the test thread-safe.
+
+
+Also, remember that `DefaultValue<T>` is a global resource that
+potentially affects _all_ living mock objects in your
+program. Naturally, you won't want to mess with it from multiple
+threads or when there still are mocks in action.
+
+## Controlling How Much Information Google Mock Prints ##
+
+When Google Mock sees something that has the potential of being an
+error (e.g. a mock function with no expectation is called, a.k.a. an
+uninteresting call, which is allowed but perhaps you forgot to
+explicitly ban the call), it prints some warning messages, including
+the arguments of the function and the return value. Hopefully this
+will remind you to take a look and see if there is indeed a problem.
+
+Sometimes you are confident that your tests are correct and may not
+appreciate such friendly messages. Some other times, you are debugging
+your tests or learning about the behavior of the code you are testing,
+and wish you could observe every mock call that happens (including
+argument values and the return value). Clearly, one size doesn't fit
+all.
+
+You can control how much Google Mock tells you using the
+`--gmock_verbose=LEVEL` command-line flag, where `LEVEL` is a string
+with three possible values:
+
+ * `info`: Google Mock will print all informational messages, warnings, and errors (most verbose). At this setting, Google Mock will also log any calls to the `ON_CALL/EXPECT_CALL` macros.
+ * `warning`: Google Mock will print both warnings and errors (less verbose). This is the default.
+ * `error`: Google Mock will print errors only (least verbose).
+
+Alternatively, you can adjust the value of that flag from within your
+tests like so:
+
+```
+ ::testing::FLAGS_gmock_verbose = "error";
+```
+
+Now, judiciously use the right flag to enable Google Mock serve you better!
+
+## Gaining Super Vision into Mock Calls ##
+
+You have a test using Google Mock. It fails: Google Mock tells you
+that some expectations aren't satisfied. However, you aren't sure why:
+Is there a typo somewhere in the matchers? Did you mess up the order
+of the `EXPECT_CALL`s? Or is the code under test doing something
+wrong? How can you find out the cause?
+
+Won't it be nice if you have X-ray vision and can actually see the
+trace of all `EXPECT_CALL`s and mock method calls as they are made?
+For each call, would you like to see its actual argument values and
+which `EXPECT_CALL` Google Mock thinks it matches?
+
+You can unlock this power by running your test with the
+`--gmock_verbose=info` flag. For example, given the test program:
+
+```
+using testing::_;
+using testing::HasSubstr;
+using testing::Return;
+
+class MockFoo {
+ public:
+ MOCK_METHOD2(F, void(const string& x, const string& y));
+};
+
+TEST(Foo, Bar) {
+ MockFoo mock;
+ EXPECT_CALL(mock, F(_, _)).WillRepeatedly(Return());
+ EXPECT_CALL(mock, F("a", "b"));
+ EXPECT_CALL(mock, F("c", HasSubstr("d")));
+
+ mock.F("a", "good");
+ mock.F("a", "b");
+}
+```
+
+if you run it with `--gmock_verbose=info`, you will see this output:
+
+```
+[ RUN ] Foo.Bar
+
+foo_test.cc:14: EXPECT_CALL(mock, F(_, _)) invoked
+foo_test.cc:15: EXPECT_CALL(mock, F("a", "b")) invoked
+foo_test.cc:16: EXPECT_CALL(mock, F("c", HasSubstr("d"))) invoked
+foo_test.cc:14: Mock function call matches EXPECT_CALL(mock, F(_, _))...
+ Function call: F(@0x7fff7c8dad40"a", @0x7fff7c8dad10"good")
+foo_test.cc:15: Mock function call matches EXPECT_CALL(mock, F("a", "b"))...
+ Function call: F(@0x7fff7c8dada0"a", @0x7fff7c8dad70"b")
+foo_test.cc:16: Failure
+Actual function call count doesn't match EXPECT_CALL(mock, F("c", HasSubstr("d")))...
+ Expected: to be called once
+ Actual: never called - unsatisfied and active
+[ FAILED ] Foo.Bar
+```
+
+Suppose the bug is that the `"c"` in the third `EXPECT_CALL` is a typo
+and should actually be `"a"`. With the above message, you should see
+that the actual `F("a", "good")` call is matched by the first
+`EXPECT_CALL`, not the third as you thought. From that it should be
+obvious that the third `EXPECT_CALL` is written wrong. Case solved.
+
+## Running Tests in Emacs ##
+
+If you build and run your tests in Emacs, the source file locations of
+Google Mock and [Google Test](../../googletest/)
+errors will be highlighted. Just press `<Enter>` on one of them and
+you'll be taken to the offending line. Or, you can just type `C-x ``
+to jump to the next error.
+
+To make it even easier, you can add the following lines to your
+`~/.emacs` file:
+
+```
+(global-set-key "\M-m" 'compile) ; m is for make
+(global-set-key [M-down] 'next-error)
+(global-set-key [M-up] '(lambda () (interactive) (next-error -1)))
+```
+
+Then you can type `M-m` to start a build, or `M-up`/`M-down` to move
+back and forth between errors.
+
+## Fusing Google Mock Source Files ##
+
+Google Mock's implementation consists of dozens of files (excluding
+its own tests). Sometimes you may want them to be packaged up in
+fewer files instead, such that you can easily copy them to a new
+machine and start hacking there. For this we provide an experimental
+Python script `fuse_gmock_files.py` in the `scripts/` directory
+(starting with release 1.2.0). Assuming you have Python 2.4 or above
+installed on your machine, just go to that directory and run
+```
+python fuse_gmock_files.py OUTPUT_DIR
+```
+
+and you should see an `OUTPUT_DIR` directory being created with files
+`gtest/gtest.h`, `gmock/gmock.h`, and `gmock-gtest-all.cc` in it.
+These three files contain everything you need to use Google Mock (and
+Google Test). Just copy them to anywhere you want and you are ready
+to write tests and use mocks. You can use the
+[scrpts/test/Makefile](../scripts/test/Makefile) file as an example on how to compile your tests
+against them.
+
+# Extending Google Mock #
+
+## Writing New Matchers Quickly ##
+
+The `MATCHER*` family of macros can be used to define custom matchers
+easily. The syntax:
+
+```
+MATCHER(name, description_string_expression) { statements; }
+```
+
+will define a matcher with the given name that executes the
+statements, which must return a `bool` to indicate if the match
+succeeds. Inside the statements, you can refer to the value being
+matched by `arg`, and refer to its type by `arg_type`.
+
+The description string is a `string`-typed expression that documents
+what the matcher does, and is used to generate the failure message
+when the match fails. It can (and should) reference the special
+`bool` variable `negation`, and should evaluate to the description of
+the matcher when `negation` is `false`, or that of the matcher's
+negation when `negation` is `true`.
+
+For convenience, we allow the description string to be empty (`""`),
+in which case Google Mock will use the sequence of words in the
+matcher name as the description.
+
+For example:
+```
+MATCHER(IsDivisibleBy7, "") { return (arg % 7) == 0; }
+```
+allows you to write
+```
+ // Expects mock_foo.Bar(n) to be called where n is divisible by 7.
+ EXPECT_CALL(mock_foo, Bar(IsDivisibleBy7()));
+```
+or,
+```
+using ::testing::Not;
+...
+ EXPECT_THAT(some_expression, IsDivisibleBy7());
+ EXPECT_THAT(some_other_expression, Not(IsDivisibleBy7()));
+```
+If the above assertions fail, they will print something like:
+```
+ Value of: some_expression
+ Expected: is divisible by 7
+ Actual: 27
+...
+ Value of: some_other_expression
+ Expected: not (is divisible by 7)
+ Actual: 21
+```
+where the descriptions `"is divisible by 7"` and `"not (is divisible
+by 7)"` are automatically calculated from the matcher name
+`IsDivisibleBy7`.
+
+As you may have noticed, the auto-generated descriptions (especially
+those for the negation) may not be so great. You can always override
+them with a string expression of your own:
+```
+MATCHER(IsDivisibleBy7, std::string(negation ? "isn't" : "is") +
+ " divisible by 7") {
+ return (arg % 7) == 0;
+}
+```
+
+Optionally, you can stream additional information to a hidden argument
+named `result_listener` to explain the match result. For example, a
+better definition of `IsDivisibleBy7` is:
+```
+MATCHER(IsDivisibleBy7, "") {
+ if ((arg % 7) == 0)
+ return true;
+
+ *result_listener << "the remainder is " << (arg % 7);
+ return false;
+}
+```
+
+With this definition, the above assertion will give a better message:
+```
+ Value of: some_expression
+ Expected: is divisible by 7
+ Actual: 27 (the remainder is 6)
+```
+
+You should let `MatchAndExplain()` print _any additional information_
+that can help a user understand the match result. Note that it should
+explain why the match succeeds in case of a success (unless it's
+obvious) - this is useful when the matcher is used inside
+`Not()`. There is no need to print the argument value itself, as
+Google Mock already prints it for you.
+
+**Notes:**
+
+ 1. The type of the value being matched (`arg_type`) is determined by the context in which you use the matcher and is supplied to you by the compiler, so you don't need to worry about declaring it (nor can you). This allows the matcher to be polymorphic. For example, `IsDivisibleBy7()` can be used to match any type where the value of `(arg % 7) == 0` can be implicitly converted to a `bool`. In the `Bar(IsDivisibleBy7())` example above, if method `Bar()` takes an `int`, `arg_type` will be `int`; if it takes an `unsigned long`, `arg_type` will be `unsigned long`; and so on.
+ 1. Google Mock doesn't guarantee when or how many times a matcher will be invoked. Therefore the matcher logic must be _purely functional_ (i.e. it cannot have any side effect, and the result must not depend on anything other than the value being matched and the matcher parameters). This requirement must be satisfied no matter how you define the matcher (e.g. using one of the methods described in the following recipes). In particular, a matcher can never call a mock function, as that will affect the state of the mock object and Google Mock.
+
+## Writing New Parameterized Matchers Quickly ##
+
+Sometimes you'll want to define a matcher that has parameters. For that you
+can use the macro:
+```
+MATCHER_P(name, param_name, description_string) { statements; }
+```
+where the description string can be either `""` or a string expression
+that references `negation` and `param_name`.
+
+For example:
+```
+MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
+```
+will allow you to write:
+```
+ EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
+```
+which may lead to this message (assuming `n` is 10):
+```
+ Value of: Blah("a")
+ Expected: has absolute value 10
+ Actual: -9
+```
+
+Note that both the matcher description and its parameter are
+printed, making the message human-friendly.
+
+In the matcher definition body, you can write `foo_type` to
+reference the type of a parameter named `foo`. For example, in the
+body of `MATCHER_P(HasAbsoluteValue, value)` above, you can write
+`value_type` to refer to the type of `value`.
+
+Google Mock also provides `MATCHER_P2`, `MATCHER_P3`, ..., up to
+`MATCHER_P10` to support multi-parameter matchers:
+```
+MATCHER_Pk(name, param_1, ..., param_k, description_string) { statements; }
+```
+
+Please note that the custom description string is for a particular
+**instance** of the matcher, where the parameters have been bound to
+actual values. Therefore usually you'll want the parameter values to
+be part of the description. Google Mock lets you do that by
+referencing the matcher parameters in the description string
+expression.
+
+For example,
+```
+ using ::testing::PrintToString;
+ MATCHER_P2(InClosedRange, low, hi,
+ std::string(negation ? "isn't" : "is") + " in range [" +
+ PrintToString(low) + ", " + PrintToString(hi) + "]") {
+ return low <= arg && arg <= hi;
+ }
+ ...
+ EXPECT_THAT(3, InClosedRange(4, 6));
+```
+would generate a failure that contains the message:
+```
+ Expected: is in range [4, 6]
+```
+
+If you specify `""` as the description, the failure message will
+contain the sequence of words in the matcher name followed by the
+parameter values printed as a tuple. For example,
+```
+ MATCHER_P2(InClosedRange, low, hi, "") { ... }
+ ...
+ EXPECT_THAT(3, InClosedRange(4, 6));
+```
+would generate a failure that contains the text:
+```
+ Expected: in closed range (4, 6)
+```
+
+For the purpose of typing, you can view
+```
+MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
+```
+as shorthand for
+```
+template <typename p1_type, ..., typename pk_type>
+FooMatcherPk<p1_type, ..., pk_type>
+Foo(p1_type p1, ..., pk_type pk) { ... }
+```
+
+When you write `Foo(v1, ..., vk)`, the compiler infers the types of
+the parameters `v1`, ..., and `vk` for you. If you are not happy with
+the result of the type inference, you can specify the types by
+explicitly instantiating the template, as in `Foo<long, bool>(5, false)`.
+As said earlier, you don't get to (or need to) specify
+`arg_type` as that's determined by the context in which the matcher
+is used.
+
+You can assign the result of expression `Foo(p1, ..., pk)` to a
+variable of type `FooMatcherPk<p1_type, ..., pk_type>`. This can be
+useful when composing matchers. Matchers that don't have a parameter
+or have only one parameter have special types: you can assign `Foo()`
+to a `FooMatcher`-typed variable, and assign `Foo(p)` to a
+`FooMatcherP<p_type>`-typed variable.
+
+While you can instantiate a matcher template with reference types,
+passing the parameters by pointer usually makes your code more
+readable. If, however, you still want to pass a parameter by
+reference, be aware that in the failure message generated by the
+matcher you will see the value of the referenced object but not its
+address.
+
+You can overload matchers with different numbers of parameters:
+```
+MATCHER_P(Blah, a, description_string_1) { ... }
+MATCHER_P2(Blah, a, b, description_string_2) { ... }
+```
+
+While it's tempting to always use the `MATCHER*` macros when defining
+a new matcher, you should also consider implementing
+`MatcherInterface` or using `MakePolymorphicMatcher()` instead (see
+the recipes that follow), especially if you need to use the matcher a
+lot. While these approaches require more work, they give you more
+control on the types of the value being matched and the matcher
+parameters, which in general leads to better compiler error messages
+that pay off in the long run. They also allow overloading matchers
+based on parameter types (as opposed to just based on the number of
+parameters).
+
+## Writing New Monomorphic Matchers ##
+
+A matcher of argument type `T` implements
+`::testing::MatcherInterface<T>` and does two things: it tests whether a
+value of type `T` matches the matcher, and can describe what kind of
+values it matches. The latter ability is used for generating readable
+error messages when expectations are violated.
+
+The interface looks like this:
+
+```
+class MatchResultListener {
+ public:
+ ...
+ // Streams x to the underlying ostream; does nothing if the ostream
+ // is NULL.
+ template <typename T>
+ MatchResultListener& operator<<(const T& x);
+
+ // Returns the underlying ostream.
+ ::std::ostream* stream();
+};
+
+template <typename T>
+class MatcherInterface {
+ public:
+ virtual ~MatcherInterface();
+
+ // Returns true iff the matcher matches x; also explains the match
+ // result to 'listener'.
+ virtual bool MatchAndExplain(T x, MatchResultListener* listener) const = 0;
+
+ // Describes this matcher to an ostream.
+ virtual void DescribeTo(::std::ostream* os) const = 0;
+
+ // Describes the negation of this matcher to an ostream.
+ virtual void DescribeNegationTo(::std::ostream* os) const;
+};
+```
+
+If you need a custom matcher but `Truly()` is not a good option (for
+example, you may not be happy with the way `Truly(predicate)`
+describes itself, or you may want your matcher to be polymorphic as
+`Eq(value)` is), you can define a matcher to do whatever you want in
+two steps: first implement the matcher interface, and then define a
+factory function to create a matcher instance. The second step is not
+strictly needed but it makes the syntax of using the matcher nicer.
+
+For example, you can define a matcher to test whether an `int` is
+divisible by 7 and then use it like this:
+```
+using ::testing::MakeMatcher;
+using ::testing::Matcher;
+using ::testing::MatcherInterface;
+using ::testing::MatchResultListener;
+
+class DivisibleBy7Matcher : public MatcherInterface<int> {
+ public:
+ virtual bool MatchAndExplain(int n, MatchResultListener* listener) const {
+ return (n % 7) == 0;
+ }
+
+ virtual void DescribeTo(::std::ostream* os) const {
+ *os << "is divisible by 7";
+ }
+
+ virtual void DescribeNegationTo(::std::ostream* os) const {
+ *os << "is not divisible by 7";
+ }
+};
+
+inline Matcher<int> DivisibleBy7() {
+ return MakeMatcher(new DivisibleBy7Matcher);
+}
+...
+
+ EXPECT_CALL(foo, Bar(DivisibleBy7()));
+```
+
+You may improve the matcher message by streaming additional
+information to the `listener` argument in `MatchAndExplain()`:
+
+```
+class DivisibleBy7Matcher : public MatcherInterface<int> {
+ public:
+ virtual bool MatchAndExplain(int n,
+ MatchResultListener* listener) const {
+ const int remainder = n % 7;
+ if (remainder != 0) {
+ *listener << "the remainder is " << remainder;
+ }
+ return remainder == 0;
+ }
+ ...
+};
+```
+
+Then, `EXPECT_THAT(x, DivisibleBy7());` may general a message like this:
+```
+Value of: x
+Expected: is divisible by 7
+ Actual: 23 (the remainder is 2)
+```
+
+## Writing New Polymorphic Matchers ##
+
+You've learned how to write your own matchers in the previous
+recipe. Just one problem: a matcher created using `MakeMatcher()` only
+works for one particular type of arguments. If you want a
+_polymorphic_ matcher that works with arguments of several types (for
+instance, `Eq(x)` can be used to match a `value` as long as `value` ==
+`x` compiles -- `value` and `x` don't have to share the same type),
+you can learn the trick from `"gmock/gmock-matchers.h"` but it's a bit
+involved.
+
+Fortunately, most of the time you can define a polymorphic matcher
+easily with the help of `MakePolymorphicMatcher()`. Here's how you can
+define `NotNull()` as an example:
+
+```
+using ::testing::MakePolymorphicMatcher;
+using ::testing::MatchResultListener;
+using ::testing::NotNull;
+using ::testing::PolymorphicMatcher;
+
+class NotNullMatcher {
+ public:
+ // To implement a polymorphic matcher, first define a COPYABLE class
+ // that has three members MatchAndExplain(), DescribeTo(), and
+ // DescribeNegationTo(), like the following.
+
+ // In this example, we want to use NotNull() with any pointer, so
+ // MatchAndExplain() accepts a pointer of any type as its first argument.
+ // In general, you can define MatchAndExplain() as an ordinary method or
+ // a method template, or even overload it.
+ template <typename T>
+ bool MatchAndExplain(T* p,
+ MatchResultListener* /* listener */) const {
+ return p != NULL;
+ }
+
+ // Describes the property of a value matching this matcher.
+ void DescribeTo(::std::ostream* os) const { *os << "is not NULL"; }
+
+ // Describes the property of a value NOT matching this matcher.
+ void DescribeNegationTo(::std::ostream* os) const { *os << "is NULL"; }
+};
+
+// To construct a polymorphic matcher, pass an instance of the class
+// to MakePolymorphicMatcher(). Note the return type.
+inline PolymorphicMatcher<NotNullMatcher> NotNull() {
+ return MakePolymorphicMatcher(NotNullMatcher());
+}
+...
+
+ EXPECT_CALL(foo, Bar(NotNull())); // The argument must be a non-NULL pointer.
+```
+
+**Note:** Your polymorphic matcher class does **not** need to inherit from
+`MatcherInterface` or any other class, and its methods do **not** need
+to be virtual.
+
+Like in a monomorphic matcher, you may explain the match result by
+streaming additional information to the `listener` argument in
+`MatchAndExplain()`.
+
+## Writing New Cardinalities ##
+
+A cardinality is used in `Times()` to tell Google Mock how many times
+you expect a call to occur. It doesn't have to be exact. For example,
+you can say `AtLeast(5)` or `Between(2, 4)`.
+
+If the built-in set of cardinalities doesn't suit you, you are free to
+define your own by implementing the following interface (in namespace
+`testing`):
+
+```
+class CardinalityInterface {
+ public:
+ virtual ~CardinalityInterface();
+
+ // Returns true iff call_count calls will satisfy this cardinality.
+ virtual bool IsSatisfiedByCallCount(int call_count) const = 0;
+
+ // Returns true iff call_count calls will saturate this cardinality.
+ virtual bool IsSaturatedByCallCount(int call_count) const = 0;
+
+ // Describes self to an ostream.
+ virtual void DescribeTo(::std::ostream* os) const = 0;
+};
+```
+
+For example, to specify that a call must occur even number of times,
+you can write
+
+```
+using ::testing::Cardinality;
+using ::testing::CardinalityInterface;
+using ::testing::MakeCardinality;
+
+class EvenNumberCardinality : public CardinalityInterface {
+ public:
+ virtual bool IsSatisfiedByCallCount(int call_count) const {
+ return (call_count % 2) == 0;
+ }
+
+ virtual bool IsSaturatedByCallCount(int call_count) const {
+ return false;
+ }
+
+ virtual void DescribeTo(::std::ostream* os) const {
+ *os << "called even number of times";
+ }
+};
+
+Cardinality EvenNumber() {
+ return MakeCardinality(new EvenNumberCardinality);
+}
+...
+
+ EXPECT_CALL(foo, Bar(3))
+ .Times(EvenNumber());
+```
+
+## Writing New Actions Quickly ##
+
+If the built-in actions don't work for you, and you find it
+inconvenient to use `Invoke()`, you can use a macro from the `ACTION*`
+family to quickly define a new action that can be used in your code as
+if it's a built-in action.
+
+By writing
+```
+ACTION(name) { statements; }
+```
+in a namespace scope (i.e. not inside a class or function), you will
+define an action with the given name that executes the statements.
+The value returned by `statements` will be used as the return value of
+the action. Inside the statements, you can refer to the K-th
+(0-based) argument of the mock function as `argK`. For example:
+```
+ACTION(IncrementArg1) { return ++(*arg1); }
+```
+allows you to write
+```
+... WillOnce(IncrementArg1());
+```
+
+Note that you don't need to specify the types of the mock function
+arguments. Rest assured that your code is type-safe though:
+you'll get a compiler error if `*arg1` doesn't support the `++`
+operator, or if the type of `++(*arg1)` isn't compatible with the mock
+function's return type.
+
+Another example:
+```
+ACTION(Foo) {
+ (*arg2)(5);
+ Blah();
+ *arg1 = 0;
+ return arg0;
+}
+```
+defines an action `Foo()` that invokes argument #2 (a function pointer)
+with 5, calls function `Blah()`, sets the value pointed to by argument
+#1 to 0, and returns argument #0.
+
+For more convenience and flexibility, you can also use the following
+pre-defined symbols in the body of `ACTION`:
+
+| `argK_type` | The type of the K-th (0-based) argument of the mock function |
+|:------------|:-------------------------------------------------------------|
+| `args` | All arguments of the mock function as a tuple |
+| `args_type` | The type of all arguments of the mock function as a tuple |
+| `return_type` | The return type of the mock function |
+| `function_type` | The type of the mock function |
+
+For example, when using an `ACTION` as a stub action for mock function:
+```
+int DoSomething(bool flag, int* ptr);
+```
+we have:
+
+| **Pre-defined Symbol** | **Is Bound To** |
+|:-----------------------|:----------------|
+| `arg0` | the value of `flag` |
+| `arg0_type` | the type `bool` |
+| `arg1` | the value of `ptr` |
+| `arg1_type` | the type `int*` |
+| `args` | the tuple `(flag, ptr)` |
+| `args_type` | the type `::testing::tuple<bool, int*>` |
+| `return_type` | the type `int` |
+| `function_type` | the type `int(bool, int*)` |
+
+## Writing New Parameterized Actions Quickly ##
+
+Sometimes you'll want to parameterize an action you define. For that
+we have another macro
+```
+ACTION_P(name, param) { statements; }
+```
+
+For example,
+```
+ACTION_P(Add, n) { return arg0 + n; }
+```
+will allow you to write
+```
+// Returns argument #0 + 5.
+... WillOnce(Add(5));
+```
+
+For convenience, we use the term _arguments_ for the values used to
+invoke the mock function, and the term _parameters_ for the values
+used to instantiate an action.
+
+Note that you don't need to provide the type of the parameter either.
+Suppose the parameter is named `param`, you can also use the
+Google-Mock-defined symbol `param_type` to refer to the type of the
+parameter as inferred by the compiler. For example, in the body of
+`ACTION_P(Add, n)` above, you can write `n_type` for the type of `n`.
+
+Google Mock also provides `ACTION_P2`, `ACTION_P3`, and etc to support
+multi-parameter actions. For example,
+```
+ACTION_P2(ReturnDistanceTo, x, y) {
+ double dx = arg0 - x;
+ double dy = arg1 - y;
+ return sqrt(dx*dx + dy*dy);
+}
+```
+lets you write
+```
+... WillOnce(ReturnDistanceTo(5.0, 26.5));
+```
+
+You can view `ACTION` as a degenerated parameterized action where the
+number of parameters is 0.
+
+You can also easily define actions overloaded on the number of parameters:
+```
+ACTION_P(Plus, a) { ... }
+ACTION_P2(Plus, a, b) { ... }
+```
+
+## Restricting the Type of an Argument or Parameter in an ACTION ##
+
+For maximum brevity and reusability, the `ACTION*` macros don't ask
+you to provide the types of the mock function arguments and the action
+parameters. Instead, we let the compiler infer the types for us.
+
+Sometimes, however, we may want to be more explicit about the types.
+There are several tricks to do that. For example:
+```
+ACTION(Foo) {
+ // Makes sure arg0 can be converted to int.
+ int n = arg0;
+ ... use n instead of arg0 here ...
+}
+
+ACTION_P(Bar, param) {
+ // Makes sure the type of arg1 is const char*.
+ ::testing::StaticAssertTypeEq<const char*, arg1_type>();
+
+ // Makes sure param can be converted to bool.
+ bool flag = param;
+}
+```
+where `StaticAssertTypeEq` is a compile-time assertion in Google Test
+that verifies two types are the same.
+
+## Writing New Action Templates Quickly ##
+
+Sometimes you want to give an action explicit template parameters that
+cannot be inferred from its value parameters. `ACTION_TEMPLATE()`
+supports that and can be viewed as an extension to `ACTION()` and
+`ACTION_P*()`.
+
+The syntax:
+```
+ACTION_TEMPLATE(ActionName,
+ HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
+ AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
+```
+
+defines an action template that takes _m_ explicit template parameters
+and _n_ value parameters, where _m_ is between 1 and 10, and _n_ is
+between 0 and 10. `name_i` is the name of the i-th template
+parameter, and `kind_i` specifies whether it's a `typename`, an
+integral constant, or a template. `p_i` is the name of the i-th value
+parameter.
+
+Example:
+```
+// DuplicateArg<k, T>(output) converts the k-th argument of the mock
+// function to type T and copies it to *output.
+ACTION_TEMPLATE(DuplicateArg,
+ // Note the comma between int and k:
+ HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
+ AND_1_VALUE_PARAMS(output)) {
+ *output = T(::testing::get<k>(args));
+}
+```
+
+To create an instance of an action template, write:
+```
+ ActionName<t1, ..., t_m>(v1, ..., v_n)
+```
+where the `t`s are the template arguments and the
+`v`s are the value arguments. The value argument
+types are inferred by the compiler. For example:
+```
+using ::testing::_;
+...
+ int n;
+ EXPECT_CALL(mock, Foo(_, _))
+ .WillOnce(DuplicateArg<1, unsigned char>(&n));
+```
+
+If you want to explicitly specify the value argument types, you can
+provide additional template arguments:
+```
+ ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
+```
+where `u_i` is the desired type of `v_i`.
+
+`ACTION_TEMPLATE` and `ACTION`/`ACTION_P*` can be overloaded on the
+number of value parameters, but not on the number of template
+parameters. Without the restriction, the meaning of the following is
+unclear:
+
+```
+ OverloadedAction<int, bool>(x);
+```
+
+Are we using a single-template-parameter action where `bool` refers to
+the type of `x`, or a two-template-parameter action where the compiler
+is asked to infer the type of `x`?
+
+## Using the ACTION Object's Type ##
+
+If you are writing a function that returns an `ACTION` object, you'll
+need to know its type. The type depends on the macro used to define
+the action and the parameter types. The rule is relatively simple:
+
+| **Given Definition** | **Expression** | **Has Type** |
+|:---------------------|:---------------|:-------------|
+| `ACTION(Foo)` | `Foo()` | `FooAction` |
+| `ACTION_TEMPLATE(Foo, HAS_m_TEMPLATE_PARAMS(...), AND_0_VALUE_PARAMS())` | `Foo<t1, ..., t_m>()` | `FooAction<t1, ..., t_m>` |
+| `ACTION_P(Bar, param)` | `Bar(int_value)` | `BarActionP<int>` |
+| `ACTION_TEMPLATE(Bar, HAS_m_TEMPLATE_PARAMS(...), AND_1_VALUE_PARAMS(p1))` | `Bar<t1, ..., t_m>(int_value)` | `FooActionP<t1, ..., t_m, int>` |
+| `ACTION_P2(Baz, p1, p2)` | `Baz(bool_value, int_value)` | `BazActionP2<bool, int>` |
+| `ACTION_TEMPLATE(Baz, HAS_m_TEMPLATE_PARAMS(...), AND_2_VALUE_PARAMS(p1, p2))`| `Baz<t1, ..., t_m>(bool_value, int_value)` | `FooActionP2<t1, ..., t_m, bool, int>` |
+| ... | ... | ... |
+
+Note that we have to pick different suffixes (`Action`, `ActionP`,
+`ActionP2`, and etc) for actions with different numbers of value
+parameters, or the action definitions cannot be overloaded on the
+number of them.
+
+## Writing New Monomorphic Actions ##
+
+While the `ACTION*` macros are very convenient, sometimes they are
+inappropriate. For example, despite the tricks shown in the previous
+recipes, they don't let you directly specify the types of the mock
+function arguments and the action parameters, which in general leads
+to unoptimized compiler error messages that can baffle unfamiliar
+users. They also don't allow overloading actions based on parameter
+types without jumping through some hoops.
+
+An alternative to the `ACTION*` macros is to implement
+`::testing::ActionInterface<F>`, where `F` is the type of the mock
+function in which the action will be used. For example:
+
+```
+template <typename F>class ActionInterface {
+ public:
+ virtual ~ActionInterface();
+
+ // Performs the action. Result is the return type of function type
+ // F, and ArgumentTuple is the tuple of arguments of F.
+ //
+ // For example, if F is int(bool, const string&), then Result would
+ // be int, and ArgumentTuple would be ::testing::tuple<bool, const string&>.
+ virtual Result Perform(const ArgumentTuple& args) = 0;
+};
+
+using ::testing::_;
+using ::testing::Action;
+using ::testing::ActionInterface;
+using ::testing::MakeAction;
+
+typedef int IncrementMethod(int*);
+
+class IncrementArgumentAction : public ActionInterface<IncrementMethod> {
+ public:
+ virtual int Perform(const ::testing::tuple<int*>& args) {
+ int* p = ::testing::get<0>(args); // Grabs the first argument.
+ return *p++;
+ }
+};
+
+Action<IncrementMethod> IncrementArgument() {
+ return MakeAction(new IncrementArgumentAction);
+}
+...
+
+ EXPECT_CALL(foo, Baz(_))
+ .WillOnce(IncrementArgument());
+
+ int n = 5;
+ foo.Baz(&n); // Should return 5 and change n to 6.
+```
+
+## Writing New Polymorphic Actions ##
+
+The previous recipe showed you how to define your own action. This is
+all good, except that you need to know the type of the function in
+which the action will be used. Sometimes that can be a problem. For
+example, if you want to use the action in functions with _different_
+types (e.g. like `Return()` and `SetArgPointee()`).
+
+If an action can be used in several types of mock functions, we say
+it's _polymorphic_. The `MakePolymorphicAction()` function template
+makes it easy to define such an action:
+
+```
+namespace testing {
+
+template <typename Impl>
+PolymorphicAction<Impl> MakePolymorphicAction(const Impl& impl);
+
+} // namespace testing
+```
+
+As an example, let's define an action that returns the second argument
+in the mock function's argument list. The first step is to define an
+implementation class:
+
+```
+class ReturnSecondArgumentAction {
+ public:
+ template <typename Result, typename ArgumentTuple>
+ Result Perform(const ArgumentTuple& args) const {
+ // To get the i-th (0-based) argument, use ::testing::get<i>(args).
+ return ::testing::get<1>(args);
+ }
+};
+```
+
+This implementation class does _not_ need to inherit from any
+particular class. What matters is that it must have a `Perform()`
+method template. This method template takes the mock function's
+arguments as a tuple in a **single** argument, and returns the result of
+the action. It can be either `const` or not, but must be invokable
+with exactly one template argument, which is the result type. In other
+words, you must be able to call `Perform<R>(args)` where `R` is the
+mock function's return type and `args` is its arguments in a tuple.
+
+Next, we use `MakePolymorphicAction()` to turn an instance of the
+implementation class into the polymorphic action we need. It will be
+convenient to have a wrapper for this:
+
+```
+using ::testing::MakePolymorphicAction;
+using ::testing::PolymorphicAction;
+
+PolymorphicAction<ReturnSecondArgumentAction> ReturnSecondArgument() {
+ return MakePolymorphicAction(ReturnSecondArgumentAction());
+}
+```
+
+Now, you can use this polymorphic action the same way you use the
+built-in ones:
+
+```
+using ::testing::_;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD2(DoThis, int(bool flag, int n));
+ MOCK_METHOD3(DoThat, string(int x, const char* str1, const char* str2));
+};
+...
+
+ MockFoo foo;
+ EXPECT_CALL(foo, DoThis(_, _))
+ .WillOnce(ReturnSecondArgument());
+ EXPECT_CALL(foo, DoThat(_, _, _))
+ .WillOnce(ReturnSecondArgument());
+ ...
+ foo.DoThis(true, 5); // Will return 5.
+ foo.DoThat(1, "Hi", "Bye"); // Will return "Hi".
+```
+
+## Teaching Google Mock How to Print Your Values ##
+
+When an uninteresting or unexpected call occurs, Google Mock prints the
+argument values and the stack trace to help you debug. Assertion
+macros like `EXPECT_THAT` and `EXPECT_EQ` also print the values in
+question when the assertion fails. Google Mock and Google Test do this using
+Google Test's user-extensible value printer.
+
+This printer knows how to print built-in C++ types, native arrays, STL
+containers, and any type that supports the `<<` operator. For other
+types, it prints the raw bytes in the value and hopes that you the
+user can figure it out.
+[Google Test's advanced guide](../../googletest/docs/AdvancedGuide.md#teaching-google-test-how-to-print-your-values)
+explains how to extend the printer to do a better job at
+printing your particular type than to dump the bytes.

+
+# Macros for Defining Actions #
+
+## Problem ##
+
+Due to the lack of closures in C++, it currently requires some
+non-trivial effort to define a custom action in Google Mock. For
+example, suppose you want to "increment the value pointed to by the
+second argument of the mock function and return it", you could write:
+
+```
+int IncrementArg1(Unused, int* p, Unused) {
+ return ++(*p);
+}
+
+... WillOnce(Invoke(IncrementArg1));
+```
+
+There are several things unsatisfactory about this approach:
+
+ * Even though the action only cares about the second argument of the mock function, its definition needs to list other arguments as dummies. This is tedious.
+ * The defined action is usable only in mock functions that takes exactly 3 arguments - an unnecessary restriction.
+ * To use the action, one has to say `Invoke(IncrementArg1)`, which isn't as nice as `IncrementArg1()`.
+
+The latter two problems can be overcome using `MakePolymorphicAction()`,
+but it requires much more boilerplate code:
+
+```
+class IncrementArg1Action {
+ public:
+ template <typename Result, typename ArgumentTuple>
+ Result Perform(const ArgumentTuple& args) const {
+ return ++(*tr1::get<1>(args));
+ }
+};
+
+PolymorphicAction<IncrementArg1Action> IncrementArg1() {
+ return MakePolymorphicAction(IncrementArg1Action());
+}
+
+... WillOnce(IncrementArg1());
+```
+
+Our goal is to allow defining custom actions with the least amount of
+boiler-plate C++ requires.
+
+## Solution ##
+
+We propose to introduce a new macro:
+```
+ACTION(name) { statements; }
+```
+
+Using this in a namespace scope will define an action with the given
+name that executes the statements. Inside the statements, you can
+refer to the K-th (0-based) argument of the mock function as `argK`.
+For example:
+```
+ACTION(IncrementArg1) { return ++(*arg1); }
+```
+allows you to write
+```
+... WillOnce(IncrementArg1());
+```
+
+Note that you don't need to specify the types of the mock function
+arguments, as brevity is a top design goal here. Rest assured that
+your code is still type-safe though: you'll get a compiler error if
+`*arg1` doesn't support the `++` operator, or if the type of
+`++(*arg1)` isn't compatible with the mock function's return type.
+
+Another example:
+```
+ACTION(Foo) {
+ (*arg2)(5);
+ Blah();
+ *arg1 = 0;
+ return arg0;
+}
+```
+defines an action `Foo()` that invokes argument #2 (a function pointer)
+with 5, calls function `Blah()`, sets the value pointed to by argument
+#1 to 0, and returns argument #0.
+
+For more convenience and flexibility, you can also use the following
+pre-defined symbols in the body of `ACTION`:
+
+| `argK_type` | The type of the K-th (0-based) argument of the mock function |
+|:------------|:-------------------------------------------------------------|
+| `args` | All arguments of the mock function as a tuple |
+| `args_type` | The type of all arguments of the mock function as a tuple |
+| `return_type` | The return type of the mock function |
+| `function_type` | The type of the mock function |
+
+For example, when using an `ACTION` as a stub action for mock function:
+```
+int DoSomething(bool flag, int* ptr);
+```
+we have:
+| **Pre-defined Symbol** | **Is Bound To** |
+|:-----------------------|:----------------|
+| `arg0` | the value of `flag` |
+| `arg0_type` | the type `bool` |
+| `arg1` | the value of `ptr` |
+| `arg1_type` | the type `int*` |
+| `args` | the tuple `(flag, ptr)` |
+| `args_type` | the type `std::tr1::tuple<bool, int*>` |
+| `return_type` | the type `int` |
+| `function_type` | the type `int(bool, int*)` |
+
+## Parameterized actions ##
+
+Sometimes you'll want to parameterize the action. For that we propose
+another macro
+```
+ACTION_P(name, param) { statements; }
+```
+
+For example,
+```
+ACTION_P(Add, n) { return arg0 + n; }
+```
+will allow you to write
+```
+// Returns argument #0 + 5.
+... WillOnce(Add(5));
+```
+
+For convenience, we use the term _arguments_ for the values used to
+invoke the mock function, and the term _parameters_ for the values
+used to instantiate an action.
+
+Note that you don't need to provide the type of the parameter either.
+Suppose the parameter is named `param`, you can also use the
+Google-Mock-defined symbol `param_type` to refer to the type of the
+parameter as inferred by the compiler.
+
+We will also provide `ACTION_P2`, `ACTION_P3`, and etc to support
+multi-parameter actions. For example,
+```
+ACTION_P2(ReturnDistanceTo, x, y) {
+ double dx = arg0 - x;
+ double dy = arg1 - y;
+ return sqrt(dx*dx + dy*dy);
+}
+```
+lets you write
+```
+... WillOnce(ReturnDistanceTo(5.0, 26.5));
+```
+
+You can view `ACTION` as a degenerated parameterized action where the
+number of parameters is 0.
+
+## Advanced Usages ##
+
+### Overloading Actions ###
+
+You can easily define actions overloaded on the number of parameters:
+```
+ACTION_P(Plus, a) { ... }
+ACTION_P2(Plus, a, b) { ... }
+```
+
+### Restricting the Type of an Argument or Parameter ###
+
+For maximum brevity and reusability, the `ACTION*` macros don't let
+you specify the types of the mock function arguments and the action
+parameters. Instead, we let the compiler infer the types for us.
+
+Sometimes, however, we may want to be more explicit about the types.
+There are several tricks to do that. For example:
+```
+ACTION(Foo) {
+ // Makes sure arg0 can be converted to int.
+ int n = arg0;
+ ... use n instead of arg0 here ...
+}
+
+ACTION_P(Bar, param) {
+ // Makes sure the type of arg1 is const char*.
+ ::testing::StaticAssertTypeEq<const char*, arg1_type>();
+
+ // Makes sure param can be converted to bool.
+ bool flag = param;
+}
+```
+where `StaticAssertTypeEq` is a compile-time assertion we plan to add to
+Google Test (the name is chosen to match `static_assert` in C++0x).
+
+### Using the ACTION Object's Type ###
+
+If you are writing a function that returns an `ACTION` object, you'll
+need to know its type. The type depends on the macro used to define
+the action and the parameter types. The rule is relatively simple:
+| **Given Definition** | **Expression** | **Has Type** |
+|:---------------------|:---------------|:-------------|
+| `ACTION(Foo)` | `Foo()` | `FooAction` |
+| `ACTION_P(Bar, param)` | `Bar(int_value)` | `BarActionP<int>` |
+| `ACTION_P2(Baz, p1, p2)` | `Baz(bool_value, int_value)` | `BazActionP2<bool, int>` |
+| ... | ... | ... |
+
+Note that we have to pick different suffixes (`Action`, `ActionP`,
+`ActionP2`, and etc) for actions with different numbers of parameters,
+or the action definitions cannot be overloaded on the number of
+parameters.
+
+## When to Use ##
+
+While the new macros are very convenient, please also consider other
+means of implementing actions (e.g. via `ActionInterface` or
+`MakePolymorphicAction()`), especially if you need to use the defined
+action a lot. While the other approaches require more work, they give
+you more control on the types of the mock function arguments and the
+action parameters, which in general leads to better compiler error
+messages that pay off in the long run. They also allow overloading
+actions based on parameter types, as opposed to just the number of
+parameters.
+
+## Related Work ##
+
+As you may have realized, the `ACTION*` macros resemble closures (also
+known as lambda expressions or anonymous functions). Indeed, both of
+them seek to lower the syntactic overhead for defining a function.
+
+C++0x will support lambdas, but they are not part of C++ right now.
+Some non-standard libraries (most notably BLL or Boost Lambda Library)
+try to alleviate this problem. However, they are not a good choice
+for defining actions as:
+
+ * They are non-standard and not widely installed. Google Mock only depends on standard libraries and `tr1::tuple`, which is part of the new C++ standard and comes with gcc 4+. We want to keep it that way.
+ * They are not trivial to learn.
+ * They will become obsolete when C++0x's lambda feature is widely supported. We don't want to make our users use a dying library.
+ * Since they are based on operators, they are rather ad hoc: you cannot use statements, and you cannot pass the lambda arguments to a function, for example.
+ * They have subtle semantics that easily confuses new users. For example, in expression `_1++ + foo++`, `foo` will be incremented only once where the expression is evaluated, while `_1` will be incremented every time the unnamed function is invoked. This is far from intuitive.
+
+`ACTION*` avoid all these problems.
+
+## Future Improvements ##
+
+There may be a need for composing `ACTION*` definitions (i.e. invoking
+another `ACTION` inside the definition of one `ACTION*`). We are not
+sure we want it yet, as one can get a similar effect by putting
+`ACTION` definitions in function templates and composing the function
+templates. We'll revisit this based on user feedback.
+
+The reason we don't allow `ACTION*()` inside a function body is that
+the current C++ standard doesn't allow function-local types to be used
+to instantiate templates. The upcoming C++0x standard will lift this
+restriction. Once this feature is widely supported by compilers, we
+can revisit the implementation and add support for using `ACTION*()`
+inside a function.
+
+C++0x will also support lambda expressions. When they become
+available, we may want to support using lambdas as actions.
+
+# Macros for Defining Matchers #
+
+Once the macros for defining actions are implemented, we plan to do
+the same for matchers:
+
+```
+MATCHER(name) { statements; }
+```
+
+where you can refer to the value being matched as `arg`. For example,
+given:
+
+```
+MATCHER(IsPositive) { return arg > 0; }
+```
+
+you can use `IsPositive()` as a matcher that matches a value iff it is
+greater than 0.
+
+We will also add `MATCHER_P`, `MATCHER_P2`, and etc for parameterized
+matchers.

