Cordova Paramedic (Test Automation)

Android Testsuite iOS Testsuite Chrome Testsuite

Paramedic • noun provides advanced levels of care at the point of illness or injury, including out of hospital treatment, and diagnostic services

cordova-paramedic is a tool to automate execution of Cordova plugins tests (via cordova-plugin-test-framework).

You can use Paramedic to build and run a Cordova app with plugin tests, run these tests on local emulators, and report the results. It can be used on a local or Continuous Integration environment.

Cordova Paramedic is currently used to automatically run all plugin tests on CI.

(See this workshop instructions for some additional explanation.)

Table of Contents

Supported Cordova Platforms

  • Android
  • Browser
  • iOS

What does it do?

A full Paramedic run will:

    1. Create a temporary Cordova project with cordova create
    2. Install various plugins with cordova plugin add %local_path% (e.g. cordova plugin add ../cordova-plugin-inappbrowser):
      • the plugin to be tested (e.g. ../cordova-plugin-inappbrowser)
      • the tests of this plugin (e.g. ../cordova-plugin-inappbrowser/tests)
      • cordova-plugin-test-framework (from npm)
      • local paramedic-plugin
    3. Update the app start page to the test page at cdvtests/index.html (provided by cordova-plugin-test-framework and the plugin tests)
    4. Add the platform to be tested with cordova platform add ...
    5. Confirm the requirements for that platform are met with cordova requirements ...
    6. Start a local socket server for communication between the app running on a device/emulator and paramedic
    7. Make the server address known to the app
  1. Run the tests
      1. Skip main tests if option set (platform != android)
      2. Start a file transfer server if required
      3. Get the test command for the platform
      4. Manipulate permissions on iOS
      5. Run the app (open in browser, start emulator, run on device or emulator) and start the tests by doing so
      6. Skip main tests if option set
      7. Skip tests if action = run|emulate (= build)
      8. Wait for device to connect to server before timeout
      9. Wait for the tests results
        1. Time out if “connection takes to long” TODO (failure)
        2. Receive and handle “tests are done” (success) and “device disconnected” (failure) events
      10. (browser) Close the running browser

Installation

Using npmjs registry version:

npm install -g cordova-paramedic

Using GitHub version:

npm install -g github:apache/cordova-paramedic

or

git clone https://github.com/apache/cordova-paramedic

If cloning from GitHub, you will need to run npm link inside the checkout repository.

Alternativly, replace all occurences of cordova-paramedic with the command:

  • cordova-paramedic/main.js for Linux or macOS
  • node cordova-paramedic/main.js for Windows

Usage

Paramedic parameters can be passed via command line arguments or separate configuration file:

By Command Line Arguments:

cordova-paramedic --platform PLATFORM --plugin PATH <other parameters>

By Configuration File:

cordova-paramedic --config ./sample-config/.paramedic.config.js

Common usages

Some common use cases of Paramedic:

Run without any parameters to get a list of supported parameters:

cordova-paramedic

Test your current plugin on an Android emulator:

cordova-paramedic --platform android --plugin ./

Test your current plugin on a specific Android device (ID via adb devices -l):

cordova-paramedic --platform android --plugin ./ --target 02e7f7e9215da7f8

Command Line Interface

What to build and test

--platform (required)

Specifies target Cordova platform (could refer to local directory, npm or git)

cordova-paramedic --platform ios --plugin cordova-plugin-inappbrowser
cordova-paramedic --platform ios@4.0 --plugin cordova-plugin-inappbrowser
cordova-paramedic --platform ios@../cordova-ios --plugin cordova-plugin-inappbrowser
cordova-paramedic --platform ios@https://github.com/apache/cordova-ios.git#4.1.0 --plugin cordova-plugin-inappbrowser

--plugin (required)

Specifies test plugin, you may specify multiple --plugin flags and they will all be installed and tested together. You can refer to absolute path, npm registry or git repo. If the plugin requires variables to install, you can specify them along with its name.

cordova-paramedic --platform ios --plugin cordova-plugin-inappbrowser
cordova-paramedic --platform ios --plugin 'azure-mobile-engagement-cordova --variable AZME_IOS_CONNECTION_STRING=Endpoint=0;AppId=0;SdkKey=0'
cordova-paramedic --platform ios --plugin https://github.com/apache/cordova-plugin-inappbrowser
// several plugins
cordova-paramedic --platform ios --plugin cordova-plugin-inappbrowser --plugin cordova-plugin-contacts

--verbose (optional)

Verbose mode. Display more information output

cordova-paramedic --platform ios --plugin cordova-plugin-inappbrowser --verbose

--cli (optional)

A path to Cordova CLI. Useful when you're testing against locally installed Cordova version.

cordova-paramedic --platform android --plugin cordova-plugin-device --cli ./cordova-cli/bin/cordova

--justbuild (optional)

Just builds the project, without running the tests.

cordova-paramedic --platform ios --plugin cordova-plugin-inappbrowser --justbuild

Emulator/Device to use for tests

--target (optional)

For Android: The device ID (from adb devices -l) of a device the tests should be run on.

cordova-paramedic --platform android --plugin cordova-plugin-contacts --target 02e7f7e9215da7f8

For iOS: A string that is used to pick the device (from the cordova run --list --emulator output) the tests should be run on.

cordova-paramedic --platform ios --plugin cordova-plugin-contacts --target "iPhone-8"

Test configuration

--timeout (optional)

Time in millisecs to wait for tests to pass|fail (defaults to 10 minutes).

cordova-paramedic --platform ios --plugin cordova-plugin-inappbrowser --timeout 30000

--outputDir (optional)

Directory location to store test results in junit format and the device logs

cordova-paramedic --platform ios --plugin cordova-plugin-inappbrowser --outputDir /Users/sampleuser/testresults

--cleanUpAfterRun (optional)

Flag to indicate the sample application folder must be deleted.

cordova-paramedic --platform ios --plugin cordova-plugin-inappbrowser --cleanUpAfterRun

--tccDb (optional)

iOS only parameter. The path to the sample TCC DB file, with permissions, to be copied to the simulator.

cordova-paramedic --platform ios --plugin cordova-plugin-contacts --tccDbPath tcc.db

--args (optional)

Add additional parameters to the cordova build and cordova run commands.

cordova-paramedic --platform ios --plugin cordova-plugin-contacts --args=--buildFlag='-UseModernBuildSystem=0'

Configuration file

Configuration file is used when no parameters are passed to cordova-paramedic call or explicitly specified via --config parameter:

cordova-paramedic           <- paramedic will attempt to find .paramedic.config.js in working directory
cordova-paramedic --config ./sample-config/.paramedic.config.js

Example configuration file is showed below.

module.exports = {
    verbose: false,
    plugins: ['https://github.com/apache/cordova-plugin-inappbrowser'],
    platform: 'android',
    action: 'run',
    args: ''
};

More configuration file examples could be found in sample-config folder.

API Interface

You can also use cordova-paramedic as a module directly:

const paramedic = require('cordova-paramedic');
paramedic.run(config);
