# Testing Apache Celix

This document describes how to build and run tests for Apache Celix.

## Building Tests

Celix uses CMake and Google Test for its unit and integration tests. To build the tests, ensure you have all dependencies installed, then run:

```sh
cmake -B build -DENABLE_TESTING=ON -DCMAKE_BUILD_TYPE=Debug
cmake --build build
```

```sh
#conan

To enable AddressSanitizer (ASAN) when building tests, configure CMake with the `ENABLE_ASAN` option:

```sh
cmake -B build -DENABLE_TESTING=ON -DENABLE_ADDRESS_SANITIZER=ON -DCMAKE_BUILD_TYPE=Debug
cmake --build build
```

This will build Apache Celix and its tests with ASAN enabled, helping to detect memory errors during test execution.

## Running Tests

After building, you can run all tests using CTest:

```sh
ctest --output-on-failure --test-dir build
```

Or run a test for a specific subdir, e.g.: 

```sh
ctest --output-on-failure --test-dir build/bundles/shell
```

Or run a specific test binary directly from the `build` directory, e.g.:

```sh
./build/bundles/components_ready_check/tests/components_ready_check_test
```