+
+# What Is Google C++ Mocking Framework? #
+When you write a prototype or test, often it's not feasible or wise to rely on real objects entirely. A **mock object** implements the same interface as a real object (so it can be used as one), but lets you specify at run time how it will be used and what it should do (which methods will be called? in which order? how many times? with what arguments? what will they return? etc).
+
+**Note:** It is easy to confuse the term _fake objects_ with mock objects. Fakes and mocks actually mean very different things in the Test-Driven Development (TDD) community:
+
+ * **Fake** objects have working implementations, but usually take some shortcut (perhaps to make the operations less expensive), which makes them not suitable for production. An in-memory file system would be an example of a fake.
+ * **Mocks** are objects pre-programmed with _expectations_, which form a specification of the calls they are expected to receive.
+
+If all this seems too abstract for you, don't worry - the most important thing to remember is that a mock allows you to check the _interaction_ between itself and code that uses it. The difference between fakes and mocks will become much clearer once you start to use mocks.
+
+**Google C++ Mocking Framework** (or **Google Mock** for short) is a library (sometimes we also call it a "framework" to make it sound cool) for creating mock classes and using them. It does to C++ what [jMock](http://www.jmock.org/) and [EasyMock](http://www.easymock.org/) do to Java.
+
+Using Google Mock involves three basic steps:
+
+ 1. Use some simple macros to describe the interface you want to mock, and they will expand to the implementation of your mock class;
+ 1. Create some mock objects and specify its expectations and behavior using an intuitive syntax;
+ 1. Exercise code that uses the mock objects. Google Mock will catch any violation of the expectations as soon as it arises.
+
+# Why Google Mock? #
+While mock objects help you remove unnecessary dependencies in tests and make them fast and reliable, using mocks manually in C++ is _hard_:
+
+ * Someone has to implement the mocks. The job is usually tedious and error-prone. No wonder people go great distances to avoid it.
+ * The quality of those manually written mocks is a bit, uh, unpredictable. You may see some really polished ones, but you may also see some that were hacked up in a hurry and have all sorts of ad-hoc restrictions.
+ * The knowledge you gained from using one mock doesn't transfer to the next.
+
+In contrast, Java and Python programmers have some fine mock frameworks, which automate the creation of mocks. As a result, mocking is a proven effective technique and widely adopted practice in those communities. Having the right tool absolutely makes the difference.
+
+Google Mock was built to help C++ programmers. It was inspired by [jMock](http://www.jmock.org/) and [EasyMock](http://www.easymock.org/), but designed with C++'s specifics in mind. It is your friend if any of the following problems is bothering you:
+
+ * You are stuck with a sub-optimal design and wish you had done more prototyping before it was too late, but prototyping in C++ is by no means "rapid".
+ * Your tests are slow as they depend on too many libraries or use expensive resources (e.g. a database).
+ * Your tests are brittle as some resources they use are unreliable (e.g. the network).
+ * You want to test how your code handles a failure (e.g. a file checksum error), but it's not easy to cause one.
+ * You need to make sure that your module interacts with other modules in the right way, but it's hard to observe the interaction; therefore you resort to observing the side effects at the end of the action, which is awkward at best.
+ * You want to "mock out" your dependencies, except that they don't have mock implementations yet; and, frankly, you aren't thrilled by some of those hand-written mocks.
+
+We encourage you to use Google Mock as:

+
+# Getting Started #
+Using Google Mock is easy! Inside your C++ source file, just `#include` `"gtest/gtest.h"` and `"gmock/gmock.h"`, and you are ready to go.
+
+# A Case for Mock Turtles #
+Let's look at an example. Suppose you are developing a graphics program that relies on a LOGO-like API for drawing. How would you test that it does the right thing? Well, you can run it and compare the screen with a golden screen snapshot, but let's admit it: tests like this are expensive to run and fragile (What if you just upgraded to a shiny new graphics card that has better anti-aliasing? Suddenly you have to update all your golden images.). It would be too painful if all your tests are like this. Fortunately, you learned about Dependency Injection and know the right thing to do: instead of having your application talk to the drawing API directly, wrap the API in an interface (say, `Turtle`) and code to that interface:
+
+```
+class Turtle {
+ ...
+ virtual ~Turtle() {}
+ virtual void PenUp() = 0;
+ virtual void PenDown() = 0;
+ virtual void Forward(int distance) = 0;
+ virtual void Turn(int degrees) = 0;
+ virtual void GoTo(int x, int y) = 0;
+ virtual int GetX() const = 0;
+ virtual int GetY() const = 0;
+};
+```
+
+(Note that the destructor of `Turtle` **must** be virtual, as is the case for **all** classes you intend to inherit from - otherwise the destructor of the derived class will not be called when you delete an object through a base pointer, and you'll get corrupted program states like memory leaks.)
+
+You can control whether the turtle's movement will leave a trace using `PenUp()` and `PenDown()`, and control its movement using `Forward()`, `Turn()`, and `GoTo()`. Finally, `GetX()` and `GetY()` tell you the current position of the turtle.
+
+Your program will normally use a real implementation of this interface. In tests, you can use a mock implementation instead. This allows you to easily check what drawing primitives your program is calling, with what arguments, and in which order. Tests written this way are much more robust (they won't break because your new machine does anti-aliasing differently), easier to read and maintain (the intent of a test is expressed in the code, not in some binary images), and run _much, much faster_.
+
+# Writing the Mock Class #
+If you are lucky, the mocks you need to use have already been implemented by some nice people. If, however, you find yourself in the position to write a mock class, relax - Google Mock turns this task into a fun game! (Well, almost.)
+
+## How to Define It ##
+Using the `Turtle` interface as example, here are the simple steps you need to follow:
+
+ 1. Derive a class `MockTurtle` from `Turtle`.
+ 1. Take a _virtual_ function of `Turtle` (while it's possible to [mock non-virtual methods using templates](CookBook.md#mocking-nonvirtual-methods), it's much more involved). Count how many arguments it has.
+ 1. In the `public:` section of the child class, write `MOCK_METHODn();` (or `MOCK_CONST_METHODn();` if you are mocking a `const` method), where `n` is the number of the arguments; if you counted wrong, shame on you, and a compiler error will tell you so.
+ 1. Now comes the fun part: you take the function signature, cut-and-paste the _function name_ as the _first_ argument to the macro, and leave what's left as the _second_ argument (in case you're curious, this is the _type of the function_).
+ 1. Repeat until all virtual functions you want to mock are done.
+
+After the process, you should have something like:
+
+```
+#include "gmock/gmock.h" // Brings in Google Mock.
+class MockTurtle : public Turtle {
+ public:
+ ...
+ MOCK_METHOD0(PenUp, void());
+ MOCK_METHOD0(PenDown, void());
+ MOCK_METHOD1(Forward, void(int distance));
+ MOCK_METHOD1(Turn, void(int degrees));
+ MOCK_METHOD2(GoTo, void(int x, int y));
+ MOCK_CONST_METHOD0(GetX, int());
+ MOCK_CONST_METHOD0(GetY, int());
+};
+```
+
+You don't need to define these mock methods somewhere else - the `MOCK_METHOD*` macros will generate the definitions for you. It's that simple! Once you get the hang of it, you can pump out mock classes faster than your source-control system can handle your check-ins.
+
+**Tip:** If even this is too much work for you, you'll find the
+`gmock_gen.py` tool in Google Mock's `scripts/generator/` directory (courtesy of the [cppclean](http://code.google.com/p/cppclean/) project) useful. This command-line
+tool requires that you have Python 2.4 installed. You give it a C++ file and the name of an abstract class defined in it,
+and it will print the definition of the mock class for you. Due to the
+complexity of the C++ language, this script may not always work, but
+it can be quite handy when it does. For more details, read the [user documentation](../scripts/generator/README).
+
+## Where to Put It ##
+When you define a mock class, you need to decide where to put its definition. Some people put it in a `*_test.cc`. This is fine when the interface being mocked (say, `Foo`) is owned by the same person or team. Otherwise, when the owner of `Foo` changes it, your test could break. (You can't really expect `Foo`'s maintainer to fix every test that uses `Foo`, can you?)
+
+So, the rule of thumb is: if you need to mock `Foo` and it's owned by others, define the mock class in `Foo`'s package (better, in a `testing` sub-package such that you can clearly separate production code and testing utilities), and put it in a `mock_foo.h`. Then everyone can reference `mock_foo.h` from their tests. If `Foo` ever changes, there is only one copy of `MockFoo` to change, and only tests that depend on the changed methods need to be fixed.
+
+Another way to do it: you can introduce a thin layer `FooAdaptor` on top of `Foo` and code to this new interface. Since you own `FooAdaptor`, you can absorb changes in `Foo` much more easily. While this is more work initially, carefully choosing the adaptor interface can make your code easier to write and more readable (a net win in the long run), as you can choose `FooAdaptor` to fit your specific domain much better than `Foo` does.
+
+# Using Mocks in Tests #
+Once you have a mock class, using it is easy. The typical work flow is:
+
+ 1. Import the Google Mock names from the `testing` namespace such that you can use them unqualified (You only have to do it once per file. Remember that namespaces are a good idea and good for your health.).
+ 1. Create some mock objects.
+ 1. Specify your expectations on them (How many times will a method be called? With what arguments? What should it do? etc.).
+ 1. Exercise some code that uses the mocks; optionally, check the result using Google Test assertions. If a mock method is called more than expected or with wrong arguments, you'll get an error immediately.
+ 1. When a mock is destructed, Google Mock will automatically check whether all expectations on it have been satisfied.
+
+Here's an example:
+
+```
+#include "path/to/mock-turtle.h"
+#include "gmock/gmock.h"
+#include "gtest/gtest.h"
+using ::testing::AtLeast; // #1
+
+TEST(PainterTest, CanDrawSomething) {
+ MockTurtle turtle; // #2
+ EXPECT_CALL(turtle, PenDown()) // #3
+ .Times(AtLeast(1));
+
+ Painter painter(&turtle); // #4
+
+ EXPECT_TRUE(painter.DrawCircle(0, 0, 10));
+} // #5
+
+int main(int argc, char** argv) {
+ // The following line must be executed to initialize Google Mock
+ // (and Google Test) before running the tests.
+ ::testing::InitGoogleMock(&argc, argv);
+ return RUN_ALL_TESTS();
+}
+```
+
+As you might have guessed, this test checks that `PenDown()` is called at least once. If the `painter` object didn't call this method, your test will fail with a message like this:
+
+```
+path/to/my_test.cc:119: Failure
+Actual function call count doesn't match this expectation:
+Actually: never called;
+Expected: called at least once.
+```
+
+**Tip 1:** If you run the test from an Emacs buffer, you can hit `<Enter>` on the line number displayed in the error message to jump right to the failed expectation.
+
+**Tip 2:** If your mock objects are never deleted, the final verification won't happen. Therefore it's a good idea to use a heap leak checker in your tests when you allocate mocks on the heap.
+
+**Important note:** Google Mock requires expectations to be set **before** the mock functions are called, otherwise the behavior is **undefined**. In particular, you mustn't interleave `EXPECT_CALL()`s and calls to the mock functions.
+
+This means `EXPECT_CALL()` should be read as expecting that a call will occur _in the future_, not that a call has occurred. Why does Google Mock work like that? Well, specifying the expectation beforehand allows Google Mock to report a violation as soon as it arises, when the context (stack trace, etc) is still available. This makes debugging much easier.
+
+Admittedly, this test is contrived and doesn't do much. You can easily achieve the same effect without using Google Mock. However, as we shall reveal soon, Google Mock allows you to do _much more_ with the mocks.
+
+## Using Google Mock with Any Testing Framework ##
+If you want to use something other than Google Test (e.g. [CppUnit](http://sourceforge.net/projects/cppunit/) or
+[CxxTest](http://cxxtest.tigris.org/)) as your testing framework, just change the `main()` function in the previous section to:
+```
+int main(int argc, char** argv) {
+ // The following line causes Google Mock to throw an exception on failure,
+ // which will be interpreted by your testing framework as a test failure.
+ ::testing::GTEST_FLAG(throw_on_failure) = true;
+ ::testing::InitGoogleMock(&argc, argv);
+ ... whatever your testing framework requires ...
+}
+```
+
+This approach has a catch: it makes Google Mock throw an exception
+from a mock object's destructor sometimes. With some compilers, this
+sometimes causes the test program to crash. You'll still be able to
+notice that the test has failed, but it's not a graceful failure.
+
+A better solution is to use Google Test's
+[event listener API](../../googletest/docs/AdvancedGuide.md#extending-google-test-by-handling-test-events)
+to report a test failure to your testing framework properly. You'll need to
+implement the `OnTestPartResult()` method of the event listener interface, but it
+should be straightforward.
+
+If this turns out to be too much work, we suggest that you stick with
+Google Test, which works with Google Mock seamlessly (in fact, it is
+technically part of Google Mock.). If there is a reason that you
+cannot use Google Test, please let us know.
+
+# Setting Expectations #
+The key to using a mock object successfully is to set the _right expectations_ on it. If you set the expectations too strict, your test will fail as the result of unrelated changes. If you set them too loose, bugs can slip through. You want to do it just right such that your test can catch exactly the kind of bugs you intend it to catch. Google Mock provides the necessary means for you to do it "just right."
+
+## General Syntax ##
+In Google Mock we use the `EXPECT_CALL()` macro to set an expectation on a mock method. The general syntax is:
+
+```
+EXPECT_CALL(mock_object, method(matchers))
+ .Times(cardinality)
+ .WillOnce(action)
+ .WillRepeatedly(action);
+```
+
+The macro has two arguments: first the mock object, and then the method and its arguments. Note that the two are separated by a comma (`,`), not a period (`.`). (Why using a comma? The answer is that it was necessary for technical reasons.)
+
+The macro can be followed by some optional _clauses_ that provide more information about the expectation. We'll discuss how each clause works in the coming sections.
+
+This syntax is designed to make an expectation read like English. For example, you can probably guess that
+
+```
+using ::testing::Return;
+...
+EXPECT_CALL(turtle, GetX())
+ .Times(5)
+ .WillOnce(Return(100))
+ .WillOnce(Return(150))
+ .WillRepeatedly(Return(200));
+```
+
+says that the `turtle` object's `GetX()` method will be called five times, it will return 100 the first time, 150 the second time, and then 200 every time. Some people like to call this style of syntax a Domain-Specific Language (DSL).
+
+**Note:** Why do we use a macro to do this? It serves two purposes: first it makes expectations easily identifiable (either by `grep` or by a human reader), and second it allows Google Mock to include the source file location of a failed expectation in messages, making debugging easier.
+
+## Matchers: What Arguments Do We Expect? ##
+When a mock function takes arguments, we must specify what arguments we are expecting; for example:
+
+```
+// Expects the turtle to move forward by 100 units.
+EXPECT_CALL(turtle, Forward(100));
+```
+
+Sometimes you may not want to be too specific (Remember that talk about tests being too rigid? Over specification leads to brittle tests and obscures the intent of tests. Therefore we encourage you to specify only what's necessary - no more, no less.). If you care to check that `Forward()` will be called but aren't interested in its actual argument, write `_` as the argument, which means "anything goes":
+
+```
+using ::testing::_;
+...
+// Expects the turtle to move forward.
+EXPECT_CALL(turtle, Forward(_));
+```
+
+`_` is an instance of what we call **matchers**. A matcher is like a predicate and can test whether an argument is what we'd expect. You can use a matcher inside `EXPECT_CALL()` wherever a function argument is expected.
+
+A list of built-in matchers can be found in the [CheatSheet](CheatSheet.md). For example, here's the `Ge` (greater than or equal) matcher:
+
+```
+using ::testing::Ge;
+...
+EXPECT_CALL(turtle, Forward(Ge(100)));
+```
+
+This checks that the turtle will be told to go forward by at least 100 units.
+
+## Cardinalities: How Many Times Will It Be Called? ##
+The first clause we can specify following an `EXPECT_CALL()` is `Times()`. We call its argument a **cardinality** as it tells _how many times_ the call should occur. It allows us to repeat an expectation many times without actually writing it as many times. More importantly, a cardinality can be "fuzzy", just like a matcher can be. This allows a user to express the intent of a test exactly.
+
+An interesting special case is when we say `Times(0)`. You may have guessed - it means that the function shouldn't be called with the given arguments at all, and Google Mock will report a Google Test failure whenever the function is (wrongfully) called.
+
+We've seen `AtLeast(n)` as an example of fuzzy cardinalities earlier. For the list of built-in cardinalities you can use, see the [CheatSheet](CheatSheet.md).
+
+The `Times()` clause can be omitted. **If you omit `Times()`, Google Mock will infer the cardinality for you.** The rules are easy to remember:
+
+ * If **neither** `WillOnce()` **nor** `WillRepeatedly()` is in the `EXPECT_CALL()`, the inferred cardinality is `Times(1)`.
+ * If there are `n WillOnce()`'s but **no** `WillRepeatedly()`, where `n` >= 1, the cardinality is `Times(n)`.
+ * If there are `n WillOnce()`'s and **one** `WillRepeatedly()`, where `n` >= 0, the cardinality is `Times(AtLeast(n))`.
+
+**Quick quiz:** what do you think will happen if a function is expected to be called twice but actually called four times?
+
+## Actions: What Should It Do? ##
+Remember that a mock object doesn't really have a working implementation? We as users have to tell it what to do when a method is invoked. This is easy in Google Mock.
+
+First, if the return type of a mock function is a built-in type or a pointer, the function has a **default action** (a `void` function will just return, a `bool` function will return `false`, and other functions will return 0). In addition, in C++ 11 and above, a mock function whose return type is default-constructible (i.e. has a default constructor) has a default action of returning a default-constructed value. If you don't say anything, this behavior will be used.
+
+Second, if a mock function doesn't have a default action, or the default action doesn't suit you, you can specify the action to be taken each time the expectation matches using a series of `WillOnce()` clauses followed by an optional `WillRepeatedly()`. For example,
+
+```
+using ::testing::Return;
+...
+EXPECT_CALL(turtle, GetX())
+ .WillOnce(Return(100))
+ .WillOnce(Return(200))
+ .WillOnce(Return(300));
+```
+
+This says that `turtle.GetX()` will be called _exactly three times_ (Google Mock inferred this from how many `WillOnce()` clauses we've written, since we didn't explicitly write `Times()`), and will return 100, 200, and 300 respectively.
+
+```
+using ::testing::Return;
+...
+EXPECT_CALL(turtle, GetY())
+ .WillOnce(Return(100))
+ .WillOnce(Return(200))
+ .WillRepeatedly(Return(300));
+```
+
+says that `turtle.GetY()` will be called _at least twice_ (Google Mock knows this as we've written two `WillOnce()` clauses and a `WillRepeatedly()` while having no explicit `Times()`), will return 100 the first time, 200 the second time, and 300 from the third time on.
+
+Of course, if you explicitly write a `Times()`, Google Mock will not try to infer the cardinality itself. What if the number you specified is larger than there are `WillOnce()` clauses? Well, after all `WillOnce()`s are used up, Google Mock will do the _default_ action for the function every time (unless, of course, you have a `WillRepeatedly()`.).
+
+What can we do inside `WillOnce()` besides `Return()`? You can return a reference using `ReturnRef(variable)`, or invoke a pre-defined function, among [others](CheatSheet.md#actions).
+
+**Important note:** The `EXPECT_CALL()` statement evaluates the action clause only once, even though the action may be performed many times. Therefore you must be careful about side effects. The following may not do what you want:
+
+```
+int n = 100;
+EXPECT_CALL(turtle, GetX())
+.Times(4)
+.WillRepeatedly(Return(n++));
+```
+
+Instead of returning 100, 101, 102, ..., consecutively, this mock function will always return 100 as `n++` is only evaluated once. Similarly, `Return(new Foo)` will create a new `Foo` object when the `EXPECT_CALL()` is executed, and will return the same pointer every time. If you want the side effect to happen every time, you need to define a custom action, which we'll teach in the [CookBook](CookBook.md).
+
+Time for another quiz! What do you think the following means?
+
+```
+using ::testing::Return;
+...
+EXPECT_CALL(turtle, GetY())
+.Times(4)
+.WillOnce(Return(100));
+```
+
+Obviously `turtle.GetY()` is expected to be called four times. But if you think it will return 100 every time, think twice! Remember that one `WillOnce()` clause will be consumed each time the function is invoked and the default action will be taken afterwards. So the right answer is that `turtle.GetY()` will return 100 the first time, but **return 0 from the second time on**, as returning 0 is the default action for `int` functions.
+
+## Using Multiple Expectations ##
+So far we've only shown examples where you have a single expectation. More realistically, you're going to specify expectations on multiple mock methods, which may be from multiple mock objects.
+
+By default, when a mock method is invoked, Google Mock will search the expectations in the **reverse order** they are defined, and stop when an active expectation that matches the arguments is found (you can think of it as "newer rules override older ones."). If the matching expectation cannot take any more calls, you will get an upper-bound-violated failure. Here's an example:
+
+```
+using ::testing::_;
+...
+EXPECT_CALL(turtle, Forward(_)); // #1
+EXPECT_CALL(turtle, Forward(10)) // #2
+ .Times(2);
+```
+
+If `Forward(10)` is called three times in a row, the third time it will be an error, as the last matching expectation (#2) has been saturated. If, however, the third `Forward(10)` call is replaced by `Forward(20)`, then it would be OK, as now #1 will be the matching expectation.
+
+**Side note:** Why does Google Mock search for a match in the _reverse_ order of the expectations? The reason is that this allows a user to set up the default expectations in a mock object's constructor or the test fixture's set-up phase and then customize the mock by writing more specific expectations in the test body. So, if you have two expectations on the same method, you want to put the one with more specific matchers **after** the other, or the more specific rule would be shadowed by the more general one that comes after it.
+
+## Ordered vs Unordered Calls ##
+By default, an expectation can match a call even though an earlier expectation hasn't been satisfied. In other words, the calls don't have to occur in the order the expectations are specified.
+
+Sometimes, you may want all the expected calls to occur in a strict order. To say this in Google Mock is easy:
+
+```
+using ::testing::InSequence;
+...
+TEST(FooTest, DrawsLineSegment) {
+ ...
+ {
+ InSequence dummy;
+
+ EXPECT_CALL(turtle, PenDown());
+ EXPECT_CALL(turtle, Forward(100));
+ EXPECT_CALL(turtle, PenUp());
+ }
+ Foo();
+}
+```
+
+By creating an object of type `InSequence`, all expectations in its scope are put into a _sequence_ and have to occur _sequentially_. Since we are just relying on the constructor and destructor of this object to do the actual work, its name is really irrelevant.
+
+In this example, we test that `Foo()` calls the three expected functions in the order as written. If a call is made out-of-order, it will be an error.
+
+(What if you care about the relative order of some of the calls, but not all of them? Can you specify an arbitrary partial order? The answer is ... yes! If you are impatient, the details can be found in the [CookBook](CookBook.md#expecting-partially-ordered-calls).)
+
+## All Expectations Are Sticky (Unless Said Otherwise) ##
+Now let's do a quick quiz to see how well you can use this mock stuff already. How would you test that the turtle is asked to go to the origin _exactly twice_ (you want to ignore any other instructions it receives)?
+
+After you've come up with your answer, take a look at ours and compare notes (solve it yourself first - don't cheat!):
+
+```
+using ::testing::_;
+...
+EXPECT_CALL(turtle, GoTo(_, _)) // #1
+ .Times(AnyNumber());
+EXPECT_CALL(turtle, GoTo(0, 0)) // #2
+ .Times(2);
+```
+
+Suppose `turtle.GoTo(0, 0)` is called three times. In the third time, Google Mock will see that the arguments match expectation #2 (remember that we always pick the last matching expectation). Now, since we said that there should be only two such calls, Google Mock will report an error immediately. This is basically what we've told you in the "Using Multiple Expectations" section above.
+
+This example shows that **expectations in Google Mock are "sticky" by default**, in the sense that they remain active even after we have reached their invocation upper bounds. This is an important rule to remember, as it affects the meaning of the spec, and is **different** to how it's done in many other mocking frameworks (Why'd we do that? Because we think our rule makes the common cases easier to express and understand.).
+
+Simple? Let's see if you've really understood it: what does the following code say?
+
+```
+using ::testing::Return;
+...
+for (int i = n; i > 0; i--) {
+ EXPECT_CALL(turtle, GetX())
+ .WillOnce(Return(10*i));
+}
+```
+
+If you think it says that `turtle.GetX()` will be called `n` times and will return 10, 20, 30, ..., consecutively, think twice! The problem is that, as we said, expectations are sticky. So, the second time `turtle.GetX()` is called, the last (latest) `EXPECT_CALL()` statement will match, and will immediately lead to an "upper bound exceeded" error - this piece of code is not very useful!
+
+One correct way of saying that `turtle.GetX()` will return 10, 20, 30, ..., is to explicitly say that the expectations are _not_ sticky. In other words, they should _retire_ as soon as they are saturated:
+
+```
+using ::testing::Return;
+...
+for (int i = n; i > 0; i--) {
+ EXPECT_CALL(turtle, GetX())
+ .WillOnce(Return(10*i))
+ .RetiresOnSaturation();
+}
+```
+
+And, there's a better way to do it: in this case, we expect the calls to occur in a specific order, and we line up the actions to match the order. Since the order is important here, we should make it explicit using a sequence:
+
+```
+using ::testing::InSequence;
+using ::testing::Return;
+...
+{
+ InSequence s;
+
+ for (int i = 1; i <= n; i++) {
+ EXPECT_CALL(turtle, GetX())
+ .WillOnce(Return(10*i))
+ .RetiresOnSaturation();
+ }
+}
+```
+
+By the way, the other situation where an expectation may _not_ be sticky is when it's in a sequence - as soon as another expectation that comes after it in the sequence has been used, it automatically retires (and will never be used to match any call).
+
+## Uninteresting Calls ##
+A mock object may have many methods, and not all of them are that interesting. For example, in some tests we may not care about how many times `GetX()` and `GetY()` get called.
+
+In Google Mock, if you are not interested in a method, just don't say anything about it. If a call to this method occurs, you'll see a warning in the test output, but it won't be a failure.
+
+# What Now? #
+Congratulations! You've learned enough about Google Mock to start using it. Now, you might want to join the [googlemock](http://groups.google.com/group/googlemock) discussion group and actually write some tests using Google Mock - it will be fun. Hey, it may even be addictive - you've been warned.
+
+Then, if you feel like increasing your mock quotient, you should move on to the [CookBook](CookBook.md). You can learn many advanced features of Google Mock there -- and advance your level of enjoyment and testing bliss.

+## When I call a method on my mock object, the method for the real object is invoked instead. What's the problem? ##
+
+In order for a method to be mocked, it must be _virtual_, unless you use the [high-perf dependency injection technique](CookBook.md#mocking-nonvirtual-methods).
+
+## I wrote some matchers. After I upgraded to a new version of Google Mock, they no longer compile. What's going on? ##
+
+After version 1.4.0 of Google Mock was released, we had an idea on how
+to make it easier to write matchers that can generate informative
+messages efficiently. We experimented with this idea and liked what
+we saw. Therefore we decided to implement it.
+
+Unfortunately, this means that if you have defined your own matchers
+by implementing `MatcherInterface` or using `MakePolymorphicMatcher()`,
+your definitions will no longer compile. Matchers defined using the
+`MATCHER*` family of macros are not affected.
+
+Sorry for the hassle if your matchers are affected. We believe it's
+in everyone's long-term interest to make this change sooner than
+later. Fortunately, it's usually not hard to migrate an existing
+matcher to the new API. Here's what you need to do:
+
+If you wrote your matcher like this:
+```
+// Old matcher definition that doesn't work with the latest
+// Google Mock.
+using ::testing::MatcherInterface;
+...
+class MyWonderfulMatcher : public MatcherInterface<MyType> {
+ public:
+ ...
+ virtual bool Matches(MyType value) const {
+ // Returns true if value matches.
+ return value.GetFoo() > 5;
+ }
+ ...
+};
+```
+
+you'll need to change it to:
+```
+// New matcher definition that works with the latest Google Mock.
+using ::testing::MatcherInterface;
+using ::testing::MatchResultListener;
+...
+class MyWonderfulMatcher : public MatcherInterface<MyType> {
+ public:
+ ...
+ virtual bool MatchAndExplain(MyType value,
+ MatchResultListener* listener) const {
+ // Returns true if value matches.
+ return value.GetFoo() > 5;
+ }
+ ...
+};
+```
+(i.e. rename `Matches()` to `MatchAndExplain()` and give it a second
+argument of type `MatchResultListener*`.)
+
+If you were also using `ExplainMatchResultTo()` to improve the matcher
+message:
+```
+// Old matcher definition that doesn't work with the lastest
+// Google Mock.
+using ::testing::MatcherInterface;
+...
+class MyWonderfulMatcher : public MatcherInterface<MyType> {
+ public:
+ ...
+ virtual bool Matches(MyType value) const {
+ // Returns true if value matches.
+ return value.GetFoo() > 5;
+ }
+
+ virtual void ExplainMatchResultTo(MyType value,
+ ::std::ostream* os) const {
+ // Prints some helpful information to os to help
+ // a user understand why value matches (or doesn't match).
+ *os << "the Foo property is " << value.GetFoo();
+ }
+ ...
+};
+```
+
+you should move the logic of `ExplainMatchResultTo()` into
+`MatchAndExplain()`, using the `MatchResultListener` argument where
+the `::std::ostream` was used:
+```
+// New matcher definition that works with the latest Google Mock.
+using ::testing::MatcherInterface;
+using ::testing::MatchResultListener;
+...
+class MyWonderfulMatcher : public MatcherInterface<MyType> {
+ public:

+ // Returns true if value matches.
+ *listener << "the Foo property is " << value.GetFoo();
+ return value.GetFoo() > 5;
+ }
+ ...
+};
+```
+
+If your matcher is defined using `MakePolymorphicMatcher()`:
+```
+// Old matcher definition that doesn't work with the latest
+// Google Mock.
+using ::testing::MakePolymorphicMatcher;
+...
+class MyGreatMatcher {
+ public:
+ ...
+ bool Matches(MyType value) const {
+ // Returns true if value matches.
+ return value.GetBar() < 42;
+ }
+ ...
+};
+... MakePolymorphicMatcher(MyGreatMatcher()) ...
+```
+
+you should rename the `Matches()` method to `MatchAndExplain()` and
+add a `MatchResultListener*` argument (the same as what you need to do
+for matchers defined by implementing `MatcherInterface`):
+```
+// New matcher definition that works with the latest Google Mock.
+using ::testing::MakePolymorphicMatcher;
+using ::testing::MatchResultListener;
+...
+class MyGreatMatcher {
+ public:
+ ...
+ bool MatchAndExplain(MyType value,
+ MatchResultListener* listener) const {
+ // Returns true if value matches.
+ return value.GetBar() < 42;
+ }
+ ...
+};
+... MakePolymorphicMatcher(MyGreatMatcher()) ...
+```
+
+If your polymorphic matcher uses `ExplainMatchResultTo()` for better
+failure messages:
+```
+// Old matcher definition that doesn't work with the latest
+// Google Mock.
+using ::testing::MakePolymorphicMatcher;
+...
+class MyGreatMatcher {
+ public:
+ ...
+ bool Matches(MyType value) const {
+ // Returns true if value matches.
+ return value.GetBar() < 42;
+ }
+ ...
+};
+void ExplainMatchResultTo(const MyGreatMatcher& matcher,
+ MyType value,
+ ::std::ostream* os) {
+ // Prints some helpful information to os to help
+ // a user understand why value matches (or doesn't match).
+ *os << "the Bar property is " << value.GetBar();
+}
+... MakePolymorphicMatcher(MyGreatMatcher()) ...
+```
+
+you'll need to move the logic inside `ExplainMatchResultTo()` to
+`MatchAndExplain()`:
+```
+// New matcher definition that works with the latest Google Mock.
+using ::testing::MakePolymorphicMatcher;
+using ::testing::MatchResultListener;
+...
+class MyGreatMatcher {
+ public:
+ ...
+ bool MatchAndExplain(MyType value,
+ MatchResultListener* listener) const {
+ // Returns true if value matches.
+ *listener << "the Bar property is " << value.GetBar();
+ return value.GetBar() < 42;
+ }
+ ...
+};
+... MakePolymorphicMatcher(MyGreatMatcher()) ...
+```

+
+## When using Google Mock, do I have to use Google Test as the testing framework? I have my favorite testing framework and don't want to switch. ##
+
+Google Mock works out of the box with Google Test. However, it's easy
+to configure it to work with any testing framework of your choice.
+[Here](ForDummies.md#using-google-mock-with-any-testing-framework) is how.
+
+## How am I supposed to make sense of these horrible template errors? ##
+
+If you are confused by the compiler errors gcc threw at you,
+try consulting the _Google Mock Doctor_ tool first. What it does is to
+scan stdin for gcc error messages, and spit out diagnoses on the
+problems (we call them diseases) your code has.
+
+To "install", run command:
+```
+alias gmd='<path to googlemock>/scripts/gmock_doctor.py'
+```
+
+To use it, do:
+```
+<your-favorite-build-command> <your-test> 2>&1 | gmd
+```
+
+For example:
+```
+make my_test 2>&1 | gmd
+```
+
+Or you can run `gmd` and copy-n-paste gcc's error messages to it.
+
+## Can I mock a variadic function? ##
+
+You cannot mock a variadic function (i.e. a function taking ellipsis
+(`...`) arguments) directly in Google Mock.
+
+The problem is that in general, there is _no way_ for a mock object to
+know how many arguments are passed to the variadic method, and what
+the arguments' types are. Only the _author of the base class_ knows
+the protocol, and we cannot look into their head.
+
+Therefore, to mock such a function, the _user_ must teach the mock
+object how to figure out the number of arguments and their types. One
+way to do it is to provide overloaded versions of the function.
+
+Ellipsis arguments are inherited from C and not really a C++ feature.
+They are unsafe to use and don't work with arguments that have
+constructors or destructors. Therefore we recommend to avoid them in
+C++ as much as possible.
+
+## MSVC gives me warning C4301 or C4373 when I define a mock method with a const parameter. Why? ##
+
+If you compile this using Microsoft Visual C++ 2005 SP1:
+```
+class Foo {
+ ...
+ virtual void Bar(const int i) = 0;
+};
+
+class MockFoo : public Foo {
+ ...
+ MOCK_METHOD1(Bar, void(const int i));
+};
+```
+You may get the following warning:
+```
+warning C4301: 'MockFoo::Bar': overriding virtual function only differs from 'Foo::Bar' by const/volatile qualifier
+```
+
+This is a MSVC bug. The same code compiles fine with gcc ,for
+example. If you use Visual C++ 2008 SP1, you would get the warning:
+```
+warning C4373: 'MockFoo::Bar': virtual function overrides 'Foo::Bar', previous versions of the compiler did not override when parameters only differed by const/volatile qualifiers
+```
+
+In C++, if you _declare_ a function with a `const` parameter, the
+`const` modifier is _ignored_. Therefore, the `Foo` base class above
+is equivalent to:
+```
+class Foo {
+ ...
+ virtual void Bar(int i) = 0; // int or const int? Makes no difference.
+};
+```
+
+In fact, you can _declare_ Bar() with an `int` parameter, and _define_
+it with a `const int` parameter. The compiler will still match them
+up.
+
+Since making a parameter `const` is meaningless in the method
+_declaration_, we recommend to remove it in both `Foo` and `MockFoo`.
+That should workaround the VC bug.
+
+Note that we are talking about the _top-level_ `const` modifier here.
+If the function parameter is passed by pointer or reference, declaring
+the _pointee_ or _referee_ as `const` is still meaningful. For
+example, the following two declarations are _not_ equivalent:
+```
+void Bar(int* p); // Neither p nor *p is const.
+void Bar(const int* p); // p is not const, but *p is.
+```
+
+## I have a huge mock class, and Microsoft Visual C++ runs out of memory when compiling it. What can I do? ##
+
+We've noticed that when the `/clr` compiler flag is used, Visual C++
+uses 5~6 times as much memory when compiling a mock class. We suggest
+to avoid `/clr` when compiling native C++ mocks.
+
+## I can't figure out why Google Mock thinks my expectations are not satisfied. What should I do? ##
+
+You might want to run your test with
+`--gmock_verbose=info`. This flag lets Google Mock print a trace
+of every mock function call it receives. By studying the trace,
+you'll gain insights on why the expectations you set are not met.
+
+## How can I assert that a function is NEVER called? ##
+
+```
+EXPECT_CALL(foo, Bar(_))
+ .Times(0);
+```
+
+## I have a failed test where Google Mock tells me TWICE that a particular expectation is not satisfied. Isn't this redundant? ##
+
+When Google Mock detects a failure, it prints relevant information
+(the mock function arguments, the state of relevant expectations, and
+etc) to help the user debug. If another failure is detected, Google
+Mock will do the same, including printing the state of relevant
+expectations.
+
+Sometimes an expectation's state didn't change between two failures,
+and you'll see the same description of the state twice. They are
+however _not_ redundant, as they refer to _different points in time_.
+The fact they are the same _is_ interesting information.
+
+## I get a heap check failure when using a mock object, but using a real object is fine. What can be wrong? ##
+
+Does the class (hopefully a pure interface) you are mocking have a
+virtual destructor?
+
+Whenever you derive from a base class, make sure its destructor is
+virtual. Otherwise Bad Things will happen. Consider the following
+code:
+
+```
+class Base {
+ public:
+ // Not virtual, but should be.
+ ~Base() { ... }
+ ...
+};
+
+class Derived : public Base {
+ public:
+ ...
+ private:
+ std::string value_;
+};
+
+...
+ Base* p = new Derived;
+ ...
+ delete p; // Surprise! ~Base() will be called, but ~Derived() will not
+ // - value_ is leaked.
+```
+
+By changing `~Base()` to virtual, `~Derived()` will be correctly
+called when `delete p` is executed, and the heap checker
+will be happy.
+
+## The "newer expectations override older ones" rule makes writing expectations awkward. Why does Google Mock do that? ##
+
+When people complain about this, often they are referring to code like:
+
+```
+// foo.Bar() should be called twice, return 1 the first time, and return
+// 2 the second time. However, I have to write the expectations in the
+// reverse order. This sucks big time!!!
+EXPECT_CALL(foo, Bar())
+ .WillOnce(Return(2))
+ .RetiresOnSaturation();
+EXPECT_CALL(foo, Bar())
+ .WillOnce(Return(1))
+ .RetiresOnSaturation();
+```
+
+The problem is that they didn't pick the **best** way to express the test's
+intent.
+
+By default, expectations don't have to be matched in _any_ particular
+order. If you want them to match in a certain order, you need to be
+explicit. This is Google Mock's (and jMock's) fundamental philosophy: it's
+easy to accidentally over-specify your tests, and we want to make it
+harder to do so.
+
+There are two better ways to write the test spec. You could either
+put the expectations in sequence:
+
+```
+// foo.Bar() should be called twice, return 1 the first time, and return
+// 2 the second time. Using a sequence, we can write the expectations
+// in their natural order.
+{
+ InSequence s;
+ EXPECT_CALL(foo, Bar())
+ .WillOnce(Return(1))
+ .RetiresOnSaturation();
+ EXPECT_CALL(foo, Bar())
+ .WillOnce(Return(2))
+ .RetiresOnSaturation();
+}
+```
+
+or you can put the sequence of actions in the same expectation:
+
+```
+// foo.Bar() should be called twice, return 1 the first time, and return
+// 2 the second time.
+EXPECT_CALL(foo, Bar())
+ .WillOnce(Return(1))
+ .WillOnce(Return(2))
+ .RetiresOnSaturation();
+```
+
+Back to the original questions: why does Google Mock search the
+expectations (and `ON_CALL`s) from back to front? Because this
+allows a user to set up a mock's behavior for the common case early
+(e.g. in the mock's constructor or the test fixture's set-up phase)
+and customize it with more specific rules later. If Google Mock
+searches from front to back, this very useful pattern won't be
+possible.
+
+## Google Mock prints a warning when a function without EXPECT\_CALL is called, even if I have set its behavior using ON\_CALL. Would it be reasonable not to show the warning in this case? ##
+
+When choosing between being neat and being safe, we lean toward the
+latter. So the answer is that we think it's better to show the
+warning.
+
+Often people write `ON_CALL`s in the mock object's
+constructor or `SetUp()`, as the default behavior rarely changes from
+test to test. Then in the test body they set the expectations, which
+are often different for each test. Having an `ON_CALL` in the set-up
+part of a test doesn't mean that the calls are expected. If there's
+no `EXPECT_CALL` and the method is called, it's possibly an error. If
+we quietly let the call go through without notifying the user, bugs
+may creep in unnoticed.
+
+If, however, you are sure that the calls are OK, you can write
+
+```
+EXPECT_CALL(foo, Bar(_))
+ .WillRepeatedly(...);
+```
+
+instead of
+
+```
+ON_CALL(foo, Bar(_))
+ .WillByDefault(...);
+```
+
+This tells Google Mock that you do expect the calls and no warning should be
+printed.
+
+Also, you can control the verbosity using the `--gmock_verbose` flag.
+If you find the output too noisy when debugging, just choose a less
+verbose level.
+
+## How can I delete the mock function's argument in an action? ##
+
+If you find yourself needing to perform some action that's not
+supported by Google Mock directly, remember that you can define your own
+actions using
+[MakeAction()](CookBook.md#writing-new-actions) or
+[MakePolymorphicAction()](CookBook.md#writing_new_polymorphic_actions),
+or you can write a stub function and invoke it using
+[Invoke()](CookBook.md#using-functions_methods_functors).
+
+## MOCK\_METHODn()'s second argument looks funny. Why don't you use the MOCK\_METHODn(Method, return\_type, arg\_1, ..., arg\_n) syntax? ##
+
+What?! I think it's beautiful. :-)
+
+While which syntax looks more natural is a subjective matter to some
+extent, Google Mock's syntax was chosen for several practical advantages it
+has.
+
+Try to mock a function that takes a map as an argument:
+```
+virtual int GetSize(const map<int, std::string>& m);
+```
+
+Using the proposed syntax, it would be:
+```
+MOCK_METHOD1(GetSize, int, const map<int, std::string>& m);
+```
+
+Guess what? You'll get a compiler error as the compiler thinks that
+`const map<int, std::string>& m` are **two**, not one, arguments. To work
+around this you can use `typedef` to give the map type a name, but
+that gets in the way of your work. Google Mock's syntax avoids this
+problem as the function's argument types are protected inside a pair
+of parentheses:
+```
+// This compiles fine.
+MOCK_METHOD1(GetSize, int(const map<int, std::string>& m));
+```
+
+You still need a `typedef` if the return type contains an unprotected
+comma, but that's much rarer.
+
+Other advantages include:
+ 1. `MOCK_METHOD1(Foo, int, bool)` can leave a reader wonder whether the method returns `int` or `bool`, while there won't be such confusion using Google Mock's syntax.
+ 1. The way Google Mock describes a function type is nothing new, although many people may not be familiar with it. The same syntax was used in C, and the `function` library in `tr1` uses this syntax extensively. Since `tr1` will become a part of the new version of STL, we feel very comfortable to be consistent with it.
+ 1. The function type syntax is also used in other parts of Google Mock's API (e.g. the action interface) in order to make the implementation tractable. A user needs to learn it anyway in order to utilize Google Mock's more advanced features. We'd as well stick to the same syntax in `MOCK_METHOD*`!
+
+## My code calls a static/global function. Can I mock it? ##
+
+You can, but you need to make some changes.
+
+In general, if you find yourself needing to mock a static function,
+it's a sign that your modules are too tightly coupled (and less
+flexible, less reusable, less testable, etc). You are probably better
+off defining a small interface and call the function through that
+interface, which then can be easily mocked. It's a bit of work
+initially, but usually pays for itself quickly.
+
+This Google Testing Blog
+[post](http://googletesting.blogspot.com/2008/06/defeat-static-cling.html)
+says it excellently. Check it out.
+
+## My mock object needs to do complex stuff. It's a lot of pain to specify the actions. Google Mock sucks! ##
+
+I know it's not a question, but you get an answer for free any way. :-)
+
+With Google Mock, you can create mocks in C++ easily. And people might be
+tempted to use them everywhere. Sometimes they work great, and
+sometimes you may find them, well, a pain to use. So, what's wrong in
+the latter case?
+
+When you write a test without using mocks, you exercise the code and
+assert that it returns the correct value or that the system is in an
+expected state. This is sometimes called "state-based testing".
+
+Mocks are great for what some call "interaction-based" testing:
+instead of checking the system state at the very end, mock objects
+verify that they are invoked the right way and report an error as soon
+as it arises, giving you a handle on the precise context in which the
+error was triggered. This is often more effective and economical to
+do than state-based testing.
+
+If you are doing state-based testing and using a test double just to
+simulate the real object, you are probably better off using a fake.
+Using a mock in this case causes pain, as it's not a strong point for
+mocks to perform complex actions. If you experience this and think
+that mocks suck, you are just not using the right tool for your
+problem. Or, you might be trying to solve the wrong problem. :-)
+
+## I got a warning "Uninteresting function call encountered - default action taken.." Should I panic? ##
+
+By all means, NO! It's just an FYI.
+
+What it means is that you have a mock function, you haven't set any
+expectations on it (by Google Mock's rule this means that you are not
+interested in calls to this function and therefore it can be called
+any number of times), and it is called. That's OK - you didn't say
+it's not OK to call the function!
+
+What if you actually meant to disallow this function to be called, but
+forgot to write `EXPECT_CALL(foo, Bar()).Times(0)`? While
+one can argue that it's the user's fault, Google Mock tries to be nice and
+prints you a note.
+
+So, when you see the message and believe that there shouldn't be any
+uninteresting calls, you should investigate what's going on. To make
+your life easier, Google Mock prints the function name and arguments
+when an uninteresting call is encountered.
+
+## I want to define a custom action. Should I use Invoke() or implement the action interface? ##
+
+Either way is fine - you want to choose the one that's more convenient
+for your circumstance.
+
+Usually, if your action is for a particular function type, defining it
+using `Invoke()` should be easier; if your action can be used in
+functions of different types (e.g. if you are defining
+`Return(value)`), `MakePolymorphicAction()` is
+easiest. Sometimes you want precise control on what types of
+functions the action can be used in, and implementing
+`ActionInterface` is the way to go here. See the implementation of
+`Return()` in `include/gmock/gmock-actions.h` for an example.
+
+## I'm using the set-argument-pointee action, and the compiler complains about "conflicting return type specified". What does it mean? ##
+
+You got this error as Google Mock has no idea what value it should return
+when the mock method is called. `SetArgPointee()` says what the
+side effect is, but doesn't say what the return value should be. You
+need `DoAll()` to chain a `SetArgPointee()` with a `Return()`.
+
+See this [recipe](CookBook.md#mocking_side_effects) for more details and an example.

+As any non-trivial software system, Google Mock has some known limitations and problems. We are working on improving it, and welcome your help! The follow is a list of issues we know about.
+
+
+
+## README contains outdated information on Google Mock's compatibility with other testing frameworks ##
+
+The `README` file in release 1.1.0 still says that Google Mock only works with Google Test. Actually, you can configure Google Mock to work with any testing framework you choose.
+
+## Tests failing on machines using Power PC CPUs (e.g. some Macs) ##
+
+`gmock_output_test` and `gmock-printers_test` are known to fail with Power PC CPUs. This is due to portability issues with these tests, and is not an indication of problems in Google Mock itself. You can safely ignore them.
+
+## Failed to resolve libgtest.so.0 in tests when built against installed Google Test ##
+
+This only applies if you manually built and installed Google Test, and then built a Google Mock against it (either explicitly, or because gtest-config was in your path post-install). In this situation, Libtool has a known issue with certain systems' ldconfig setup:
+
+http://article.gmane.org/gmane.comp.sysutils.automake.general/9025
+
+This requires a manual run of "sudo ldconfig" after the "sudo make install" for Google Test before any binaries which link against it can be executed. This isn't a bug in our install, but we should at least have documented it or hacked a work-around into our install. We should have one of these solutions in our next release.

+// The ACTION* family of macros can be used in a namespace scope to
+// define custom actions easily. The syntax:
+//
+// ACTION(name) { statements; }
+//
+// will define an action with the given name that executes the
+// statements. The value returned by the statements will be used as
+// the return value of the action. Inside the statements, you can
+// refer to the K-th (0-based) argument of the mock function by
+// 'argK', and refer to its type by 'argK_type'. For example:
+//
+// ACTION(IncrementArg1) {
+// arg1_type temp = arg1;
+// return ++(*temp);
+// }
+//
+// allows you to write
+//
+// ...WillOnce(IncrementArg1());
+//
+// You can also refer to the entire argument tuple and its type by
+// 'args' and 'args_type', and refer to the mock function type and its
+// return type by 'function_type' and 'return_type'.
+//
+// Note that you don't need to specify the types of the mock function
+// arguments. However rest assured that your code is still type-safe:
+// you'll get a compiler error if *arg1 doesn't support the ++
+// operator, or if the type of ++(*arg1) isn't compatible with the
+// mock function's return type, for example.
+//
+// Sometimes you'll want to parameterize the action. For that you can use
+// another macro:
+//
+// ACTION_P(name, param_name) { statements; }
+//
+// For example:
+//
+// ACTION_P(Add, n) { return arg0 + n; }
+//
+// will allow you to write:
+//
+// ...WillOnce(Add(5));
+//
+// Note that you don't need to provide the type of the parameter
+// either. If you need to reference the type of a parameter named
+// 'foo', you can write 'foo_type'. For example, in the body of
+// ACTION_P(Add, n) above, you can write 'n_type' to refer to the type
+// of 'n'.
+//
+// We also provide ACTION_P2, ACTION_P3, ..., up to ACTION_P10 to support
+// multi-parameter actions.
+//
+// For the purpose of typing, you can view
+//
+// ACTION_Pk(Foo, p1, ..., pk) { ... }
+//
+// as shorthand for
+//
+// template <typename p1_type, ..., typename pk_type>
+// FooActionPk<p1_type, ..., pk_type> Foo(p1_type p1, ..., pk_type pk) { ... }
+//
+// In particular, you can provide the template type arguments
+// explicitly when invoking Foo(), as in Foo<long, bool>(5, false);
+// although usually you can rely on the compiler to infer the types
+// for you automatically. You can assign the result of expression
+// Foo(p1, ..., pk) to a variable of type FooActionPk<p1_type, ...,
+// pk_type>. This can be useful when composing actions.
+//
+// You can also overload actions with different numbers of parameters:
+//
+// ACTION_P(Plus, a) { ... }
+// ACTION_P2(Plus, a, b) { ... }
+//
+// While it's tempting to always use the ACTION* macros when defining
+// a new action, you should also consider implementing ActionInterface
+// or using MakePolymorphicAction() instead, especially if you need to
+// use the action a lot. While these approaches require more work,
+// they give you more control on the types of the mock function
+// arguments and the action parameters, which in general leads to
+// better compiler error messages that pay off in the long run. They
+// also allow overloading actions based on parameter types (as opposed
+// to just based on the number of parameters).
+//
+// CAVEAT:
+//
+// ACTION*() can only be used in a namespace scope. The reason is
+// that C++ doesn't yet allow function-local types to be used to
+// instantiate templates. The up-coming C++0x standard will fix this.
+// Once that's done, we'll consider supporting using ACTION*() inside
+// a function.

+// Sometimes you want to give an action explicit template parameters
+// that cannot be inferred from its value parameters. ACTION() and
+// ACTION_P*() don't support that. ACTION_TEMPLATE() remedies that
+// and can be viewed as an extension to ACTION() and ACTION_P*().
+//
+// The syntax:
+//
+// ACTION_TEMPLATE(ActionName,
+// HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
+// AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
+//
+// defines an action template that takes m explicit template
+// parameters and n value parameters. name_i is the name of the i-th
+// template parameter, and kind_i specifies whether it's a typename,
+// an integral constant, or a template. p_i is the name of the i-th
+// value parameter.
+//
+// Example:
+//
+// // DuplicateArg<k, T>(output) converts the k-th argument of the mock
+// // function to type T and copies it to *output.
+// ACTION_TEMPLATE(DuplicateArg,
+// HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
+// AND_1_VALUE_PARAMS(output)) {
+// *output = T(::testing::get<k>(args));
+// }
+// ...
+// int n;
+// EXPECT_CALL(mock, Foo(_, _))
+// .WillOnce(DuplicateArg<1, unsigned char>(&n));
+//
+// To create an instance of an action template, write:
+//
+// ActionName<t1, ..., t_m>(v1, ..., v_n)
+//
+// where the ts are the template arguments and the vs are the value
+// arguments. The value argument types are inferred by the compiler.
+// If you want to explicitly specify the value argument types, you can
+// provide additional template arguments:
+//
+// ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
+//
+// where u_i is the desired type of v_i.
+//
+// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
+// number of value parameters, but not on the number of template
+// parameters. Without the restriction, the meaning of the following
+// is unclear:
+//
+// OverloadedAction<int, bool>(x);
+//
+// Are we using a single-template-parameter action where 'bool' refers
+// to the type of x, or are we using a two-template-parameter action
+// where the compiler is asked to infer the type of x?
+//
+// Implementation notes:
+//
+// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
+// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
+// implementing ACTION_TEMPLATE. The main trick we use is to create
+// new macro invocations when expanding a macro. For example, we have
+//
+// #define ACTION_TEMPLATE(name, template_params, value_params)
+// ... GMOCK_INTERNAL_DECL_##template_params ...
+//
+// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
+// to expand to
+//
+// ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
+//
+// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
+// preprocessor will continue to expand it to
+//
+// ... typename T ...
+//
+// This technique conforms to the C++ standard and is portable. It
+// allows us to implement action templates using O(N) code, where N is
+// the maximum number of template/value parameters supported. Without
+// using it, we'd have to devote O(N^2) amount of code to implement all
+// combinations of m and n.

+// (0-based) argument, which must be a k-ary callable, of the mock
+// function, with arguments a1, a2, ..., a_k.
+//
+// Notes:
+//
+// 1. The arguments are passed by value by default. If you need to
+// pass an argument by reference, wrap it inside ByRef(). For
+// example,
+//
+// InvokeArgument<1>(5, string("Hello"), ByRef(foo))
+//
+// passes 5 and string("Hello") by value, and passes foo by
+// reference.
+//
+// 2. If the callable takes an argument by reference but ByRef() is
+// not used, it will receive the reference to a copy of the value,
+// instead of the original value. For example, when the 0-th
+// argument of the mock function takes a const string&, the action
+//
+// InvokeArgument<0>(string("Hello"))
+//
+// makes a copy of the temporary string("Hello") object and passes a
+// reference of the copy, instead of the original temporary object,
+// to the callable. This makes it easy for a user to define an
+// InvokeArgument action from temporary values and have it performed

+// will define an action with the given name that executes the
+// statements. The value returned by the statements will be used as
+// the return value of the action. Inside the statements, you can
+// refer to the K-th (0-based) argument of the mock function by
+// 'argK', and refer to its type by 'argK_type'. For example:
+//
+// ACTION(IncrementArg1) {
+// arg1_type temp = arg1;
+// return ++(*temp);
+// }
+//
+// allows you to write
+//
+// ...WillOnce(IncrementArg1());
+//
+// You can also refer to the entire argument tuple and its type by
+// 'args' and 'args_type', and refer to the mock function type and its
+// return type by 'function_type' and 'return_type'.
+//
+// Note that you don't need to specify the types of the mock function
+// arguments. However rest assured that your code is still type-safe:
+// you'll get a compiler error if *arg1 doesn't support the ++
+// operator, or if the type of ++(*arg1) isn't compatible with the
+// mock function's return type, for example.
+//
+// Sometimes you'll want to parameterize the action. For that you can use
+// another macro:
+//
+// ACTION_P(name, param_name) { statements; }
+//
+// For example:
+//
+// ACTION_P(Add, n) { return arg0 + n; }
+//
+// will allow you to write:
+//
+// ...WillOnce(Add(5));
+//
+// Note that you don't need to provide the type of the parameter
+// either. If you need to reference the type of a parameter named
+// 'foo', you can write 'foo_type'. For example, in the body of
+// ACTION_P(Add, n) above, you can write 'n_type' to refer to the type
+// of 'n'.
+//
+// We also provide ACTION_P2, ACTION_P3, ..., up to ACTION_P$n to support
+// multi-parameter actions.
+//
+// For the purpose of typing, you can view
+//
+// ACTION_Pk(Foo, p1, ..., pk) { ... }
+//
+// as shorthand for
+//
+// template <typename p1_type, ..., typename pk_type>
+// FooActionPk<p1_type, ..., pk_type> Foo(p1_type p1, ..., pk_type pk) { ... }
+//
+// In particular, you can provide the template type arguments
+// explicitly when invoking Foo(), as in Foo<long, bool>(5, false);
+// although usually you can rely on the compiler to infer the types
+// for you automatically. You can assign the result of expression
+// Foo(p1, ..., pk) to a variable of type FooActionPk<p1_type, ...,
+// pk_type>. This can be useful when composing actions.
+//
+// You can also overload actions with different numbers of parameters:
+//
+// ACTION_P(Plus, a) { ... }
+// ACTION_P2(Plus, a, b) { ... }
+//
+// While it's tempting to always use the ACTION* macros when defining
+// a new action, you should also consider implementing ActionInterface
+// or using MakePolymorphicAction() instead, especially if you need to
+// use the action a lot. While these approaches require more work,
+// they give you more control on the types of the mock function
+// arguments and the action parameters, which in general leads to
+// better compiler error messages that pay off in the long run. They
+// also allow overloading actions based on parameter types (as opposed
+// to just based on the number of parameters).
+//
+// CAVEAT:
+//
+// ACTION*() can only be used in a namespace scope. The reason is
+// that C++ doesn't yet allow function-local types to be used to
+// instantiate templates. The up-coming C++0x standard will fix this.
+// Once that's done, we'll consider supporting using ACTION*() inside
+// a function.

+// // DuplicateArg<k, T>(output) converts the k-th argument of the mock
+// // function to type T and copies it to *output.
+// ACTION_TEMPLATE(DuplicateArg,
+// HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
+// AND_1_VALUE_PARAMS(output)) {
+// *output = T(::testing::get<k>(args));
+// }
+// ...
+// int n;
+// EXPECT_CALL(mock, Foo(_, _))
+// .WillOnce(DuplicateArg<1, unsigned char>(&n));
+//
+// To create an instance of an action template, write:
+//
+// ActionName<t1, ..., t_m>(v1, ..., v_n)
+//
+// where the ts are the template arguments and the vs are the value
+// arguments. The value argument types are inferred by the compiler.
+// If you want to explicitly specify the value argument types, you can
+// provide additional template arguments:
+//
+// ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
+//
+// where u_i is the desired type of v_i.
+//
+// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
+// number of value parameters, but not on the number of template
+// parameters. Without the restriction, the meaning of the following
+// is unclear:
+//
+// OverloadedAction<int, bool>(x);
+//
+// Are we using a single-template-parameter action where 'bool' refers
+// to the type of x, or are we using a two-template-parameter action
+// where the compiler is asked to infer the type of x?
+//
+// Implementation notes:
+//
+// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
+// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
+// implementing ACTION_TEMPLATE. The main trick we use is to create
+// new macro invocations when expanding a macro. For example, we have
+//
+// #define ACTION_TEMPLATE(name, template_params, value_params)
+// ... GMOCK_INTERNAL_DECL_##template_params ...
+//
+// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
+// to expand to
+//
+// ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
+//
+// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
+// preprocessor will continue to expand it to
+//
+// ... typename T ...
+//
+// This technique conforms to the C++ standard and is portable. It
+// allows us to implement action templates using O(N) code, where N is
+// the maximum number of template/value parameters supported. Without
+// using it, we'd have to devote O(N^2) amount of code to implement all
+// combinations of m and n.

+// A MockFunction<F> class has one mock method whose type is F. It is
+// useful when you just want your test code to emit some messages and
+// have Google Mock verify the right messages are sent (and perhaps at
+// the right times). For example, if you are exercising code:
+//
+// Foo(1);
+// Foo(2);
+// Foo(3);
+//
+// and want to verify that Foo(1) and Foo(3) both invoke
+// mock.Bar("a"), but Foo(2) doesn't invoke anything, you can write:
+//
+// TEST(FooTest, InvokesBarCorrectly) {
+// MyMock mock;
+// MockFunction<void(string check_point_name)> check;
+// {
+// InSequence s;
+//
+// EXPECT_CALL(mock, Bar("a"));
+// EXPECT_CALL(check, Call("1"));
+// EXPECT_CALL(check, Call("2"));
+// EXPECT_CALL(mock, Bar("a"));
+// }
+// Foo(1);
+// check.Call("1");
+// Foo(2);
+// check.Call("2");
+// Foo(3);
+// }
+//
+// The expectation spec says that the first Bar("a") must happen
+// before check point "1", the second Bar("a") must happen after check
+// point "2", and nothing should happen between the two check
+// points. The explicit check points make it easy to tell which
+// Bar("a") is called by which call to Foo().
+//
+// MockFunction<F> can also be used to exercise code that accepts
+// std::function<F> callbacks. To do so, use AsStdFunction() method
+// to create std::function proxy forwarding to original object's Call.
+// Example:
+//
+// TEST(FooTest, RunsCallbackWithBarArgument) {
+// MockFunction<int(string)> callback;
+// EXPECT_CALL(callback, Call("bar")).WillOnce(Return(1));
+// Foo(callback.AsStdFunction());
+// }

+// A MockFunction<F> class has one mock method whose type is F. It is
+// useful when you just want your test code to emit some messages and
+// have Google Mock verify the right messages are sent (and perhaps at
+// the right times). For example, if you are exercising code:
+//
+// Foo(1);
+// Foo(2);
+// Foo(3);
+//
+// and want to verify that Foo(1) and Foo(3) both invoke
+// mock.Bar("a"), but Foo(2) doesn't invoke anything, you can write:
+//
+// TEST(FooTest, InvokesBarCorrectly) {
+// MyMock mock;
+// MockFunction<void(string check_point_name)> check;
+// {
+// InSequence s;
+//
+// EXPECT_CALL(mock, Bar("a"));
+// EXPECT_CALL(check, Call("1"));
+// EXPECT_CALL(check, Call("2"));
+// EXPECT_CALL(mock, Bar("a"));
+// }
+// Foo(1);
+// check.Call("1");
+// Foo(2);
+// check.Call("2");
+// Foo(3);
+// }
+//
+// The expectation spec says that the first Bar("a") must happen
+// before check point "1", the second Bar("a") must happen after check
+// point "2", and nothing should happen between the two check
+// points. The explicit check points make it easy to tell which
+// Bar("a") is called by which call to Foo().
+//
+// MockFunction<F> can also be used to exercise code that accepts
+// std::function<F> callbacks. To do so, use AsStdFunction() method
+// to create std::function proxy forwarding to original object's Call.
+// Example:
+//
+// TEST(FooTest, RunsCallbackWithBarArgument) {
+// MockFunction<int(string)> callback;
+// EXPECT_CALL(callback, Call("bar")).WillOnce(Return(1));
+// Foo(callback.AsStdFunction());

+} // namespace testing
+
+
+// The MATCHER* family of macros can be used in a namespace scope to
+// define custom matchers easily.
+//
+// Basic Usage
+// ===========
+//
+// The syntax
+//
+// MATCHER(name, description_string) { statements; }
+//
+// defines a matcher with the given name that executes the statements,
+// which must return a bool to indicate if the match succeeds. Inside
+// the statements, you can refer to the value being matched by 'arg',
+// and refer to its type by 'arg_type'.
+//
+// The description string documents what the matcher does, and is used
+// to generate the failure message when the match fails. Since a
+// MATCHER() is usually defined in a header file shared by multiple
+// C++ source files, we require the description to be a C-string
+// literal to avoid possible side effects. It can be empty, in which
+// case we'll use the sequence of words in the matcher name as the
+// description.
+//
+// For example:
+//
+// MATCHER(IsEven, "") { return (arg % 2) == 0; }
+//
+// allows you to write
+//
+// // Expects mock_foo.Bar(n) to be called where n is even.
+// EXPECT_CALL(mock_foo, Bar(IsEven()));
+//
+// or,
+//
+// // Verifies that the value of some_expression is even.
+// EXPECT_THAT(some_expression, IsEven());
+//
+// If the above assertion fails, it will print something like:
+//
+// Value of: some_expression
+// Expected: is even
+// Actual: 7
+//
+// where the description "is even" is automatically calculated from the
+// matcher name IsEven.
+//
+// Argument Type
+// =============
+//
+// Note that the type of the value being matched (arg_type) is
+// determined by the context in which you use the matcher and is
+// supplied to you by the compiler, so you don't need to worry about
+// declaring it (nor can you). This allows the matcher to be
+// polymorphic. For example, IsEven() can be used to match any type
+// where the value of "(arg % 2) == 0" can be implicitly converted to
+// a bool. In the "Bar(IsEven())" example above, if method Bar()
+// takes an int, 'arg_type' will be int; if it takes an unsigned long,
+// 'arg_type' will be unsigned long; and so on.
+//
+// Parameterizing Matchers
+// =======================
+//
+// Sometimes you'll want to parameterize the matcher. For that you
+// can use another macro:
+//
+// MATCHER_P(name, param_name, description_string) { statements; }
+//
+// For example:
+//
+// MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
+//
+// will allow you to write:
+//
+// EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
+//
+// which may lead to this message (assuming n is 10):
+//
+// Value of: Blah("a")
+// Expected: has absolute value 10
+// Actual: -9
+//
+// Note that both the matcher description and its parameter are
+// printed, making the message human-friendly.
+//
+// In the matcher definition body, you can write 'foo_type' to
+// reference the type of a parameter named 'foo'. For example, in the
+// body of MATCHER_P(HasAbsoluteValue, value) above, you can write
+// 'value_type' to refer to the type of 'value'.
+//
+// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P10 to
+// support multi-parameter matchers.
+//
+// Describing Parameterized Matchers
+// =================================
+//
+// The last argument to MATCHER*() is a string-typed expression. The
+// expression can reference all of the matcher's parameters and a
+// special bool-typed variable named 'negation'. When 'negation' is
+// false, the expression should evaluate to the matcher's description;
+// otherwise it should evaluate to the description of the negation of
+// the matcher. For example,
+//
+// using testing::PrintToString;
+//
+// MATCHER_P2(InClosedRange, low, hi,
+// std::string(negation ? "is not" : "is") + " in range [" +
+// PrintToString(low) + ", " + PrintToString(hi) + "]") {
+// return low <= arg && arg <= hi;
+// }
+// ...
+// EXPECT_THAT(3, InClosedRange(4, 6));
+// EXPECT_THAT(3, Not(InClosedRange(2, 4)));
+//
+// would generate two failures that contain the text:
+//
+// Expected: is in range [4, 6]
+// ...
+// Expected: is not in range [2, 4]
+//
+// If you specify "" as the description, the failure message will
+// contain the sequence of words in the matcher name followed by the
+// parameter values printed as a tuple. For example,
+//
+// MATCHER_P2(InClosedRange, low, hi, "") { ... }
+// ...
+// EXPECT_THAT(3, InClosedRange(4, 6));
+// EXPECT_THAT(3, Not(InClosedRange(2, 4)));
+//
+// would generate two failures that contain the text:
+//
+// Expected: in closed range (4, 6)
+// ...
+// Expected: not (in closed range (2, 4))
+//
+// Types of Matcher Parameters
+// ===========================
+//
+// For the purpose of typing, you can view
+//
+// MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
+//
+// as shorthand for
+//
+// template <typename p1_type, ..., typename pk_type>
+// FooMatcherPk<p1_type, ..., pk_type>
+// Foo(p1_type p1, ..., pk_type pk) { ... }
+//
+// When you write Foo(v1, ..., vk), the compiler infers the types of
+// the parameters v1, ..., and vk for you. If you are not happy with
+// the result of the type inference, you can specify the types by
+// explicitly instantiating the template, as in Foo<long, bool>(5,
+// false). As said earlier, you don't get to (or need to) specify
+// 'arg_type' as that's determined by the context in which the matcher
+// is used. You can assign the result of expression Foo(p1, ..., pk)
+// to a variable of type FooMatcherPk<p1_type, ..., pk_type>. This
+// can be useful when composing matchers.
+//
+// While you can instantiate a matcher template with reference types,
+// passing the parameters by pointer usually makes your code more
+// readable. If, however, you still want to pass a parameter by
+// reference, be aware that in the failure message generated by the
+// matcher you will see the value of the referenced object but not its
+// address.
+//
+// Explaining Match Results
+// ========================
+//
+// Sometimes the matcher description alone isn't enough to explain why
+// the match has failed or succeeded. For example, when expecting a
+// long string, it can be very helpful to also print the diff between
+// the expected string and the actual one. To achieve that, you can
+// optionally stream additional information to a special variable
+// named result_listener, whose type is a pointer to class
+// MatchResultListener:
+//
+// MATCHER_P(EqualsLongString, str, "") {
+// if (arg == str) return true;
+//
+// *result_listener << "the difference: "
+/// << DiffStrings(str, arg);
+// return false;
+// }
+//
+// Overloading Matchers
+// ====================
+//
+// You can overload matchers with different numbers of parameters:
+//
+// MATCHER_P(Blah, a, description_string1) { ... }
+// MATCHER_P2(Blah, a, b, description_string2) { ... }
+//
+// Caveats
+// =======
+//
+// When defining a new matcher, you should also consider implementing
+// MatcherInterface or using MakePolymorphicMatcher(). These
+// approaches require more work than the MATCHER* macros, but also
+// give you more control on the types of the value being matched and
+// the matcher parameters, which may leads to better compiler error
+// messages when the matcher is used wrong. They also allow
+// overloading matchers based on parameter types (as opposed to just
+// based on the number of parameters).
+//
+// MATCHER*() can only be used in a namespace scope. The reason is
+// that C++ doesn't yet allow function-local types to be used to
+// instantiate templates. The up-coming C++0x standard will fix this.
+// Once that's done, we'll consider supporting using MATCHER*() inside
+// a function.
+//

+// The MATCHER* family of macros can be used in a namespace scope to
+// define custom matchers easily.
+//
+// Basic Usage
+// ===========
+//
+// The syntax
+//
+// MATCHER(name, description_string) { statements; }
+//
+// defines a matcher with the given name that executes the statements,
+// which must return a bool to indicate if the match succeeds. Inside
+// the statements, you can refer to the value being matched by 'arg',
+// and refer to its type by 'arg_type'.
+//
+// The description string documents what the matcher does, and is used
+// to generate the failure message when the match fails. Since a
+// MATCHER() is usually defined in a header file shared by multiple
+// C++ source files, we require the description to be a C-string
+// literal to avoid possible side effects. It can be empty, in which
+// case we'll use the sequence of words in the matcher name as the
+// description.
+//
+// For example:
+//
+// MATCHER(IsEven, "") { return (arg % 2) == 0; }
+//
+// allows you to write
+//
+// // Expects mock_foo.Bar(n) to be called where n is even.
+// EXPECT_CALL(mock_foo, Bar(IsEven()));
+//
+// or,
+//
+// // Verifies that the value of some_expression is even.
+// EXPECT_THAT(some_expression, IsEven());
+//
+// If the above assertion fails, it will print something like:
+//
+// Value of: some_expression
+// Expected: is even
+// Actual: 7
+//
+// where the description "is even" is automatically calculated from the
+// matcher name IsEven.
+//
+// Argument Type
+// =============
+//
+// Note that the type of the value being matched (arg_type) is
+// determined by the context in which you use the matcher and is
+// supplied to you by the compiler, so you don't need to worry about
+// declaring it (nor can you). This allows the matcher to be
+// polymorphic. For example, IsEven() can be used to match any type
+// where the value of "(arg % 2) == 0" can be implicitly converted to
+// a bool. In the "Bar(IsEven())" example above, if method Bar()
+// takes an int, 'arg_type' will be int; if it takes an unsigned long,
+// 'arg_type' will be unsigned long; and so on.
+//
+// Parameterizing Matchers
+// =======================
+//
+// Sometimes you'll want to parameterize the matcher. For that you
+// can use another macro:
+//
+// MATCHER_P(name, param_name, description_string) { statements; }
+//
+// For example:
+//
+// MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
+//
+// will allow you to write:
+//
+// EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
+//
+// which may lead to this message (assuming n is 10):
+//
+// Value of: Blah("a")
+// Expected: has absolute value 10
+// Actual: -9
+//
+// Note that both the matcher description and its parameter are
+// printed, making the message human-friendly.
+//
+// In the matcher definition body, you can write 'foo_type' to
+// reference the type of a parameter named 'foo'. For example, in the
+// body of MATCHER_P(HasAbsoluteValue, value) above, you can write
+// 'value_type' to refer to the type of 'value'.
+//
+// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P$n to
+// support multi-parameter matchers.
+//
+// Describing Parameterized Matchers
+// =================================
+//
+// The last argument to MATCHER*() is a string-typed expression. The
+// expression can reference all of the matcher's parameters and a
+// special bool-typed variable named 'negation'. When 'negation' is
+// false, the expression should evaluate to the matcher's description;
+// otherwise it should evaluate to the description of the negation of
+// the matcher. For example,
+//
+// using testing::PrintToString;
+//
+// MATCHER_P2(InClosedRange, low, hi,
+// std::string(negation ? "is not" : "is") + " in range [" +
+// PrintToString(low) + ", " + PrintToString(hi) + "]") {
+// return low <= arg && arg <= hi;
+// }
+// ...
+// EXPECT_THAT(3, InClosedRange(4, 6));
+// EXPECT_THAT(3, Not(InClosedRange(2, 4)));
+//
+// would generate two failures that contain the text:
+//
+// Expected: is in range [4, 6]
+// ...
+// Expected: is not in range [2, 4]
+//
+// If you specify "" as the description, the failure message will
+// contain the sequence of words in the matcher name followed by the
+// parameter values printed as a tuple. For example,
+//
+// MATCHER_P2(InClosedRange, low, hi, "") { ... }
+// ...
+// EXPECT_THAT(3, InClosedRange(4, 6));
+// EXPECT_THAT(3, Not(InClosedRange(2, 4)));
+//
+// would generate two failures that contain the text:
+//
+// Expected: in closed range (4, 6)
+// ...
+// Expected: not (in closed range (2, 4))
+//
+// Types of Matcher Parameters
+// ===========================
+//
+// For the purpose of typing, you can view
+//
+// MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
+//
+// as shorthand for
+//
+// template <typename p1_type, ..., typename pk_type>
+// FooMatcherPk<p1_type, ..., pk_type>
+// Foo(p1_type p1, ..., pk_type pk) { ... }
+//
+// When you write Foo(v1, ..., vk), the compiler infers the types of
+// the parameters v1, ..., and vk for you. If you are not happy with
+// the result of the type inference, you can specify the types by
+// explicitly instantiating the template, as in Foo<long, bool>(5,
+// false). As said earlier, you don't get to (or need to) specify
+// 'arg_type' as that's determined by the context in which the matcher
+// is used. You can assign the result of expression Foo(p1, ..., pk)
+// to a variable of type FooMatcherPk<p1_type, ..., pk_type>. This
+// can be useful when composing matchers.
+//
+// While you can instantiate a matcher template with reference types,
+// passing the parameters by pointer usually makes your code more
+// readable. If, however, you still want to pass a parameter by
+// reference, be aware that in the failure message generated by the
+// matcher you will see the value of the referenced object but not its
+// address.
+//
+// Explaining Match Results
+// ========================
+//
+// Sometimes the matcher description alone isn't enough to explain why
+// the match has failed or succeeded. For example, when expecting a
+// long string, it can be very helpful to also print the diff between
+// the expected string and the actual one. To achieve that, you can
+// optionally stream additional information to a special variable
+// named result_listener, whose type is a pointer to class
+// MatchResultListener:
+//
+// MATCHER_P(EqualsLongString, str, "") {
+// if (arg == str) return true;
+//
+// *result_listener << "the difference: "
+/// << DiffStrings(str, arg);
+// return false;
+// }
+//
+// Overloading Matchers
+// ====================
+//
+// You can overload matchers with different numbers of parameters:
+//
+// MATCHER_P(Blah, a, description_string1) { ... }
+// MATCHER_P2(Blah, a, b, description_string2) { ... }
+//
+// Caveats
+// =======
+//
+// When defining a new matcher, you should also consider implementing
+// MatcherInterface or using MakePolymorphicMatcher(). These
+// approaches require more work than the MATCHER* macros, but also
+// give you more control on the types of the value being matched and
+// the matcher parameters, which may leads to better compiler error
+// messages when the matcher is used wrong. They also allow
+// overloading matchers based on parameter types (as opposed to just
+// based on the number of parameters).
+//
+// MATCHER*() can only be used in a namespace scope. The reason is
+// that C++ doesn't yet allow function-local types to be used to
+// instantiate templates. The up-coming C++0x standard will fix this.
+// Once that's done, we'll consider supporting using MATCHER*() inside
+// a function.
+//

+// Implements class templates NiceMock, NaggyMock, and StrictMock.
+//
+// Given a mock class MockFoo that is created using Google Mock,
+// NiceMock<MockFoo> is a subclass of MockFoo that allows
+// uninteresting calls (i.e. calls to mock methods that have no
+// EXPECT_CALL specs), NaggyMock<MockFoo> is a subclass of MockFoo
+// that prints a warning when an uninteresting call occurs, and
+// StrictMock<MockFoo> is a subclass of MockFoo that treats all
+// uninteresting calls as errors.
+//
+// Currently a mock is naggy by default, so MockFoo and
+// NaggyMock<MockFoo> behave like the same. However, we will soon
+// switch the default behavior of mocks to be nice, as that in general
+// leads to more maintainable tests. When that happens, MockFoo will
+// stop behaving like NaggyMock<MockFoo> and start behaving like
+// NiceMock<MockFoo>.
+//
+// NiceMock, NaggyMock, and StrictMock "inherit" the constructors of
+// their respective base class. Therefore you can write
+// NiceMock<MockFoo>(5, "a") to construct a nice mock where MockFoo
+// has a constructor that accepts (int, const char*), for example.
+//
+// A known limitation is that NiceMock<MockFoo>, NaggyMock<MockFoo>,
+// and StrictMock<MockFoo> only works for mock methods defined using
+// the MOCK_METHOD* family of macros DIRECTLY in the MockFoo class.
+// If a mock method is defined in a base class of MockFoo, the "nice"
+// or "strict" modifier may not affect it, depending on the compiler.
+// In particular, nesting NiceMock, NaggyMock, and StrictMock is NOT
+// supported.

+// Implements class templates NiceMock, NaggyMock, and StrictMock.
+//
+// Given a mock class MockFoo that is created using Google Mock,
+// NiceMock<MockFoo> is a subclass of MockFoo that allows
+// uninteresting calls (i.e. calls to mock methods that have no
+// EXPECT_CALL specs), NaggyMock<MockFoo> is a subclass of MockFoo
+// that prints a warning when an uninteresting call occurs, and
+// StrictMock<MockFoo> is a subclass of MockFoo that treats all
+// uninteresting calls as errors.
+//
+// Currently a mock is naggy by default, so MockFoo and
+// NaggyMock<MockFoo> behave like the same. However, we will soon
+// switch the default behavior of mocks to be nice, as that in general
+// leads to more maintainable tests. When that happens, MockFoo will
+// stop behaving like NaggyMock<MockFoo> and start behaving like
+// NiceMock<MockFoo>.
+//
+// NiceMock, NaggyMock, and StrictMock "inherit" the constructors of
+// their respective base class. Therefore you can write
+// NiceMock<MockFoo>(5, "a") to construct a nice mock where MockFoo
+// has a constructor that accepts (int, const char*), for example.
+//
+// A known limitation is that NiceMock<MockFoo>, NaggyMock<MockFoo>,
+// and StrictMock<MockFoo> only works for mock methods defined using
+// the MOCK_METHOD* family of macros DIRECTLY in the MockFoo class.
+// If a mock method is defined in a base class of MockFoo, the "nice"
+// or "strict" modifier may not affect it, depending on the compiler.
+// In particular, nesting NiceMock, NaggyMock, and StrictMock is NOT
+// supported.

+// Implementation for ON_CALL and EXPECT_CALL macros. A separate macro is
+// required to avoid compile errors when the name of the method used in call is
+// a result of macro expansion. See CompilesWithMethodNameExpandedFromMacro
+// tests in internal/gmock-spec-builders_test.cc for more details.
+//
+// This macro supports statements both with and without parameter matchers. If
+// the parameter list is omitted, gMock will accept any parameters, which allows
+// tests to be written that don't need to encode the number of method
+// parameter. This technique may only be used for non-overloaded methods.
+//
+// // These are the same:
+// ON_CALL(mock, NoArgsMethod()).WillByDefault(…);
+// ON_CALL(mock, NoArgsMethod).WillByDefault(…);
+//
+// // As are these:
+// ON_CALL(mock, TwoArgsMethod(_, _)).WillByDefault(…);
+// ON_CALL(mock, TwoArgsMethod).WillByDefault(…);
+//
+// // Can also specify args if you want, of course:
+// ON_CALL(mock, TwoArgsMethod(_, 45)).WillByDefault(…);
+//
+// // Overloads work as long as you specify parameters:
+// ON_CALL(mock, OverloadedMethod(_)).WillByDefault(…);
+// ON_CALL(mock, OverloadedMethod(_, _)).WillByDefault(…);
+//
+// // Oops! Which overload did you want?
+// ON_CALL(mock, OverloadedMethod).WillByDefault(…);
+// => ERROR: call to member function 'gmock_OverloadedMethod' is ambiguous
+//
+// How this works: The mock class uses two overloads of the gmock_Method
+// expectation setter method plus an operator() overload on the MockSpec object.
+// In the matcher list form, the macro expands to:
+//
+// // This statement:
+// ON_CALL(mock, TwoArgsMethod(_, 45))…
+//
+// // …expands to:
+// mock.gmock_TwoArgsMethod(_, 45)(WithoutMatchers(), nullptr)…
+// |-------------v---------------||------------v-------------|
+// invokes first overload swallowed by operator()
+//
+// // …which is essentially:
+// mock.gmock_TwoArgsMethod(_, 45)…
+//
+// Whereas the form without a matcher list:
+//
+// // This statement:
+// ON_CALL(mock, TwoArgsMethod)…
+//
+// // …expands to:
+// mock.gmock_TwoArgsMethod(WithoutMatchers(), nullptr)…
+// |-----------------------v--------------------------|
+// invokes second overload
+//
+// // …which is essentially:
+// mock.gmock_TwoArgsMethod(_, _)…
+//
+// The WithoutMatchers() argument is used to disambiguate overloads and to
+// block the caller from accidentally invoking the second overload directly. The
+// second argument is an internal type derived from the method signature. The
+// failure to disambiguate two overloads of this method in the ON_CALL statement
+// is how we block callers from setting expectations on overloaded methods.

+"""fuse_gmock_files.py v0.1.0
+Fuses Google Mock and Google Test source code into two .h files and a .cc file.
+
+SYNOPSIS
+ fuse_gmock_files.py [GMOCK_ROOT_DIR] OUTPUT_DIR
+
+ Scans GMOCK_ROOT_DIR for Google Mock and Google Test source
+ code, assuming Google Test is in the GMOCK_ROOT_DIR/../googletest
+ directory, and generates three files:
+ OUTPUT_DIR/gtest/gtest.h, OUTPUT_DIR/gmock/gmock.h, and
+ OUTPUT_DIR/gmock-gtest-all.cc. Then you can build your tests
+ by adding OUTPUT_DIR to the include search path and linking
+ with OUTPUT_DIR/gmock-gtest-all.cc. These three files contain
+ everything you need to use Google Mock. Hence you can
+ "install" Google Mock by copying them to wherever you want.
+
+ GMOCK_ROOT_DIR can be omitted and defaults to the parent
+ directory of the directory holding this script.
+
+EXAMPLES
+ ./fuse_gmock_files.py fused_gmock
+ ./fuse_gmock_files.py path/to/unpacked/gmock fused_gmock
+
+This tool is experimental. In particular, it assumes that there is no
+conditional inclusion of Google Mock or Google Test headers. Please
+report any problems to googlemock@googlegroups.com. You can read
+https://github.com/google/googletest/blob/master/googlemock/docs/CookBook.md for more
+information.

+
+The Google Mock class generator is an application that is part of cppclean.
+For more information about cppclean, see the README.cppclean file or
+visit http://code.google.com/p/cppclean/
+
+cppclean requires Python 2.3.5 or later. If you don't have Python installed
+on your system, you will also need to install it. You can download Python
+from: http://www.python.org/download/releases/
+
+To use the Google Mock class generator, you need to call it
+on the command line passing the header file and class for which you want
+to generate a Google Mock class.
+
+Make sure to install the scripts somewhere in your path. Then you can
+run the program.
+
+ gmock_gen.py header-file.h [ClassName]...
+
+If no ClassNames are specified, all classes in the file are emitted.
+
+To change the indentation from the default of 2, set INDENT in
+the environment. For example to use an indent of 4 spaces:
+
+INDENT=4 gmock_gen.py header-file.h ClassName
+
+This version was made from SVN revision 281 in the cppclean repository.
+
+Known Limitations
+-----------------
+Not all code will be generated properly. For example, when mocking templated
+classes, the template information is lost. You will need to add the template
+information manually.
+
+Not all permutations of using multiple pointers/references will be rendered
+properly. These will also have to be fixed manually.

+Goal:
+-----
+ CppClean attempts to find problems in C++ source that slow development
+ in large code bases, for example various forms of unused code.
+ Unused code can be unused functions, methods, data members, types, etc
+ to unnecessary #include directives. Unnecessary #includes can cause
+ considerable extra compiles increasing the edit-compile-run cycle.
+
+ The project home page is: http://code.google.com/p/cppclean/
+
+
+Features:
+---------
+ * Find and print C++ language constructs: classes, methods, functions, etc.
+ * Find classes with virtual methods, no virtual destructor, and no bases
+ * Find global/static data that are potential problems when using threads
+ * Unnecessary forward class declarations
+ * Unnecessary function declarations
+ * Undeclared function definitions
+ * (planned) Find unnecessary header files #included
+ - No direct reference to anything in the header
+ - Header is unnecessary if classes were forward declared instead
+ * (planned) Source files that reference headers not directly #included,
+ ie, files that rely on a transitive #include from another header
+ * (planned) Unused members (private, protected, & public) methods and data
+ * (planned) Store AST in a SQL database so relationships can be queried
+
+AST is Abstract Syntax Tree, a representation of parsed source code.
+http://en.wikipedia.org/wiki/Abstract_syntax_tree
+
+
+System Requirements:
+--------------------
+ * Python 2.4 or later (2.3 probably works too)
+ * Works on Windows (untested), Mac OS X, and Unix
+
+
+How to Run:
+-----------
+ For all examples, it is assumed that cppclean resides in a directory called
+ /cppclean.
+
+ To print warnings for classes with virtual methods, no virtual destructor and
+ no base classes:
+
+ /cppclean/run.sh nonvirtual_dtors.py file1.h file2.h file3.cc ...
+
+ To print all the functions defined in header file(s):
+
+ /cppclean/run.sh functions.py file1.h file2.h ...
+
+ All the commands take multiple files on the command line. Other programs
+ include: find_warnings, headers, methods, and types. Some other programs
+ are available, but used primarily for debugging.
+
+ run.sh is a simple wrapper that sets PYTHONPATH to /cppclean and then
+ runs the program in /cppclean/cpp/PROGRAM.py. There is currently
+ no equivalent for Windows. Contributions for a run.bat file
+ would be greatly appreciated.
+
+
+How to Configure:
+-----------------
+ You can add a siteheaders.py file in /cppclean/cpp to configure where
+ to look for other headers (typically -I options passed to a compiler).
+ Currently two values are supported: _TRANSITIVE and GetIncludeDirs.
+ _TRANSITIVE should be set to a boolean value (True or False) indicating
+ whether to transitively process all header files. The default is False.
+
+ GetIncludeDirs is a function that takes a single argument and returns
+ a sequence of directories to include. This can be a generator or
+ return a static list.
+
+ def GetIncludeDirs(filename):
+ return ['/some/path/with/other/headers']
+
+ # Here is a more complicated example.
+ def GetIncludeDirs(filename):
+ yield '/path1'
+ yield os.path.join('/path2', os.path.dirname(filename))
+ yield '/path3'
+
+
+How to Test:
+------------
+ For all examples, it is assumed that cppclean resides in a directory called
+ /cppclean. The tests require
+
+ cd /cppclean
+ make test
+ # To generate expected results after a change:
+ make expected
+
+
+Current Status:
+---------------
+ The parser works pretty well for header files, parsing about 99% of Google's
+ header files. Anything which inspects structure of C++ source files should
+ work reasonably well. Function bodies are not transformed to an AST,
+ but left as tokens. Much work is still needed on finding unused header files
+ and storing an AST in a database.
+
+
+Non-goals:
+----------
+ * Parsing all valid C++ source
+ * Handling invalid C++ source gracefully
+ * Compiling to machine code (or anything beyond an AST)
+

+
+The `gmock-config' script provides access to the necessary compile and linking
+flags to connect with Google C++ Mocking Framework, both in a build prior to
+installation, and on the system proper after installation. The installation
+overrides may be issued in combination with any other queries, but will only
+affect installation queries if called on a built but not installed gmock. The
+installation queries may not be issued with any other types of queries, and
+only one installation query may be made at a time. The version queries and
+compiler flag queries may be combined as desired but not mixed. Different
+version queries are always combined with logical "and" semantics, and only the
+last of any particular query is used while all previous ones ignored. All
+versions must be specified as a sequence of numbers separated by periods.
+Compiler flag queries output the union of the sets of flags when combined.
+
+ Examples:
+ gmock-config --min-version=1.0 || echo "Insufficient Google Mock version."
+
+ g++ $(gmock-config --cppflags --cxxflags) -o foo.o -c foo.cpp
+ g++ $(gmock-config --ldflags --libs) -o foo foo.o
+
+ # When using a built but not installed Google Mock:
+ g++ $(../../my_gmock_build/scripts/gmock-config ...) ...
+
+ # When using an installed Google Mock, but with installation overrides:
+ export GMOCK_PREFIX="/opt"
+ g++ $(gmock-config --libdir="/opt/lib64" ...) ...

+ Installation Overrides:

+
+ Installation Queries:
+ --prefix installation prefix
+ --exec-prefix executable installation prefix
+ --libdir library installation directory
+ --includedir header file installation directory
+ --version the version of the Google Mock installation
+
+ Version Queries:
+ --min-version=VERSION return 0 if the version is at least VERSION

+ --cxxflags compile flags appropriate for C++ programs
+ --ldflags linker flags
+ --libs libraries for linking

+// FindMaxBipartiteMatching and its helper class.
+//
+// Uses the well-known Ford-Fulkerson max flow method to find a maximum
+// bipartite matching. Flow is considered to be from left to right.
+// There is an implicit source node that is connected to all of the left
+// nodes, and an implicit sink node that is connected to all of the
+// right nodes. All edges have unit capacity.
+//
+// Neither the flow graph nor the residual flow graph are represented
+// explicitly. Instead, they are implied by the information in 'graph' and
+// a vector<int> called 'left_' whose elements are initialized to the
+// value kUnused. This represents the initial state of the algorithm,
+// where the flow graph is empty, and the residual flow graph has the
+// following edges:
+// - An edge from source to each left_ node
+// - An edge from each right_ node to sink
+// - An edge from each left_ node to each right_ node, if the
+// corresponding edge exists in 'graph'.
+//
+// When the TryAugment() method adds a flow, it sets left_[l] = r for some
+// nodes l and r. This induces the following changes:
+// - The edges (source, l), (l, r), and (r, sink) are added to the
+// flow graph.
+// - The same three edges are removed from the residual flow graph.
+// - The reverse edges (l, source), (r, l), and (sink, r) are added
+// to the residual flow graph, which is a directional graph
+// representing unused flow capacity.
+//
+// When the method augments a flow (moving left_[l] from some r1 to some
+// other r2), this can be thought of as "undoing" the above steps with
+// respect to r1 and "redoing" them with respect to r2.
+//
+// It bears repeating that the flow graph and residual flow graph are
+// never represented explicitly, but can be derived by looking at the
+// information in 'graph' and in left_.
+//
+// As an optimization, there is a second vector<int> called right_ which
+// does not provide any new information. Instead, it enables more
+// efficient queries about edges entering or leaving the right-side nodes
+// of the flow or residual flow graphs. The following invariants are
+// maintained:

+// Google Mock - a framework for writing C++ mock classes.
+//
+// This file tests that:
+// a. A header file defining a mock class can be included in multiple
+// translation units without causing a link error.
+// b. Actions and matchers can be instantiated with identical template
+// arguments in different translation units without causing link
+// errors.
+// The following constructs are currently tested:
+// Actions:
+// Return()
+// Return(value)
+// ReturnNull
+// ReturnRef
+// Assign
+// SetArgPointee
+// SetArrayArgument
+// SetErrnoAndReturn
+// Invoke(function)
+// Invoke(object, method)
+// InvokeWithoutArgs(function)
+// InvokeWithoutArgs(object, method)
+// InvokeArgument
+// WithArg
+// WithArgs
+// WithoutArgs
+// DoAll
+// DoDefault
+// IgnoreResult
+// Throw
+// ACTION()-generated
+// ACTION_P()-generated
+// ACTION_P2()-generated
+// Matchers:
+// _
+// A
+// An
+// Eq
+// Gt, Lt, Ge, Le, Ne
+// NotNull
+// Ref
+// TypedEq
+// DoubleEq
+// FloatEq
+// NanSensitiveDoubleEq
+// NanSensitiveFloatEq
+// ContainsRegex
+// MatchesRegex
+// EndsWith
+// HasSubstr
+// StartsWith
+// StrCaseEq
+// StrCaseNe
+// StrEq
+// StrNe
+// ElementsAre
+// ElementsAreArray
+// ContainerEq
+// Field
+// Property
+// ResultOf(function)
+// ResultOf(callback)
+// Pointee
+// Truly(predicate)
+// AddressSatisfies
+// AllOf
+// AnyOf
+// Not
+// MatcherCast<T>
+//
+// Please note: this test does not verify the functioning of these
+// constructs, only that the programs using them will link successfully.
+//
+// Implementation note:
+// This test requires identical definitions of Interface and Mock to be
+// included in different translation units. We achieve this by writing
+// them in this header and #including it in gmock_link_test.cc and
+// gmock_link2_test.cc. Because the symbols generated by the compiler for
+// those constructs must be identical in both translation units,
+// definitions of Interface and Mock tests MUST be kept in the SAME
+// NON-ANONYMOUS namespace in this file. The test fixture class LinkTest
+// is defined as LinkTest1 in gmock_link_test.cc and as LinkTest2 in
+// gmock_link2_test.cc to avoid producing linker errors.

+ERROR: 3 leaked mock objects found at program exit. Expectations on a mock object is verified when the object is destructed. Leaking a mock means that its expectations aren't verified, which is usually a test bug. If you really intend to leak a mock, you can suppress this error using testing::Mock::AllowLeak(mock_object), or you may use a fake or stub instead of a mock.

+Changes for 1.7.0:
+
+* New feature: death tests are supported on OpenBSD and in iOS
+ simulator now.
+* New feature: Google Test now implements a protocol to allow
+ a test runner to detect that a test program has exited
+ prematurely and report it as a failure (before it would be
+ falsely reported as a success if the exit code is 0).
+* New feature: Test::RecordProperty() can now be used outside of the
+ lifespan of a test method, in which case it will be attributed to
+ the current test case or the test program in the XML report.
+* New feature (potentially breaking): --gtest_list_tests now prints
+ the type parameters and value parameters for each test.
+* Improvement: char pointers and char arrays are now escaped properly
+ in failure messages.
+* Improvement: failure summary in XML reports now includes file and
+ line information.
+* Improvement: the <testsuites> XML element now has a timestamp attribute.
+* Improvement: When --gtest_filter is specified, XML report now doesn't
+ contain information about tests that are filtered out.
+* Fixed the bug where long --gtest_filter flag values are truncated in
+ death tests.
+* Potentially breaking change: RUN_ALL_TESTS() is now implemented as a
+ function instead of a macro in order to work better with Clang.
+* Compatibility fixes with C++ 11 and various platforms.
+* Bug/warning fixes.
+
+Changes for 1.6.0:
+
+* New feature: ADD_FAILURE_AT() for reporting a test failure at the
+ given source location -- useful for writing testing utilities.
+* New feature: the universal value printer is moved from Google Mock
+ to Google Test.
+* New feature: type parameters and value parameters are reported in
+ the XML report now.
+* A gtest_disable_pthreads CMake option.
+* Colored output works in GNU Screen sessions now.
+* Parameters of value-parameterized tests are now printed in the
+ textual output.
+* Failures from ad hoc test assertions run before RUN_ALL_TESTS() are
+ now correctly reported.
+* Arguments of ASSERT_XY and EXPECT_XY no longer need to support << to
+ ostream.
+* More complete handling of exceptions.
+* GTEST_ASSERT_XY can be used instead of ASSERT_XY in case the latter
+ name is already used by another library.
+* --gtest_catch_exceptions is now true by default, allowing a test
+ program to continue after an exception is thrown.
+* Value-parameterized test fixtures can now derive from Test and
+ WithParamInterface<T> separately, easing conversion of legacy tests.
+* Death test messages are clearly marked to make them more
+ distinguishable from other messages.
+* Compatibility fixes for Android, Google Native Client, MinGW, HP UX,
+ PowerPC, Lucid autotools, libCStd, Sun C++, Borland C++ Builder (Code Gear),
+ IBM XL C++ (Visual Age C++), and C++0x.
+* Bug fixes and implementation clean-ups.
+* Potentially incompatible changes: disables the harmful 'make install'
+ command in autotools.
+
+Changes for 1.5.0:
+
+ * New feature: assertions can be safely called in multiple threads
+ where the pthreads library is available.
+ * New feature: predicates used inside EXPECT_TRUE() and friends
+ can now generate custom failure messages.
+ * New feature: Google Test can now be compiled as a DLL.
+ * New feature: fused source files are included.
+ * New feature: prints help when encountering unrecognized Google Test flags.
+ * Experimental feature: CMake build script (requires CMake 2.6.4+).
+ * Experimental feature: the Pump script for meta programming.
+ * double values streamed to an assertion are printed with enough precision
+ to differentiate any two different values.
+ * Google Test now works on Solaris and AIX.
+ * Build and test script improvements.
+ * Bug fixes and implementation clean-ups.
+
+ Potentially breaking changes:
+
+ * Stopped supporting VC++ 7.1 with exceptions disabled.
+ * Dropped support for 'make install'.
+
+Changes for 1.4.0:
+
+ * New feature: the event listener API
+ * New feature: test shuffling
+ * New feature: the XML report format is closer to junitreport and can
+ be parsed by Hudson now.
+ * New feature: when a test runs under Visual Studio, its failures are
+ integrated in the IDE.
+ * New feature: /MD(d) versions of VC++ projects.
+ * New feature: elapsed time for the tests is printed by default.
+ * New feature: comes with a TR1 tuple implementation such that Boost
+ is no longer needed for Combine().
+ * New feature: EXPECT_DEATH_IF_SUPPORTED macro and friends.
+ * New feature: the Xcode project can now produce static gtest
+ libraries in addition to a framework.
+ * Compatibility fixes for Solaris, Cygwin, minGW, Windows Mobile,
+ Symbian, gcc, and C++Builder.
+ * Bug fixes and implementation clean-ups.
+
+Changes for 1.3.0:
+
+ * New feature: death tests on Windows, Cygwin, and Mac.
+ * New feature: ability to use Google Test assertions in other testing
+ frameworks.
+ * New feature: ability to run disabled test via
+ --gtest_also_run_disabled_tests.
+ * New feature: the --help flag for printing the usage.
+ * New feature: access to Google Test flag values in user code.
+ * New feature: a script that packs Google Test into one .h and one
+ .cc file for easy deployment.
+ * New feature: support for distributing test functions to multiple
+ machines (requires support from the test runner).
+ * Bug fixes and implementation clean-ups.
+
+Changes for 1.2.1:
+
+ * Compatibility fixes for Linux IA-64 and IBM z/OS.
+ * Added support for using Boost and other TR1 implementations.
+ * Changes to the build scripts to support upcoming release of Google C++
+ Mocking Framework.
+ * Added Makefile to the distribution package.
+ * Improved build instructions in README.
+
+Changes for 1.2.0:
+
+ * New feature: value-parameterized tests.
+ * New feature: the ASSERT/EXPECT_(NON)FATAL_FAILURE(_ON_ALL_THREADS)
+ macros.
+ * Changed the XML report format to match JUnit/Ant's.
+ * Added tests to the Xcode project.
+ * Added scons/SConscript for building with SCons.
+ * Added src/gtest-all.cc for building Google Test from a single file.
+ * Fixed compatibility with Solaris and z/OS.
+ * Enabled running Python tests on systems with python 2.3 installed,
+ e.g. Mac OS X 10.4.
+ * Bug fixes.

+### Generic Build Instructions ###
+
+#### Setup ####
+
+To build Google Test and your tests that use it, you need to tell your
+build system where to find its headers and source files. The exact
+way to do it depends on which build system you use, and is usually
+straightforward.
+
+#### Build ####
+
+Suppose you put Google Test in directory `${GTEST_DIR}`. To build it,
+create a library build target (or a project as called by Visual Studio
+and Xcode) to compile
+
+ ${GTEST_DIR}/src/gtest-all.cc
+
+with `${GTEST_DIR}/include` in the system header search path and `${GTEST_DIR}`
+in the normal header search path. Assuming a Linux-like system and gcc,
+something like the following will do:
+
+ g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
+ -pthread -c ${GTEST_DIR}/src/gtest-all.cc
+ ar -rv libgtest.a gtest-all.o
+
+(We need `-pthread` as Google Test uses threads.)
+
+Next, you should compile your test source file with
+`${GTEST_DIR}/include` in the system header search path, and link it
+with gtest and any other necessary libraries:
+
+ g++ -isystem ${GTEST_DIR}/include -pthread path/to/your_test.cc libgtest.a \
+ -o your_test
+
+As an example, the make/ directory contains a Makefile that you can
+use to build Google Test on systems where GNU make is available
+(e.g. Linux, Mac OS X, and Cygwin). It doesn't try to build Google
+Test's own tests. Instead, it just builds the Google Test library and
+a sample test. You can use it as a starting point for your own build
+script.
+
+If the default settings are correct for your environment, the
+following commands should succeed:
+
+ cd ${GTEST_DIR}/make
+ make
+ ./sample1_unittest
+
+If you see errors, try to tweak the contents of `make/Makefile` to make
+them go away. There are instructions in `make/Makefile` on how to do
+it.
+
+### Using CMake ###
+
+Google Test comes with a CMake build script (
+[CMakeLists.txt](CMakeLists.txt)) that can be used on a wide range of platforms ("C" stands for
+cross-platform.). If you don't have CMake installed already, you can
+download it for free from <http://www.cmake.org/>.
+
+CMake works by generating native makefiles or build projects that can
+be used in the compiler environment of your choice. You can either
+build Google Test as a standalone project or it can be incorporated
+into an existing CMake build for another project.
+
+#### Standalone CMake Project ####
+
+When building Google Test as a standalone project, the typical
+workflow starts with:
+
+ mkdir mybuild # Create a directory to hold the build output.
+ cd mybuild
+ cmake ${GTEST_DIR} # Generate native build scripts.
+
+If you want to build Google Test's samples, you should replace the
+last command with
+
+ cmake -Dgtest_build_samples=ON ${GTEST_DIR}
+
+If you are on a \*nix system, you should now see a Makefile in the
+current directory. Just type 'make' to build gtest.
+
+If you use Windows and have Visual Studio installed, a `gtest.sln` file
+and several `.vcproj` files will be created. You can then build them
+using Visual Studio.
+
+On Mac OS X with Xcode installed, a `.xcodeproj` file will be generated.
+
+#### Incorporating Into An Existing CMake Project ####
+
+If you want to use gtest in a project which already uses CMake, then a
+more robust and flexible approach is to build gtest as part of that
+project directly. This is done by making the GoogleTest source code
+available to the main build and adding it using CMake's
+`add_subdirectory()` command. This has the significant advantage that
+the same compiler and linker settings are used between gtest and the
+rest of your project, so issues associated with using incompatible
+libraries (eg debug/release), etc. are avoided. This is particularly
+useful on Windows. Making GoogleTest's source code available to the
+main build can be done a few different ways:
+
+* Download the GoogleTest source code manually and place it at a
+ known location. This is the least flexible approach and can make
+ it more difficult to use with continuous integration systems, etc.
+* Embed the GoogleTest source code as a direct copy in the main
+ project's source tree. This is often the simplest approach, but is
+ also the hardest to keep up to date. Some organizations may not
+ permit this method.
+* Add GoogleTest as a git submodule or equivalent. This may not
+ always be possible or appropriate. Git submodules, for example,
+ have their own set of advantages and drawbacks.
+* Use CMake to download GoogleTest as part of the build's configure
+ step. This is just a little more complex, but doesn't have the
+ limitations of the other methods.
+
+The last of the above methods is implemented with a small piece
+of CMake code in a separate file (e.g. `CMakeLists.txt.in`) which
+is copied to the build area and then invoked as a sub-build
+_during the CMake stage_. That directory is then pulled into the
+main build with `add_subdirectory()`. For example:
+
+New file `CMakeLists.txt.in`:
+
+ cmake_minimum_required(VERSION 2.8.2)
+
+ project(googletest-download NONE)
+
+ include(ExternalProject)
+ ExternalProject_Add(googletest
+ GIT_REPOSITORY https://github.com/google/googletest.git
+ GIT_TAG master
+ SOURCE_DIR "${CMAKE_BINARY_DIR}/googletest-src"
+ BINARY_DIR "${CMAKE_BINARY_DIR}/googletest-build"
+ CONFIGURE_COMMAND ""
+ BUILD_COMMAND ""
+ INSTALL_COMMAND ""
+ TEST_COMMAND ""
+ )
+
+Existing build's `CMakeLists.txt`:
+
+ # Download and unpack googletest at configure time
+ configure_file(CMakeLists.txt.in googletest-download/CMakeLists.txt)
+ execute_process(COMMAND ${CMAKE_COMMAND} -G "${CMAKE_GENERATOR}" .
+ RESULT_VARIABLE result
+ WORKING_DIRECTORY ${CMAKE_BINARY_DIR}/googletest-download )
+ if(result)
+ message(FATAL_ERROR "CMake step for googletest failed: ${result}")
+ endif()
+ execute_process(COMMAND ${CMAKE_COMMAND} --build .
+ RESULT_VARIABLE result
+ WORKING_DIRECTORY ${CMAKE_BINARY_DIR}/googletest-download )
+ if(result)
+ message(FATAL_ERROR "Build step for googletest failed: ${result}")
+ endif()
+
+ # Prevent overriding the parent project's compiler/linker
+ # settings on Windows
+ set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
+
+ # Add googletest directly to our build. This defines
+ # the gtest and gtest_main targets.
+ add_subdirectory(${CMAKE_BINARY_DIR}/googletest-src
+ ${CMAKE_BINARY_DIR}/googletest-build
+ EXCLUDE_FROM_ALL)
+
+ # The gtest/gtest_main targets carry header search path
+ # dependencies automatically when using CMake 2.8.11 or
+ # later. Otherwise we have to add them here ourselves.
+ if (CMAKE_VERSION VERSION_LESS 2.8.11)
+ include_directories("${gtest_SOURCE_DIR}/include")
+ endif()
+
+ # Now simply link against gtest or gtest_main as needed. Eg
+ add_executable(example example.cpp)
+ target_link_libraries(example gtest_main)
+ add_test(NAME example_test COMMAND example)
+
+Note that this approach requires CMake 2.8.2 or later due to
+its use of the `ExternalProject_Add()` command. The above
+technique is discussed in more detail in
+[this separate article](http://crascit.com/2015/07/25/cmake-gtest/)
+which also contains a link to a fully generalized implementation
+of the technique.
+
+##### Visual Studio Dynamic vs Static Runtimes #####
+
+By default, new Visual Studio projects link the C runtimes dynamically
+but Google Test links them statically.
+This will generate an error that looks something like the following:
+ gtest.lib(gtest-all.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value 'MDd_DynamicDebug' in main.obj
+
+Google Test already has a CMake option for this: `gtest_force_shared_crt`
+
+Enabling this option will make gtest link the runtimes dynamically too,
+and match the project in which it is included.
+
+### Legacy Build Scripts ###
+
+Before settling on CMake, we have been providing hand-maintained build
+projects/scripts for Visual Studio, Xcode, and Autotools. While we
+continue to provide them for convenience, they are not actively
+maintained any more. We highly recommend that you follow the
+instructions in the above sections to integrate Google Test
+with your existing build system.
+
+If you still need to use the legacy build scripts, here's how:
+
+The msvc\ folder contains two solutions with Visual C++ projects.
+Open the `gtest.sln` or `gtest-md.sln` file using Visual Studio, and you
+are ready to build Google Test the same way you build any Visual
+Studio project. Files that have names ending with -md use DLL
+versions of Microsoft runtime libraries (the /MD or the /MDd compiler
+option). Files without that suffix use static versions of the runtime
+libraries (the /MT or the /MTd option). Please note that one must use
+the same option to compile both gtest and the test code. If you use
+Visual Studio 2005 or above, we recommend the -md version as /MD is
+the default for new projects in these versions of Visual Studio.
+
+On Mac OS X, open the `gtest.xcodeproj` in the `xcode/` folder using
+Xcode. Build the "gtest" target. The universal binary framework will
+end up in your selected build directory (selected in the Xcode
+"Preferences..." -> "Building" pane and defaults to xcode/build).
+Alternatively, at the command line, enter:
+
+ xcodebuild
+
+This will build the "Release" configuration of gtest.framework in your
+default build location. See the "xcodebuild" man page for more
+information about building different configurations and building in
+different locations.
+
+If you wish to use the Google Test Xcode project with Xcode 4.x and
+above, you need to either:
+
+ * update the SDK configuration options in xcode/Config/General.xconfig.
+ Comment options `SDKROOT`, `MACOS_DEPLOYMENT_TARGET`, and `GCC_VERSION`. If
+ you choose this route you lose the ability to target earlier versions
+ of MacOS X.
+ * Install an SDK for an earlier version. This doesn't appear to be
+ supported by Apple, but has been reported to work
+ (http://stackoverflow.com/questions/5378518).
+
+### Tweaking Google Test ###
+
+Google Test can be used in diverse environments. The default
+configuration may not work (or may not work well) out of the box in
+some environments. However, you can easily tweak Google Test by
+defining control macros on the compiler command line. Generally,
+these macros are named like `GTEST_XYZ` and you define them to either 1
+or 0 to enable or disable a certain feature.
+
+We list the most frequently used macros below. For a complete list,

+### Choosing a TR1 Tuple Library ###
+
+Some Google Test features require the C++ Technical Report 1 (TR1)
+tuple library, which is not yet available with all compilers. The
+good news is that Google Test implements a subset of TR1 tuple that's
+enough for its own need, and will automatically use this when the
+compiler doesn't provide TR1 tuple.
+
+Usually you don't need to care about which tuple library Google Test
+uses. However, if your project already uses TR1 tuple, you need to
+tell Google Test to use the same TR1 tuple library the rest of your
+project uses, or the two tuple implementations will clash. To do
+that, add
+
+ -DGTEST_USE_OWN_TR1_TUPLE=0
+
+to the compiler flags while compiling Google Test and your tests. If
+you want to force Google Test to use its own tuple library, just add
+
+ -DGTEST_USE_OWN_TR1_TUPLE=1
+
+to the compiler flags instead.
+
+If you don't want Google Test to use tuple at all, add
+
+ -DGTEST_HAS_TR1_TUPLE=0
+
+and all features using tuple will be disabled.
+
+### Multi-threaded Tests ###
+
+Google Test is thread-safe where the pthread library is available.
+After `#include "gtest/gtest.h"`, you can check the `GTEST_IS_THREADSAFE`
+macro to see whether this is the case (yes if the macro is `#defined` to
+1, no if it's undefined.).
+
+If Google Test doesn't correctly detect whether pthread is available
+in your environment, you can force it with
+
+ -DGTEST_HAS_PTHREAD=1
+
+or
+
+ -DGTEST_HAS_PTHREAD=0
+
+When Google Test uses pthread, you may need to add flags to your
+compiler and/or linker to select the pthread library, or you'll get
+link errors. If you use the CMake script or the deprecated Autotools
+script, this is taken care of for you. If you use your own build
+script, you'll need to read your compiler and linker's manual to
+figure out what flags to add.
+
+### As a Shared Library (DLL) ###
+
+Google Test is compact, so most users can build and link it as a
+static library for the simplicity. You can choose to use Google Test
+as a shared library (known as a DLL on Windows) if you prefer.
+
+To compile *gtest* as a shared library, add
+
+ -DGTEST_CREATE_SHARED_LIBRARY=1
+
+to the compiler flags. You'll also need to tell the linker to produce
+a shared library instead - consult your linker's manual for how to do
+it.
+
+To compile your *tests* that use the gtest shared library, add
+
+ -DGTEST_LINKED_AS_SHARED_LIBRARY=1
+
+to the compiler flags.
+
+Note: while the above steps aren't technically necessary today when
+using some compilers (e.g. GCC), they may become necessary in the
+future, if we decide to improve the speed of loading the library (see
+<http://gcc.gnu.org/wiki/Visibility> for details). Therefore you are
+recommended to always add the above flags when using Google Test as a
+shared library. Otherwise a future release of Google Test may break
+your build script.
+
+### Avoiding Macro Name Clashes ###
+
+In C++, macros don't obey namespaces. Therefore two libraries that
+both define a macro of the same name will clash if you `#include` both
+definitions. In case a Google Test macro clashes with another
+library, you can force Google Test to rename its macro to avoid the
+conflict.
+
+Specifically, if both Google Test and some other code define macro
+FOO, you can add
+
+ -DGTEST_DONT_DEFINE_FOO=1
+
+to the compiler flags to tell Google Test to change the macro's name
+from `FOO` to `GTEST_FOO`. Currently `FOO` can be `FAIL`, `SUCCEED`,
+or `TEST`. For example, with `-DGTEST_DONT_DEFINE_TEST=1`, you'll
+need to write
+
+ GTEST_TEST(SomeTest, DoesThis) { ... }
+
+instead of
+
+ TEST(SomeTest, DoesThis) { ... }
+
+in order to define a test.

+
+Now that you have read [Primer](Primer.md) and learned how to write tests
+using Google Test, it's time to learn some new tricks. This document
+will show you more assertions as well as how to construct complex
+failure messages, propagate fatal failures, reuse and speed up your
+test fixtures, and use various flags with your tests.
+
+# More Assertions #
+
+This section covers some less frequently used, but still significant,
+assertions.
+
+## Explicit Success and Failure ##
+
+These three assertions do not actually test a value or expression. Instead,
+they generate a success or failure directly. Like the macros that actually
+perform a test, you may stream a custom failure message into them.
+
+| `SUCCEED();` |
+|:-------------|
+
+Generates a success. This does NOT make the overall test succeed. A test is
+considered successful only if none of its assertions fail during its execution.
+
+Note: `SUCCEED()` is purely documentary and currently doesn't generate any
+user-visible output. However, we may add `SUCCEED()` messages to Google Test's
+output in the future.
+
+| `FAIL();` | `ADD_FAILURE();` | `ADD_FAILURE_AT("`_file\_path_`", `_line\_number_`);` |
+|:-----------|:-----------------|:------------------------------------------------------|
+
+`FAIL()` generates a fatal failure, while `ADD_FAILURE()` and `ADD_FAILURE_AT()` generate a nonfatal
+failure. These are useful when control flow, rather than a Boolean expression,
+determines the test's success or failure. For example, you might want to write
+something like:
+
+```
+switch(expression) {
+ case 1: ... some checks ...
+ case 2: ... some other checks
+ ...
+ default: FAIL() << "We shouldn't get here.";
+}
+```
+
+Note: you can only use `FAIL()` in functions that return `void`. See the [Assertion Placement section](#assertion-placement) for more information.
+
+_Availability_: Linux, Windows, Mac.
+
+## Exception Assertions ##
+
+These are for verifying that a piece of code throws (or does not
+throw) an exception of the given type:
+
+| **Fatal assertion** | **Nonfatal assertion** | **Verifies** |
+|:--------------------|:-----------------------|:-------------|
+| `ASSERT_THROW(`_statement_, _exception\_type_`);` | `EXPECT_THROW(`_statement_, _exception\_type_`);` | _statement_ throws an exception of the given type |
+| `ASSERT_ANY_THROW(`_statement_`);` | `EXPECT_ANY_THROW(`_statement_`);` | _statement_ throws an exception of any type |
+| `ASSERT_NO_THROW(`_statement_`);` | `EXPECT_NO_THROW(`_statement_`);` | _statement_ doesn't throw any exception |
+
+Examples:
+
+```
+ASSERT_THROW(Foo(5), bar_exception);
+
+EXPECT_NO_THROW({
+ int n = 5;
+ Bar(&n);
+});
+```
+
+_Availability_: Linux, Windows, Mac; since version 1.1.0.
+
+## Predicate Assertions for Better Error Messages ##
+
+Even though Google Test has a rich set of assertions, they can never be
+complete, as it's impossible (nor a good idea) to anticipate all the scenarios
+a user might run into. Therefore, sometimes a user has to use `EXPECT_TRUE()`
+to check a complex expression, for lack of a better macro. This has the problem
+of not showing you the values of the parts of the expression, making it hard to
+understand what went wrong. As a workaround, some users choose to construct the
+failure message by themselves, streaming it into `EXPECT_TRUE()`. However, this
+is awkward especially when the expression has side-effects or is expensive to
+evaluate.
+
+Google Test gives you three different options to solve this problem:
+
+### Using an Existing Boolean Function ###
+
+If you already have a function or a functor that returns `bool` (or a type
+that can be implicitly converted to `bool`), you can use it in a _predicate
+assertion_ to get the function arguments printed for free:
+
+| **Fatal assertion** | **Nonfatal assertion** | **Verifies** |
+|:--------------------|:-----------------------|:-------------|
+| `ASSERT_PRED1(`_pred1, val1_`);` | `EXPECT_PRED1(`_pred1, val1_`);` | _pred1(val1)_ returns true |
+| `ASSERT_PRED2(`_pred2, val1, val2_`);` | `EXPECT_PRED2(`_pred2, val1, val2_`);` | _pred2(val1, val2)_ returns true |
+| ... | ... | ... |
+
+In the above, _predn_ is an _n_-ary predicate function or functor, where
+_val1_, _val2_, ..., and _valn_ are its arguments. The assertion succeeds
+if the predicate returns `true` when applied to the given arguments, and fails
+otherwise. When the assertion fails, it prints the value of each argument. In
+either case, the arguments are evaluated exactly once.
+
+Here's an example. Given
+
+```
+// Returns true iff m and n have no common divisors except 1.
+bool MutuallyPrime(int m, int n) { ... }
+const int a = 3;
+const int b = 4;
+const int c = 10;
+```
+
+the assertion `EXPECT_PRED2(MutuallyPrime, a, b);` will succeed, while the
+assertion `EXPECT_PRED2(MutuallyPrime, b, c);` will fail with the message
+
+<pre>
+!MutuallyPrime(b, c) is false, where<br>
+b is 4<br>
+c is 10<br>
+</pre>
+
+**Notes:**
+
+ 1. If you see a compiler error "no matching function to call" when using `ASSERT_PRED*` or `EXPECT_PRED*`, please see [this FAQ](FAQ.md#the-compiler-complains-no-matching-function-to-call-when-i-use-assert_predn-how-do-i-fix-it) for how to resolve it.
+ 1. Currently we only provide predicate assertions of arity <= 5. If you need a higher-arity assertion, let us know.
+
+_Availability_: Linux, Windows, Mac.
+
+### Using a Function That Returns an AssertionResult ###
+
+While `EXPECT_PRED*()` and friends are handy for a quick job, the
+syntax is not satisfactory: you have to use different macros for
+different arities, and it feels more like Lisp than C++. The
+`::testing::AssertionResult` class solves this problem.
+
+An `AssertionResult` object represents the result of an assertion
+(whether it's a success or a failure, and an associated message). You
+can create an `AssertionResult` using one of these factory
+functions:
+
+```
+namespace testing {
+
+// Returns an AssertionResult object to indicate that an assertion has
+// succeeded.
+AssertionResult AssertionSuccess();
+
+// Returns an AssertionResult object to indicate that an assertion has
+// failed.
+AssertionResult AssertionFailure();
+
+}
+```
+
+You can then use the `<<` operator to stream messages to the
+`AssertionResult` object.
+
+To provide more readable messages in Boolean assertions
+(e.g. `EXPECT_TRUE()`), write a predicate function that returns
+`AssertionResult` instead of `bool`. For example, if you define
+`IsEven()` as:
+
+```
+::testing::AssertionResult IsEven(int n) {
+ if ((n % 2) == 0)
+ return ::testing::AssertionSuccess();
+ else
+ return ::testing::AssertionFailure() << n << " is odd";
+}
+```
+
+instead of:
+
+```
+bool IsEven(int n) {
+ return (n % 2) == 0;
+}
+```
+
+the failed assertion `EXPECT_TRUE(IsEven(Fib(4)))` will print:
+
+<pre>
+Value of: IsEven(Fib(4))<br>
+Actual: false (*3 is odd*)<br>
+Expected: true<br>
+</pre>
+
+instead of a more opaque
+
+<pre>
+Value of: IsEven(Fib(4))<br>
+Actual: false<br>
+Expected: true<br>
+</pre>
+
+If you want informative messages in `EXPECT_FALSE` and `ASSERT_FALSE`
+as well, and are fine with making the predicate slower in the success
+case, you can supply a success message:
+
+```
+::testing::AssertionResult IsEven(int n) {
+ if ((n % 2) == 0)
+ return ::testing::AssertionSuccess() << n << " is even";
+ else
+ return ::testing::AssertionFailure() << n << " is odd";
+}
+```
+
+Then the statement `EXPECT_FALSE(IsEven(Fib(6)))` will print
+
+<pre>
+Value of: IsEven(Fib(6))<br>
+Actual: true (8 is even)<br>
+Expected: false<br>
+</pre>
+
+_Availability_: Linux, Windows, Mac; since version 1.4.1.
+
+### Using a Predicate-Formatter ###
+
+If you find the default message generated by `(ASSERT|EXPECT)_PRED*` and
+`(ASSERT|EXPECT)_(TRUE|FALSE)` unsatisfactory, or some arguments to your
+predicate do not support streaming to `ostream`, you can instead use the
+following _predicate-formatter assertions_ to _fully_ customize how the
+message is formatted:
+
+| **Fatal assertion** | **Nonfatal assertion** | **Verifies** |
+|:--------------------|:-----------------------|:-------------|
+| `ASSERT_PRED_FORMAT1(`_pred\_format1, val1_`);` | `EXPECT_PRED_FORMAT1(`_pred\_format1, val1_`);` | _pred\_format1(val1)_ is successful |
+| `ASSERT_PRED_FORMAT2(`_pred\_format2, val1, val2_`);` | `EXPECT_PRED_FORMAT2(`_pred\_format2, val1, val2_`);` | _pred\_format2(val1, val2)_ is successful |
+| `...` | `...` | `...` |
+
+The difference between this and the previous two groups of macros is that instead of
+a predicate, `(ASSERT|EXPECT)_PRED_FORMAT*` take a _predicate-formatter_
+(_pred\_formatn_), which is a function or functor with the signature:
+
+`::testing::AssertionResult PredicateFormattern(const char* `_expr1_`, const char* `_expr2_`, ... const char* `_exprn_`, T1 `_val1_`, T2 `_val2_`, ... Tn `_valn_`);`
+
+where _val1_, _val2_, ..., and _valn_ are the values of the predicate
+arguments, and _expr1_, _expr2_, ..., and _exprn_ are the corresponding
+expressions as they appear in the source code. The types `T1`, `T2`, ..., and
+`Tn` can be either value types or reference types. For example, if an
+argument has type `Foo`, you can declare it as either `Foo` or `const Foo&`,
+whichever is appropriate.
+
+A predicate-formatter returns a `::testing::AssertionResult` object to indicate
+whether the assertion has succeeded or not. The only way to create such an
+object is to call one of these factory functions:
+
+As an example, let's improve the failure message in the previous example, which uses `EXPECT_PRED2()`:
+
+```
+// Returns the smallest prime common divisor of m and n,
+// or 1 when m and n are mutually prime.
+int SmallestPrimeCommonDivisor(int m, int n) { ... }
+
+// A predicate-formatter for asserting that two integers are mutually prime.
+::testing::AssertionResult AssertMutuallyPrime(const char* m_expr,
+ const char* n_expr,
+ int m,
+ int n) {
+ if (MutuallyPrime(m, n))
+ return ::testing::AssertionSuccess();
+
+ return ::testing::AssertionFailure()
+ << m_expr << " and " << n_expr << " (" << m << " and " << n
+ << ") are not mutually prime, " << "as they have a common divisor "
+ << SmallestPrimeCommonDivisor(m, n);
+}
+```
+
+With this predicate-formatter, we can use
+
+```
+EXPECT_PRED_FORMAT2(AssertMutuallyPrime, b, c);
+```
+
+to generate the message
+
+<pre>
+b and c (4 and 10) are not mutually prime, as they have a common divisor 2.<br>
+</pre>
+
+As you may have realized, many of the assertions we introduced earlier are
+special cases of `(EXPECT|ASSERT)_PRED_FORMAT*`. In fact, most of them are
+indeed defined using `(EXPECT|ASSERT)_PRED_FORMAT*`.

+
+## Floating-Point Comparison ##
+
+Comparing floating-point numbers is tricky. Due to round-off errors, it is
+very unlikely that two floating-points will match exactly. Therefore,
+`ASSERT_EQ` 's naive comparison usually doesn't work. And since floating-points
+can have a wide value range, no single fixed error bound works. It's better to
+compare by a fixed relative error bound, except for values close to 0 due to
+the loss of precision there.
+
+In general, for floating-point comparison to make sense, the user needs to
+carefully choose the error bound. If they don't want or care to, comparing in
+terms of Units in the Last Place (ULPs) is a good default, and Google Test
+provides assertions to do this. Full details about ULPs are quite long; if you
+want to learn more, see
+[this article on float comparison](https://randomascii.wordpress.com/2012/02/25/comparing-floating-point-numbers-2012-edition/).
+
+### Floating-Point Macros ###
+
+| **Fatal assertion** | **Nonfatal assertion** | **Verifies** |
+|:--------------------|:-----------------------|:-------------|
+| `ASSERT_FLOAT_EQ(`_val1, val2_`);` | `EXPECT_FLOAT_EQ(`_val1, val2_`);` | the two `float` values are almost equal |
+| `ASSERT_DOUBLE_EQ(`_val1, val2_`);` | `EXPECT_DOUBLE_EQ(`_val1, val2_`);` | the two `double` values are almost equal |
+
+By "almost equal", we mean the two values are within 4 ULP's from each
+other.
+
+The following assertions allow you to choose the acceptable error bound:
+
+| **Fatal assertion** | **Nonfatal assertion** | **Verifies** |
+|:--------------------|:-----------------------|:-------------|
+| `ASSERT_NEAR(`_val1, val2, abs\_error_`);` | `EXPECT_NEAR`_(val1, val2, abs\_error_`);` | the difference between _val1_ and _val2_ doesn't exceed the given absolute error |
+
+_Availability_: Linux, Windows, Mac.
+
+### Floating-Point Predicate-Format Functions ###
+
+Some floating-point operations are useful, but not that often used. In order
+to avoid an explosion of new macros, we provide them as predicate-format
+functions that can be used in predicate assertion macros (e.g.
+`EXPECT_PRED_FORMAT2`, etc).
+
+```
+EXPECT_PRED_FORMAT2(::testing::FloatLE, val1, val2);
+EXPECT_PRED_FORMAT2(::testing::DoubleLE, val1, val2);
+```
+
+Verifies that _val1_ is less than, or almost equal to, _val2_. You can
+replace `EXPECT_PRED_FORMAT2` in the above table with `ASSERT_PRED_FORMAT2`.
+
+_Availability_: Linux, Windows, Mac.
+
+## Windows HRESULT assertions ##
+
+These assertions test for `HRESULT` success or failure.
+
+| **Fatal assertion** | **Nonfatal assertion** | **Verifies** |
+|:--------------------|:-----------------------|:-------------|
+| `ASSERT_HRESULT_SUCCEEDED(`_expression_`);` | `EXPECT_HRESULT_SUCCEEDED(`_expression_`);` | _expression_ is a success `HRESULT` |
+| `ASSERT_HRESULT_FAILED(`_expression_`);` | `EXPECT_HRESULT_FAILED(`_expression_`);` | _expression_ is a failure `HRESULT` |
+
+The generated output contains the human-readable error message
+associated with the `HRESULT` code returned by _expression_.
+
+You might use them like this:
+
+```
+CComPtr shell;
+ASSERT_HRESULT_SUCCEEDED(shell.CoCreateInstance(L"Shell.Application"));
+CComVariant empty;
+ASSERT_HRESULT_SUCCEEDED(shell->ShellExecute(CComBSTR(url), empty, empty, empty, empty));
+```
+
+_Availability_: Windows.
+
+## Type Assertions ##
+
+You can call the function
+```
+::testing::StaticAssertTypeEq<T1, T2>();
+```
+to assert that types `T1` and `T2` are the same. The function does
+nothing if the assertion is satisfied. If the types are different,
+the function call will fail to compile, and the compiler error message
+will likely (depending on the compiler) show you the actual values of
+`T1` and `T2`. This is mainly useful inside template code.
+
+_Caveat:_ When used inside a member function of a class template or a
+function template, `StaticAssertTypeEq<T1, T2>()` is effective _only if_
+the function is instantiated. For example, given:
+```
+template <typename T> class Foo {
+ public:
+ void Bar() { ::testing::StaticAssertTypeEq<int, T>(); }
+};
+```
+the code:
+```
+void Test1() { Foo<bool> foo; }
+```
+will _not_ generate a compiler error, as `Foo<bool>::Bar()` is never
+actually instantiated. Instead, you need:
+```
+void Test2() { Foo<bool> foo; foo.Bar(); }
+```
+to cause a compiler error.
+
+_Availability:_ Linux, Windows, Mac; since version 1.3.0.
+
+## Assertion Placement ##
+
+You can use assertions in any C++ function. In particular, it doesn't
+have to be a method of the test fixture class. The one constraint is
+that assertions that generate a fatal failure (`FAIL*` and `ASSERT_*`)
+can only be used in void-returning functions. This is a consequence of
+Google Test not using exceptions. By placing it in a non-void function
+you'll get a confusing compile error like
+`"error: void value not ignored as it ought to be"`.
+
+If you need to use assertions in a function that returns non-void, one option
+is to make the function return the value in an out parameter instead. For
+example, you can rewrite `T2 Foo(T1 x)` to `void Foo(T1 x, T2* result)`. You
+need to make sure that `*result` contains some sensible value even when the
+function returns prematurely. As the function now returns `void`, you can use
+any assertion inside of it.
+
+If changing the function's type is not an option, you should just use
+assertions that generate non-fatal failures, such as `ADD_FAILURE*` and
+`EXPECT_*`.
+
+_Note_: Constructors and destructors are not considered void-returning
+functions, according to the C++ language specification, and so you may not use
+fatal assertions in them. You'll get a compilation error if you try. A simple
+workaround is to transfer the entire body of the constructor or destructor to a
+private void-returning method. However, you should be aware that a fatal
+assertion failure in a constructor does not terminate the current test, as your
+intuition might suggest; it merely returns from the constructor early, possibly
+leaving your object in a partially-constructed state. Likewise, a fatal
+assertion failure in a destructor may leave your object in a
+partially-destructed state. Use assertions carefully in these situations!
+
+# Teaching Google Test How to Print Your Values #
+
+When a test assertion such as `EXPECT_EQ` fails, Google Test prints the
+argument values to help you debug. It does this using a
+user-extensible value printer.
+
+This printer knows how to print built-in C++ types, native arrays, STL
+containers, and any type that supports the `<<` operator. For other
+types, it prints the raw bytes in the value and hopes that you the
+user can figure it out.
+
+As mentioned earlier, the printer is _extensible_. That means
+you can teach it to do a better job at printing your particular type
+than to dump the bytes. To do that, define `<<` for your type:
+
+```
+#include <iostream>
+
+namespace foo {
+
+class Bar { ... }; // We want Google Test to be able to print instances of this.
+
+// It's important that the << operator is defined in the SAME
+// namespace that defines Bar. C++'s look-up rules rely on that.
+::std::ostream& operator<<(::std::ostream& os, const Bar& bar) {
+ return os << bar.DebugString(); // whatever needed to print bar to os
+}
+
+} // namespace foo
+```
+
+Sometimes, this might not be an option: your team may consider it bad
+style to have a `<<` operator for `Bar`, or `Bar` may already have a
+`<<` operator that doesn't do what you want (and you cannot change
+it). If so, you can instead define a `PrintTo()` function like this:
+
+```
+#include <iostream>
+
+namespace foo {
+
+class Bar { ... };
+
+// It's important that PrintTo() is defined in the SAME
+// namespace that defines Bar. C++'s look-up rules rely on that.
+void PrintTo(const Bar& bar, ::std::ostream* os) {
+ *os << bar.DebugString(); // whatever needed to print bar to os
+}
+
+} // namespace foo
+```
+
+If you have defined both `<<` and `PrintTo()`, the latter will be used
+when Google Test is concerned. This allows you to customize how the value
+appears in Google Test's output without affecting code that relies on the
+behavior of its `<<` operator.
+
+If you want to print a value `x` using Google Test's value printer
+yourself, just call `::testing::PrintToString(`_x_`)`, which
+returns an `std::string`:
+
+```
+vector<pair<Bar, int> > bar_ints = GetBarIntVector();
+
+EXPECT_TRUE(IsCorrectBarIntVector(bar_ints))
+ << "bar_ints = " << ::testing::PrintToString(bar_ints);
+```
+
+# Death Tests #
+
+In many applications, there are assertions that can cause application failure
+if a condition is not met. These sanity checks, which ensure that the program
+is in a known good state, are there to fail at the earliest possible time after
+some program state is corrupted. If the assertion checks the wrong condition,
+then the program may proceed in an erroneous state, which could lead to memory
+corruption, security holes, or worse. Hence it is vitally important to test
+that such assertion statements work as expected.
+
+Since these precondition checks cause the processes to die, we call such tests
+_death tests_. More generally, any test that checks that a program terminates
+(except by throwing an exception) in an expected fashion is also a death test.
+
+Note that if a piece of code throws an exception, we don't consider it "death"
+for the purpose of death tests, as the caller of the code could catch the exception
+and avoid the crash. If you want to verify exceptions thrown by your code,
+see [Exception Assertions](#exception-assertions).
+
+If you want to test `EXPECT_*()/ASSERT_*()` failures in your test code, see [Catching Failures](#catching-failures).
+
+## How to Write a Death Test ##
+
+Google Test has the following macros to support death tests:
+
+| **Fatal assertion** | **Nonfatal assertion** | **Verifies** |
+|:--------------------|:-----------------------|:-------------|
+| `ASSERT_DEATH(`_statement, regex_`);` | `EXPECT_DEATH(`_statement, regex_`);` | _statement_ crashes with the given error |
+| `ASSERT_DEATH_IF_SUPPORTED(`_statement, regex_`);` | `EXPECT_DEATH_IF_SUPPORTED(`_statement, regex_`);` | if death tests are supported, verifies that _statement_ crashes with the given error; otherwise verifies nothing |
+| `ASSERT_EXIT(`_statement, predicate, regex_`);` | `EXPECT_EXIT(`_statement, predicate, regex_`);` |_statement_ exits with the given error and its exit code matches _predicate_ |
+
+where _statement_ is a statement that is expected to cause the process to
+die, _predicate_ is a function or function object that evaluates an integer
+exit status, and _regex_ is a regular expression that the stderr output of
+_statement_ is expected to match. Note that _statement_ can be _any valid
+statement_ (including _compound statement_) and doesn't have to be an
+expression.
+
+As usual, the `ASSERT` variants abort the current test function, while the
+`EXPECT` variants do not.
+
+**Note:** We use the word "crash" here to mean that the process
+terminates with a _non-zero_ exit status code. There are two
+possibilities: either the process has called `exit()` or `_exit()`
+with a non-zero value, or it may be killed by a signal.
+
+This means that if _statement_ terminates the process with a 0 exit
+code, it is _not_ considered a crash by `EXPECT_DEATH`. Use
+`EXPECT_EXIT` instead if this is the case, or if you want to restrict
+the exit code more precisely.
+
+A predicate here must accept an `int` and return a `bool`. The death test
+succeeds only if the predicate returns `true`. Google Test defines a few
+predicates that handle the most common cases:
+
+```
+::testing::ExitedWithCode(exit_code)
+```
+
+This expression is `true` if the program exited normally with the given exit
+code.
+
+```
+::testing::KilledBySignal(signal_number) // Not available on Windows.
+```
+
+This expression is `true` if the program was killed by the given signal.
+
+The `*_DEATH` macros are convenient wrappers for `*_EXIT` that use a predicate
+that verifies the process' exit code is non-zero.
+
+Note that a death test only cares about three things:
+
+ 1. does _statement_ abort or exit the process?
+ 1. (in the case of `ASSERT_EXIT` and `EXPECT_EXIT`) does the exit status satisfy _predicate_? Or (in the case of `ASSERT_DEATH` and `EXPECT_DEATH`) is the exit status non-zero? And
+ 1. does the stderr output match _regex_?
+
+In particular, if _statement_ generates an `ASSERT_*` or `EXPECT_*` failure, it will **not** cause the death test to fail, as Google Test assertions don't abort the process.
+
+To write a death test, simply use one of the above macros inside your test
+function. For example,
+
+```
+TEST(MyDeathTest, Foo) {
+ // This death test uses a compound statement.
+ ASSERT_DEATH({ int n = 5; Foo(&n); }, "Error on line .* of Foo()");
+}
+TEST(MyDeathTest, NormalExit) {
+ EXPECT_EXIT(NormalExit(), ::testing::ExitedWithCode(0), "Success");
+}
+TEST(MyDeathTest, KillMyself) {
+ EXPECT_EXIT(KillMyself(), ::testing::KilledBySignal(SIGKILL), "Sending myself unblockable signal");
+}
+```
+
+verifies that:
+
+ * calling `Foo(5)` causes the process to die with the given error message,
+ * calling `NormalExit()` causes the process to print `"Success"` to stderr and exit with exit code 0, and
+ * calling `KillMyself()` kills the process with signal `SIGKILL`.
+
+The test function body may contain other assertions and statements as well, if
+necessary.
+
+_Important:_ We strongly recommend you to follow the convention of naming your
+test case (not test) `*DeathTest` when it contains a death test, as
+demonstrated in the above example. The `Death Tests And Threads` section below
+explains why.
+
+If a test fixture class is shared by normal tests and death tests, you
+can use typedef to introduce an alias for the fixture class and avoid
+duplicating its code:
+```
+class FooTest : public ::testing::Test { ... };
+
+typedef FooTest FooDeathTest;
+
+TEST_F(FooTest, DoesThis) {
+ // normal test
+}
+
+TEST_F(FooDeathTest, DoesThat) {
+ // death test
+}
+```
+
+_Availability:_ Linux, Windows (requires MSVC 8.0 or above), Cygwin, and Mac (the latter three are supported since v1.3.0). `(ASSERT|EXPECT)_DEATH_IF_SUPPORTED` are new in v1.4.0.
+
+## Regular Expression Syntax ##
+
+On POSIX systems (e.g. Linux, Cygwin, and Mac), Google Test uses the
+[POSIX extended regular expression](http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap09.html#tag_09_04)
+syntax in death tests. To learn about this syntax, you may want to read this [Wikipedia entry](http://en.wikipedia.org/wiki/Regular_expression#POSIX_Extended_Regular_Expressions).
+
+On Windows, Google Test uses its own simple regular expression
+implementation. It lacks many features you can find in POSIX extended
+regular expressions. For example, we don't support union (`"x|y"`),
+grouping (`"(xy)"`), brackets (`"[xy]"`), and repetition count
+(`"x{5,7}"`), among others. Below is what we do support (Letter `A` denotes a
+literal character, period (`.`), or a single `\\` escape sequence; `x`
+and `y` denote regular expressions.):
+
+| `c` | matches any literal character `c` |
+|:----|:----------------------------------|
+| `\\d` | matches any decimal digit |
+| `\\D` | matches any character that's not a decimal digit |
+| `\\f` | matches `\f` |
+| `\\n` | matches `\n` |
+| `\\r` | matches `\r` |
+| `\\s` | matches any ASCII whitespace, including `\n` |
+| `\\S` | matches any character that's not a whitespace |
+| `\\t` | matches `\t` |
+| `\\v` | matches `\v` |
+| `\\w` | matches any letter, `_`, or decimal digit |
+| `\\W` | matches any character that `\\w` doesn't match |
+| `\\c` | matches any literal character `c`, which must be a punctuation |
+| `\\.` | matches the `.` character |
+| `.` | matches any single character except `\n` |
+| `A?` | matches 0 or 1 occurrences of `A` |
+| `A*` | matches 0 or many occurrences of `A` |
+| `A+` | matches 1 or many occurrences of `A` |
+| `^` | matches the beginning of a string (not that of each line) |
+| `$` | matches the end of a string (not that of each line) |
+| `xy` | matches `x` followed by `y` |
+
+To help you determine which capability is available on your system,
+Google Test defines macro `GTEST_USES_POSIX_RE=1` when it uses POSIX
+extended regular expressions, or `GTEST_USES_SIMPLE_RE=1` when it uses
+the simple version. If you want your death tests to work in both
+cases, you can either `#if` on these macros or use the more limited
+syntax only.
+
+## How It Works ##
+
+Under the hood, `ASSERT_EXIT()` spawns a new process and executes the
+death test statement in that process. The details of how precisely
+that happens depend on the platform and the variable
+`::testing::GTEST_FLAG(death_test_style)` (which is initialized from the
+command-line flag `--gtest_death_test_style`).
+
+ * On POSIX systems, `fork()` (or `clone()` on Linux) is used to spawn the child, after which:
+ * If the variable's value is `"fast"`, the death test statement is immediately executed.
+ * If the variable's value is `"threadsafe"`, the child process re-executes the unit test binary just as it was originally invoked, but with some extra flags to cause just the single death test under consideration to be run.
+ * On Windows, the child is spawned using the `CreateProcess()` API, and re-executes the binary to cause just the single death test under consideration to be run - much like the `threadsafe` mode on POSIX.
+
+Other values for the variable are illegal and will cause the death test to
+fail. Currently, the flag's default value is `"fast"`. However, we reserve the
+right to change it in the future. Therefore, your tests should not depend on
+this.
+
+In either case, the parent process waits for the child process to complete, and checks that
+
+ 1. the child's exit status satisfies the predicate, and
+ 1. the child's stderr matches the regular expression.
+
+If the death test statement runs to completion without dying, the child
+process will nonetheless terminate, and the assertion fails.
+
+## Death Tests And Threads ##
+
+The reason for the two death test styles has to do with thread safety. Due to
+well-known problems with forking in the presence of threads, death tests should
+be run in a single-threaded context. Sometimes, however, it isn't feasible to
+arrange that kind of environment. For example, statically-initialized modules
+may start threads before main is ever reached. Once threads have been created,
+it may be difficult or impossible to clean them up.
+
+Google Test has three features intended to raise awareness of threading issues.
+
+ 1. A warning is emitted if multiple threads are running when a death test is encountered.
+ 1. Test cases with a name ending in "DeathTest" are run before all other tests.
+ 1. It uses `clone()` instead of `fork()` to spawn the child process on Linux (`clone()` is not available on Cygwin and Mac), as `fork()` is more likely to cause the child to hang when the parent process has multiple threads.
+
+It's perfectly fine to create threads inside a death test statement; they are
+executed in a separate process and cannot affect the parent.
+
+## Death Test Styles ##
+
+The "threadsafe" death test style was introduced in order to help mitigate the
+risks of testing in a possibly multithreaded environment. It trades increased
+test execution time (potentially dramatically so) for improved thread safety.
+We suggest using the faster, default "fast" style unless your test has specific
+problems with it.
+
+You can choose a particular style of death tests by setting the flag
+programmatically:
+
+```
+::testing::FLAGS_gtest_death_test_style = "threadsafe";
+```
+
+You can do this in `main()` to set the style for all death tests in the
+binary, or in individual tests. Recall that flags are saved before running each
+test and restored afterwards, so you need not do that yourself. For example:
+
+```
+TEST(MyDeathTest, TestOne) {
+ ::testing::FLAGS_gtest_death_test_style = "threadsafe";
+ // This test is run in the "threadsafe" style:
+ ASSERT_DEATH(ThisShouldDie(), "");
+}
+
+TEST(MyDeathTest, TestTwo) {
+ // This test is run in the "fast" style:
+ ASSERT_DEATH(ThisShouldDie(), "");
+}
+
+int main(int argc, char** argv) {
+ ::testing::InitGoogleTest(&argc, argv);
+ ::testing::FLAGS_gtest_death_test_style = "fast";
+ return RUN_ALL_TESTS();
+}
+```
+
+## Caveats ##
+
+The _statement_ argument of `ASSERT_EXIT()` can be any valid C++ statement.
+If it leaves the current function via a `return` statement or by throwing an exception,
+the death test is considered to have failed. Some Google Test macros may return
+from the current function (e.g. `ASSERT_TRUE()`), so be sure to avoid them in _statement_.
+
+Since _statement_ runs in the child process, any in-memory side effect (e.g.
+modifying a variable, releasing memory, etc) it causes will _not_ be observable
+in the parent process. In particular, if you release memory in a death test,
+your program will fail the heap check as the parent process will never see the
+memory reclaimed. To solve this problem, you can
+
+ 1. try not to free memory in a death test;
+ 1. free the memory again in the parent process; or
+ 1. do not use the heap checker in your program.
+
+Due to an implementation detail, you cannot place multiple death test
+assertions on the same line; otherwise, compilation will fail with an unobvious
+error message.
+
+Despite the improved thread safety afforded by the "threadsafe" style of death
+test, thread problems such as deadlock are still possible in the presence of
+handlers registered with `pthread_atfork(3)`.
+
+# Using Assertions in Sub-routines #
+
+## Adding Traces to Assertions ##
+
+If a test sub-routine is called from several places, when an assertion
+inside it fails, it can be hard to tell which invocation of the
+sub-routine the failure is from. You can alleviate this problem using
+extra logging or custom failure messages, but that usually clutters up
+your tests. A better solution is to use the `SCOPED_TRACE` macro or
+the `ScopedTrace` utility:
+
+| `SCOPED_TRACE(`_message_`);` | `::testing::ScopedTrace trace(`_"file\_path"_`, `_line\_number_`, `_message_`);` |
+|:-----------------------------|:---------------------------------------------------------------------------------|
+
+where `message` can be anything streamable to `std::ostream`. `SCOPED_TRACE`
+macro will cause the current file name, line number, and the given message to be
+added in every failure message. `ScopedTrace` accepts explicit file name and
+line number in arguments, which is useful for writing test helpers. The effect
+will be undone when the control leaves the current lexical scope.
+
+For example,
+
+```
+10: void Sub1(int n) {
+11: EXPECT_EQ(1, Bar(n));
+12: EXPECT_EQ(2, Bar(n + 1));
+13: }
+14:
+15: TEST(FooTest, Bar) {
+16: {
+17: SCOPED_TRACE("A"); // This trace point will be included in
+18: // every failure in this scope.
+19: Sub1(1);
+20: }
+21: // Now it won't.
+22: Sub1(9);
+23: }
+```
+
+could result in messages like these:
+
+```
+path/to/foo_test.cc:11: Failure
+Value of: Bar(n)
+Expected: 1
+ Actual: 2
+ Trace:
+path/to/foo_test.cc:17: A
+
+path/to/foo_test.cc:12: Failure
+Value of: Bar(n + 1)
+Expected: 2
+ Actual: 3
+```
+
+Without the trace, it would've been difficult to know which invocation
+of `Sub1()` the two failures come from respectively. (You could add an
+extra message to each assertion in `Sub1()` to indicate the value of
+`n`, but that's tedious.)
+
+Some tips on using `SCOPED_TRACE`:
+
+ 1. With a suitable message, it's often enough to use `SCOPED_TRACE` at the beginning of a sub-routine, instead of at each call site.
+ 1. When calling sub-routines inside a loop, make the loop iterator part of the message in `SCOPED_TRACE` such that you can know which iteration the failure is from.
+ 1. Sometimes the line number of the trace point is enough for identifying the particular invocation of a sub-routine. In this case, you don't have to choose a unique message for `SCOPED_TRACE`. You can simply use `""`.
+ 1. You can use `SCOPED_TRACE` in an inner scope when there is one in the outer scope. In this case, all active trace points will be included in the failure messages, in reverse order they are encountered.
+ 1. The trace dump is clickable in Emacs' compilation buffer - hit return on a line number and you'll be taken to that line in the source file!

+
+## Propagating Fatal Failures ##
+
+A common pitfall when using `ASSERT_*` and `FAIL*` is not understanding that
+when they fail they only abort the _current function_, not the entire test. For
+example, the following test will segfault:
+```
+void Subroutine() {
+ // Generates a fatal failure and aborts the current function.
+ ASSERT_EQ(1, 2);
+ // The following won't be executed.
+ ...
+}
+
+TEST(FooTest, Bar) {
+ Subroutine();
+ // The intended behavior is for the fatal failure
+ // in Subroutine() to abort the entire test.
+ // The actual behavior: the function goes on after Subroutine() returns.
+ int* p = NULL;
+ *p = 3; // Segfault!
+}
+```
+
+To alleviate this, gUnit provides three different solutions. You could use
+either exceptions, the `(ASSERT|EXPECT)_NO_FATAL_FAILURE` assertions or the
+`HasFatalFailure()` function. They are described in the following two
+subsections.
+
+#### Asserting on Subroutines with an exception
+
+The following code can turn ASSERT-failure into an exception:
+
+```c++
+class ThrowListener : public testing::EmptyTestEventListener {
+ void OnTestPartResult(const testing::TestPartResult& result) override {
+ if (result.type() == testing::TestPartResult::kFatalFailure) {
+ throw testing::AssertionException(result);
+ }
+ }
+};
+int main(int argc, char** argv) {
+ ...
+ testing::UnitTest::GetInstance()->listeners().Append(new ThrowListener);
+ return RUN_ALL_TESTS();
+}
+```
+
+This listener should be added after other listeners if you have any, otherwise
+they won't see failed `OnTestPartResult`.
+
+### Asserting on Subroutines ###
+
+As shown above, if your test calls a subroutine that has an `ASSERT_*`
+failure in it, the test will continue after the subroutine
+returns. This may not be what you want.
+
+Often people want fatal failures to propagate like exceptions. For
+that Google Test offers the following macros:
+
+| **Fatal assertion** | **Nonfatal assertion** | **Verifies** |
+|:--------------------|:-----------------------|:-------------|
+| `ASSERT_NO_FATAL_FAILURE(`_statement_`);` | `EXPECT_NO_FATAL_FAILURE(`_statement_`);` | _statement_ doesn't generate any new fatal failures in the current thread. |
+
+Only failures in the thread that executes the assertion are checked to
+determine the result of this type of assertions. If _statement_
+creates new threads, failures in these threads are ignored.
+
+Examples:
+
+```
+ASSERT_NO_FATAL_FAILURE(Foo());
+
+int i;
+EXPECT_NO_FATAL_FAILURE({
+ i = Bar();
+});
+```
+
+_Availability:_ Linux, Windows, Mac. Assertions from multiple threads
+are currently not supported.
+
+### Checking for Failures in the Current Test ###
+
+`HasFatalFailure()` in the `::testing::Test` class returns `true` if an
+assertion in the current test has suffered a fatal failure. This
+allows functions to catch fatal failures in a sub-routine and return
+early.
+
+```
+class Test {
+ public:
+ ...
+ static bool HasFatalFailure();
+};
+```
+
+The typical usage, which basically simulates the behavior of a thrown
+exception, is:
+
+```
+TEST(FooTest, Bar) {
+ Subroutine();
+ // Aborts if Subroutine() had a fatal failure.
+ if (HasFatalFailure())
+ return;
+ // The following won't be executed.
+ ...
+}
+```
+
+If `HasFatalFailure()` is used outside of `TEST()` , `TEST_F()` , or a test
+fixture, you must add the `::testing::Test::` prefix, as in:
+
+```
+if (::testing::Test::HasFatalFailure())
+ return;
+```
+
+Similarly, `HasNonfatalFailure()` returns `true` if the current test
+has at least one non-fatal failure, and `HasFailure()` returns `true`
+if the current test has at least one failure of either kind.
+
+_Availability:_ Linux, Windows, Mac. `HasNonfatalFailure()` and
+`HasFailure()` are available since version 1.4.0.
+
+# Logging Additional Information #
+
+In your test code, you can call `RecordProperty("key", value)` to log
+additional information, where `value` can be either a string or an `int`. The _last_ value recorded for a key will be emitted to the XML output
+if you specify one. For example, the test
+
+```
+TEST_F(WidgetUsageTest, MinAndMaxWidgets) {
+ RecordProperty("MaximumWidgets", ComputeMaxUsage());
+ RecordProperty("MinimumWidgets", ComputeMinUsage());
+}
+```
+
+will output XML like this:
+
+```
+...
+ <testcase name="MinAndMaxWidgets" status="run" time="6" classname="WidgetUsageTest"
+ MaximumWidgets="12"
+ MinimumWidgets="9" />
+...
+```
+
+_Note_:
+ * `RecordProperty()` is a static member of the `Test` class. Therefore it needs to be prefixed with `::testing::Test::` if used outside of the `TEST` body and the test fixture class.
+ * `key` must be a valid XML attribute name, and cannot conflict with the ones already used by Google Test (`name`, `status`, `time`, `classname`, `type_param`, and `value_param`).

If it's called outside of a test but between a test case's `SetUpTestCase()` and `TearDownTestCase()` methods, it will be attributed to the XML element for the test case.

+# Sharing Resources Between Tests in the Same Test Case #
+
+
+
+Google Test creates a new test fixture object for each test in order to make
+tests independent and easier to debug. However, sometimes tests use resources
+that are expensive to set up, making the one-copy-per-test model prohibitively
+expensive.
+
+If the tests don't change the resource, there's no harm in them sharing a
+single resource copy. So, in addition to per-test set-up/tear-down, Google Test
+also supports per-test-case set-up/tear-down. To use it:
+
+ 1. In your test fixture class (say `FooTest` ), define as `static` some member variables to hold the shared resources.
+ 1. In the same test fixture class, define a `static void SetUpTestCase()` function (remember not to spell it as **`SetupTestCase`** with a small `u`!) to set up the shared resources and a `static void TearDownTestCase()` function to tear them down.
+
+That's it! Google Test automatically calls `SetUpTestCase()` before running the
+_first test_ in the `FooTest` test case (i.e. before creating the first
+`FooTest` object), and calls `TearDownTestCase()` after running the _last test_
+in it (i.e. after deleting the last `FooTest` object). In between, the tests
+can use the shared resources.
+
+Remember that the test order is undefined, so your code can't depend on a test
+preceding or following another. Also, the tests must either not modify the
+state of any shared resource, or, if they do modify the state, they must
+restore the state to its original value before passing control to the next
+test.
+
+Here's an example of per-test-case set-up and tear-down:
+```
+class FooTest : public ::testing::Test {
+ protected:
+ // Per-test-case set-up.
+ // Called before the first test in this test case.
+ // Can be omitted if not needed.
+ static void SetUpTestCase() {
+ shared_resource_ = new ...;
+ }
+
+ // Per-test-case tear-down.
+ // Called after the last test in this test case.
+ // Can be omitted if not needed.
+ static void TearDownTestCase() {
+ delete shared_resource_;
+ shared_resource_ = NULL;
+ }
+
+ // You can define per-test set-up and tear-down logic as usual.
+ virtual void SetUp() { ... }
+ virtual void TearDown() { ... }
+
+ // Some expensive resource shared by all tests.
+ static T* shared_resource_;
+};
+
+T* FooTest::shared_resource_ = NULL;
+
+TEST_F(FooTest, Test1) {
+ ... you can refer to shared_resource here ...
+}
+TEST_F(FooTest, Test2) {
+ ... you can refer to shared_resource here ...
+}
+```
+
+_Availability:_ Linux, Windows, Mac.
+
+# Global Set-Up and Tear-Down #
+
+Just as you can do set-up and tear-down at the test level and the test case
+level, you can also do it at the test program level. Here's how.
+
+First, you subclass the `::testing::Environment` class to define a test
+environment, which knows how to set-up and tear-down:
+
+```
+class Environment {
+ public:
+ virtual ~Environment() {}
+ // Override this to define how to set up the environment.
+ virtual void SetUp() {}
+ // Override this to define how to tear down the environment.
+ virtual void TearDown() {}
+};
+```
+
+Then, you register an instance of your environment class with Google Test by
+calling the `::testing::AddGlobalTestEnvironment()` function:
+
+```
+Environment* AddGlobalTestEnvironment(Environment* env);
+```
+
+Now, when `RUN_ALL_TESTS()` is called, it first calls the `SetUp()` method of
+the environment object, then runs the tests if there was no fatal failures, and
+finally calls `TearDown()` of the environment object.
+
+It's OK to register multiple environment objects. In this case, their `SetUp()`
+will be called in the order they are registered, and their `TearDown()` will be
+called in the reverse order.
+
+Note that Google Test takes ownership of the registered environment objects.
+Therefore **do not delete them** by yourself.
+
+You should call `AddGlobalTestEnvironment()` before `RUN_ALL_TESTS()` is
+called, probably in `main()`. If you use `gtest_main`, you need to call
+this before `main()` starts for it to take effect. One way to do this is to
+define a global variable like this:
+
+```
+::testing::Environment* const foo_env = ::testing::AddGlobalTestEnvironment(new FooEnvironment);
+```
+
+However, we strongly recommend you to write your own `main()` and call
+`AddGlobalTestEnvironment()` there, as relying on initialization of global
+variables makes the code harder to read and may cause problems when you
+register multiple environments from different translation units and the
+environments have dependencies among them (remember that the compiler doesn't
+guarantee the order in which global variables from different translation units
+are initialized).

+
+
+# Value Parameterized Tests #
+
+_Value-parameterized tests_ allow you to test your code with different
+parameters without writing multiple copies of the same test.
+
+Suppose you write a test for your code and then realize that your code is affected by a presence of a Boolean command line flag.
+
+```
+TEST(MyCodeTest, TestFoo) {
+ // A code to test foo().
+}
+```
+
+Usually people factor their test code into a function with a Boolean parameter in such situations. The function sets the flag, then executes the testing code.
+
+```
+void TestFooHelper(bool flag_value) {
+ flag = flag_value;
+ // A code to test foo().
+}
+
+TEST(MyCodeTest, TestFoo) {
+ TestFooHelper(false);
+ TestFooHelper(true);
+}
+```
+
+But this setup has serious drawbacks. First, when a test assertion fails in your tests, it becomes unclear what value of the parameter caused it to fail. You can stream a clarifying message into your `EXPECT`/`ASSERT` statements, but it you'll have to do it with all of them. Second, you have to add one such helper function per test. What if you have ten tests? Twenty? A hundred?
+
+Value-parameterized tests will let you write your test only once and then easily instantiate and run it with an arbitrary number of parameter values.
+
+Here are some other situations when value-parameterized tests come handy:
+
+ * You want to test different implementations of an OO interface.
+ * You want to test your code over various inputs (a.k.a. data-driven testing). This feature is easy to abuse, so please exercise your good sense when doing it!
+
+## How to Write Value-Parameterized Tests ##
+
+To write value-parameterized tests, first you should define a fixture
+class. It must be derived from both `::testing::Test` and
+`::testing::WithParamInterface<T>` (the latter is a pure interface),
+where `T` is the type of your parameter values. For convenience, you
+can just derive the fixture class from `::testing::TestWithParam<T>`,
+which itself is derived from both `::testing::Test` and
+`::testing::WithParamInterface<T>`. `T` can be any copyable type. If
+it's a raw pointer, you are responsible for managing the lifespan of
+the pointed values.
+
+```
+class FooTest : public ::testing::TestWithParam<const char*> {
+ // You can implement all the usual fixture class members here.
+ // To access the test parameter, call GetParam() from class
+ // TestWithParam<T>.
+};
+
+// Or, when you want to add parameters to a pre-existing fixture class:
+class BaseTest : public ::testing::Test {
+ ...
+};
+class BarTest : public BaseTest,
+ public ::testing::WithParamInterface<const char*> {
+ ...
+};
+```
+
+Then, use the `TEST_P` macro to define as many test patterns using
+this fixture as you want. The `_P` suffix is for "parameterized" or
+"pattern", whichever you prefer to think.
+
+```
+TEST_P(FooTest, DoesBlah) {
+ // Inside a test, access the test parameter with the GetParam() method
+ // of the TestWithParam<T> class:
+ EXPECT_TRUE(foo.Blah(GetParam()));
+ ...
+}
+
+TEST_P(FooTest, HasBlahBlah) {
+ ...
+}
+```
+
+Finally, you can use `INSTANTIATE_TEST_CASE_P` to instantiate the test
+case with any set of parameters you want. Google Test defines a number of
+functions for generating test parameters. They return what we call
+(surprise!) _parameter generators_. Here is a summary of them,
+which are all in the `testing` namespace:
+
+| `Range(begin, end[, step])` | Yields values `{begin, begin+step, begin+step+step, ...}`. The values do not include `end`. `step` defaults to 1. |
+|:----------------------------|:------------------------------------------------------------------------------------------------------------------|
+| `Values(v1, v2, ..., vN)` | Yields values `{v1, v2, ..., vN}`. |
+| `ValuesIn(container)` and `ValuesIn(begin, end)` | Yields values from a C-style array, an STL-style container, or an iterator range `[begin, end)`. `container`, `begin`, and `end` can be expressions whose values are determined at run time. |
+| `Bool()` | Yields sequence `{false, true}`. |
+| `Combine(g1, g2, ..., gN)` | Yields all combinations (the Cartesian product for the math savvy) of the values generated by the `N` generators. This is only available if your system provides the `<tr1/tuple>` header. If you are sure your system does, and Google Test disagrees, you can override it by defining `GTEST_HAS_TR1_TUPLE=1`. See comments in [include/gtest/internal/gtest-port.h](../include/gtest/internal/gtest-port.h) for more information. |
+
+For more details, see the comments at the definitions of these functions in the [source code](../include/gtest/gtest-param-test.h).
+
+The following statement will instantiate tests from the `FooTest` test case
+each with parameter values `"meeny"`, `"miny"`, and `"moe"`.
+
+```
+INSTANTIATE_TEST_CASE_P(InstantiationName,
+ FooTest,
+ ::testing::Values("meeny", "miny", "moe"));
+```
+
+To distinguish different instances of the pattern (yes, you can
+instantiate it more than once), the first argument to
+`INSTANTIATE_TEST_CASE_P` is a prefix that will be added to the actual
+test case name. Remember to pick unique prefixes for different
+instantiations. The tests from the instantiation above will have these
+names:
+
+ * `InstantiationName/FooTest.DoesBlah/0` for `"meeny"`
+ * `InstantiationName/FooTest.DoesBlah/1` for `"miny"`
+ * `InstantiationName/FooTest.DoesBlah/2` for `"moe"`
+ * `InstantiationName/FooTest.HasBlahBlah/0` for `"meeny"`
+ * `InstantiationName/FooTest.HasBlahBlah/1` for `"miny"`
+ * `InstantiationName/FooTest.HasBlahBlah/2` for `"moe"`
+
+You can use these names in [--gtest\_filter](#running-a-subset-of-the-tests).
+
+This statement will instantiate all tests from `FooTest` again, each
+with parameter values `"cat"` and `"dog"`:
+
+```
+const char* pets[] = {"cat", "dog"};
+INSTANTIATE_TEST_CASE_P(AnotherInstantiationName, FooTest,
+ ::testing::ValuesIn(pets));
+```
+
+The tests from the instantiation above will have these names:
+
+ * `AnotherInstantiationName/FooTest.DoesBlah/0` for `"cat"`
+ * `AnotherInstantiationName/FooTest.DoesBlah/1` for `"dog"`
+ * `AnotherInstantiationName/FooTest.HasBlahBlah/0` for `"cat"`
+ * `AnotherInstantiationName/FooTest.HasBlahBlah/1` for `"dog"`
+
+Please note that `INSTANTIATE_TEST_CASE_P` will instantiate _all_
+tests in the given test case, whether their definitions come before or
+_after_ the `INSTANTIATE_TEST_CASE_P` statement.

+
+## Creating Value-Parameterized Abstract Tests ##
+
+In the above, we define and instantiate `FooTest` in the same source
+file. Sometimes you may want to define value-parameterized tests in a
+library and let other people instantiate them later. This pattern is
+known as <i>abstract tests</i>. As an example of its application, when you
+are designing an interface you can write a standard suite of abstract
+tests (perhaps using a factory function as the test parameter) that
+all implementations of the interface are expected to pass. When
+someone implements the interface, they can instantiate your suite to get
+all the interface-conformance tests for free.
+
+To define abstract tests, you should organize your code like this:
+
+ 1. Put the definition of the parameterized test fixture class (e.g. `FooTest`) in a header file, say `foo_param_test.h`. Think of this as _declaring_ your abstract tests.
+ 1. Put the `TEST_P` definitions in `foo_param_test.cc`, which includes `foo_param_test.h`. Think of this as _implementing_ your abstract tests.
+
+Once they are defined, you can instantiate them by including
+`foo_param_test.h`, invoking `INSTANTIATE_TEST_CASE_P()`, and linking
+with `foo_param_test.cc`. You can instantiate the same abstract test
+case multiple times, possibly in different source files.
+
+# Typed Tests #
+
+Suppose you have multiple implementations of the same interface and
+want to make sure that all of them satisfy some common requirements.
+Or, you may have defined several types that are supposed to conform to
+the same "concept" and you want to verify it. In both cases, you want
+the same test logic repeated for different types.
+
+While you can write one `TEST` or `TEST_F` for each type you want to
+test (and you may even factor the test logic into a function template
+that you invoke from the `TEST`), it's tedious and doesn't scale:
+if you want _m_ tests over _n_ types, you'll end up writing _m\*n_
+`TEST`s.
+
+_Typed tests_ allow you to repeat the same test logic over a list of
+types. You only need to write the test logic once, although you must
+know the type list when writing typed tests. Here's how you do it:
+
+First, define a fixture class template. It should be parameterized
+by a type. Remember to derive it from `::testing::Test`:
+
+```
+template <typename T>
+class FooTest : public ::testing::Test {
+ public:
+ ...
+ typedef std::list<T> List;
+ static T shared_;
+ T value_;
+};
+```
+
+Next, associate a list of types with the test case, which will be
+repeated for each type in the list:
+
+```
+typedef ::testing::Types<char, int, unsigned int> MyTypes;
+TYPED_TEST_CASE(FooTest, MyTypes);
+```
+
+The `typedef` is necessary for the `TYPED_TEST_CASE` macro to parse
+correctly. Otherwise the compiler will think that each comma in the
+type list introduces a new macro argument.
+
+Then, use `TYPED_TEST()` instead of `TEST_F()` to define a typed test
+for this test case. You can repeat this as many times as you want:
+
+```
+TYPED_TEST(FooTest, DoesBlah) {
+ // Inside a test, refer to the special name TypeParam to get the type
+ // parameter. Since we are inside a derived class template, C++ requires
+ // us to visit the members of FooTest via 'this'.
+ TypeParam n = this->value_;
+
+ // To visit static members of the fixture, add the 'TestFixture::'
+ // prefix.
+ n += TestFixture::shared_;
+
+ // To refer to typedefs in the fixture, add the 'typename TestFixture::'
+ // prefix. The 'typename' is required to satisfy the compiler.
+ typename TestFixture::List values;
+ values.push_back(n);
+ ...
+}
+
+TYPED_TEST(FooTest, HasPropertyA) { ... }
+```
+
+You can see [`samples/sample6_unittest.cc`](../samples/sample6_unittest.cc) for a complete example.
+
+_Availability:_ Linux, Windows (requires MSVC 8.0 or above), Mac;
+since version 1.1.0.
+
+# Type-Parameterized Tests #
+
+_Type-parameterized tests_ are like typed tests, except that they
+don't require you to know the list of types ahead of time. Instead,
+you can define the test logic first and instantiate it with different
+type lists later. You can even instantiate it more than once in the
+same program.
+
+If you are designing an interface or concept, you can define a suite
+of type-parameterized tests to verify properties that any valid
+implementation of the interface/concept should have. Then, the author
+of each implementation can just instantiate the test suite with his
+type to verify that it conforms to the requirements, without having to
+write similar tests repeatedly. Here's an example:
+
+First, define a fixture class template, as we did with typed tests:
+
+```
+template <typename T>
+class FooTest : public ::testing::Test {
+ ...
+};
+```
+
+Next, declare that you will define a type-parameterized test case:
+
+```
+TYPED_TEST_CASE_P(FooTest);
+```
+
+The `_P` suffix is for "parameterized" or "pattern", whichever you
+prefer to think.
+
+Then, use `TYPED_TEST_P()` to define a type-parameterized test. You
+can repeat this as many times as you want:
+
+```
+TYPED_TEST_P(FooTest, DoesBlah) {
+ // Inside a test, refer to TypeParam to get the type parameter.
+ TypeParam n = 0;
+ ...
+}
+
+TYPED_TEST_P(FooTest, HasPropertyA) { ... }
+```
+
+Now the tricky part: you need to register all test patterns using the
+`REGISTER_TYPED_TEST_CASE_P` macro before you can instantiate them.
+The first argument of the macro is the test case name; the rest are
+the names of the tests in this test case:
+
+```
+REGISTER_TYPED_TEST_CASE_P(FooTest,
+ DoesBlah, HasPropertyA);
+```
+
+Finally, you are free to instantiate the pattern with the types you
+want. If you put the above code in a header file, you can `#include`
+it in multiple C++ source files and instantiate it multiple times.
+
+```
+typedef ::testing::Types<char, int, unsigned int> MyTypes;
+INSTANTIATE_TYPED_TEST_CASE_P(My, FooTest, MyTypes);
+```
+
+To distinguish different instances of the pattern, the first argument
+to the `INSTANTIATE_TYPED_TEST_CASE_P` macro is a prefix that will be
+added to the actual test case name. Remember to pick unique prefixes
+for different instances.
+
+In the special case where the type list contains only one type, you
+can write that type directly without `::testing::Types<...>`, like this:
+
+```
+INSTANTIATE_TYPED_TEST_CASE_P(My, FooTest, int);
+```

+
+# Testing Private Code #
+
+If you change your software's internal implementation, your tests should not
+break as long as the change is not observable by users. Therefore, per the
+_black-box testing principle_, most of the time you should test your code
+through its public interfaces.
+
+If you still find yourself needing to test internal implementation code,
+consider if there's a better design that wouldn't require you to do so. If you
+absolutely have to test non-public interface code though, you can. There are
+two cases to consider:
+
+ * Static functions (_not_ the same as static member functions!) or unnamed namespaces, and
+ * Private or protected class members.
+
+## Static Functions ##
+
+Both static functions and definitions/declarations in an unnamed namespace are
+only visible within the same translation unit. To test them, you can `#include`
+the entire `.cc` file being tested in your `*_test.cc` file. (`#include`ing `.cc`
+files is not a good way to reuse code - you should not do this in production
+code!)
+
+However, a better approach is to move the private code into the
+`foo::internal` namespace, where `foo` is the namespace your project normally
+uses, and put the private declarations in a `*-internal.h` file. Your
+production `.cc` files and your tests are allowed to include this internal
+header, but your clients are not. This way, you can fully test your internal
+implementation without leaking it to your clients.
+
+## Private Class Members ##
+
+Private class members are only accessible from within the class or by friends.
+To access a class' private members, you can declare your test fixture as a
+friend to the class and define accessors in your fixture. Tests using the
+fixture can then access the private members of your production class via the
+accessors in the fixture. Note that even though your fixture is a friend to
+your production class, your tests are not automatically friends to it, as they
+are technically defined in sub-classes of the fixture.
+
+Another way to test private members is to refactor them into an implementation
+class, which is then declared in a `*-internal.h` file. Your clients aren't
+allowed to include this header but your tests can. Such is called the Pimpl
+(Private Implementation) idiom.
+
+Or, you can declare an individual test as a friend of your class by adding this
+line in the class body:
+
+```
+FRIEND_TEST(TestCaseName, TestName);
+```
+
+For example,
+```
+// foo.h
+#include "gtest/gtest_prod.h"
+
+// Defines FRIEND_TEST.
+class Foo {
+ ...
+ private:
+ FRIEND_TEST(FooTest, BarReturnsZeroOnNull);
+ int Bar(void* x);
+};
+
+// foo_test.cc
+...
+TEST(FooTest, BarReturnsZeroOnNull) {
+ Foo foo;
+ EXPECT_EQ(0, foo.Bar(NULL));
+ // Uses Foo's private member Bar().
+}
+```
+
+Pay special attention when your class is defined in a namespace, as you should
+define your test fixtures and tests in the same namespace if you want them to
+be friends of your class. For example, if the code to be tested looks like:
+
+```
+namespace my_namespace {
+
+class Foo {
+ friend class FooTest;
+ FRIEND_TEST(FooTest, Bar);
+ FRIEND_TEST(FooTest, Baz);
+ ...
+ definition of the class Foo
+ ...
+};
+
+} // namespace my_namespace
+```
+
+Your test code should be something like:
+
+```
+namespace my_namespace {
+class FooTest : public ::testing::Test {
+ protected:
+ ...
+};
+
+TEST_F(FooTest, Bar) { ... }
+TEST_F(FooTest, Baz) { ... }
+
+} // namespace my_namespace
+```
+
+# Catching Failures #
+
+If you are building a testing utility on top of Google Test, you'll
+want to test your utility. What framework would you use to test it?
+Google Test, of course.
+
+The challenge is to verify that your testing utility reports failures
+correctly. In frameworks that report a failure by throwing an
+exception, you could catch the exception and assert on it. But Google
+Test doesn't use exceptions, so how do we test that a piece of code
+generates an expected failure?
+
+`"gtest/gtest-spi.h"` contains some constructs to do this. After
+`#include`ing this header, you can use
+
+| `EXPECT_FATAL_FAILURE(`_statement, substring_`);` |
+|:--------------------------------------------------|
+
+to assert that _statement_ generates a fatal (e.g. `ASSERT_*`) failure
+whose message contains the given _substring_, or use
+
+| `EXPECT_NONFATAL_FAILURE(`_statement, substring_`);` |
+|:-----------------------------------------------------|
+
+if you are expecting a non-fatal (e.g. `EXPECT_*`) failure.
+
+For technical reasons, there are some caveats:
+
+ 1. You cannot stream a failure message to either macro.
+ 1. _statement_ in `EXPECT_FATAL_FAILURE()` cannot reference local non-static variables or non-static members of `this` object.
+ 1. _statement_ in `EXPECT_FATAL_FAILURE()` cannot return a value.
+
+_Note:_ Google Test is designed with threads in mind. Once the
+synchronization primitives in `"gtest/internal/gtest-port.h"` have
+been implemented, Google Test will become thread-safe, meaning that
+you can then use assertions in multiple threads concurrently. Before
+that, however, Google Test only supports single-threaded usage. Once
+thread-safe, `EXPECT_FATAL_FAILURE()` and `EXPECT_NONFATAL_FAILURE()`
+will capture failures in the current thread only. If _statement_
+creates new threads, failures in these threads will be ignored. If
+you want to capture failures from all threads instead, you should use
+the following macros:
+
+| `EXPECT_FATAL_FAILURE_ON_ALL_THREADS(`_statement, substring_`);` |
+|:-----------------------------------------------------------------|
+| `EXPECT_NONFATAL_FAILURE_ON_ALL_THREADS(`_statement, substring_`);` |
+
+# Getting the Current Test's Name #
+
+Sometimes a function may need to know the name of the currently running test.
+For example, you may be using the `SetUp()` method of your test fixture to set
+the golden file name based on which test is running. The `::testing::TestInfo`
+class has this information:
+
+```
+namespace testing {
+
+class TestInfo {
+ public:
+ // Returns the test case name and the test name, respectively.
+ //
+ // Do NOT delete or free the return value - it's managed by the
+ // TestInfo class.
+ const char* test_case_name() const;
+ const char* name() const;
+};
+
+} // namespace testing
+```
+
+
+> To obtain a `TestInfo` object for the currently running test, call
+`current_test_info()` on the `UnitTest` singleton object:
+
+```
+// Gets information about the currently running test.
+// Do NOT delete the returned object - it's managed by the UnitTest class.
+const ::testing::TestInfo* const test_info =
+ ::testing::UnitTest::GetInstance()->current_test_info();
+printf("We are in test %s of test case %s.\n",
+ test_info->name(), test_info->test_case_name());
+```
+
+`current_test_info()` returns a null pointer if no test is running. In
+particular, you cannot find the test case name in `SetUpTestCase()`,
+`TearDownTestCase()` (where you know the test case name implicitly), or
+functions called from them.

+
+# Extending Google Test by Handling Test Events #
+
+Google Test provides an <b>event listener API</b> to let you receive
+notifications about the progress of a test program and test
+failures. The events you can listen to include the start and end of
+the test program, a test case, or a test method, among others. You may
+use this API to augment or replace the standard console output,
+replace the XML output, or provide a completely different form of
+output, such as a GUI or a database. You can also use test events as
+checkpoints to implement a resource leak checker, for example.
+
+_Availability:_ Linux, Windows, Mac; since v1.4.0.
+
+## Defining Event Listeners ##
+
+To define a event listener, you subclass either
+[testing::TestEventListener](../include/gtest/gtest.h#L991)
+or [testing::EmptyTestEventListener](../include/gtest/gtest.h#L1044).
+The former is an (abstract) interface, where <i>each pure virtual method<br>
+can be overridden to handle a test event</i> (For example, when a test
+starts, the `OnTestStart()` method will be called.). The latter provides
+an empty implementation of all methods in the interface, such that a
+subclass only needs to override the methods it cares about.
+
+When an event is fired, its context is passed to the handler function
+as an argument. The following argument types are used:
+ * [UnitTest](../include/gtest/gtest.h#L1151) reflects the state of the entire test program,
+ * [TestCase](../include/gtest/gtest.h#L778) has information about a test case, which can contain one or more tests,
+ * [TestInfo](../include/gtest/gtest.h#L644) contains the state of a test, and
+ * [TestPartResult](../include/gtest/gtest-test-part.h#L47) represents the result of a test assertion.
+
+An event handler function can examine the argument it receives to find
+out interesting information about the event and the test program's
+state. Here's an example:
+
+```
+ class MinimalistPrinter : public ::testing::EmptyTestEventListener {
+ // Called before a test starts.
+ virtual void OnTestStart(const ::testing::TestInfo& test_info) {
+ printf("*** Test %s.%s starting.\n",
+ test_info.test_case_name(), test_info.name());
+ }
+
+ // Called after a failed assertion or a SUCCEED() invocation.
+ virtual void OnTestPartResult(
+ const ::testing::TestPartResult& test_part_result) {
+ printf("%s in %s:%d\n%s\n",
+ test_part_result.failed() ? "*** Failure" : "Success",
+ test_part_result.file_name(),
+ test_part_result.line_number(),
+ test_part_result.summary());
+ }
+
+ // Called after a test ends.
+ virtual void OnTestEnd(const ::testing::TestInfo& test_info) {
+ printf("*** Test %s.%s ending.\n",
+ test_info.test_case_name(), test_info.name());
+ }
+ };
+```
+
+## Using Event Listeners ##
+
+To use the event listener you have defined, add an instance of it to
+the Google Test event listener list (represented by class
+[TestEventListeners](../include/gtest/gtest.h#L1064)
+- note the "s" at the end of the name) in your
+`main()` function, before calling `RUN_ALL_TESTS()`:
+```
+int main(int argc, char** argv) {
+ ::testing::InitGoogleTest(&argc, argv);
+ // Gets hold of the event listener list.
+ ::testing::TestEventListeners& listeners =
+ ::testing::UnitTest::GetInstance()->listeners();
+ // Adds a listener to the end. Google Test takes the ownership.
+ listeners.Append(new MinimalistPrinter);
+ return RUN_ALL_TESTS();
+}
+```
+
+There's only one problem: the default test result printer is still in
+effect, so its output will mingle with the output from your minimalist
+printer. To suppress the default printer, just release it from the
+event listener list and delete it. You can do so by adding one line:
+```
+ ...
+ delete listeners.Release(listeners.default_result_printer());
+ listeners.Append(new MinimalistPrinter);
+ return RUN_ALL_TESTS();
+```
+
+Now, sit back and enjoy a completely different output from your
+tests. For more details, you can read this
+[sample](../samples/sample9_unittest.cc).
+
+You may append more than one listener to the list. When an `On*Start()`
+or `OnTestPartResult()` event is fired, the listeners will receive it in
+the order they appear in the list (since new listeners are added to
+the end of the list, the default text printer and the default XML
+generator will receive the event first). An `On*End()` event will be
+received by the listeners in the _reverse_ order. This allows output by
+listeners added later to be framed by output from listeners added
+earlier.
+
+## Generating Failures in Listeners ##
+
+You may use failure-raising macros (`EXPECT_*()`, `ASSERT_*()`,
+`FAIL()`, etc) when processing an event. There are some restrictions:
+
+ 1. You cannot generate any failure in `OnTestPartResult()` (otherwise it will cause `OnTestPartResult()` to be called recursively).
+ 1. A listener that handles `OnTestPartResult()` is not allowed to generate any failure.
+
+When you add listeners to the listener list, you should put listeners
+that handle `OnTestPartResult()` _before_ listeners that can generate
+failures. This ensures that failures generated by the latter are
+attributed to the right test by the former.
+
+We have a sample of failure-raising listener
+[here](../samples/sample10_unittest.cc).
+
+# Running Test Programs: Advanced Options #
+
+Google Test test programs are ordinary executables. Once built, you can run
+them directly and affect their behavior via the following environment variables
+and/or command line flags. For the flags to work, your programs must call
+`::testing::InitGoogleTest()` before calling `RUN_ALL_TESTS()`.
+
+To see a list of supported flags and their usage, please run your test
+program with the `--help` flag. You can also use `-h`, `-?`, or `/?`
+for short. This feature is added in version 1.3.0.
+
+If an option is specified both by an environment variable and by a
+flag, the latter takes precedence. Most of the options can also be
+set/read in code: to access the value of command line flag
+`--gtest_foo`, write `::testing::GTEST_FLAG(foo)`. A common pattern is
+to set the value of a flag before calling `::testing::InitGoogleTest()`
+to change the default value of the flag:
+```
+int main(int argc, char** argv) {
+ // Disables elapsed time by default.
+ ::testing::GTEST_FLAG(print_time) = false;
+
+ // This allows the user to override the flag on the command line.
+ ::testing::InitGoogleTest(&argc, argv);
+
+ return RUN_ALL_TESTS();
+}
+```
+
+## Selecting Tests ##
+
+This section shows various options for choosing which tests to run.
+
+### Listing Test Names ###
+
+Sometimes it is necessary to list the available tests in a program before
+running them so that a filter may be applied if needed. Including the flag
+`--gtest_list_tests` overrides all other flags and lists tests in the following
+format:
+```
+TestCase1.
+ TestName1
+ TestName2
+TestCase2.
+ TestName
+```
+
+None of the tests listed are actually run if the flag is provided. There is no
+corresponding environment variable for this flag.
+
+_Availability:_ Linux, Windows, Mac.
+
+### Running a Subset of the Tests ###
+
+By default, a Google Test program runs all tests the user has defined.
+Sometimes, you want to run only a subset of the tests (e.g. for debugging or
+quickly verifying a change). If you set the `GTEST_FILTER` environment variable
+or the `--gtest_filter` flag to a filter string, Google Test will only run the
+tests whose full names (in the form of `TestCaseName.TestName`) match the
+filter.
+
+The format of a filter is a '`:`'-separated list of wildcard patterns (called
+the positive patterns) optionally followed by a '`-`' and another
+'`:`'-separated pattern list (called the negative patterns). A test matches the
+filter if and only if it matches any of the positive patterns but does not
+match any of the negative patterns.
+
+A pattern may contain `'*'` (matches any string) or `'?'` (matches any single
+character). For convenience, the filter `'*-NegativePatterns'` can be also
+written as `'-NegativePatterns'`.
+
+For example:
+
+ * `./foo_test` Has no flag, and thus runs all its tests.
+ * `./foo_test --gtest_filter=*` Also runs everything, due to the single match-everything `*` value.
+ * `./foo_test --gtest_filter=FooTest.*` Runs everything in test case `FooTest`.
+ * `./foo_test --gtest_filter=*Null*:*Constructor*` Runs any test whose full name contains either `"Null"` or `"Constructor"`.
+ * `./foo_test --gtest_filter=-*DeathTest.*` Runs all non-death tests.
+ * `./foo_test --gtest_filter=FooTest.*-FooTest.Bar` Runs everything in test case `FooTest` except `FooTest.Bar`.
+
+_Availability:_ Linux, Windows, Mac.
+
+### Temporarily Disabling Tests ###
+
+If you have a broken test that you cannot fix right away, you can add the
+`DISABLED_` prefix to its name. This will exclude it from execution. This is
+better than commenting out the code or using `#if 0`, as disabled tests are
+still compiled (and thus won't rot).
+
+If you need to disable all tests in a test case, you can either add `DISABLED_`
+to the front of the name of each test, or alternatively add it to the front of
+the test case name.
+
+For example, the following tests won't be run by Google Test, even though they
+will still be compiled:
+
+```
+// Tests that Foo does Abc.
+TEST(FooTest, DISABLED_DoesAbc) { ... }
+
+class DISABLED_BarTest : public ::testing::Test { ... };
+
+// Tests that Bar does Xyz.
+TEST_F(DISABLED_BarTest, DoesXyz) { ... }
+```
+
+_Note:_ This feature should only be used for temporary pain-relief. You still
+have to fix the disabled tests at a later date. As a reminder, Google Test will
+print a banner warning you if a test program contains any disabled tests.
+
+_Tip:_ You can easily count the number of disabled tests you have
+using `grep`. This number can be used as a metric for improving your
+test quality.
+
+_Availability:_ Linux, Windows, Mac.
+
+### Temporarily Enabling Disabled Tests ###
+
+To include [disabled tests](#temporarily-disabling-tests) in test
+execution, just invoke the test program with the
+`--gtest_also_run_disabled_tests` flag or set the
+`GTEST_ALSO_RUN_DISABLED_TESTS` environment variable to a value other
+than `0`. You can combine this with the
+[--gtest\_filter](#running-a-subset-of-the-tests) flag to further select
+which disabled tests to run.
+
+_Availability:_ Linux, Windows, Mac; since version 1.3.0.
+
+## Repeating the Tests ##
+
+Once in a while you'll run into a test whose result is hit-or-miss. Perhaps it
+will fail only 1% of the time, making it rather hard to reproduce the bug under
+a debugger. This can be a major source of frustration.
+
+The `--gtest_repeat` flag allows you to repeat all (or selected) test methods
+in a program many times. Hopefully, a flaky test will eventually fail and give
+you a chance to debug. Here's how to use it:
+
+| `$ foo_test --gtest_repeat=1000` | Repeat foo\_test 1000 times and don't stop at failures. |
+|:---------------------------------|:--------------------------------------------------------|
+| `$ foo_test --gtest_repeat=-1` | A negative count means repeating forever. |
+| `$ foo_test --gtest_repeat=1000 --gtest_break_on_failure` | Repeat foo\_test 1000 times, stopping at the first failure. This is especially useful when running under a debugger: when the testfails, it will drop into the debugger and you can then inspect variables and stacks. |
+| `$ foo_test --gtest_repeat=1000 --gtest_filter=FooBar` | Repeat the tests whose name matches the filter 1000 times. |
+
+If your test program contains global set-up/tear-down code registered
+using `AddGlobalTestEnvironment()`, it will be repeated in each
+iteration as well, as the flakiness may be in it. You can also specify
+the repeat count by setting the `GTEST_REPEAT` environment variable.
+
+_Availability:_ Linux, Windows, Mac.
+
+## Shuffling the Tests ##
+
+You can specify the `--gtest_shuffle` flag (or set the `GTEST_SHUFFLE`
+environment variable to `1`) to run the tests in a program in a random
+order. This helps to reveal bad dependencies between tests.
+
+By default, Google Test uses a random seed calculated from the current
+time. Therefore you'll get a different order every time. The console
+output includes the random seed value, such that you can reproduce an
+order-related test failure later. To specify the random seed
+explicitly, use the `--gtest_random_seed=SEED` flag (or set the
+`GTEST_RANDOM_SEED` environment variable), where `SEED` is an integer
+between 0 and 99999. The seed value 0 is special: it tells Google Test
+to do the default behavior of calculating the seed from the current
+time.
+
+If you combine this with `--gtest_repeat=N`, Google Test will pick a
+different random seed and re-shuffle the tests in each iteration.
+
+_Availability:_ Linux, Windows, Mac; since v1.4.0.
+
+## Controlling Test Output ##
+
+This section teaches how to tweak the way test results are reported.
+
+### Colored Terminal Output ###
+
+Google Test can use colors in its terminal output to make it easier to spot
+the separation between tests, and whether tests passed.
+
+You can set the GTEST\_COLOR environment variable or set the `--gtest_color`
+command line flag to `yes`, `no`, or `auto` (the default) to enable colors,
+disable colors, or let Google Test decide. When the value is `auto`, Google
+Test will use colors if and only if the output goes to a terminal and (on
+non-Windows platforms) the `TERM` environment variable is set to `xterm` or
+`xterm-color`.
+
+_Availability:_ Linux, Windows, Mac.
+
+### Suppressing the Elapsed Time ###
+
+By default, Google Test prints the time it takes to run each test. To
+suppress that, run the test program with the `--gtest_print_time=0`
+command line flag. Setting the `GTEST_PRINT_TIME` environment
+variable to `0` has the same effect.
+
+_Availability:_ Linux, Windows, Mac. (In Google Test 1.3.0 and lower,
+the default behavior is that the elapsed time is **not** printed.)
+
+**Availability**: Linux, Windows, Mac.
+
+#### Suppressing UTF-8 Text Output
+
+In case of assertion failures, gUnit prints expected and actual values of type
+`string` both as hex-encoded strings as well as in readable UTF-8 text if they
+contain valid non-ASCII UTF-8 characters. If you want to suppress the UTF-8 text
+because, for example, you don't have an UTF-8 compatible output medium, run the
+test program with `--gunit_print_utf8=0` or set the `GUNIT_PRINT_UTF8`
+environment variable to `0`.
+
+### Generating an XML Report ###
+
+Google Test can emit a detailed XML report to a file in addition to its normal
+textual output. The report contains the duration of each test, and thus can
+help you identify slow tests.
+
+To generate the XML report, set the `GTEST_OUTPUT` environment variable or the
+`--gtest_output` flag to the string `"xml:_path_to_output_file_"`, which will
+create the file at the given location. You can also just use the string
+`"xml"`, in which case the output can be found in the `test_detail.xml` file in
+the current directory.
+
+If you specify a directory (for example, `"xml:output/directory/"` on Linux or
+`"xml:output\directory\"` on Windows), Google Test will create the XML file in
+that directory, named after the test executable (e.g. `foo_test.xml` for test
+program `foo_test` or `foo_test.exe`). If the file already exists (perhaps left
+over from a previous run), Google Test will pick a different name (e.g.
+`foo_test_1.xml`) to avoid overwriting it.
+
+The report uses the format described here. It is based on the
+`junitreport` Ant task and can be parsed by popular continuous build
+systems like [Hudson](https://hudson.dev.java.net/). Since that format
+was originally intended for Java, a little interpretation is required
+to make it apply to Google Test tests, as shown here:
+
+```
+<testsuites name="AllTests" ...>
+ <testsuite name="test_case_name" ...>
+ <testcase name="test_name" ...>
+ <failure message="..."/>
+ <failure message="..."/>
+ <failure message="..."/>
+ </testcase>
+ </testsuite>
+</testsuites>
+```
+
+ * The root `<testsuites>` element corresponds to the entire test program.
+ * `<testsuite>` elements correspond to Google Test test cases.
+ * `<testcase>` elements correspond to Google Test test functions.
+
+For instance, the following program
+
+```
+TEST(MathTest, Addition) { ... }
+TEST(MathTest, Subtraction) { ... }
+TEST(LogicTest, NonContradiction) { ... }
+```
+
+could generate this report:
+
+```
+<?xml version="1.0" encoding="UTF-8"?>
+<testsuites tests="3" failures="1" errors="0" time="35" name="AllTests">
+ <testsuite name="MathTest" tests="2" failures="1" errors="0" time="15">
+ <testcase name="Addition" status="run" time="7" classname="">
+ <failure message="Value of: add(1, 1)
 Actual: 3
Expected: 2" type=""/>
+ <failure message="Value of: add(1, -1)
 Actual: 1
Expected: 0" type=""/>
+ </testcase>
+ <testcase name="Subtraction" status="run" time="5" classname="">
+ </testcase>
+ </testsuite>
+ <testsuite name="LogicTest" tests="1" failures="0" errors="0" time="5">
+ <testcase name="NonContradiction" status="run" time="5" classname="">
+ </testcase>
+ </testsuite>
+</testsuites>
+```
+
+Things to note:
+
+ * The `tests` attribute of a `<testsuites>` or `<testsuite>` element tells how many test functions the Google Test program or test case contains, while the `failures` attribute tells how many of them failed.
+ * The `time` attribute expresses the duration of the test, test case, or entire test program in milliseconds.
+ * Each `<failure>` element corresponds to a single failed Google Test assertion.
+ * Some JUnit concepts don't apply to Google Test, yet we have to conform to the DTD. Therefore you'll see some dummy elements and attributes in the report. You can safely ignore these parts.
+
+_Availability:_ Linux, Windows, Mac.
+
+#### Generating an JSON Report {#JsonReport}
+
+gUnit can also emit a JSON report as an alternative format to XML. To generate
+the JSON report, set the `GUNIT_OUTPUT` environment variable or the
+`--gunit_output` flag to the string `"json:path_to_output_file"`, which will
+create the file at the given location. You can also just use the string
+`"json"`, in which case the output can be found in the `test_detail.json` file
+in the current directory.
+
+The report format conforms to the following JSON Schema:
+
+```json
+{
+ "$schema": "http://json-schema.org/schema#",
+ "type": "object",
+ "definitions": {
+ "TestCase": {

+
+The report uses the format that conforms to the following Proto3 using the
+[JSON encoding](https://developers.google.com/protocol-buffers/docs/proto3#json):

+
+## Controlling How Failures Are Reported ##
+
+### Turning Assertion Failures into Break-Points ###
+
+When running test programs under a debugger, it's very convenient if the
+debugger can catch an assertion failure and automatically drop into interactive
+mode. Google Test's _break-on-failure_ mode supports this behavior.
+
+To enable it, set the `GTEST_BREAK_ON_FAILURE` environment variable to a value
+other than `0` . Alternatively, you can use the `--gtest_break_on_failure`
+command line flag.
+
+_Availability:_ Linux, Windows, Mac.
+
+### Disabling Catching Test-Thrown Exceptions ###
+
+Google Test can be used either with or without exceptions enabled. If
+a test throws a C++ exception or (on Windows) a structured exception
+(SEH), by default Google Test catches it, reports it as a test
+failure, and continues with the next test method. This maximizes the
+coverage of a test run. Also, on Windows an uncaught exception will
+cause a pop-up window, so catching the exceptions allows you to run
+the tests automatically.
+
+When debugging the test failures, however, you may instead want the
+exceptions to be handled by the debugger, such that you can examine
+the call stack when an exception is thrown. To achieve that, set the
+`GTEST_CATCH_EXCEPTIONS` environment variable to `0`, or use the
+`--gtest_catch_exceptions=0` flag when running the tests.
+
+**Availability**: Linux, Windows, Mac.
+
+### Letting Another Testing Framework Drive ###
+
+If you work on a project that has already been using another testing
+framework and is not ready to completely switch to Google Test yet,
+you can get much of Google Test's benefit by using its assertions in
+your existing tests. Just change your `main()` function to look
+like:
+
+```
+#include "gtest/gtest.h"
+
+int main(int argc, char** argv) {
+ ::testing::GTEST_FLAG(throw_on_failure) = true;
+ // Important: Google Test must be initialized.
+ ::testing::InitGoogleTest(&argc, argv);
+
+ ... whatever your existing testing framework requires ...
+}
+```
+
+With that, you can use Google Test assertions in addition to the
+native assertions your testing framework provides, for example:
+
+```
+void TestFooDoesBar() {
+ Foo foo;
+ EXPECT_LE(foo.Bar(1), 100); // A Google Test assertion.
+ CPPUNIT_ASSERT(foo.IsEmpty()); // A native assertion.
+}
+```
+
+If a Google Test assertion fails, it will print an error message and
+throw an exception, which will be treated as a failure by your host
+testing framework. If you compile your code with exceptions disabled,
+a failed Google Test assertion will instead exit your program with a
+non-zero code, which will also signal a test failure to your test
+runner.
+
+If you don't write `::testing::GTEST_FLAG(throw_on_failure) = true;` in
+your `main()`, you can alternatively enable this feature by specifying
+the `--gtest_throw_on_failure` flag on the command-line or setting the
+`GTEST_THROW_ON_FAILURE` environment variable to a non-zero value.
+
+Death tests are _not_ supported when other test framework is used to organize tests.
+
+_Availability:_ Linux, Windows, Mac; since v1.3.0.
+
+## Distributing Test Functions to Multiple Machines ##
+
+If you have more than one machine you can use to run a test program,
+you might want to run the test functions in parallel and get the
+result faster. We call this technique _sharding_, where each machine
+is called a _shard_.
+
+Google Test is compatible with test sharding. To take advantage of
+this feature, your test runner (not part of Google Test) needs to do
+the following:
+
+ 1. Allocate a number of machines (shards) to run the tests.
+ 1. On each shard, set the `GTEST_TOTAL_SHARDS` environment variable to the total number of shards. It must be the same for all shards.
+ 1. On each shard, set the `GTEST_SHARD_INDEX` environment variable to the index of the shard. Different shards must be assigned different indices, which must be in the range `[0, GTEST_TOTAL_SHARDS - 1]`.
+ 1. Run the same test program on all shards. When Google Test sees the above two environment variables, it will select a subset of the test functions to run. Across all shards, each test function in the program will be run exactly once.
+ 1. Wait for all shards to finish, then collect and report the results.
+
+Your project may have tests that were written without Google Test and
+thus don't understand this protocol. In order for your test runner to
+figure out which test supports sharding, it can set the environment
+variable `GTEST_SHARD_STATUS_FILE` to a non-existent file path. If a
+test program supports sharding, it will create this file to
+acknowledge the fact (the actual contents of the file are not
+important at this time; although we may stick some useful information
+in it in the future.); otherwise it will not create it.
+
+Here's an example to make it clear. Suppose you have a test program
+`foo_test` that contains the following 5 test functions:
+```
+TEST(A, V)
+TEST(A, W)
+TEST(B, X)
+TEST(B, Y)
+TEST(B, Z)
+```
+and you have 3 machines at your disposal. To run the test functions in
+parallel, you would set `GTEST_TOTAL_SHARDS` to 3 on all machines, and
+set `GTEST_SHARD_INDEX` to 0, 1, and 2 on the machines respectively.
+Then you would run the same `foo_test` on each machine.
+
+Google Test reserves the right to change how the work is distributed
+across the shards, but here's one possible scenario:
+
+ * Machine #0 runs `A.V` and `B.X`.
+ * Machine #1 runs `A.W` and `B.Y`.
+ * Machine #2 runs `B.Z`.
+
+_Availability:_ Linux, Windows, Mac; since version 1.3.0.
+
+# Fusing Google Test Source Files #
+
+Google Test's implementation consists of ~30 files (excluding its own
+tests). Sometimes you may want them to be packaged up in two files (a
+`.h` and a `.cc`) instead, such that you can easily copy them to a new
+machine and start hacking there. For this we provide an experimental
+Python script `fuse_gtest_files.py` in the `scripts/` directory (since release 1.3.0).
+Assuming you have Python 2.4 or above installed on your machine, just
+go to that directory and run
+```
+python fuse_gtest_files.py OUTPUT_DIR
+```
+
+and you should see an `OUTPUT_DIR` directory being created with files
+`gtest/gtest.h` and `gtest/gtest-all.cc` in it. These files contain
+everything you need to use Google Test. Just copy them to anywhere
+you want and you are ready to write tests. You can use the
+[scripts/test/Makefile](../scripts/test/Makefile)
+file as an example on how to compile your tests against them.

+Congratulations! You've now learned more advanced Google Test tools and are
+ready to tackle more complex testing tasks. If you want to dive even deeper, you

+
+## Why should I use Google Test instead of my favorite C++ testing framework? ##
+
+First, let us say clearly that we don't want to get into the debate of
+which C++ testing framework is **the best**. There exist many fine
+frameworks for writing C++ tests, and we have tremendous respect for
+the developers and users of them. We don't think there is (or will
+be) a single best framework - you have to pick the right tool for the
+particular task you are tackling.
+
+We created Google Test because we couldn't find the right combination
+of features and conveniences in an existing framework to satisfy _our_
+needs. The following is a list of things that _we_ like about Google
+Test. We don't claim them to be unique to Google Test - rather, the
+combination of them makes Google Test the choice for us. We hope this
+list can help you decide whether it is for you too.
+
+ * Google Test is designed to be portable: it doesn't require exceptions or RTTI; it works around various bugs in various compilers and environments; etc. As a result, it works on Linux, Mac OS X, Windows and several embedded operating systems.
+ * Nonfatal assertions (`EXPECT_*`) have proven to be great time savers, as they allow a test to report multiple failures in a single edit-compile-test cycle.
+ * It's easy to write assertions that generate informative messages: you just use the stream syntax to append any additional information, e.g. `ASSERT_EQ(5, Foo(i)) << " where i = " << i;`. It doesn't require a new set of macros or special functions.
+ * Google Test automatically detects your tests and doesn't require you to enumerate them in order to run them.
+ * Death tests are pretty handy for ensuring that your asserts in production code are triggered by the right conditions.
+ * `SCOPED_TRACE` helps you understand the context of an assertion failure when it comes from inside a sub-routine or loop.
+ * You can decide which tests to run using name patterns. This saves time when you want to quickly reproduce a test failure.
+ * Google Test can generate XML test result reports that can be parsed by popular continuous build system like Hudson.
+ * Simple things are easy in Google Test, while hard things are possible: in addition to advanced features like [global test environments](AdvancedGuide.md#global-set-up-and-tear-down) and tests parameterized by [values](AdvancedGuide.md#value-parameterized-tests) or [types](docs/AdvancedGuide.md#typed-tests), Google Test supports various ways for the user to extend the framework -- if Google Test doesn't do something out of the box, chances are that a user can implement the feature using Google Test's public API, without changing Google Test itself. In particular, you can:
+ * expand your testing vocabulary by defining [custom predicates](AdvancedGuide.md#predicate-assertions-for-better-error-messages),
+ * teach Google Test how to [print your types](AdvancedGuide.md#teaching-google-test-how-to-print-your-values),
+ * define your own testing macros or utilities and verify them using Google Test's [Service Provider Interface](AdvancedGuide.md#catching-failures), and
+ * reflect on the test cases or change the test output format by intercepting the [test events](AdvancedGuide.md#extending-google-test-by-handling-test-events).
+
+## I'm getting warnings when compiling Google Test. Would you fix them? ##
+
+We strive to minimize compiler warnings Google Test generates. Before releasing a new version, we test to make sure that it doesn't generate warnings when compiled using its CMake script on Windows, Linux, and Mac OS.
+
+Unfortunately, this doesn't mean you are guaranteed to see no warnings when compiling Google Test in your environment:
+
+ * You may be using a different compiler as we use, or a different version of the same compiler. We cannot possibly test for all compilers.
+ * You may be compiling on a different platform as we do.
+ * Your project may be using different compiler flags as we do.
+
+It is not always possible to make Google Test warning-free for everyone. Or, it may not be desirable if the warning is rarely enabled and fixing the violations makes the code more complex.
+
+If you see warnings when compiling Google Test, we suggest that you use the `-isystem` flag (assuming your are using GCC) to mark Google Test headers as system headers. That'll suppress warnings from Google Test headers.
+
+## Why should not test case names and test names contain underscore? ##
+
+Underscore (`_`) is special, as C++ reserves the following to be used by
+the compiler and the standard library:
+
+ 1. any identifier that starts with an `_` followed by an upper-case letter, and
+ 1. any identifier that contains two consecutive underscores (i.e. `__`) _anywhere_ in its name.
+
+User code is _prohibited_ from using such identifiers.
+
+Now let's look at what this means for `TEST` and `TEST_F`.
+
+Currently `TEST(TestCaseName, TestName)` generates a class named
+`TestCaseName_TestName_Test`. What happens if `TestCaseName` or `TestName`
+contains `_`?
+
+ 1. If `TestCaseName` starts with an `_` followed by an upper-case letter (say, `_Foo`), we end up with `_Foo_TestName_Test`, which is reserved and thus invalid.
+ 1. If `TestCaseName` ends with an `_` (say, `Foo_`), we get `Foo__TestName_Test`, which is invalid.
+ 1. If `TestName` starts with an `_` (say, `_Bar`), we get `TestCaseName__Bar_Test`, which is invalid.
+ 1. If `TestName` ends with an `_` (say, `Bar_`), we get `TestCaseName_Bar__Test`, which is invalid.
+
+So clearly `TestCaseName` and `TestName` cannot start or end with `_`
+(Actually, `TestCaseName` can start with `_` -- as long as the `_` isn't
+followed by an upper-case letter. But that's getting complicated. So
+for simplicity we just say that it cannot start with `_`.).
+
+It may seem fine for `TestCaseName` and `TestName` to contain `_` in the
+middle. However, consider this:
+``` cpp
+TEST(Time, Flies_Like_An_Arrow) { ... }
+TEST(Time_Flies, Like_An_Arrow) { ... }
+```
+
+Now, the two `TEST`s will both generate the same class
+(`Time_Files_Like_An_Arrow_Test`). That's not good.
+
+So for simplicity, we just ask the users to avoid `_` in `TestCaseName`
+and `TestName`. The rule is more constraining than necessary, but it's
+simple and easy to remember. It also gives Google Test some wiggle
+room in case its implementation needs to change in the future.
+
+If you violate the rule, there may not be immediately consequences,
+but your test may (just may) break with a new compiler (or a new
+version of the compiler you are using) or with a new version of Google
+Test. Therefore it's best to follow the rule.
+
+## Why is it not recommended to install a pre-compiled copy of Google Test (for example, into /usr/local)? ##
+
+In the early days, we said that you could install
+compiled Google Test libraries on `*`nix systems using `make install`.
+Then every user of your machine can write tests without
+recompiling Google Test.
+
+This seemed like a good idea, but it has a
+got-cha: every user needs to compile their tests using the _same_ compiler
+flags used to compile the installed Google Test libraries; otherwise
+they may run into undefined behaviors (i.e. the tests can behave
+strangely and may even crash for no obvious reasons).
+
+Why? Because C++ has this thing called the One-Definition Rule: if
+two C++ source files contain different definitions of the same
+class/function/variable, and you link them together, you violate the
+rule. The linker may or may not catch the error (in many cases it's
+not required by the C++ standard to catch the violation). If it
+doesn't, you get strange run-time behaviors that are unexpected and
+hard to debug.
+
+If you compile Google Test and your test code using different compiler
+flags, they may see different definitions of the same
+class/function/variable (e.g. due to the use of `#if` in Google Test).
+Therefore, for your sanity, we recommend to avoid installing pre-compiled
+Google Test libraries. Instead, each project should compile
+Google Test itself such that it can be sure that the same flags are
+used for both Google Test and the tests.
+
+## How do I generate 64-bit binaries on Windows (using Visual Studio 2008)? ##
+
+(Answered by Trevor Robinson)
+
+Load the supplied Visual Studio solution file, either `msvc\gtest-md.sln` or
+`msvc\gtest.sln`. Go through the migration wizard to migrate the
+solution and project files to Visual Studio 2008. Select
+`Configuration Manager...` from the `Build` menu. Select `<New...>` from
+the `Active solution platform` dropdown. Select `x64` from the new
+platform dropdown, leave `Copy settings from` set to `Win32` and
+`Create new project platforms` checked, then click `OK`. You now have
+`Win32` and `x64` platform configurations, selectable from the
+`Standard` toolbar, which allow you to toggle between building 32-bit or
+64-bit binaries (or both at once using Batch Build).
+
+In order to prevent build output files from overwriting one another,
+you'll need to change the `Intermediate Directory` settings for the
+newly created platform configuration across all the projects. To do
+this, multi-select (e.g. using shift-click) all projects (but not the
+solution) in the `Solution Explorer`. Right-click one of them and
+select `Properties`. In the left pane, select `Configuration Properties`,
+and from the `Configuration` dropdown, select `All Configurations`.
+Make sure the selected platform is `x64`. For the
+`Intermediate Directory` setting, change the value from
+`$(PlatformName)\$(ConfigurationName)` to
+`$(OutDir)\$(ProjectName)`. Click `OK` and then build the
+solution. When the build is complete, the 64-bit binaries will be in
+the `msvc\x64\Debug` directory.
+
+## Can I use Google Test on MinGW? ##
+
+We haven't tested this ourselves, but Per Abrahamsen reported that he
+was able to compile and install Google Test successfully when using
+MinGW from Cygwin. You'll need to configure it with:
+
+`PATH/TO/configure CC="gcc -mno-cygwin" CXX="g++ -mno-cygwin"`
+
+You should be able to replace the `-mno-cygwin` option with direct links
+to the real MinGW binaries, but we haven't tried that.
+
+Caveats:
+
+ * There are many warnings when compiling.
+ * `make check` will produce some errors as not all tests for Google Test itself are compatible with MinGW.
+
+We also have reports on successful cross compilation of Google Test
+MinGW binaries on Linux using
+[these instructions](http://wiki.wxwidgets.org/Cross-Compiling_Under_Linux#Cross-compiling_under_Linux_for_MS_Windows)
+on the WxWidgets site.
+
+Please contact `googletestframework@googlegroups.com` if you are
+interested in improving the support for MinGW.
+
+## Why does Google Test support EXPECT\_EQ(NULL, ptr) and ASSERT\_EQ(NULL, ptr) but not EXPECT\_NE(NULL, ptr) and ASSERT\_NE(NULL, ptr)? ##
+
+Due to some peculiarity of C++, it requires some non-trivial template
+meta programming tricks to support using `NULL` as an argument of the
+`EXPECT_XX()` and `ASSERT_XX()` macros. Therefore we only do it where
+it's most needed (otherwise we make the implementation of Google Test
+harder to maintain and more error-prone than necessary).
+
+The `EXPECT_EQ()` macro takes the _expected_ value as its first
+argument and the _actual_ value as the second. It's reasonable that
+someone wants to write `EXPECT_EQ(NULL, some_expression)`, and this
+indeed was requested several times. Therefore we implemented it.
+
+The need for `EXPECT_NE(NULL, ptr)` isn't nearly as strong. When the
+assertion fails, you already know that `ptr` must be `NULL`, so it
+doesn't add any information to print ptr in this case. That means
+`EXPECT_TRUE(ptr != NULL)` works just as well.
+
+If we were to support `EXPECT_NE(NULL, ptr)`, for consistency we'll
+have to support `EXPECT_NE(ptr, NULL)` as well, as unlike `EXPECT_EQ`,
+we don't have a convention on the order of the two arguments for
+`EXPECT_NE`. This means using the template meta programming tricks
+twice in the implementation, making it even harder to understand and
+maintain. We believe the benefit doesn't justify the cost.
+
+Finally, with the growth of Google Mock's [matcher](../../googlemock/docs/CookBook.md#using-matchers-in-google-test-assertions) library, we are
+encouraging people to use the unified `EXPECT_THAT(value, matcher)`
+syntax more often in tests. One significant advantage of the matcher
+approach is that matchers can be easily combined to form new matchers,
+while the `EXPECT_NE`, etc, macros cannot be easily
+combined. Therefore we want to invest more in the matchers than in the
+`EXPECT_XX()` macros.
+
+## Does Google Test support running tests in parallel? ##
+
+Test runners tend to be tightly coupled with the build/test
+environment, and Google Test doesn't try to solve the problem of
+running tests in parallel. Instead, we tried to make Google Test work
+nicely with test runners. For example, Google Test's XML report
+contains the time spent on each test, and its `gtest_list_tests` and
+`gtest_filter` flags can be used for splitting the execution of test
+methods into multiple processes. These functionalities can help the
+test runner run the tests in parallel.
+
+## Why don't Google Test run the tests in different threads to speed things up? ##
+
+It's difficult to write thread-safe code. Most tests are not written
+with thread-safety in mind, and thus may not work correctly in a
+multi-threaded setting.
+
+If you think about it, it's already hard to make your code work when
+you know what other threads are doing. It's much harder, and
+sometimes even impossible, to make your code work when you don't know
+what other threads are doing (remember that test methods can be added,
+deleted, or modified after your test was written). If you want to run
+the tests in parallel, you'd better run them in different processes.
+
+## Why aren't Google Test assertions implemented using exceptions? ##
+
+Our original motivation was to be able to use Google Test in projects
+that disable exceptions. Later we realized some additional benefits
+of this approach:
+
+ 1. Throwing in a destructor is undefined behavior in C++. Not using exceptions means Google Test's assertions are safe to use in destructors.
+ 1. The `EXPECT_*` family of macros will continue even after a failure, allowing multiple failures in a `TEST` to be reported in a single run. This is a popular feature, as in C++ the edit-compile-test cycle is usually quite long and being able to fixing more than one thing at a time is a blessing.
+ 1. If assertions are implemented using exceptions, a test may falsely ignore a failure if it's caught by user code:
+``` cpp
+try { ... ASSERT_TRUE(...) ... }
+catch (...) { ... }
+```
+The above code will pass even if the `ASSERT_TRUE` throws. While it's unlikely for someone to write this in a test, it's possible to run into this pattern when you write assertions in callbacks that are called by the code under test.
+
+The downside of not using exceptions is that `ASSERT_*` (implemented
+using `return`) will only abort the current function, not the current
+`TEST`.
+
+## Why do we use two different macros for tests with and without fixtures? ##
+
+Unfortunately, C++'s macro system doesn't allow us to use the same
+macro for both cases. One possibility is to provide only one macro
+for tests with fixtures, and require the user to define an empty
+fixture sometimes:
+
+``` cpp
+class FooTest : public ::testing::Test {};
+
+TEST_F(FooTest, DoesThis) { ... }
+```
+or
+``` cpp
+typedef ::testing::Test FooTest;
+
+TEST_F(FooTest, DoesThat) { ... }
+```
+
+Yet, many people think this is one line too many. :-) Our goal was to
+make it really easy to write tests, so we tried to make simple tests
+trivial to create. That means using a separate macro for such tests.
+
+We think neither approach is ideal, yet either of them is reasonable.
+In the end, it probably doesn't matter much either way.
+
+## Why don't we use structs as test fixtures? ##
+
+We like to use structs only when representing passive data. This
+distinction between structs and classes is good for documenting the
+intent of the code's author. Since test fixtures have logic like
+`SetUp()` and `TearDown()`, they are better defined as classes.
+
+## Why are death tests implemented as assertions instead of using a test runner? ##
+
+Our goal was to make death tests as convenient for a user as C++
+possibly allows. In particular:
+
+ * The runner-style requires to split the information into two pieces: the definition of the death test itself, and the specification for the runner on how to run the death test and what to expect. The death test would be written in C++, while the runner spec may or may not be. A user needs to carefully keep the two in sync. `ASSERT_DEATH(statement, expected_message)` specifies all necessary information in one place, in one language, without boilerplate code. It is very declarative.
+ * `ASSERT_DEATH` has a similar syntax and error-reporting semantics as other Google Test assertions, and thus is easy to learn.
+ * `ASSERT_DEATH` can be mixed with other assertions and other logic at your will. You are not limited to one death test per test method. For example, you can write something like:
+``` cpp
+ if (FooCondition()) {
+ ASSERT_DEATH(Bar(), "blah");
+ } else {
+ ASSERT_EQ(5, Bar());
+ }
+```
+If you prefer one death test per test method, you can write your tests in that style too, but we don't want to impose that on the users. The fewer artificial limitations the better.
+ * `ASSERT_DEATH` can reference local variables in the current function, and you can decide how many death tests you want based on run-time information. For example,
+``` cpp
+ const int count = GetCount(); // Only known at run time.
+ for (int i = 1; i <= count; i++) {
+ ASSERT_DEATH({
+ double* buffer = new double[i];
+ ... initializes buffer ...
+ Foo(buffer, i)
+ }, "blah blah");
+ }
+```
+The runner-based approach tends to be more static and less flexible, or requires more user effort to get this kind of flexibility.
+
+Another interesting thing about `ASSERT_DEATH` is that it calls `fork()`
+to create a child process to run the death test. This is lightening
+fast, as `fork()` uses copy-on-write pages and incurs almost zero
+overhead, and the child process starts from the user-supplied
+statement directly, skipping all global and local initialization and
+any code leading to the given statement. If you launch the child
+process from scratch, it can take seconds just to load everything and
+start running if the test links to many libraries dynamically.
+
+## My death test modifies some state, but the change seems lost after the death test finishes. Why? ##
+
+Death tests (`EXPECT_DEATH`, etc) are executed in a sub-process s.t. the
+expected crash won't kill the test program (i.e. the parent process). As a
+result, any in-memory side effects they incur are observable in their
+respective sub-processes, but not in the parent process. You can think of them
+as running in a parallel universe, more or less.
+
+## The compiler complains about "undefined references" to some static const member variables, but I did define them in the class body. What's wrong? ##
+
+If your class has a static data member:
+
+``` cpp
+// foo.h
+class Foo {
+ ...
+ static const int kBar = 100;
+};
+```
+
+You also need to define it _outside_ of the class body in `foo.cc`:
+
+``` cpp
+const int Foo::kBar; // No initializer here.
+```
+
+Otherwise your code is **invalid C++**, and may break in unexpected ways. In
+particular, using it in Google Test comparison assertions (`EXPECT_EQ`, etc)
+will generate an "undefined reference" linker error.
+
+## I have an interface that has several implementations. Can I write a set of tests once and repeat them over all the implementations? ##
+
+Google Test doesn't yet have good support for this kind of tests, or
+data-driven tests in general. We hope to be able to make improvements in this
+area soon.
+
+## Can I derive a test fixture from another? ##
+
+Yes.
+
+Each test fixture has a corresponding and same named test case. This means only
+one test case can use a particular fixture. Sometimes, however, multiple test
+cases may want to use the same or slightly different fixtures. For example, you
+may want to make sure that all of a GUI library's test cases don't leak
+important system resources like fonts and brushes.
+
+In Google Test, you share a fixture among test cases by putting the shared
+logic in a base test fixture, then deriving from that base a separate fixture
+for each test case that wants to use this common logic. You then use `TEST_F()`
+to write tests using each derived fixture.
+
+Typically, your code looks like this:
+
+``` cpp
+// Defines a base test fixture.
+class BaseTest : public ::testing::Test {
+ protected:
+ ...
+};
+
+// Derives a fixture FooTest from BaseTest.
+class FooTest : public BaseTest {
+ protected:
+ virtual void SetUp() {
+ BaseTest::SetUp(); // Sets up the base fixture first.
+ ... additional set-up work ...
+ }
+ virtual void TearDown() {
+ ... clean-up work for FooTest ...
+ BaseTest::TearDown(); // Remember to tear down the base fixture
+ // after cleaning up FooTest!
+ }
+ ... functions and variables for FooTest ...
+};
+
+// Tests that use the fixture FooTest.
+TEST_F(FooTest, Bar) { ... }
+TEST_F(FooTest, Baz) { ... }
+
+... additional fixtures derived from BaseTest ...
+```
+
+If necessary, you can continue to derive test fixtures from a derived fixture.
+Google Test has no limit on how deep the hierarchy can be.
+
+For a complete example using derived test fixtures, see
+[sample5](../samples/sample5_unittest.cc).
+
+## My compiler complains "void value not ignored as it ought to be." What does this mean? ##
+
+You're probably using an `ASSERT_*()` in a function that doesn't return `void`.
+`ASSERT_*()` can only be used in `void` functions.
+
+## My death test hangs (or seg-faults). How do I fix it? ##
+
+In Google Test, death tests are run in a child process and the way they work is
+delicate. To write death tests you really need to understand how they work.
+Please make sure you have read this.
+
+In particular, death tests don't like having multiple threads in the parent
+process. So the first thing you can try is to eliminate creating threads
+outside of `EXPECT_DEATH()`.
+
+Sometimes this is impossible as some library you must use may be creating
+threads before `main()` is even reached. In this case, you can try to minimize
+the chance of conflicts by either moving as many activities as possible inside
+`EXPECT_DEATH()` (in the extreme case, you want to move everything inside), or
+leaving as few things as possible in it. Also, you can try to set the death
+test style to `"threadsafe"`, which is safer but slower, and see if it helps.
+
+If you go with thread-safe death tests, remember that they rerun the test
+program from the beginning in the child process. Therefore make sure your
+program can run side-by-side with itself and is deterministic.
+
+In the end, this boils down to good concurrent programming. You have to make
+sure that there is no race conditions or dead locks in your program. No silver
+bullet - sorry!
+
+## Should I use the constructor/destructor of the test fixture or the set-up/tear-down function? ##
+
+The first thing to remember is that Google Test does not reuse the
+same test fixture object across multiple tests. For each `TEST_F`,
+Google Test will create a fresh test fixture object, _immediately_
+call `SetUp()`, run the test body, call `TearDown()`, and then
+_immediately_ delete the test fixture object.
+
+When you need to write per-test set-up and tear-down logic, you have
+the choice between using the test fixture constructor/destructor or
+`SetUp()/TearDown()`. The former is usually preferred, as it has the
+following benefits:
+
+ * By initializing a member variable in the constructor, we have the option to make it `const`, which helps prevent accidental changes to its value and makes the tests more obviously correct.
+ * In case we need to subclass the test fixture class, the subclass' constructor is guaranteed to call the base class' constructor first, and the subclass' destructor is guaranteed to call the base class' destructor afterward. With `SetUp()/TearDown()`, a subclass may make the mistake of forgetting to call the base class' `SetUp()/TearDown()` or call them at the wrong moment.
+
+You may still want to use `SetUp()/TearDown()` in the following rare cases:
+ * If the tear-down operation could throw an exception, you must use `TearDown()` as opposed to the destructor, as throwing in a destructor leads to undefined behavior and usually will kill your program right away. Note that many standard libraries (like STL) may throw when exceptions are enabled in the compiler. Therefore you should prefer `TearDown()` if you want to write portable tests that work with or without exceptions.
+ * The assertion macros throw an exception when flag `--gtest_throw_on_failure` is specified. Therefore, you shouldn't use Google Test assertions in a destructor if you plan to run your tests with this flag.
+ * In a constructor or destructor, you cannot make a virtual function call on this object. (You can call a method declared as virtual, but it will be statically bound.) Therefore, if you need to call a method that will be overridden in a derived class, you have to use `SetUp()/TearDown()`.
+
+## The compiler complains "no matching function to call" when I use ASSERT\_PREDn. How do I fix it? ##
+
+If the predicate function you use in `ASSERT_PRED*` or `EXPECT_PRED*` is
+overloaded or a template, the compiler will have trouble figuring out which
+overloaded version it should use. `ASSERT_PRED_FORMAT*` and
+`EXPECT_PRED_FORMAT*` don't have this problem.
+
+If you see this error, you might want to switch to
+`(ASSERT|EXPECT)_PRED_FORMAT*`, which will also give you a better failure
+message. If, however, that is not an option, you can resolve the problem by
+explicitly telling the compiler which version to pick.
+
+For example, suppose you have
+
+``` cpp
+bool IsPositive(int n) {
+ return n > 0;
+}
+bool IsPositive(double x) {
+ return x > 0;
+}
+```
+
+you will get a compiler error if you write
+
+``` cpp
+EXPECT_PRED1(IsPositive, 5);
+```
+
+However, this will work:
+
+``` cpp
+EXPECT_PRED1(static_cast<bool (*)(int)>(IsPositive), 5);
+```
+
+(The stuff inside the angled brackets for the `static_cast` operator is the
+type of the function pointer for the `int`-version of `IsPositive()`.)
+
+As another example, when you have a template function
+
+``` cpp
+template <typename T>
+bool IsNegative(T x) {
+ return x < 0;
+}
+```
+
+you can use it in a predicate assertion like this:
+
+``` cpp
+ASSERT_PRED1(IsNegative<int>, -5);
+```
+
+Things are more interesting if your template has more than one parameters. The
+following won't compile:
+
+``` cpp
+ASSERT_PRED2(GreaterThan<int, int>, 5, 0);
+```
+
+
+as the C++ pre-processor thinks you are giving `ASSERT_PRED2` 4 arguments,
+which is one more than expected. The workaround is to wrap the predicate
+function in parentheses:
+
+``` cpp
+ASSERT_PRED2((GreaterThan<int, int>), 5, 0);
+```
+
+
+## My compiler complains about "ignoring return value" when I call RUN\_ALL\_TESTS(). Why? ##
+
+Some people had been ignoring the return value of `RUN_ALL_TESTS()`. That is,
+instead of
+
+``` cpp
+return RUN_ALL_TESTS();
+```
+
+they write
+
+``` cpp
+RUN_ALL_TESTS();
+```
+
+This is wrong and dangerous. A test runner needs to see the return value of
+`RUN_ALL_TESTS()` in order to determine if a test has passed. If your `main()`
+function ignores it, your test will be considered successful even if it has a
+Google Test assertion failure. Very bad.
+
+To help the users avoid this dangerous bug, the implementation of
+`RUN_ALL_TESTS()` causes gcc to raise this warning, when the return value is
+ignored. If you see this warning, the fix is simple: just make sure its value
+is used as the return value of `main()`.
+
+## My compiler complains that a constructor (or destructor) cannot return a value. What's going on? ##
+
+Due to a peculiarity of C++, in order to support the syntax for streaming
+messages to an `ASSERT_*`, e.g.
+
+``` cpp
+ASSERT_EQ(1, Foo()) << "blah blah" << foo;
+```
+
+we had to give up using `ASSERT*` and `FAIL*` (but not `EXPECT*` and
+`ADD_FAILURE*`) in constructors and destructors. The workaround is to move the
+content of your constructor/destructor to a private void member function, or
+switch to `EXPECT_*()` if that works. This section in the user's guide explains
+it.
+
+## My set-up function is not called. Why? ##
+
+C++ is case-sensitive. It should be spelled as `SetUp()`. Did you
+spell it as `Setup()`?
+
+Similarly, sometimes people spell `SetUpTestCase()` as `SetupTestCase()` and
+wonder why it's never called.
+
+## How do I jump to the line of a failure in Emacs directly? ##
+
+Google Test's failure message format is understood by Emacs and many other
+IDEs, like acme and XCode. If a Google Test message is in a compilation buffer
+in Emacs, then it's clickable. You can now hit `enter` on a message to jump to
+the corresponding source code, or use `C-x `` to jump to the next failure.
+
+## I have several test cases which share the same test fixture logic, do I have to define a new test fixture class for each of them? This seems pretty tedious. ##
+
+You don't have to. Instead of
+
+``` cpp
+class FooTest : public BaseTest {};
+
+TEST_F(FooTest, Abc) { ... }
+TEST_F(FooTest, Def) { ... }
+
+class BarTest : public BaseTest {};
+
+TEST_F(BarTest, Abc) { ... }
+TEST_F(BarTest, Def) { ... }
+```
+
+you can simply `typedef` the test fixtures:
+``` cpp
+typedef BaseTest FooTest;
+
+TEST_F(FooTest, Abc) { ... }
+TEST_F(FooTest, Def) { ... }
+
+typedef BaseTest BarTest;
+
+TEST_F(BarTest, Abc) { ... }
+TEST_F(BarTest, Def) { ... }
+```
+
+## The Google Test output is buried in a whole bunch of log messages. What do I do? ##
+
+The Google Test output is meant to be a concise and human-friendly report. If
+your test generates textual output itself, it will mix with the Google Test
+output, making it hard to read. However, there is an easy solution to this
+problem.
+
+Since most log messages go to stderr, we decided to let Google Test output go
+to stdout. This way, you can easily separate the two using redirection. For
+example:
+```
+./my_test > googletest_output.txt
+```
+
+## Why should I prefer test fixtures over global variables? ##
+
+There are several good reasons:
+ 1. It's likely your test needs to change the states of its global variables. This makes it difficult to keep side effects from escaping one test and contaminating others, making debugging difficult. By using fixtures, each test has a fresh set of variables that's different (but with the same names). Thus, tests are kept independent of each other.
+ 1. Global variables pollute the global namespace.
+ 1. Test fixtures can be reused via subclassing, which cannot be done easily with global variables. This is useful if many test cases have something in common.
+
+## How do I test private class members without writing FRIEND\_TEST()s? ##
+
+You should try to write testable code, which means classes should be easily
+tested from their public interface. One way to achieve this is the Pimpl idiom:
+you move all private members of a class into a helper class, and make all
+members of the helper class public.
+
+You have several other options that don't require using `FRIEND_TEST`:
+ * Write the tests as members of the fixture class:
+``` cpp
+class Foo {
+ friend class FooTest;
+ ...
+};
+
+class FooTest : public ::testing::Test {
+ protected:
+ ...
+ void Test1() {...} // This accesses private members of class Foo.
+ void Test2() {...} // So does this one.
+};
+
+TEST_F(FooTest, Test1) {
+ Test1();
+}
+
+TEST_F(FooTest, Test2) {
+ Test2();
+}
+```
+ * In the fixture class, write accessors for the tested class' private members, then use the accessors in your tests:
+``` cpp
+class Foo {
+ friend class FooTest;
+ ...
+};
+
+class FooTest : public ::testing::Test {
+ protected:
+ ...
+ T1 get_private_member1(Foo* obj) {
+ return obj->private_member1_;
+ }
+};
+
+TEST_F(FooTest, Test1) {
+ ...
+ get_private_member1(x)
+ ...
+}
+```
+ * If the methods are declared **protected**, you can change their access level in a test-only subclass:
+``` cpp
+class YourClass {
+ ...
+ protected: // protected access for testability.
+ int DoSomethingReturningInt();
+ ...
+};
+
+// in the your_class_test.cc file:
+class TestableYourClass : public YourClass {
+ ...
+ public: using YourClass::DoSomethingReturningInt; // changes access rights
+ ...
+};
+
+TEST_F(YourClassTest, DoSomethingTest) {
+ TestableYourClass obj;
+ assertEquals(expected_value, obj.DoSomethingReturningInt());
+}
+```
+
+## How do I test private class static members without writing FRIEND\_TEST()s? ##
+
+We find private static methods clutter the header file. They are
+implementation details and ideally should be kept out of a .h. So often I make
+them free functions instead.
+
+Instead of:
+``` cpp
+// foo.h
+class Foo {
+ ...
+ private:
+ static bool Func(int n);
+};
+
+// foo.cc
+bool Foo::Func(int n) { ... }
+
+// foo_test.cc
+EXPECT_TRUE(Foo::Func(12345));
+```
+
+You probably should better write:
+``` cpp
+// foo.h
+class Foo {
+ ...
+};
+
+// foo.cc
+namespace internal {
+ bool Func(int n) { ... }
+}
+
+// foo_test.cc
+namespace internal {
+ bool Func(int n);
+}
+
+EXPECT_TRUE(internal::Func(12345));
+```
+
+## I would like to run a test several times with different parameters. Do I need to write several similar copies of it? ##
+
+No. You can use a feature called [value-parameterized tests](AdvancedGuide.md#Value_Parameterized_Tests) which
+lets you repeat your tests with different parameters, without defining it more than once.
+
+## How do I test a file that defines main()? ##
+
+To test a `foo.cc` file, you need to compile and link it into your unit test
+program. However, when the file contains a definition for the `main()`
+function, it will clash with the `main()` of your unit test, and will result in
+a build error.
+
+The right solution is to split it into three files:
+ 1. `foo.h` which contains the declarations,
+ 1. `foo.cc` which contains the definitions except `main()`, and
+ 1. `foo_main.cc` which contains nothing but the definition of `main()`.
+
+Then `foo.cc` can be easily tested.
+
+If you are adding tests to an existing file and don't want an intrusive change
+like this, there is a hack: just include the entire `foo.cc` file in your unit
+test. For example:
+``` cpp
+// File foo_unittest.cc
+
+// The headers section
+...
+
+// Renames main() in foo.cc to make room for the unit test main()
+#define main FooMain
+
+#include "a/b/foo.cc"
+
+// The tests start here.
+...
+```
+
+
+However, please remember this is a hack and should only be used as the last
+resort.
+
+## What can the statement argument in ASSERT\_DEATH() be? ##
+
+`ASSERT_DEATH(_statement_, _regex_)` (or any death assertion macro) can be used
+wherever `_statement_` is valid. So basically `_statement_` can be any C++
+statement that makes sense in the current context. In particular, it can
+reference global and/or local variables, and can be:
+ * a simple function call (often the case),
+ * a complex expression, or
+ * a compound statement.
+
+Some examples are shown here:
+
+``` cpp
+// A death test can be a simple function call.
+TEST(MyDeathTest, FunctionCall) {
+ ASSERT_DEATH(Xyz(5), "Xyz failed");
+}
+
+// Or a complex expression that references variables and functions.
+TEST(MyDeathTest, ComplexExpression) {
+ const bool c = Condition();
+ ASSERT_DEATH((c ? Func1(0) : object2.Method("test")),
+ "(Func1|Method) failed");
+}
+
+// Death assertions can be used any where in a function. In
+// particular, they can be inside a loop.
+TEST(MyDeathTest, InsideLoop) {
+ // Verifies that Foo(0), Foo(1), ..., and Foo(4) all die.
+ for (int i = 0; i < 5; i++) {
+ EXPECT_DEATH_M(Foo(i), "Foo has \\d+ errors",
+ ::testing::Message() << "where i is " << i);
+ }
+}
+
+// A death assertion can contain a compound statement.
+TEST(MyDeathTest, CompoundStatement) {
+ // Verifies that at lease one of Bar(0), Bar(1), ..., and
+ // Bar(4) dies.
+ ASSERT_DEATH({
+ for (int i = 0; i < 5; i++) {
+ Bar(i);
+ }
+ },
+ "Bar has \\d+ errors");}
+```
+
+`googletest_unittest.cc` contains more examples if you are interested.
+
+## What syntax does the regular expression in ASSERT\_DEATH use? ##
+
+On POSIX systems, Google Test uses the POSIX Extended regular
+expression syntax
+(http://en.wikipedia.org/wiki/Regular_expression#POSIX_Extended_Regular_Expressions).
+On Windows, it uses a limited variant of regular expression
+syntax. For more details, see the
+[regular expression syntax](AdvancedGuide.md#Regular_Expression_Syntax).
+
+## I have a fixture class Foo, but TEST\_F(Foo, Bar) gives me error "no matching function for call to Foo::Foo()". Why? ##
+
+Google Test needs to be able to create objects of your test fixture class, so
+it must have a default constructor. Normally the compiler will define one for
+you. However, there are cases where you have to define your own:
+ * If you explicitly declare a non-default constructor for class `Foo`, then you need to define a default constructor, even if it would be empty.
+ * If `Foo` has a const non-static data member, then you have to define the default constructor _and_ initialize the const member in the initializer list of the constructor. (Early versions of `gcc` doesn't force you to initialize the const member. It's a bug that has been fixed in `gcc 4`.)
+
+## Why does ASSERT\_DEATH complain about previous threads that were already joined? ##
+
+With the Linux pthread library, there is no turning back once you cross the
+line from single thread to multiple threads. The first time you create a
+thread, a manager thread is created in addition, so you get 3, not 2, threads.
+Later when the thread you create joins the main thread, the thread count
+decrements by 1, but the manager thread will never be killed, so you still have
+2 threads, which means you cannot safely run a death test.
+
+The new NPTL thread library doesn't suffer from this problem, as it doesn't
+create a manager thread. However, if you don't control which machine your test
+runs on, you shouldn't depend on this.
+
+## Why does Google Test require the entire test case, instead of individual tests, to be named FOODeathTest when it uses ASSERT\_DEATH? ##
+
+Google Test does not interleave tests from different test cases. That is, it
+runs all tests in one test case first, and then runs all tests in the next test
+case, and so on. Google Test does this because it needs to set up a test case
+before the first test in it is run, and tear it down afterwords. Splitting up
+the test case would require multiple set-up and tear-down processes, which is
+inefficient and makes the semantics unclean.
+
+If we were to determine the order of tests based on test name instead of test
+case name, then we would have a problem with the following situation:
+
+``` cpp
+TEST_F(FooTest, AbcDeathTest) { ... }
+TEST_F(FooTest, Uvw) { ... }
+
+TEST_F(BarTest, DefDeathTest) { ... }
+TEST_F(BarTest, Xyz) { ... }
+```
+
+Since `FooTest.AbcDeathTest` needs to run before `BarTest.Xyz`, and we don't
+interleave tests from different test cases, we need to run all tests in the
+`FooTest` case before running any test in the `BarTest` case. This contradicts
+with the requirement to run `BarTest.DefDeathTest` before `FooTest.Uvw`.
+
+## But I don't like calling my entire test case FOODeathTest when it contains both death tests and non-death tests. What do I do? ##
+
+You don't have to, but if you like, you may split up the test case into
+`FooTest` and `FooDeathTest`, where the names make it clear that they are
+related:
+
+``` cpp
+class FooTest : public ::testing::Test { ... };
+
+TEST_F(FooTest, Abc) { ... }
+TEST_F(FooTest, Def) { ... }
+
+typedef FooTest FooDeathTest;
+
+TEST_F(FooDeathTest, Uvw) { ... EXPECT_DEATH(...) ... }
+TEST_F(FooDeathTest, Xyz) { ... ASSERT_DEATH(...) ... }
+```
+
+## The compiler complains about "no match for 'operator<<'" when I use an assertion. What gives? ##
+
+If you use a user-defined type `FooType` in an assertion, you must make sure
+there is an `std::ostream& operator<<(std::ostream&, const FooType&)` function
+defined such that we can print a value of `FooType`.
+
+In addition, if `FooType` is declared in a name space, the `<<` operator also
+needs to be defined in the _same_ name space.
+
+## How do I suppress the memory leak messages on Windows? ##
+
+Since the statically initialized Google Test singleton requires allocations on
+the heap, the Visual C++ memory leak detector will report memory leaks at the
+end of the program run. The easiest way to avoid this is to use the
+`_CrtMemCheckpoint` and `_CrtMemDumpAllObjectsSince` calls to not report any
+statically initialized heap objects. See MSDN for more details and additional
+heap check/debug routines.
+
+## I am building my project with Google Test in Visual Studio and all I'm getting is a bunch of linker errors (or warnings). Help! ##
+
+You may get a number of the following linker error or warnings if you
+attempt to link your test project with the Google Test library when
+your project and the are not built using the same compiler settings.
+
+ * LNK2005: symbol already defined in object
+ * LNK4217: locally defined symbol 'symbol' imported in function 'function'
+ * LNK4049: locally defined symbol 'symbol' imported
+
+The Google Test project (gtest.vcproj) has the Runtime Library option
+set to /MT (use multi-threaded static libraries, /MTd for debug). If
+your project uses something else, for example /MD (use multi-threaded
+DLLs, /MDd for debug), you need to change the setting in the Google
+Test project to match your project's.
+
+To update this setting open the project properties in the Visual
+Studio IDE then select the branch Configuration Properties | C/C++ |
+Code Generation and change the option "Runtime Library". You may also try
+using gtest-md.vcproj instead of gtest.vcproj.
+
+## I put my tests in a library and Google Test doesn't run them. What's happening? ##
+Have you read a
+[warning](Primer.md#important-note-for-visual-c-users) on
+the Google Test Primer page?
+
+## I want to use Google Test with Visual Studio but don't know where to start. ##
+Many people are in your position and one of them posted his solution to our mailing list.
+
+## I am seeing compile errors mentioning std::type\_traits when I try to use Google Test on Solaris. ##
+Google Test uses parts of the standard C++ library that SunStudio does not support.
+Our users reported success using alternative implementations. Try running the build after running this command:
+
+`export CC=cc CXX=CC CXXFLAGS='-library=stlport4'`
+
+## How can my code detect if it is running in a test? ##
+
+If you write code that sniffs whether it's running in a test and does
+different things accordingly, you are leaking test-only logic into
+production code and there is no easy way to ensure that the test-only
+code paths aren't run by mistake in production. Such cleverness also
+leads to
+[Heisenbugs](http://en.wikipedia.org/wiki/Unusual_software_bug#Heisenbug).
+Therefore we strongly advise against the practice, and Google Test doesn't
+provide a way to do it.
+
+In general, the recommended way to cause the code to behave
+differently under test is [dependency injection](http://jamesshore.com/Blog/Dependency-Injection-Demystified.html).
+You can inject different functionality from the test and from the
+production code. Since your production code doesn't link in the
+for-test logic at all, there is no danger in accidentally running it.
+
+However, if you _really_, _really_, _really_ have no choice, and if
+you follow the rule of ending your test program names with `_test`,
+you can use the _horrible_ hack of sniffing your executable name
+(`argv[0]` in `main()`) to know whether the code is under test.
+
+## Google Test defines a macro that clashes with one defined by another library. How do I deal with that? ##
+
+In C++, macros don't obey namespaces. Therefore two libraries that
+both define a macro of the same name will clash if you `#include` both
+definitions. In case a Google Test macro clashes with another
+library, you can force Google Test to rename its macro to avoid the
+conflict.
+
+Specifically, if both Google Test and some other code define macro
+`FOO`, you can add
+```
+ -DGTEST_DONT_DEFINE_FOO=1
+```
+to the compiler flags to tell Google Test to change the macro's name
+from `FOO` to `GTEST_FOO`. For example, with `-DGTEST_DONT_DEFINE_TEST=1`, you'll need to write
+``` cpp
+ GTEST_TEST(SomeTest, DoesThis) { ... }
+```
+instead of
+``` cpp
+ TEST(SomeTest, DoesThis) { ... }
+```
+in order to define a test.
+
+Currently, the following `TEST`, `FAIL`, `SUCCEED`, and the basic comparison assertion macros can have . You can see the full list of covered macros [here](../include/gtest/gtest.h). More information can be found in the "Avoiding Macro Name Clashes" section of the README file.
+
+
+## Is it OK if I have two separate `TEST(Foo, Bar)` test methods defined in different namespaces? ##
+
+Yes.
+
+The rule is **all test methods in the same test case must use the same fixture class**. This means that the following is **allowed** because both tests use the same fixture class (`::testing::Test`).
+
+``` cpp
+namespace foo {
+TEST(CoolTest, DoSomething) {
+ SUCCEED();
+}
+} // namespace foo
+
+namespace bar {
+TEST(CoolTest, DoSomething) {
+ SUCCEED();
+}
+} // namespace bar
+```
+
+However, the following code is **not allowed** and will produce a runtime error from Google Test because the test methods are using different test fixture classes with the same test case name.
+
+``` cpp
+namespace foo {
+class CoolTest : public ::testing::Test {}; // Fixture foo::CoolTest
+TEST_F(CoolTest, DoSomething) {
+ SUCCEED();
+}
+} // namespace foo
+
+namespace bar {
+class CoolTest : public ::testing::Test {}; // Fixture: bar::CoolTest
+TEST_F(CoolTest, DoSomething) {
+ SUCCEED();
+}
+} // namespace bar
+```
+
+## How do I build Google Testing Framework with Xcode 4? ##
+
+If you try to build Google Test's Xcode project with Xcode 4.0 or later, you may encounter an error message that looks like
+"Missing SDK in target gtest\_framework: /Developer/SDKs/MacOSX10.4u.sdk". That means that Xcode does not support the SDK the project is targeting. See the Xcode section in the [README](../README.md) file on how to resolve this.
+
+## How do I easily discover the flags needed for GoogleTest? ##
+
+GoogleTest (and GoogleMock) now support discovering all necessary flags using pkg-config.
+See the [pkg-config guide](Pkgconfig.md) on how you can easily discover all compiler and
+linker flags using pkg-config.

+## Using GoogleTest from various build systems ##
+
+GoogleTest comes with pkg-config files that can be used to determine all
+necessary flags for compiling and linking to GoogleTest (and GoogleMock).
+Pkg-config is a standardised plain-text format containing
+
+ * the includedir (-I) path
+ * necessary macro (-D) definitions
+ * further required flags (-pthread)
+ * the library (-L) path
+ * the library (-l) to link to
+
+All current build systems support pkg-config in one way or another. For
+all examples here we assume you want to compile the sample
+`samples/sample3_unittest.cc`.
+
+
+### CMake ###
+
+Using `pkg-config` in CMake is fairly easy:
+
+```
+cmake_minimum_required(VERSION 3.0)
+
+cmake_policy(SET CMP0048 NEW)
+project(my_gtest_pkgconfig VERSION 0.0.1 LANGUAGES CXX)
+
+find_package(PkgConfig)
+pkg_search_module(GTEST REQUIRED gtest_main)
+
+add_executable(testapp samples/sample3_unittest.cc)
+target_link_libraries(testapp ${GTEST_LDFLAGS})
+target_compile_options(testapp PUBLIC ${GTEST_CFLAGS})
+
+include(CTest)
+add_test(first_and_only_test testapp)
+```
+
+It is generally recommended that you use `target_compile_options` + `_CFLAGS`
+over `target_include_directories` + `_INCLUDE_DIRS` as the former includes not
+just -I flags (GoogleTest might require a macro indicating to internal headers
+that all libraries have been compiled with threading enabled. In addition,
+GoogleTest might also require `-pthread` in the compiling step, and as such
+splitting the pkg-config `Cflags` variable into include dirs and macros for
+`target_compile_definitions()` might still miss this). The same recommendation
+goes for using `_LDFLAGS` over the more commonplace `_LIBRARIES`, which
+happens to discard `-L` flags and `-pthread`.
+
+
+### Autotools ###
+
+Finding GoogleTest in Autoconf and using it from Automake is also fairly easy:
+
+In your `configure.ac`:
+
+```
+AC_PREREQ([2.69])
+AC_INIT([my_gtest_pkgconfig], [0.0.1])
+AC_CONFIG_SRCDIR([samples/sample3_unittest.cc])
+AC_PROG_CXX
+
+PKG_CHECK_MODULES([GTEST], [gtest_main])
+
+AM_INIT_AUTOMAKE([foreign subdir-objects])
+AC_CONFIG_FILES([Makefile])
+AC_OUTPUT
+```
+
+and in your `Makefile.am`:
+
+```
+check_PROGRAMS = testapp
+TESTS = $(check_PROGRAMS)
+
+testapp_SOURCES = samples/sample3_unittest.cc
+testapp_CXXFLAGS = $(GTEST_CFLAGS)
+testapp_LDADD = $(GTEST_LIBS)
+```
+
+
+### Meson ###
+
+Meson natively uses pkgconfig to query dependencies:
+
+```
+project('my_gtest_pkgconfig', 'cpp', version : '0.0.1')
+
+gtest_dep = dependency('gtest_main')
+
+testapp = executable(
+ 'testapp',
+ files(['samples/sample3_unittest.cc']),
+ dependencies : gtest_dep,
+ install : false)
+
+test('first_and_only_test', testapp)
+```
+
+
+### Plain Makefiles ###
+
+Since `pkg-config` is a small Unix command-line utility, it can be used
+in handwritten `Makefile`s too:
+
+```
+GTEST_CFLAGS = `pkg-config --cflags gtest_main`
+GTEST_LIBS = `pkg-config --libs gtest_main`
+
+.PHONY: tests all
+
+tests: all
+ ./testapp
+
+all: testapp
+
+testapp: testapp.o
+ $(CXX) $(CXXFLAGS) $(LDFLAGS) $< -o $@ $(GTEST_LIBS)
+
+testapp.o: samples/sample3_unittest.cc
+ $(CXX) $(CPPFLAGS) $(CXXFLAGS) $< -c -o $@ $(GTEST_CFLAGS)
+```
+
+
+### Help! pkg-config can't find GoogleTest! ###
+
+Let's say you have a `CMakeLists.txt` along the lines of the one in this
+tutorial and you try to run `cmake`. It is very possible that you get a
+failure along the lines of:
+
+```
+-- Checking for one of the modules 'gtest_main'
+CMake Error at /usr/share/cmake/Modules/FindPkgConfig.cmake:640 (message):
+ None of the required 'gtest_main' found
+```
+
+These failures are common if you installed GoogleTest yourself and have not
+sourced it from a distro or other package manager. If so, you need to tell
+pkg-config where it can find the `.pc` files containing the information.
+Say you installed GoogleTest to `/usr/local`, then it might be that the
+`.pc` files are installed under `/usr/local/lib64/pkgconfig`. If you set
+
+```
+export PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig
+```
+
+pkg-config will also try to look in `PKG_CONFIG_PATH` to find `gtest_main.pc`.

+# Introduction: Why Google C++ Testing Framework? #
+
+_Google C++ Testing Framework_ helps you write better C++ tests.
+
+No matter whether you work on Linux, Windows, or a Mac, if you write C++ code,
+Google Test can help you.
+
+So what makes a good test, and how does Google C++ Testing Framework fit in? We believe:
+ 1. Tests should be _independent_ and _repeatable_. It's a pain to debug a test that succeeds or fails as a result of other tests. Google C++ Testing Framework isolates the tests by running each of them on a different object. When a test fails, Google C++ Testing Framework allows you to run it in isolation for quick debugging.
+ 1. Tests should be well _organized_ and reflect the structure of the tested code. Google C++ Testing Framework groups related tests into test cases that can share data and subroutines. This common pattern is easy to recognize and makes tests easy to maintain. Such consistency is especially helpful when people switch projects and start to work on a new code base.
+ 1. Tests should be _portable_ and _reusable_. The open-source community has a lot of code that is platform-neutral, its tests should also be platform-neutral. Google C++ Testing Framework works on different OSes, with different compilers (gcc, MSVC, and others), with or without exceptions, so Google C++ Testing Framework tests can easily work with a variety of configurations. (Note that the current release only contains build scripts for Linux - we are actively working on scripts for other platforms.)
+ 1. When tests fail, they should provide as much _information_ about the problem as possible. Google C++ Testing Framework doesn't stop at the first test failure. Instead, it only stops the current test and continues with the next. You can also set up tests that report non-fatal failures after which the current test continues. Thus, you can detect and fix multiple bugs in a single run-edit-compile cycle.
+ 1. The testing framework should liberate test writers from housekeeping chores and let them focus on the test _content_. Google C++ Testing Framework automatically keeps track of all tests defined, and doesn't require the user to enumerate them in order to run them.
+ 1. Tests should be _fast_. With Google C++ Testing Framework, you can reuse shared resources across tests and pay for the set-up/tear-down only once, without making tests depend on each other.
+
+Since Google C++ Testing Framework is based on the popular xUnit
+architecture, you'll feel right at home if you've used JUnit or PyUnit before.
+If not, it will take you about 10 minutes to learn the basics and get started.
+So let's go!
+
+_Note:_ We sometimes refer to Google C++ Testing Framework informally
+as _Google Test_.
+
+# Beware of the nomenclature #
+
+_Note:_ There might be some confusion of idea due to different
+definitions of the terms _Test_, _Test Case_ and _Test Suite_, so beware
+of misunderstanding these.
+
+Historically, the Google C++ Testing Framework started to use the term
+_Test Case_ for grouping related tests, whereas current publications
+including the International Software Testing Qualifications Board
+([ISTQB](http://www.istqb.org/)) and various textbooks on Software
+Quality use the term _[Test
+Suite](http://glossary.istqb.org/search/test%20suite)_ for this.
+
+The related term _Test_, as it is used in the Google C++ Testing
+Framework, is corresponding to the term _[Test
+Case](http://glossary.istqb.org/search/test%20case)_ of ISTQB and
+others.
+
+The term _Test_ is commonly of broad enough sense, including ISTQB's
+definition of _Test Case_, so it's not much of a problem here. But the
+term _Test Case_ as used in Google Test is of contradictory sense and thus confusing.
+
+Unfortunately replacing the term _Test Case_ by _Test Suite_ throughout
+the Google C++ Testing Framework is not easy without breaking dependent
+projects, as `TestCase` is part of the public API at various places.
+
+So for the time being, please be aware of the different definitions of
+the terms:
+
+Meaning | Google Test Term | [ISTQB](http://www.istqb.org/) Term
+------- | ---------------- | -----------------------------------
+Exercise a particular program path with specific input values and verify the results | [TEST()](#simple-tests) | [Test Case](http://glossary.istqb.org/search/test%20case)
+A set of several tests related to one component | [Test Case](#basic-concepts) | [Test Suite](http://glossary.istqb.org/search/test%20suite)
+
+# Setting up a New Test Project #
+
+To write a test program using Google Test, you need to compile Google
+Test into a library and link your test with it. We provide build
+files for some popular build systems: `msvc/` for Visual Studio,
+`xcode/` for Mac Xcode, `make/` for GNU make, `codegear/` for Borland
+C++ Builder, and the autotools script (deprecated) and
+`CMakeLists.txt` for CMake (recommended) in the Google Test root
+directory. If your build system is not on this list, you can take a
+look at `make/Makefile` to learn how Google Test should be compiled
+(basically you want to compile `src/gtest-all.cc` with `GTEST_ROOT`
+and `GTEST_ROOT/include` in the header search path, where `GTEST_ROOT`
+is the Google Test root directory).
+
+Once you are able to compile the Google Test library, you should
+create a project or build target for your test program. Make sure you
+have `GTEST_ROOT/include` in the header search path so that the
+compiler can find `"gtest/gtest.h"` when compiling your test. Set up
+your test project to link with the Google Test library (for example,
+in Visual Studio, this is done by adding a dependency on
+`gtest.vcproj`).
+
+If you still have questions, take a look at how Google Test's own
+tests are built and use them as examples.
+
+# Basic Concepts #
+
+When using Google Test, you start by writing _assertions_, which are statements
+that check whether a condition is true. An assertion's result can be _success_,
+_nonfatal failure_, or _fatal failure_. If a fatal failure occurs, it aborts
+the current function; otherwise the program continues normally.
+
+_Tests_ use assertions to verify the tested code's behavior. If a test crashes
+or has a failed assertion, then it _fails_; otherwise it _succeeds_.
+
+A _test case_ contains one or many tests. You should group your tests into test
+cases that reflect the structure of the tested code. When multiple tests in a
+test case need to share common objects and subroutines, you can put them into a
+_test fixture_ class.
+
+A _test program_ can contain multiple test cases.
+
+We'll now explain how to write a test program, starting at the individual
+assertion level and building up to tests and test cases.
+
+# Assertions #
+
+Google Test assertions are macros that resemble function calls. You test a
+class or function by making assertions about its behavior. When an assertion
+fails, Google Test prints the assertion's source file and line number location,
+along with a failure message. You may also supply a custom failure message
+which will be appended to Google Test's message.
+
+The assertions come in pairs that test the same thing but have different
+effects on the current function. `ASSERT_*` versions generate fatal failures
+when they fail, and **abort the current function**. `EXPECT_*` versions generate
+nonfatal failures, which don't abort the current function. Usually `EXPECT_*`
+are preferred, as they allow more than one failures to be reported in a test.
+However, you should use `ASSERT_*` if it doesn't make sense to continue when
+the assertion in question fails.
+
+Since a failed `ASSERT_*` returns from the current function immediately,
+possibly skipping clean-up code that comes after it, it may cause a space leak.
+Depending on the nature of the leak, it may or may not be worth fixing - so
+keep this in mind if you get a heap checker error in addition to assertion
+errors.
+
+To provide a custom failure message, simply stream it into the macro using the
+`<<` operator, or a sequence of such operators. An example:
+```
+ASSERT_EQ(x.size(), y.size()) << "Vectors x and y are of unequal length";
+
+for (int i = 0; i < x.size(); ++i) {
+ EXPECT_EQ(x[i], y[i]) << "Vectors x and y differ at index " << i;
+}
+```
+
+Anything that can be streamed to an `ostream` can be streamed to an assertion
+macro--in particular, C strings and `string` objects. If a wide string
+(`wchar_t*`, `TCHAR*` in `UNICODE` mode on Windows, or `std::wstring`) is
+streamed to an assertion, it will be translated to UTF-8 when printed.
+
+## Basic Assertions ##
+
+These assertions do basic true/false condition testing.
+
+| **Fatal assertion** | **Nonfatal assertion** | **Verifies** |
+|:--------------------|:-----------------------|:-------------|
+| `ASSERT_TRUE(`_condition_`)`; | `EXPECT_TRUE(`_condition_`)`; | _condition_ is true |
+| `ASSERT_FALSE(`_condition_`)`; | `EXPECT_FALSE(`_condition_`)`; | _condition_ is false |
+
+Remember, when they fail, `ASSERT_*` yields a fatal failure and
+returns from the current function, while `EXPECT_*` yields a nonfatal
+failure, allowing the function to continue running. In either case, an
+assertion failure means its containing test fails.
+
+_Availability_: Linux, Windows, Mac.
+
+## Binary Comparison ##
+
+This section describes assertions that compare two values.
+
+| **Fatal assertion** | **Nonfatal assertion** | **Verifies** |
+|:--------------------|:-----------------------|:-------------|
+|`ASSERT_EQ(`_val1_`, `_val2_`);`|`EXPECT_EQ(`_val1_`, `_val2_`);`| _val1_ `==` _val2_ |
+|`ASSERT_NE(`_val1_`, `_val2_`);`|`EXPECT_NE(`_val1_`, `_val2_`);`| _val1_ `!=` _val2_ |
+|`ASSERT_LT(`_val1_`, `_val2_`);`|`EXPECT_LT(`_val1_`, `_val2_`);`| _val1_ `<` _val2_ |
+|`ASSERT_LE(`_val1_`, `_val2_`);`|`EXPECT_LE(`_val1_`, `_val2_`);`| _val1_ `<=` _val2_ |
+|`ASSERT_GT(`_val1_`, `_val2_`);`|`EXPECT_GT(`_val1_`, `_val2_`);`| _val1_ `>` _val2_ |
+|`ASSERT_GE(`_val1_`, `_val2_`);`|`EXPECT_GE(`_val1_`, `_val2_`);`| _val1_ `>=` _val2_ |
+
+In the event of a failure, Google Test prints both _val1_ and _val2_.
+
+Value arguments must be comparable by the assertion's comparison
+operator or you'll get a compiler error. We used to require the
+arguments to support the `<<` operator for streaming to an `ostream`,
+but it's no longer necessary since v1.6.0 (if `<<` is supported, it
+will be called to print the arguments when the assertion fails;
+otherwise Google Test will attempt to print them in the best way it
+can. For more details and how to customize the printing of the
+arguments, see this Google Mock [recipe](../../googlemock/docs/CookBook.md#teaching-google-mock-how-to-print-your-values).).
+
+These assertions can work with a user-defined type, but only if you define the
+corresponding comparison operator (e.g. `==`, `<`, etc). If the corresponding
+operator is defined, prefer using the `ASSERT_*()` macros because they will
+print out not only the result of the comparison, but the two operands as well.
+
+Arguments are always evaluated exactly once. Therefore, it's OK for the
+arguments to have side effects. However, as with any ordinary C/C++ function,
+the arguments' evaluation order is undefined (i.e. the compiler is free to
+choose any order) and your code should not depend on any particular argument
+evaluation order.
+
+`ASSERT_EQ()` does pointer equality on pointers. If used on two C strings, it
+tests if they are in the same memory location, not if they have the same value.
+Therefore, if you want to compare C strings (e.g. `const char*`) by value, use
+`ASSERT_STREQ()` , which will be described later on. In particular, to assert
+that a C string is `NULL`, use `ASSERT_STREQ(NULL, c_string)` . However, to
+compare two `string` objects, you should use `ASSERT_EQ`.
+
+Macros in this section work with both narrow and wide string objects (`string`
+and `wstring`).
+
+_Availability_: Linux, Windows, Mac.
+
+_Historical note_: Before February 2016 `*_EQ` had a convention of calling it as
+`ASSERT_EQ(expected, actual)`, so lots of existing code uses this order.
+Now `*_EQ` treats both parameters in the same way.
+
+## String Comparison ##
+
+The assertions in this group compare two **C strings**. If you want to compare
+two `string` objects, use `EXPECT_EQ`, `EXPECT_NE`, and etc instead.
+
+| **Fatal assertion** | **Nonfatal assertion** | **Verifies** |
+|:--------------------|:-----------------------|:-------------|
+| `ASSERT_STREQ(`_str1_`, `_str2_`);` | `EXPECT_STREQ(`_str1_`, `_str2_`);` | the two C strings have the same content |
+| `ASSERT_STRNE(`_str1_`, `_str2_`);` | `EXPECT_STRNE(`_str1_`, `_str2_`);` | the two C strings have different content |
+| `ASSERT_STRCASEEQ(`_str1_`, `_str2_`);`| `EXPECT_STRCASEEQ(`_str1_`, `_str2_`);` | the two C strings have the same content, ignoring case |
+| `ASSERT_STRCASENE(`_str1_`, `_str2_`);`| `EXPECT_STRCASENE(`_str1_`, `_str2_`);` | the two C strings have different content, ignoring case |
+
+Note that "CASE" in an assertion name means that case is ignored.
+
+`*STREQ*` and `*STRNE*` also accept wide C strings (`wchar_t*`). If a
+comparison of two wide strings fails, their values will be printed as UTF-8
+narrow strings.
+
+A `NULL` pointer and an empty string are considered _different_.
+
+_Availability_: Linux, Windows, Mac.
+

+regular expression matching, for example), see the [Advanced Google Test Guide](AdvancedGuide.md).
+
+# Simple Tests #
+
+To create a test:
+ 1. Use the `TEST()` macro to define and name a test function, These are ordinary C++ functions that don't return a value.
+ 1. In this function, along with any valid C++ statements you want to include, use the various Google Test assertions to check values.
+ 1. The test's result is determined by the assertions; if any assertion in the test fails (either fatally or non-fatally), or if the test crashes, the entire test fails. Otherwise, it succeeds.
+
+```
+TEST(testCaseName, testName) {
+ ... test body ...
+}
+```
+
+
+`TEST()` arguments go from general to specific. The _first_ argument is the
+name of the test case, and the _second_ argument is the test's name within the
+test case. Both names must be valid C++ identifiers, and they should not contain underscore (`_`). A test's _full name_ consists of its containing test case and its
+individual name. Tests from different test cases can have the same individual
+name.
+
+For example, let's take a simple integer function:
+```
+int Factorial(int n); // Returns the factorial of n
+```
+
+A test case for this function might look like:
+```
+// Tests factorial of 0.
+TEST(FactorialTest, HandlesZeroInput) {
+ EXPECT_EQ(1, Factorial(0));
+}
+
+// Tests factorial of positive numbers.
+TEST(FactorialTest, HandlesPositiveInput) {
+ EXPECT_EQ(1, Factorial(1));
+ EXPECT_EQ(2, Factorial(2));
+ EXPECT_EQ(6, Factorial(3));
+ EXPECT_EQ(40320, Factorial(8));
+}
+```
+
+Google Test groups the test results by test cases, so logically-related tests
+should be in the same test case; in other words, the first argument to their
+`TEST()` should be the same. In the above example, we have two tests,
+`HandlesZeroInput` and `HandlesPositiveInput`, that belong to the same test
+case `FactorialTest`.
+
+_Availability_: Linux, Windows, Mac.
+
+# Test Fixtures: Using the Same Data Configuration for Multiple Tests #
+
+If you find yourself writing two or more tests that operate on similar data,
+you can use a _test fixture_. It allows you to reuse the same configuration of
+objects for several different tests.
+
+To create a fixture, just:
+ 1. Derive a class from `::testing::Test` . Start its body with `protected:` or `public:` as we'll want to access fixture members from sub-classes.
+ 1. Inside the class, declare any objects you plan to use.
+ 1. If necessary, write a default constructor or `SetUp()` function to prepare the objects for each test. A common mistake is to spell `SetUp()` as `Setup()` with a small `u` - don't let that happen to you.
+ 1. If necessary, write a destructor or `TearDown()` function to release any resources you allocated in `SetUp()` . To learn when you should use the constructor/destructor and when you should use `SetUp()/TearDown()`, read this [FAQ entry](FAQ.md#should-i-use-the-constructordestructor-of-the-test-fixture-or-the-set-uptear-down-function).
+ 1. If needed, define subroutines for your tests to share.
+
+When using a fixture, use `TEST_F()` instead of `TEST()` as it allows you to
+access objects and subroutines in the test fixture:
+```
+TEST_F(test_case_name, test_name) {
+ ... test body ...
+}
+```
+
+Like `TEST()`, the first argument is the test case name, but for `TEST_F()`
+this must be the name of the test fixture class. You've probably guessed: `_F`
+is for fixture.
+
+Unfortunately, the C++ macro system does not allow us to create a single macro
+that can handle both types of tests. Using the wrong macro causes a compiler
+error.
+
+Also, you must first define a test fixture class before using it in a
+`TEST_F()`, or you'll get the compiler error "`virtual outside class
+declaration`".
+
+For each test defined with `TEST_F()`, Google Test will:
+ 1. Create a _fresh_ test fixture at runtime
+ 1. Immediately initialize it via `SetUp()`
+ 1. Run the test
+ 1. Clean up by calling `TearDown()`
+ 1. Delete the test fixture. Note that different tests in the same test case have different test fixture objects, and Google Test always deletes a test fixture before it creates the next one. Google Test does not reuse the same test fixture for multiple tests. Any changes one test makes to the fixture do not affect other tests.
+
+As an example, let's write tests for a FIFO queue class named `Queue`, which
+has the following interface:
+```
+template <typename E> // E is the element type.
+class Queue {
+ public:
+ Queue();
+ void Enqueue(const E& element);
+ E* Dequeue(); // Returns NULL if the queue is empty.
+ size_t size() const;
+ ...
+};
+```
+
+First, define a fixture class. By convention, you should give it the name
+`FooTest` where `Foo` is the class being tested.
+```
+class QueueTest : public ::testing::Test {
+ protected:
+ virtual void SetUp() {
+ q1_.Enqueue(1);
+ q2_.Enqueue(2);
+ q2_.Enqueue(3);
+ }
+
+ // virtual void TearDown() {}
+
+ Queue<int> q0_;
+ Queue<int> q1_;
+ Queue<int> q2_;
+};
+```
+
+In this case, `TearDown()` is not needed since we don't have to clean up after
+each test, other than what's already done by the destructor.
+
+Now we'll write tests using `TEST_F()` and this fixture.
+```
+TEST_F(QueueTest, IsEmptyInitially) {
+ EXPECT_EQ(0, q0_.size());
+}
+
+TEST_F(QueueTest, DequeueWorks) {
+ int* n = q0_.Dequeue();
+ EXPECT_EQ(NULL, n);
+
+ n = q1_.Dequeue();
+ ASSERT_TRUE(n != NULL);
+ EXPECT_EQ(1, *n);
+ EXPECT_EQ(0, q1_.size());
+ delete n;
+
+ n = q2_.Dequeue();
+ ASSERT_TRUE(n != NULL);
+ EXPECT_EQ(2, *n);
+ EXPECT_EQ(1, q2_.size());
+ delete n;
+}
+```
+
+The above uses both `ASSERT_*` and `EXPECT_*` assertions. The rule of thumb is
+to use `EXPECT_*` when you want the test to continue to reveal more errors
+after the assertion failure, and use `ASSERT_*` when continuing after failure
+doesn't make sense. For example, the second assertion in the `Dequeue` test is
+`ASSERT_TRUE(n != NULL)`, as we need to dereference the pointer `n` later,
+which would lead to a segfault when `n` is `NULL`.
+
+When these tests run, the following happens:
+ 1. Google Test constructs a `QueueTest` object (let's call it `t1` ).
+ 1. `t1.SetUp()` initializes `t1` .
+ 1. The first test ( `IsEmptyInitially` ) runs on `t1` .
+ 1. `t1.TearDown()` cleans up after the test finishes.
+ 1. `t1` is destructed.
+ 1. The above steps are repeated on another `QueueTest` object, this time running the `DequeueWorks` test.
+
+_Availability_: Linux, Windows, Mac.
+
+_Note_: Google Test automatically saves all _Google Test_ flags when a test
+object is constructed, and restores them when it is destructed.
+
+# Invoking the Tests #
+
+`TEST()` and `TEST_F()` implicitly register their tests with Google Test. So, unlike with many other C++ testing frameworks, you don't have to re-list all your defined tests in order to run them.
+
+After defining your tests, you can run them with `RUN_ALL_TESTS()` , which returns `0` if all the tests are successful, or `1` otherwise. Note that `RUN_ALL_TESTS()` runs _all tests_ in your link unit -- they can be from different test cases, or even different source files.
+
+When invoked, the `RUN_ALL_TESTS()` macro:
+ 1. Saves the state of all Google Test flags.
+ 1. Creates a test fixture object for the first test.
+ 1. Initializes it via `SetUp()`.
+ 1. Runs the test on the fixture object.
+ 1. Cleans up the fixture via `TearDown()`.
+ 1. Deletes the fixture.
+ 1. Restores the state of all Google Test flags.
+ 1. Repeats the above steps for the next test, until all tests have run.
+
+In addition, if the test fixture's constructor generates a fatal failure in
+step 2, there is no point for step 3 - 5 and they are thus skipped. Similarly,
+if step 3 generates a fatal failure, step 4 will be skipped.
+
+_Important_: You must not ignore the return value of `RUN_ALL_TESTS()`, or `gcc`
+will give you a compiler error. The rationale for this design is that the
+automated testing service determines whether a test has passed based on its
+exit code, not on its stdout/stderr output; thus your `main()` function must
+return the value of `RUN_ALL_TESTS()`.
+
+Also, you should call `RUN_ALL_TESTS()` only **once**. Calling it more than once
+conflicts with some advanced Google Test features (e.g. thread-safe death
+tests) and thus is not supported.
+
+_Availability_: Linux, Windows, Mac.
+
+# Writing the main() Function #
+
+You can start from this boilerplate:
+```
+#include "this/package/foo.h"
+#include "gtest/gtest.h"
+
+namespace {
+
+// The fixture for testing class Foo.
+class FooTest : public ::testing::Test {
+ protected:
+ // You can remove any or all of the following functions if its body
+ // is empty.
+
+ FooTest() {
+ // You can do set-up work for each test here.
+ }
+
+ virtual ~FooTest() {
+ // You can do clean-up work that doesn't throw exceptions here.
+ }
+
+ // If the constructor and destructor are not enough for setting up
+ // and cleaning up each test, you can define the following methods:
+
+ virtual void SetUp() {
+ // Code here will be called immediately after the constructor (right
+ // before each test).
+ }
+
+ virtual void TearDown() {
+ // Code here will be called immediately after each test (right
+ // before the destructor).
+ }
+
+ // Objects declared here can be used by all tests in the test case for Foo.
+};
+
+// Tests that the Foo::Bar() method does Abc.
+TEST_F(FooTest, MethodBarDoesAbc) {
+ const string input_filepath = "this/package/testdata/myinputfile.dat";
+ const string output_filepath = "this/package/testdata/myoutputfile.dat";
+ Foo f;
+ EXPECT_EQ(0, f.Bar(input_filepath, output_filepath));
+}
+
+// Tests that Foo does Xyz.
+TEST_F(FooTest, DoesXyz) {
+ // Exercises the Xyz feature of Foo.
+}
+
+} // namespace
+
+int main(int argc, char **argv) {
+ ::testing::InitGoogleTest(&argc, argv);
+ return RUN_ALL_TESTS();
+}
+```
+
+The `::testing::InitGoogleTest()` function parses the command line for Google
+Test flags, and removes all recognized flags. This allows the user to control a
+test program's behavior via various flags, which we'll cover in [AdvancedGuide](AdvancedGuide.md).
+You must call this function before calling `RUN_ALL_TESTS()`, or the flags
+won't be properly initialized.
+
+On Windows, `InitGoogleTest()` also works with wide strings, so it can be used
+in programs compiled in `UNICODE` mode as well.
+
+But maybe you think that writing all those main() functions is too much work? We agree with you completely and that's why Google Test provides a basic implementation of main(). If it fits your needs, then just link your test with gtest\_main library and you are good to go.
+
+## Important note for Visual C++ users ##
+If you put your tests into a library and your `main()` function is in a different library or in your .exe file, those tests will not run. The reason is a [bug](https://connect.microsoft.com/feedback/viewfeedback.aspx?FeedbackID=244410&siteid=210) in Visual C++. When you define your tests, Google Test creates certain static objects to register them. These objects are not referenced from elsewhere but their constructors are still supposed to run. When Visual C++ linker sees that nothing in the library is referenced from other places it throws the library out. You have to reference your library with tests from your main program to keep the linker from discarding it. Here is how to do it. Somewhere in your library code declare a function:
+```
+__declspec(dllexport) int PullInMyLibrary() { return 0; }
+```
+If you put your tests in a static library (not DLL) then `__declspec(dllexport)` is not required. Now, in your main program, write a code that invokes that function:
+```
+int PullInMyLibrary();
+static int dummy = PullInMyLibrary();
+```
+This will keep your tests referenced and will make them register themselves at startup.
+
+In addition, if you define your tests in a static library, add `/OPT:NOREF` to your main program linker options. If you use MSVC++ IDE, go to your .exe project properties/Configuration Properties/Linker/Optimization and set References setting to `Keep Unreferenced Data (/OPT:NOREF)`. This will keep Visual C++ linker from discarding individual symbols generated by your tests from the final executable.
+
+There is one more pitfall, though. If you use Google Test as a static library (that's how it is defined in gtest.vcproj) your tests must also reside in a static library. If you have to have them in a DLL, you _must_ change Google Test to build into a DLL as well. Otherwise your tests will not run correctly or will not run at all. The general conclusion here is: make your life easier - do not write your tests in libraries!
+
+# Where to Go from Here #
+
+Congratulations! You've learned the Google Test basics. You can start writing
+and running Google Test tests, read some [samples](Samples.md), or continue with
+[AdvancedGuide](AdvancedGuide.md), which describes many more useful Google Test features.
+
+# Known Limitations #
+
+Google Test is designed to be thread-safe. The implementation is
+thread-safe on systems where the `pthreads` library is available. It
+is currently _unsafe_ to use Google Test assertions from two threads
+concurrently on other systems (e.g. Windows). In most tests this is
+not an issue as usually the assertions are done in the main thread. If
+you want to help, you can volunteer to implement the necessary
+synchronization primitives in `gtest-port.h` for your platform.

+
+# The Problem #
+
+Template and macro libraries often need to define many classes,
+functions, or macros that vary only (or almost only) in the number of
+arguments they take. It's a lot of repetitive, mechanical, and
+error-prone work.
+
+Variadic templates and variadic macros can alleviate the problem.
+However, while both are being considered by the C++ committee, neither
+is in the standard yet or widely supported by compilers. Thus they
+are often not a good choice, especially when your code needs to be
+portable. And their capabilities are still limited.
+
+As a result, authors of such libraries often have to write scripts to
+generate their implementation. However, our experience is that it's
+tedious to write such scripts, which tend to reflect the structure of
+the generated code poorly and are often hard to read and edit. For
+example, a small change needed in the generated code may require some
+non-intuitive, non-trivial changes in the script. This is especially
+painful when experimenting with the code.
+
+# Our Solution #
+
+Pump (for Pump is Useful for Meta Programming, Pretty Useful for Meta
+Programming, or Practical Utility for Meta Programming, whichever you
+prefer) is a simple meta-programming tool for C++. The idea is that a
+programmer writes a `foo.pump` file which contains C++ code plus meta
+code that manipulates the C++ code. The meta code can handle
+iterations over a range, nested iterations, local meta variable
+definitions, simple arithmetic, and conditional expressions. You can
+view it as a small Domain-Specific Language. The meta language is
+designed to be non-intrusive (s.t. it won't confuse Emacs' C++ mode,
+for example) and concise, making Pump code intuitive and easy to
+maintain.
+
+## Highlights ##
+
+ * The implementation is in a single Python script and thus ultra portable: no build or installation is needed and it works cross platforms.
+ * Pump tries to be smart with respect to [Google's style guide](https://github.com/google/styleguide): it breaks long lines (easy to have when they are generated) at acceptable places to fit within 80 columns and indent the continuation lines correctly.
+ * The format is human-readable and more concise than XML.
+ * The format works relatively well with Emacs' C++ mode.
+
+## Examples ##
+
+The following Pump code (where meta keywords start with `$`, `[[` and `]]` are meta brackets, and `$$` starts a meta comment that ends with the line):
+
+```
+$var n = 3 $$ Defines a meta variable n.
+$range i 0..n $$ Declares the range of meta iterator i (inclusive).
+$for i [[
+ $$ Meta loop.
+// Foo$i does blah for $i-ary predicates.
+$range j 1..i
+template <size_t N $for j [[, typename A$j]]>
+class Foo$i {
+$if i == 0 [[
+ blah a;
+]] $elif i <= 2 [[
+ blah b;
+]] $else [[
+ blah c;
+]]
+};
+
+]]
+```
+
+will be translated by the Pump compiler to:
+
+```
+// Foo0 does blah for 0-ary predicates.
+template <size_t N>
+class Foo0 {
+ blah a;
+};
+
+// Foo1 does blah for 1-ary predicates.
+template <size_t N, typename A1>
+class Foo1 {
+ blah b;
+};
+
+// Foo2 does blah for 2-ary predicates.
+template <size_t N, typename A1, typename A2>
+class Foo2 {
+ blah b;
+};
+
+// Foo3 does blah for 3-ary predicates.
+template <size_t N, typename A1, typename A2, typename A3>
+class Foo3 {
+ blah c;
+};
+```
+
+In another example,
+
+```
+$range i 1..n
+Func($for i + [[a$i]]);
+$$ The text between i and [[ is the separator between iterations.
+```
+
+will generate one of the following lines (without the comments), depending on the value of `n`:
+
+```
+Func(); // If n is 0.
+Func(a1); // If n is 1.
+Func(a1 + a2); // If n is 2.
+Func(a1 + a2 + a3); // If n is 3.
+// And so on...
+```
+
+## Constructs ##
+
+We support the following meta programming constructs:
+
+| `$var id = exp` | Defines a named constant value. `$id` is valid util the end of the current meta lexical block. |
+|:----------------|:-----------------------------------------------------------------------------------------------|
+| `$range id exp..exp` | Sets the range of an iteration variable, which can be reused in multiple loops later. |
+| `$for id sep [[ code ]]` | Iteration. The range of `id` must have been defined earlier. `$id` is valid in `code`. |
+| `$($)` | Generates a single `$` character. |
+| `$id` | Value of the named constant or iteration variable. |
+| `$(exp)` | Value of the expression. |
+| `$if exp [[ code ]] else_branch` | Conditional. |
+| `[[ code ]]` | Meta lexical block. |
+| `cpp_code` | Raw C++ code. |
+| `$$ comment` | Meta comment. |
+
+**Note:** To give the user some freedom in formatting the Pump source
+code, Pump ignores a new-line character if it's right after `$for foo`
+or next to `[[` or `]]`. Without this rule you'll often be forced to write
+very long lines to get the desired output. Therefore sometimes you may
+need to insert an extra new-line in such places for a new-line to show
+up in your output.
+
+## Grammar ##
+
+```
+code ::= atomic_code*
+atomic_code ::= $var id = exp
+ | $var id = [[ code ]]
+ | $range id exp..exp
+ | $for id sep [[ code ]]
+ | $($)
+ | $id
+ | $(exp)
+ | $if exp [[ code ]] else_branch
+ | [[ code ]]
+ | cpp_code
+sep ::= cpp_code | empty_string
+else_branch ::= $else [[ code ]]
+ | $elif exp [[ code ]] else_branch
+ | empty_string
+exp ::= simple_expression_in_Python_syntax
+```
+
+## Code ##
+
+You can find the source code of Pump in [scripts/pump.py](../scripts/pump.py). It is still
+very unpolished and lacks automated tests, although it has been
+successfully used many times. If you find a chance to use it in your
+project, please let us know what you think! We also welcome help on
+improving Pump.
+
+## Real Examples ##
+
+You can find real-world applications of Pump in [Google Test](https://github.com/google/googletest/tree/master/googletest) and [Google Mock](https://github.com/google/googletest/tree/master/googlemock). The source file `foo.h.pump` generates `foo.h`.
+
+## Tips ##
+
+ * If a meta variable is followed by a letter or digit, you can separate them using `[[]]`, which inserts an empty string. For example `Foo$j[[]]Helper` generate `Foo1Helper` when `j` is 1.
+ * To avoid extra-long Pump source lines, you can break a line anywhere you want by inserting `[[]]` followed by a new line. Since any new-line character next to `[[` or `]]` is ignored, the generated code won't contain this new line.

+
+This guide will explain how to use the Google Testing Framework in your Xcode projects on Mac OS X. This tutorial begins by quickly explaining what to do for experienced users. After the quick start, the guide goes provides additional explanation about each step.
+
+# Quick Start #
+
+Here is the quick guide for using Google Test in your Xcode project.
+
+ 1. Download the source from the [website](http://code.google.com/p/googletest) using this command: `svn checkout http://googletest.googlecode.com/svn/trunk/ googletest-read-only`.
+ 1. Open up the `gtest.xcodeproj` in the `googletest-read-only/xcode/` directory and build the gtest.framework.
+ 1. Create a new "Shell Tool" target in your Xcode project called something like "UnitTests".
+ 1. Add the gtest.framework to your project and add it to the "Link Binary with Libraries" build phase of "UnitTests".
+ 1. Add your unit test source code to the "Compile Sources" build phase of "UnitTests".
+ 1. Edit the "UnitTests" executable and add an environment variable named "DYLD\_FRAMEWORK\_PATH" with a value equal to the path to the framework containing the gtest.framework relative to the compiled executable.
+ 1. Build and Go.
+
+The following sections further explain each of the steps listed above in depth, describing in more detail how to complete it including some variations.
+
+# Get the Source #
+
+Currently, the gtest.framework discussed here isn't available in a tagged release of Google Test, it is only available in the trunk. As explained at the Google Test [site](http://code.google.com/p/googletest/source/checkout">svn), you can get the code from anonymous SVN with this command:
+
+```
+svn checkout http://googletest.googlecode.com/svn/trunk/ googletest-read-only
+```
+
+Alternatively, if you are working with Subversion in your own code base, you can add Google Test as an external dependency to your own Subversion repository. By following this approach, everyone that checks out your svn repository will also receive a copy of Google Test (a specific version, if you wish) without having to check it out explicitly. This makes the set up of your project simpler and reduces the copied code in the repository.
+
+To use `svn:externals`, decide where you would like to have the external source reside. You might choose to put the external source inside the trunk, because you want it to be part of the branch when you make a release. However, keeping it outside the trunk in a version-tagged directory called something like `third-party/googletest/1.0.1`, is another option. Once the location is established, use `svn propedit svn:externals _directory_` to set the svn:externals property on a directory in your repository. This directory won't contain the code, but be its versioned parent directory.
+
+The command `svn propedit` will bring up your Subversion editor, making editing the long, (potentially multi-line) property simpler. This same method can be used to check out a tagged branch, by using the appropriate URL (e.g. `http://googletest.googlecode.com/svn/tags/release-1.0.1`). Additionally, the svn:externals property allows the specification of a particular revision of the trunk with the `-r_##_` option (e.g. `externals/src/googletest -r60 http://googletest.googlecode.com/svn/trunk`).
+
+Here is an example of using the svn:externals properties on a trunk (read via `svn propget`) of a project. This value checks out a copy of Google Test into the `trunk/externals/src/googletest/` directory.
+
+```
+[Computer:svn] user$ svn propget svn:externals trunk
+externals/src/googletest http://googletest.googlecode.com/svn/trunk
+```
+
+# Add the Framework to Your Project #
+
+The next step is to build and add the gtest.framework to your own project. This guide describes two common ways below.
+
+ * **Option 1** --- The simplest way to add Google Test to your own project, is to open gtest.xcodeproj (found in the xcode/ directory of the Google Test trunk) and build the framework manually. Then, add the built framework into your project using the "Add->Existing Framework..." from the context menu or "Project->Add..." from the main menu. The gtest.framework is relocatable and contains the headers and object code that you'll need to make tests. This method requires rebuilding every time you upgrade Google Test in your project.
+ * **Option 2** --- If you are going to be living off the trunk of Google Test, incorporating its latest features into your unit tests (or are a Google Test developer yourself). You'll want to rebuild the framework every time the source updates. to do this, you'll need to add the gtest.xcodeproj file, not the framework itself, to your own Xcode project. Then, from the build products that are revealed by the project's disclosure triangle, you can find the gtest.framework, which can be added to your targets (discussed below).
+
+# Make a Test Target #
+
+To start writing tests, make a new "Shell Tool" target. This target template is available under BSD, Cocoa, or Carbon. Add your unit test source code to the "Compile Sources" build phase of the target.
+
+Next, you'll want to add gtest.framework in two different ways, depending upon which option you chose above.
+
+ * **Option 1** --- During compilation, Xcode will need to know that you are linking against the gtest.framework. Add the gtest.framework to the "Link Binary with Libraries" build phase of your test target. This will include the Google Test headers in your header search path, and will tell the linker where to find the library.
+ * **Option 2** --- If your working out of the trunk, you'll also want to add gtest.framework to your "Link Binary with Libraries" build phase of your test target. In addition, you'll want to add the gtest.framework as a dependency to your unit test target. This way, Xcode will make sure that gtest.framework is up to date, every time your build your target. Finally, if you don't share build directories with Google Test, you'll have to copy the gtest.framework into your own build products directory using a "Run Script" build phase.
+
+# Set Up the Executable Run Environment #
+
+Since the unit test executable is a shell tool, it doesn't have a bundle with a `Contents/Frameworks` directory, in which to place gtest.framework. Instead, the dynamic linker must be told at runtime to search for the framework in another location. This can be accomplished by setting the "DYLD\_FRAMEWORK\_PATH" environment variable in the "Edit Active Executable ..." Arguments tab, under "Variables to be set in the environment:". The path for this value is the path (relative or absolute) of the directory containing the gtest.framework.
+
+If you haven't set up the DYLD\_FRAMEWORK\_PATH, correctly, you might get a message like this:
+
+```
+[Session started at 2008-08-15 06:23:57 -0600.]
+ dyld: Library not loaded: @loader_path/../Frameworks/gtest.framework/Versions/A/gtest
+ Referenced from: /Users/username/Documents/Sandbox/gtestSample/build/Debug/WidgetFrameworkTest
+ Reason: image not found
+```
+
+To correct this problem, go to to the directory containing the executable named in "Referenced from:" value in the error message above. Then, with the terminal in this location, find the relative path to the directory containing the gtest.framework. That is the value you'll need to set as the DYLD\_FRAMEWORK\_PATH.
+
+# Build and Go #
+
+Now, when you click "Build and Go", the test will be executed. Dumping out something like this:
+
+```
+[Session started at 2008-08-06 06:36:13 -0600.]
+[==========] Running 2 tests from 1 test case.
+[----------] Global test environment set-up.
+[----------] 2 tests from WidgetInitializerTest
+[ RUN ] WidgetInitializerTest.TestConstructor
+[ OK ] WidgetInitializerTest.TestConstructor
+[ RUN ] WidgetInitializerTest.TestConversion
+[ OK ] WidgetInitializerTest.TestConversion
+[----------] Global test environment tear-down
+[==========] 2 tests from 1 test case ran.
+[ PASSED ] 2 tests.
+
+The Debugger has exited with status 0.
+```
+
+# Summary #
+
+Unit testing is a valuable way to ensure your data model stays valid even during rapid development or refactoring. The Google Testing Framework is a great unit testing framework for C and C++ which integrates well with an Xcode development environment.

+// Here's what happens when an ASSERT_DEATH* or EXPECT_DEATH* is

+//
+// 1. It generates a warning if there is more than one active
+// thread. This is because it's safe to fork() or clone() only
+// when there is a single thread.
+//
+// 2. The parent process clone()s a sub-process and runs the death
+// test in it; the sub-process exits with code 0 at the end of the
+// death test, if it hasn't exited already.
+//
+// 3. The parent process waits for the sub-process to terminate.
+//
+// 4. The parent process checks the exit code and error message of
+// the sub-process.
+//
+// Examples:
+//
+// ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number");
+// for (int i = 0; i < 5; i++) {
+// EXPECT_DEATH(server.ProcessRequest(i),
+// "Invalid request .* in ProcessRequest()")
+// << "Failed to die on request " << i;
+// }
+//
+// ASSERT_EXIT(server.ExitNow(), ::testing::ExitedWithCode(0), "Exiting");
+//
+// bool KilledBySIGHUP(int exit_code) {
+// return WIFSIGNALED(exit_code) && WTERMSIG(exit_code) == SIGHUP;
+// }
+//
+// ASSERT_EXIT(client.HangUpServer(), KilledBySIGHUP, "Hanging up!");
+//
+// On the regular expressions used in death tests:
+//
+// On POSIX-compliant systems (*nix), we use the <regex.h> library,
+// which uses the POSIX extended regex syntax.
+//
+// On other platforms (e.g. Windows or Mac), we only support a simple regex
+// syntax implemented as part of Google Test. This limited
+// implementation should be enough most of the time when writing
+// death tests; though it lacks many features you can find in PCRE
+// or POSIX extended regex syntax. For example, we don't support
+// union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and
+// repetition count ("x{5,7}"), among others.
+//
+// Below is the syntax that we do support. We chose it to be a
+// subset of both PCRE and POSIX extended regex, so it's easy to
+// learn wherever you come from. In the following: 'A' denotes a
+// literal character, period (.), or a single \\ escape sequence;
+// 'x' and 'y' denote regular expressions; 'm' and 'n' are for
+// natural numbers.
+//
+// c matches any literal character c
+// \\d matches any decimal digit
+// \\D matches any character that's not a decimal digit
+// \\f matches \f
+// \\n matches \n
+// \\r matches \r
+// \\s matches any ASCII whitespace, including \n
+// \\S matches any character that's not a whitespace
+// \\t matches \t

+// Known caveats:
+//
+// A "threadsafe" style death test obtains the path to the test
+// program from argv[0] and re-executes it in the sub-process. For
+// simplicity, the current implementation doesn't search the PATH
+// when launching the sub-process. This means that the user must
+// invoke the test program via a path that contains at least one
+// path separator (e.g. path/to/foo_test and
+// /absolute/path/to/bar_test are fine, but foo_test is not). This
+// is rarely a problem as people usually don't put the test binary
+// directory in PATH.

+// This macro is used for implementing macros such as

+// death tests are not supported. Those macros must compile on such systems
+// iff EXPECT_DEATH and ASSERT_DEATH compile with the same parameters on
+// systems that support death tests. This allows one to write such a macro
+// on a system that does not support death tests and be sure that it will
+// compile on a death-test supporting system. It is exposed publicly so that
+// systems that have death-tests with stricter requirements than
+// GTEST_HAS_DEATH_TEST can write their own equivalent of
+// EXPECT_DEATH_IF_SUPPORTED and ASSERT_DEATH_IF_SUPPORTED.
+//
+// Parameters:
+// statement - A statement that a macro such as EXPECT_DEATH would test
+// for program termination. This macro has to make sure this
+// statement is compiled but not executed, to ensure that
+// EXPECT_DEATH_IF_SUPPORTED compiles with a certain
+// parameter iff EXPECT_DEATH compiles with it.
+// regex - A regex that a macro such as EXPECT_DEATH would use to test
+// the output of statement. This parameter has to be
+// compiled but not evaluated by this macro, to ensure that
+// this macro only accepts expressions that a macro such as
+// EXPECT_DEATH would accept.
+// terminator - Must be an empty statement for EXPECT_DEATH_IF_SUPPORTED
+// and a return statement for ASSERT_DEATH_IF_SUPPORTED.
+// This ensures that ASSERT_DEATH_IF_SUPPORTED will not
+// compile inside functions where ASSERT_DEATH doesn't
+// compile.
+//
+// The branch that has an always false condition is used to ensure that
+// statement and regex are compiled (and thus syntactically correct) but
+// never executed. The unreachable code macro protects the terminator
+// statement from generating an 'unreachable code' warning in case
+// statement unconditionally returns or throws. The Message constructor at
+// the end allows the syntax of streaming additional messages into the

+
+#if 0
+
+// To write value-parameterized tests, first you should define a fixture
+// class. It is usually derived from testing::TestWithParam<T> (see below for
+// another inheritance scheme that's sometimes useful in more complicated
+// class hierarchies), where the type of your parameter values.
+// TestWithParam<T> is itself derived from testing::Test. T can be any
+// copyable type. If it's a raw pointer, you are responsible for managing the
+// lifespan of the pointed values.
+
+class FooTest : public ::testing::TestWithParam<const char*> {
+ // You can implement all the usual class fixture members here.
+};
+
+// Then, use the TEST_P macro to define as many parameterized tests
+// for this fixture as you want. The _P suffix is for "parameterized"
+// or "pattern", whichever you prefer to think.
+
+TEST_P(FooTest, DoesBlah) {
+ // Inside a test, access the test parameter with the GetParam() method
+ // of the TestWithParam<T> class:
+ EXPECT_TRUE(foo.Blah(GetParam()));
+ ...
+}
+
+TEST_P(FooTest, HasBlahBlah) {
+ ...
+}
+
+// Finally, you can use INSTANTIATE_TEST_CASE_P to instantiate the test
+// case with any set of parameters you want. Google Test defines a number
+// of functions for generating test parameters. They return what we call
+// (surprise!) parameter generators. Here is a summary of them, which
+// are all in the testing namespace:
+//
+//
+// Range(begin, end [, step]) - Yields values {begin, begin+step,
+// begin+step+step, ...}. The values do not
+// include end. step defaults to 1.
+// Values(v1, v2, ..., vN) - Yields values {v1, v2, ..., vN}.
+// ValuesIn(container) - Yields values from a C-style array, an STL
+// ValuesIn(begin,end) container, or an iterator range [begin, end).
+// Bool() - Yields sequence {false, true}.
+// Combine(g1, g2, ..., gN) - Yields all combinations (the Cartesian product
+// for the math savvy) of the values generated
+// by the N generators.
+//
+// For more details, see comments at the definitions of these functions below
+// in this file.
+//
+// The following statement will instantiate tests from the FooTest test case
+// each with parameter values "meeny", "miny", and "moe".
+
+INSTANTIATE_TEST_CASE_P(InstantiationName,
+ FooTest,
+ Values("meeny", "miny", "moe"));
+
+// To distinguish different instances of the pattern, (yes, you
+// can instantiate it more then once) the first argument to the
+// INSTANTIATE_TEST_CASE_P macro is a prefix that will be added to the
+// actual test case name. Remember to pick unique prefixes for different
+// instantiations. The tests from the instantiation above will have
+// these names:
+//
+// * InstantiationName/FooTest.DoesBlah/0 for "meeny"

+// * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
+// * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
+//
+// You can use these names in --gtest_filter.
+//
+// This statement will instantiate all tests from FooTest again, each
+// with parameter values "cat" and "dog":
+

+// * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
+// * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
+//
+// Please note that INSTANTIATE_TEST_CASE_P will instantiate all tests
+// in the given test case, whether their definitions come before or
+// AFTER the INSTANTIATE_TEST_CASE_P statement.
+//
+// Please also note that generator expressions (including parameters to the
+// generators) are evaluated in InitGoogleTest(), after main() has started.
+// This allows the user on one hand, to adjust generator parameters in order
+// to dynamically determine a set of tests to run and on the other hand,
+// give the user a chance to inspect the generated tests with Google Test
+// reflection API before RUN_ALL_TESTS() is executed.
+//
+// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
+// for more examples.
+//
+// In the future, we plan to publish the API for defining new parameter
+// generators. But for now this interface remains part of the internal
+// implementation and is subject to change.
+//
+//
+// A parameterized test fixture must be derived from testing::Test and from
+// testing::WithParamInterface<T>, where T is the type of the parameter
+// values. Inheriting from TestWithParam<T> satisfies that requirement because
+// TestWithParam<T> inherits from both Test and WithParamInterface. In more
+// complicated hierarchies, however, it is occasionally useful to inherit
+// separately from Test and WithParamInterface. For example:
+
+class BaseTest : public ::testing::Test {
+ // You can inherit all the usual members for a non-parameterized test
+ // fixture here.
+};
+
+class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> {
+ // The usual test fixture members go here too.
+};
+
+TEST_F(BaseTest, HasFoo) {
+ // This is an ordinary non-parameterized test.
+}

+TEST_P(DerivedTest, DoesBlah) {
+ // GetParam works just the same here as if you inherit from TestWithParam.

+// Functions producing parameter generators.
+//
+// Google Test uses these generators to produce parameters for value-
+// parameterized tests. When a parameterized test case is instantiated
+// with a particular generator, Google Test creates and runs tests
+// for each element in the sequence produced by the generator.
+//
+// In the following sample, tests from test case FooTest are instantiated
+// each three times with parameter values 3, 5, and 8:
+//
+// class FooTest : public TestWithParam<int> { ... };
+//
+// TEST_P(FooTest, TestThis) {
+// }
+// TEST_P(FooTest, TestThat) {
+// }
+// INSTANTIATE_TEST_CASE_P(TestSequence, FooTest, Values(3, 5, 8));
+//
+
+// Range() returns generators providing sequences of values in a range.
+//
+// Synopsis:
+// Range(start, end)
+// - returns a generator producing a sequence of values {start, start+1,
+// start+2, ..., }.
+// Range(start, end, step)
+// - returns a generator producing a sequence of values {start, start+step,
+// start+step+step, ..., }.
+// Notes:
+// * The generated sequences never include end. For example, Range(1, 5)
+// returns a generator producing a sequence {1, 2, 3, 4}. Range(1, 9, 2)
+// returns a generator producing {1, 3, 5, 7}.
+// * start and end must have the same type. That type may be any integral or
+// floating-point type or a user defined type satisfying these conditions:
+// * It must be assignable (have operator=() defined).
+// * It must have operator+() (operator+(int-compatible type) for
+// two-operand version).
+// * It must have operator<() defined.
+// Elements in the resulting sequences will also have that type.
+// * Condition start < end must be satisfied in order for resulting sequences
+// to contain any elements.

+// Value-parameterized tests allow you to test your code with different
+// parameters without writing multiple copies of the same test.
+//
+// Here is how you use value-parameterized tests:
+
+#if 0
+
+// To write value-parameterized tests, first you should define a fixture
+// class. It is usually derived from testing::TestWithParam<T> (see below for
+// another inheritance scheme that's sometimes useful in more complicated
+// class hierarchies), where the type of your parameter values.
+// TestWithParam<T> is itself derived from testing::Test. T can be any
+// copyable type. If it's a raw pointer, you are responsible for managing the
+// lifespan of the pointed values.
+
+class FooTest : public ::testing::TestWithParam<const char*> {
+ // You can implement all the usual class fixture members here.
+};
+
+// Then, use the TEST_P macro to define as many parameterized tests
+// for this fixture as you want. The _P suffix is for "parameterized"
+// or "pattern", whichever you prefer to think.
+
+TEST_P(FooTest, DoesBlah) {
+ // Inside a test, access the test parameter with the GetParam() method
+ // of the TestWithParam<T> class:
+ EXPECT_TRUE(foo.Blah(GetParam()));
+ ...
+}
+
+TEST_P(FooTest, HasBlahBlah) {
+ ...
+}
+
+// Finally, you can use INSTANTIATE_TEST_CASE_P to instantiate the test
+// case with any set of parameters you want. Google Test defines a number
+// of functions for generating test parameters. They return what we call
+// (surprise!) parameter generators. Here is a summary of them, which
+// are all in the testing namespace:
+//
+//
+// Range(begin, end [, step]) - Yields values {begin, begin+step,
+// begin+step+step, ...}. The values do not
+// include end. step defaults to 1.
+// Values(v1, v2, ..., vN) - Yields values {v1, v2, ..., vN}.
+// ValuesIn(container) - Yields values from a C-style array, an STL
+// ValuesIn(begin,end) container, or an iterator range [begin, end).
+// Bool() - Yields sequence {false, true}.
+// Combine(g1, g2, ..., gN) - Yields all combinations (the Cartesian product
+// for the math savvy) of the values generated
+// by the N generators.
+//
+// For more details, see comments at the definitions of these functions below
+// in this file.
+//
+// The following statement will instantiate tests from the FooTest test case
+// each with parameter values "meeny", "miny", and "moe".
+
+INSTANTIATE_TEST_CASE_P(InstantiationName,
+ FooTest,
+ Values("meeny", "miny", "moe"));
+
+// To distinguish different instances of the pattern, (yes, you
+// can instantiate it more then once) the first argument to the
+// INSTANTIATE_TEST_CASE_P macro is a prefix that will be added to the
+// actual test case name. Remember to pick unique prefixes for different
+// instantiations. The tests from the instantiation above will have
+// these names:
+//
+// * InstantiationName/FooTest.DoesBlah/0 for "meeny"
+// * InstantiationName/FooTest.DoesBlah/1 for "miny"

+// * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
+// * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
+//
+// You can use these names in --gtest_filter.
+//
+// This statement will instantiate all tests from FooTest again, each
+// with parameter values "cat" and "dog":

+// * AnotherInstantiationName/FooTest.DoesBlah/1 for "dog"
+// * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
+// * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
+//
+// Please note that INSTANTIATE_TEST_CASE_P will instantiate all tests
+// in the given test case, whether their definitions come before or
+// AFTER the INSTANTIATE_TEST_CASE_P statement.
+//
+// Please also note that generator expressions (including parameters to the
+// generators) are evaluated in InitGoogleTest(), after main() has started.
+// This allows the user on one hand, to adjust generator parameters in order
+// to dynamically determine a set of tests to run and on the other hand,
+// give the user a chance to inspect the generated tests with Google Test
+// reflection API before RUN_ALL_TESTS() is executed.
+//
+// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
+// for more examples.
+//
+// In the future, we plan to publish the API for defining new parameter
+// generators. But for now this interface remains part of the internal
+// implementation and is subject to change.
+//
+//
+// A parameterized test fixture must be derived from testing::Test and from

+// values. Inheriting from TestWithParam<T> satisfies that requirement because
+// TestWithParam<T> inherits from both Test and WithParamInterface. In more
+// complicated hierarchies, however, it is occasionally useful to inherit
+// separately from Test and WithParamInterface. For example:
+
+class BaseTest : public ::testing::Test {
+ // You can inherit all the usual members for a non-parameterized test
+ // fixture here.
+};
+
+class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> {

+// This file implements a universal value printer that can print a
+// value of any type T:
+//
+// void ::testing::internal::UniversalPrinter<T>::Print(value, ostream_ptr);
+//
+// A user can teach this function how to print a class type T by
+// defining either operator<<() or PrintTo() in the namespace that
+// defines T. More specifically, the FIRST defined function in the
+// following list will be used (assuming T is defined in namespace
+// foo):
+//
+// 1. foo::PrintTo(const T&, ostream*)
+// 2. operator<<(ostream&, const T&) defined in either foo or the
+// global namespace.
+//
+// However if T is an STL-style container then it is printed element-wise
+// unless foo::PrintTo(const T&, ostream*) is defined. Note that
+// operator<<() is ignored for container types.
+//
+// If none of the above is defined, it will print the debug string of
+// the value if it is a protocol buffer, or print the raw bytes in the
+// value otherwise.
+//
+// To aid debugging: when T is a reference type, the address of the
+// value is also printed; when T is a (const) char pointer, both the
+// pointer value and the NUL-terminated string it points to are
+// printed.
+//
+// We also provide some convenient wrappers:
+//
+// // Prints a value to a string. For a (const or not) char
+// // pointer, the NUL-terminated string (but not the pointer) is
+// // printed.
+// std::string ::testing::PrintToString(const T& value);
+//
+// // Prints a value tersely: for a reference type, the referenced
+// // value (but not the address) is printed; for a (const or not) char
+// // pointer, the NUL-terminated string (but not the pointer) is
+// // printed.
+// void ::testing::internal::UniversalTersePrint(const T& value, ostream*);
+//
+// // Prints value using the type inferred by the compiler. The difference
+// // from UniversalTersePrint() is that this function prints both the
+// // pointer and the NUL-terminated string for a (const or not) char pointer.
+// void ::testing::internal::UniversalPrint(const T& value, ostream*);
+//
+// // Prints the fields of a tuple tersely to a string vector, one
+// // element for each field. Tuple support must be enabled in
+// // gtest-port.h.
+// std::vector<string> UniversalTersePrintTupleFieldsToStrings(
+// const Tuple& value);
+//
+// Known limitation:
+//
+// The print primitives print the elements of an STL-style container
+// using the compiler-inferred type of *iter where iter is a
+// const_iterator of the container. When const_iterator is an input
+// iterator but not a forward iterator, this inferred type may not
+// match value_type, and the print output may be incorrect. In
+// practice, this is rarely a problem as for most containers
+// const_iterator is a forward iterator. We'll fix this if there's an
+// actual need for it. Note that this fix cannot rely on value_type
+// being defined as many user-defined container types don't have
+// value_type.

+// repeated for each type in the list. The typedef is necessary for
+// the macro to parse correctly.
+typedef testing::Types<char, int, unsigned int> MyTypes;
+TYPED_TEST_CASE(FooTest, MyTypes);
+
+// If the type list contains only one type, you can write that type
+// directly without Types<...>:
+// TYPED_TEST_CASE(FooTest, int);
+
+// Then, use TYPED_TEST() instead of TEST_F() to define as many typed
+// tests for this test case as you want.
+TYPED_TEST(FooTest, DoesBlah) {

+ // Since we are inside a derived class template, C++ requires use to
+ // visit the members of FooTest via 'this'.

+ // prefix.
+ n += TestFixture::shared_;
+
+ // To refer to typedefs in the fixture, add the "typename
+ // TestFixture::" prefix.

+#endif // 0
+
+// Type-parameterized tests are abstract test patterns parameterized
+// by a type. Compared with typed tests, type-parameterized tests
+// allow you to define the test pattern without knowing what the type
+// parameters are. The defined pattern can be instantiated with
+// different types any number of times, in any number of translation
+// units.
+//
+// If you are designing an interface or concept, you can define a
+// suite of type-parameterized tests to verify properties that any
+// valid implementation of the interface/concept should have. Then,
+// each implementation can easily instantiate the test suite to verify
+// that it conforms to the requirements, without having to write
+// similar tests repeatedly. Here's an example:
+
+#if 0
+
+// First, define a fixture class template. It should be parameterized
+// by a type. Remember to derive it from testing::Test.
+template <typename T>
+class FooTest : public testing::Test {
+ ...
+};

+// Next, declare that you will define a type-parameterized test case
+// (the _P suffix is for "parameterized" or "pattern", whichever you
+// prefer):
+TYPED_TEST_CASE_P(FooTest);

+// Then, use TYPED_TEST_P() to define as many type-parameterized tests
+// for this type-parameterized test case as you want.

+ TypeParam n = 0;
+ ...
+}
+

+// you can instantiate them. The first argument of the macro is the
+// test case name; the rest are the names of the tests in this test
+// case.
+REGISTER_TYPED_TEST_CASE_P(FooTest,
+ DoesBlah, HasPropertyA);
+
+// Finally, you are free to instantiate the pattern with the types you
+// want. If you put the above code in a header file, you can #include
+// it in multiple C++ source files and instantiate it multiple times.

+// A class for indicating whether an assertion was successful. When
+// the assertion wasn't successful, the AssertionResult object
+// remembers a non-empty message that describes how it failed.
+//
+// To create an instance of this class, use one of the factory functions
+// (AssertionSuccess() and AssertionFailure()).
+//
+// This class is useful for two purposes:
+// 1. Defining predicate functions to be used with Boolean test assertions
+// EXPECT_TRUE/EXPECT_FALSE and their ASSERT_ counterparts
+// 2. Defining predicate-format functions to be
+// used with predicate assertions (ASSERT_PRED_FORMAT*, etc).
+//
+// For example, if you define IsEven predicate:
+//
+// testing::AssertionResult IsEven(int n) {
+// if ((n % 2) == 0)
+// return testing::AssertionSuccess();
+// else
+// return testing::AssertionFailure() << n << " is odd";
+// }
+//
+// Then the failed expectation EXPECT_TRUE(IsEven(Fib(5)))
+// will print the message
+//
+// Value of: IsEven(Fib(5))
+// Actual: false (5 is odd)
+// Expected: true
+//
+// instead of a more opaque
+//
+// Value of: IsEven(Fib(5))
+// Actual: false
+// Expected: true
+//
+// in case IsEven is a simple Boolean predicate.
+//
+// If you expect your predicate to be reused and want to support informative
+// messages in EXPECT_FALSE and ASSERT_FALSE (negative assertions show up
+// about half as often as positive ones in our tests), supply messages for
+// both success and failure cases:
+//
+// testing::AssertionResult IsEven(int n) {
+// if ((n % 2) == 0)
+// return testing::AssertionSuccess() << n << " is even";
+// else
+// return testing::AssertionFailure() << n << " is odd";
+// }
+//
+// Then a statement EXPECT_FALSE(IsEven(Fib(6))) will print
+//
+// Value of: IsEven(Fib(6))
+// Actual: true (8 is even)
+// Expected: false
+//
+// NB: Predicates that support negative Boolean assertions have reduced
+// performance in positive ones so be careful not to use them in tests
+// that have lots (tens of thousands) of positive Boolean assertions.
+//
+// To use this class with EXPECT_PRED_FORMAT assertions such as:
+//
+// // Verifies that Foo() returns an even number.
+// EXPECT_PRED_FORMAT1(IsEven, Foo());
+//
+// you need to define:
+//
+// testing::AssertionResult IsEven(const char* expr, int n) {
+// if ((n % 2) == 0)
+// return testing::AssertionSuccess();
+// else
+// return testing::AssertionFailure()
+// << "Expected: " << expr << " is even\n Actual: it's " << n;
+// }
+//
+// If Foo() returns 5, you will see the following message:
+//
+// Expected: Foo() is even
+// Actual: it's 5

+// A "smart" pointer type with reference tracking. Every pointer to a
+// particular object is kept on a circular linked list. When the last pointer
+// to an object is destroyed or reassigned, the object is deleted.
+//
+// Used properly, this deletes the object when the last reference goes away.
+// There are several caveats:
+// - Like all reference counting schemes, cycles lead to leaks.
+// - Each smart pointer is actually two pointers (8 bytes instead of 4).
+// - Every time a pointer is assigned, the entire list of pointers to that
+// object is traversed. This class is therefore NOT SUITABLE when there
+// will often be more than two or three pointers to a particular object.
+// - References are only tracked as long as linked_ptr<> objects are copied.
+// If a linked_ptr<> is converted to a raw pointer and back, BAD THINGS
+// will happen (double deletion).
+//
+// A good use of this class is storing object references in STL containers.
+// You can safely put linked_ptr<> in a vector<>.
+// Other uses may not be as good.
+//
+// Note: If you use an incomplete type with linked_ptr<>, the class
+// *containing* linked_ptr<> must have a constructor and destructor (even
+// if they do nothing!).
+//
+// Bill Gibbons suggested we use something like this.
+//
+// Thread Safety:
+// Unlike other linked_ptr implementations, in this implementation
+// a linked_ptr object is thread-safe in the sense that:
+// - it's safe to copy linked_ptr objects concurrently,
+// - it's safe to copy *from* a linked_ptr and read its underlying
+// raw pointer (e.g. via get()) concurrently, and
+// - it's safe to write to two linked_ptrs that point to the same
+// shared object concurrently.
+// TODO(wan@google.com): rename this to safe_linked_ptr to avoid
+// confusion with normal linked_ptr.

+
+// Environment-describing macros
+// -----------------------------
+//
+// Google Test can be used in many different environments. Macros in
+// this section tell Google Test what kind of environment it is being
+// used in, such that Google Test can provide environment-specific
+// features and implementations.
+//
+// Google Test tries to automatically detect the properties of its
+// environment, so users usually don't need to worry about these
+// macros. However, the automatic detection is not perfect.
+// Sometimes it's necessary for a user to define some of the following
+// macros in the build script to override Google Test's decisions.
+//
+// If the user doesn't define a macro in the list, Google Test will
+// provide a default definition. After this header is #included, all
+// macros in this list will be defined to either 1 or 0.
+//
+// Notes to maintainers:
+// - Each macro here is a user-tweakable knob; do not grow the list
+// lightly.
+// - Use #if to key off these macros. Don't use #ifdef or "#if
+// defined(...)", which will not work as these macros are ALWAYS
+// defined.
+//
+// GTEST_HAS_CLONE - Define it to 1/0 to indicate that clone(2)
+// is/isn't available.
+// GTEST_HAS_EXCEPTIONS - Define it to 1/0 to indicate that exceptions
+// are enabled.
+// GTEST_HAS_GLOBAL_STRING - Define it to 1/0 to indicate that ::string
+// is/isn't available
+// GTEST_HAS_GLOBAL_WSTRING - Define it to 1/0 to indicate that ::wstring
+// is/isn't available
+// GTEST_HAS_POSIX_RE - Define it to 1/0 to indicate that POSIX regular
+// expressions are/aren't available.
+// GTEST_HAS_PTHREAD - Define it to 1/0 to indicate that <pthread.h>
+// is/isn't available.
+// GTEST_HAS_RTTI - Define it to 1/0 to indicate that RTTI is/isn't
+// enabled.
+// GTEST_HAS_STD_WSTRING - Define it to 1/0 to indicate that
+// std::wstring does/doesn't work (Google Test can
+// be used where std::wstring is unavailable).
+// GTEST_HAS_TR1_TUPLE - Define it to 1/0 to indicate tr1::tuple
+// is/isn't available.
+// GTEST_HAS_SEH - Define it to 1/0 to indicate whether the
+// compiler supports Microsoft's "Structured
+// Exception Handling".
+// GTEST_HAS_STREAM_REDIRECTION
+// - Define it to 1/0 to indicate whether the
+// platform supports I/O stream redirection using
+// dup() and dup2().
+// GTEST_USE_OWN_TR1_TUPLE - Define it to 1/0 to indicate whether Google
+// Test's own tr1 tuple implementation should be
+// used. Unused when the user sets
+// GTEST_HAS_TR1_TUPLE to 0.
+// GTEST_LANG_CXX11 - Define it to 1/0 to indicate that Google Test
+// is building in C++11/C++98 mode.
+// GTEST_LINKED_AS_SHARED_LIBRARY
+// - Define to 1 when compiling tests that use
+// Google Test as a shared library (known as
+// DLL on Windows).
+// GTEST_CREATE_SHARED_LIBRARY
+// - Define to 1 when compiling Google Test itself
+// as a shared library.
+// GTEST_DEFAULT_DEATH_TEST_STYLE
+// - The default value of --gtest_death_test_style.
+// The legacy default has been "fast" in the open
+// source version since 2008. The recommended value
+// is "threadsafe", and can be set in
+// custom/gtest-port.h.
+
+// Platform-indicating macros
+// --------------------------
+//
+// Macros indicating the platform on which Google Test is being used
+// (a macro is defined to 1 if compiled on the given platform;
+// otherwise UNDEFINED -- it's never defined to 0.). Google Test
+// defines these macros automatically. Code outside Google Test MUST
+// NOT define them.
+//
+// GTEST_OS_AIX - IBM AIX
+// GTEST_OS_CYGWIN - Cygwin
+// GTEST_OS_FREEBSD - FreeBSD
+// GTEST_OS_FUCHSIA - Fuchsia
+// GTEST_OS_HPUX - HP-UX
+// GTEST_OS_LINUX - Linux
+// GTEST_OS_LINUX_ANDROID - Google Android
+// GTEST_OS_MAC - Mac OS X
+// GTEST_OS_IOS - iOS
+// GTEST_OS_NACL - Google Native Client (NaCl)
+// GTEST_OS_NETBSD - NetBSD
+// GTEST_OS_OPENBSD - OpenBSD
+// GTEST_OS_QNX - QNX
+// GTEST_OS_SOLARIS - Sun Solaris
+// GTEST_OS_SYMBIAN - Symbian
+// GTEST_OS_WINDOWS - Windows (Desktop, MinGW, or Mobile)
+// GTEST_OS_WINDOWS_DESKTOP - Windows Desktop
+// GTEST_OS_WINDOWS_MINGW - MinGW
+// GTEST_OS_WINDOWS_MOBILE - Windows Mobile
+// GTEST_OS_WINDOWS_PHONE - Windows Phone
+// GTEST_OS_WINDOWS_RT - Windows Store App/WinRT
+// GTEST_OS_ZOS - z/OS
+//
+// Among the platforms, Cygwin, Linux, Max OS X, and Windows have the
+// most stable support. Since core members of the Google Test project
+// don't have access to other platforms, support for them may be less
+// stable. If you notice any problems on your platform, please notify
+// googletestframework@googlegroups.com (patches for fixing them are
+// even more welcome!).
+//
+// It is possible that none of the GTEST_OS_* macros are defined.
+
+// Feature-indicating macros
+// -------------------------
+//
+// Macros indicating which Google Test features are available (a macro
+// is defined to 1 if the corresponding feature is supported;
+// otherwise UNDEFINED -- it's never defined to 0.). Google Test
+// defines these macros automatically. Code outside Google Test MUST
+// NOT define them.
+//
+// These macros are public so that portable tests can be written.
+// Such tests typically surround code using a feature with an #if
+// which controls that code. For example:
+//
+// #if GTEST_HAS_DEATH_TEST
+// EXPECT_DEATH(DoSomethingDeadly());
+// #endif
+//
+// GTEST_HAS_COMBINE - the Combine() function (for value-parameterized
+// tests)
+// GTEST_HAS_DEATH_TEST - death tests
+// GTEST_HAS_TYPED_TEST - typed tests
+// GTEST_HAS_TYPED_TEST_P - type-parameterized tests
+// GTEST_IS_THREADSAFE - Google Test is thread-safe.
+// GTEST_USES_POSIX_RE - enhanced POSIX regex is used. Do not confuse with
+// GTEST_HAS_POSIX_RE (see above) which users can
+// define themselves.
+// GTEST_USES_SIMPLE_RE - our own simple regex is used;
+// the above RE\b(s) are mutually exclusive.
+// GTEST_CAN_COMPARE_NULL - accepts untyped NULL in EXPECT_EQ().
+
+// Misc public macros
+// ------------------
+//
+// GTEST_FLAG(flag_name) - references the variable corresponding to
+// the given Google Test flag.
+
+// Internal utilities
+// ------------------
+//
+// The following macros and utilities are for Google Test's INTERNAL
+// use only. Code outside Google Test MUST NOT USE THEM DIRECTLY.
+//
+// Macros for basic C++ coding:
+// GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning.
+// GTEST_ATTRIBUTE_UNUSED_ - declares that a class' instances or a
+// variable don't have to be used.
+// GTEST_DISALLOW_ASSIGN_ - disables operator=.
+// GTEST_DISALLOW_COPY_AND_ASSIGN_ - disables copy ctor and operator=.
+// GTEST_MUST_USE_RESULT_ - declares that a function's result must be used.
+// GTEST_INTENTIONAL_CONST_COND_PUSH_ - start code section where MSVC C4127 is
+// suppressed (constant conditional).
+// GTEST_INTENTIONAL_CONST_COND_POP_ - finish code section where MSVC C4127
+// is suppressed.
+//
+// C++11 feature wrappers:
+//
+// testing::internal::forward - portability wrapper for std::forward.
+// testing::internal::move - portability wrapper for std::move.
+//
+// Synchronization:
+// Mutex, MutexLock, ThreadLocal, GetThreadCount()
+// - synchronization primitives.
+//
+// Template meta programming:
+// is_pointer - as in TR1; needed on Symbian and IBM XL C/C++ only.
+// IteratorTraits - partial implementation of std::iterator_traits, which
+// is not available in libCstd when compiled with Sun C++.
+//
+// Smart pointers:
+// scoped_ptr - as in TR2.
+//
+// Regular expressions:
+// RE - a simple regular expression class using the POSIX
+// Extended Regular Expression syntax on UNIX-like platforms
+// or a reduced regular exception syntax on other
+// platforms, including Windows.
+// Logging:
+// GTEST_LOG_() - logs messages at the specified severity level.
+// LogToStderr() - directs all log messages to stderr.
+// FlushInfoLog() - flushes informational log messages.
+//
+// Stdout and stderr capturing:
+// CaptureStdout() - starts capturing stdout.
+// GetCapturedStdout() - stops capturing stdout and returns the captured
+// string.
+// CaptureStderr() - starts capturing stderr.
+// GetCapturedStderr() - stops capturing stderr and returns the captured
+// string.
+//
+// Integer types:
+// TypeWithSize - maps an integer to a int type.
+// Int32, UInt32, Int64, UInt64, TimeInMillis
+// - integers of known sizes.
+// BiggestInt - the biggest signed integer type.
+//
+// Command-line utilities:
+// GTEST_DECLARE_*() - declares a flag.
+// GTEST_DEFINE_*() - defines a flag.
+// GetInjectableArgvs() - returns the command line as a vector of strings.
+//
+// Environment variable utilities:
+// GetEnv() - gets the value of an environment variable.
+// BoolFromGTestEnv() - parses a bool environment variable.
+// Int32FromGTestEnv() - parses an Int32 environment variable.
+// StringFromGTestEnv() - parses a string environment variable.

+// elements (and thus is invalid) when the expression is false.
+//
+// - The simpler definition
+//
+// #define GTEST_COMPILE_ASSERT_(expr, msg) typedef char msg[(expr) ? 1 : -1]
+//
+// does not work, as gcc supports variable-length arrays whose sizes
+// are determined at run-time (this is gcc's extension and not part
+// of the C++ standard). As a result, gcc fails to reject the
+// following code with the simple definition:
+//
+// int foo;
+// GTEST_COMPILE_ASSERT_(foo, msg); // not supposed to compile as foo is
+// // not a compile-time constant.
+//
+// - By using the type CompileAssert<(bool(expr))>, we ensures that
+// expr is a compile-time constant. (Template arguments must be
+// determined at compile-time.)
+//
+// - The outter parentheses in CompileAssert<(bool(expr))> are necessary
+// to work around a bug in gcc 3.4.4 and 4.0.1. If we had written
+//
+// CompileAssert<bool(expr)>
+//
+// instead, these compilers will refuse to compile

+// template argument list.)
+//
+// - The array size is (bool(expr) ? 1 : -1), instead of simply
+//
+// ((expr) ? 1 : -1).

+dnl
+dnl @summary figure out how to build C programs using POSIX threads
+dnl
+dnl This macro figures out how to build C programs using POSIX threads.
+dnl It sets the PTHREAD_LIBS output variable to the threads library and
+dnl linker flags, and the PTHREAD_CFLAGS output variable to any special
+dnl C compiler flags that are needed. (The user can also force certain
+dnl compiler flags/libs to be tested by setting these environment
+dnl variables.)
+dnl
+dnl Also sets PTHREAD_CC to any special C compiler that is needed for
+dnl multi-threaded programs (defaults to the value of CC otherwise).
+dnl (This is necessary on AIX to use the special cc_r compiler alias.)
+dnl
+dnl NOTE: You are assumed to not only compile your program with these
+dnl flags, but also link it with them as well. e.g. you should link
+dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
+dnl $LIBS
+dnl
+dnl If you are only building threads programs, you may wish to use
+dnl these variables in your default LIBS, CFLAGS, and CC:
+dnl
+dnl LIBS="$PTHREAD_LIBS $LIBS"
+dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+dnl CC="$PTHREAD_CC"
+dnl
+dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
+dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
+dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+dnl
+dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
+dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to
+dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the
+dnl default action will define HAVE_PTHREAD.
+dnl
+dnl Please let the authors know if this macro fails on any platform, or
+dnl if you have any other suggestions or comments. This macro was based
+dnl on work by SGJ on autoconf scripts for FFTW (www.fftw.org) (with
+dnl help from M. Frigo), as well as ac_pthread and hb_pthread macros
+dnl posted by Alejandro Forero Cuervo to the autoconf macro repository.
+dnl We are also grateful for the helpful feedback of numerous users.

+// Author: wan@google.com (Zhanyong Wan)

+
+// This sample shows how to write a simple unit test for a function,
+// using Google C++ testing framework.
+//
+// Writing a unit test using Google C++ testing framework is easy as 1-2-3:
+
+
+// Step 1. Include necessary header files such that the stuff your
+// test logic needs is declared.
+//
+// Don't forget gtest.h, which declares the testing framework.
+
+#include <limits.h>
+#include "sample1.h"
+#include "gtest/gtest.h"
+namespace {
+
+// Step 2. Use the TEST macro to define your tests.
+//
+// TEST has two parameters: the test case name and the test name.
+// After using the macro, you should define your test logic between a
+// pair of braces. You can use a bunch of macros to indicate the
+// success or failure of a test. EXPECT_TRUE and EXPECT_EQ are
+// examples of such macros. For a complete list, see gtest.h.
+//
+// <TechnicalDetails>
+//
+// In Google Test, tests are grouped into test cases. This is how we
+// keep test code organized. You should put logically related tests
+// into the same test case.
+//
+// The test case name and the test name should both be valid C++
+// identifiers. And you should not use underscore (_) in the names.
+//
+// Google Test guarantees that each test you define is run exactly
+// once, but it makes no guarantee on the order the tests are
+// executed. Therefore, you should write your tests in such a way
+// that their results don't depend on their order.
+//
+// </TechnicalDetails>
+
+
+// Tests Factorial().
+
+// Tests factorial of negative numbers.
+TEST(FactorialTest, Negative) {
+ // This test is named "Negative", and belongs to the "FactorialTest"
+ // test case.
+ EXPECT_EQ(1, Factorial(-5));
+ EXPECT_EQ(1, Factorial(-1));
+ EXPECT_GT(Factorial(-10), 0);
+
+ // <TechnicalDetails>
+ //
+ // EXPECT_EQ(expected, actual) is the same as
+ //
+ // EXPECT_TRUE((expected) == (actual))
+ //
+ // except that it will print both the expected value and the actual
+ // value when the assertion fails. This is very helpful for
+ // debugging. Therefore in this case EXPECT_EQ is preferred.
+ //
+ // On the other hand, EXPECT_TRUE accepts any Boolean expression,
+ // and is thus more general.
+ //
+ // </TechnicalDetails>
+}
+
+// Tests factorial of 0.
+TEST(FactorialTest, Zero) {
+ EXPECT_EQ(1, Factorial(0));
+}
+

+ EXPECT_EQ(6, Factorial(3));

+}

+

+
+// Tests negative input.

+ // This test belongs to the IsPrimeTest test case.
+
+ EXPECT_FALSE(IsPrime(-1));
+ EXPECT_FALSE(IsPrime(-2));
+ EXPECT_FALSE(IsPrime(INT_MIN));

+
+// Tests some trivial cases.
+TEST(IsPrimeTest, Trivial) {
+ EXPECT_FALSE(IsPrime(0));

+TEST(IsPrimeTest, Positive) {
+ EXPECT_FALSE(IsPrime(4));
+ EXPECT_TRUE(IsPrime(5));
+ EXPECT_FALSE(IsPrime(6));
+ EXPECT_TRUE(IsPrime(23));
+}
+} // namespace
+
+// Step 3. Call RUN_ALL_TESTS() in main().
+//
+// We do this by linking in src/gtest_main.cc file, which consists of
+// a main() function which calls RUN_ALL_TESTS() for us.
+//
+// This runs all the tests you've defined, prints the result, and
+// returns 0 if successful, or 1 otherwise.
+//
+// Did you notice that we didn't register the tests? The
+// RUN_ALL_TESTS() macro magically knows about all the tests we
+// defined. Isn't this convenient?

+// In this example, we use a more advanced feature of Google Test called
+// test fixture.
+//
+// A test fixture is a place to hold objects and functions shared by
+// all tests in a test case. Using a test fixture avoids duplicating
+// the test code necessary to initialize and cleanup those common
+// objects for each test. It is also useful for defining sub-routines
+// that your tests need to invoke a lot.
+//
+// <TechnicalDetails>
+//
+// The tests share the test fixture in the sense of code sharing, not
+// data sharing. Each test is given its own fresh copy of the
+// fixture. You cannot expect the data modified by one test to be
+// passed on to another test, which is a bad idea.
+//
+// The reason for this design is that tests should be independent and
+// repeatable. In particular, a test should not fail as the result of
+// another test's failure. If one test depends on info produced by
+// another test, then the two tests should really be one big test.
+//
+// The macros for indicating the success/failure of a test
+// (EXPECT_TRUE, FAIL, etc) need to know what the current test is
+// (when Google Test prints the test result, it tells you which test
+// each failure belongs to). Technically, these macros invoke a
+// member function of the Test class. Therefore, you cannot use them
+// in a global function. That's why you should put test sub-routines

+// This sample teaches how to reuse a test fixture in multiple test
+// cases by deriving sub-fixtures from it.
+//
+// When you define a test fixture, you specify the name of the test
+// case that will use this fixture. Therefore, a test fixture can
+// be used by only one test case.
+//
+// Sometimes, more than one test cases may want to use the same or
+// slightly different test fixtures. For example, you may want to
+// make sure that all tests for a GUI library don't leak important
+// system resources like fonts and brushes. In Google Test, you do
+// this by putting the shared logic in a super (as in "super class")
+// test fixture, and then have each test case use a fixture derived
+// from this super fixture.

+"""fuse_gtest_files.py v0.2.0
+Fuses Google Test source code into a .h file and a .cc file.
+
+SYNOPSIS
+ fuse_gtest_files.py [GTEST_ROOT_DIR] OUTPUT_DIR
+
+ Scans GTEST_ROOT_DIR for Google Test source code, and generates
+ two files: OUTPUT_DIR/gtest/gtest.h and OUTPUT_DIR/gtest/gtest-all.cc.
+ Then you can build your tests by adding OUTPUT_DIR to the include
+ search path and linking with OUTPUT_DIR/gtest/gtest-all.cc. These
+ two files contain everything you need to use Google Test. Hence
+ you can "install" Google Test by copying them to wherever you want.
+
+ GTEST_ROOT_DIR can be omitted and defaults to the parent
+ directory of the directory holding this script.
+
+EXAMPLES
+ ./fuse_gtest_files.py fused_gtest
+ ./fuse_gtest_files.py path/to/unpacked/gtest fused_gtest
+
+This tool is experimental. In particular, it assumes that there is no
+conditional inclusion of Google Test headers. Please report any
+problems to googletestframework@googlegroups.com. You can read
+https://github.com/google/googletest/blob/master/googletest/docs/AdvancedGuide.md for
+more information.

+
+The `gtest-config' script provides access to the necessary compile and linking
+flags to connect with Google C++ Testing Framework, both in a build prior to
+installation, and on the system proper after installation. The installation
+overrides may be issued in combination with any other queries, but will only
+affect installation queries if called on a built but not installed gtest. The
+installation queries may not be issued with any other types of queries, and
+only one installation query may be made at a time. The version queries and
+compiler flag queries may be combined as desired but not mixed. Different
+version queries are always combined with logical "and" semantics, and only the
+last of any particular query is used while all previous ones ignored. All
+versions must be specified as a sequence of numbers separated by periods.
+Compiler flag queries output the union of the sets of flags when combined.
+
+ Examples:
+ gtest-config --min-version=1.0 || echo "Insufficient Google Test version."
+
+ g++ $(gtest-config --cppflags --cxxflags) -o foo.o -c foo.cpp
+ g++ $(gtest-config --ldflags --libs) -o foo foo.o
+
+ # When using a built but not installed Google Test:
+ g++ $(../../my_gtest_build/scripts/gtest-config ...) ...
+
+ # When using an installed Google Test, but with installation overrides:
+ export GTEST_PREFIX="/opt"
+ g++ $(gtest-config --libdir="/opt/lib64" ...) ...
+
+ Help:
+ --usage brief usage information
+ --help display this help message
+
+ Installation Overrides:
+ --prefix=<dir> overrides the installation prefix
+ --exec-prefix=<dir> overrides the executable installation prefix
+ --libdir=<dir> overrides the library installation prefix
+ --includedir=<dir> overrides the header file installation prefix
+
+ Installation Queries:
+ --prefix installation prefix
+ --exec-prefix executable installation prefix
+ --libdir library installation directory
+ --includedir header file installation directory
+ --version the version of the Google Test installation
+
+ Version Queries:
+ --min-version=VERSION return 0 if the version is at least VERSION
+ --exact-version=VERSION return 0 if the version is exactly VERSION
+ --max-version=VERSION return 0 if the version is at most VERSION
+
+ Compilation Flag Queries:
+ --cppflags compile flags specific to the C-like preprocessors
+ --cxxflags compile flags appropriate for C++ programs
+ --ldflags linker flags
+ --libs libraries for linking

+"""Script for branching Google Test/Mock wiki pages for a new version.
+
+SYNOPSIS
+ release_docs.py NEW_RELEASE_VERSION
+
+ Google Test and Google Mock's external user documentation is in
+ interlinked wiki files. When we release a new version of
+ Google Test or Google Mock, we need to branch the wiki files
+ such that users of a specific version of Google Test/Mock can
+ look up documenation relevant for that version. This script
+ automates that process by:
+
+ - branching the current wiki pages (which document the
+ behavior of the SVN trunk head) to pages for the specified
+ version (e.g. branching FAQ.wiki to V2_6_FAQ.wiki when
+ NEW_RELEASE_VERSION is 2.6);
+ - updating the links in the branched files to point to the branched
+ version (e.g. a link in V2_6_FAQ.wiki that pointed to
+ Primer.wiki#Anchor will now point to V2_6_Primer.wiki#Anchor).
+
+ NOTE: NEW_RELEASE_VERSION must be a NEW version number for
+ which the wiki pages don't yet exist; otherwise you'll get SVN
+ errors like "svn: Path 'V1_7_PumpManual.wiki' is not a
+ directory" when running the script.
+
+EXAMPLE
+ $ cd PATH/TO/GTEST_SVN_WORKSPACE/trunk
+ $ scripts/release_docs.py 2.6 # create wiki pages for v2.6
+ $ svn status # verify the file list
+ $ svn diff # verify the file contents
+ $ svn commit -m "release wiki pages for v2.6"

+// 0 and it is destroyed, preventing the child from acquiring it. The
+// parent now has to release it, or read operations on the read end of
+// the pipe will not return when the child terminates.

+// learn how Google Test works by reading its unit tests, read
+// gtest_unittest.cc instead.
+//
+// This is intended as a regression test for the Google Test predicate

+// involved to set up the stage for testing Google Test using Google
+// Test itself.
+//
+// Currently, gtest_unittest takes ~11 seconds to run in the testing
+// daemon. In the future, if it grows too large and needs much more
+// time to finish, we should consider separating this file into a

+"""A script to prepare version information for use the gtest Info.plist file.

+ #defines in this header file will be included in during the generation of
+ the Info.plist of the framework, giving the correct value to the version
+ shown in the Finder.
+
+ This script makes the following assumptions (these are faults of the script,
+ not problems with the Autoconf):
+ 1. The AC_INIT macro will be contained within the first 1024 characters
+ of configure.ac
+ 2. The version string will be 3 integers separated by periods and will be
+ surrounded by square brackets, "[" and "]" (e.g. [1.0.1]). The first
+ segment represents the major version, the second represents the minor
+ version and the third represents the fix version.
+ 3. No ")" character exists between the opening "(" and closing ")" of
+ AC_INIT, including in comments and character strings.

+ <description>
+ This module provides an Apache Marmotta backend using blueprints abstraction on Accumulograph. This is a suitable backend in
+ high performance or big data scenarios. It does not support rule-based reasoning and versioning. NOTE:
+ This backend uses the Apache licensed AccumuloGraph library together with other Apache licensed products.
+ See from https://github.com/JHUAPL/AccumuloGraph/blob/master/LICENSE.

+<h1>Storage Backend: Accumulo</h1>
+
+<p>
+ This module provides an Apache Marmotta storage backend based on the <a href="https://github.com/JHUAPL/AccumuloGraph">the implementation of Tinkerpop Blueprints Accumulo backend.</a>
+ Accumulo supports various instance types (Distributed, Mini, Mock), which you need to
+ configure manually. This default installation uses Mock Accumulo backend for demonstration purposes.

+<h1>Storage Backend: LevelDB</h1>
+
+<p>
+ This module provides an Apache Marmotta storage backend based on a C++ LevelDB triple store (Ostrich). Ostrich is a highly scalable,
+ highly performant, highly concurrent triple store implementation that you can use in cases where your volume of data is very high and/or
+ you do not want/need to store your data in a relational database as with the KiWi backend.
