composer-gradle-plugin

Gradle task type and plugin for running gojuno/composer from gradle.

Installation & Usage

In the appropriate build.gradle file add the jitpack repository and classpath dependency.

buildscript {
    repositories {
        maven { url "https://jitpack.io" }
    }
    dependencies {
        classpath 'com.github.trevjonez.composer-gradle-plugin:plugin:0.6.0'
    }
}

This can be consumed in two ways, via a android variant aware plugin or as a pre-provided task type.

Plugin

apply plugin: 'composer'

The above should be all you need to get started and will create a task for each testable variant in the project.

The tasks that are created will be of the form testFlavorTypeComposer

If you want to limit the variants that get tasks or provide custom configuration you can do so via the composer DSL block:

composer {
  variants "redDebug" // optional, variant names to create composer tasks for. If empty all testable variants will receive a task.
  instrumentationArgument('key1', 'value1') //optional. args that apply to all created tasks
  instrumentationArgument('key2', 'value2')
  instrumentationArgument('keyN', 'valueN')

  configs { 
    redDebug {
      apk 'app/build/outputs/apk/example-debug.apk' //optional override
      testApk 'build/outputs/apk/example-debug-androidTest.apk' //optional override
      shard true //optional. default true
      outputDirectory 'artifacts/composer-output' //optional override. default 'build/reports/composer/redDebug'
      instrumentationArgument('key1', 'value1') //optional
      instrumentationArgument('key2', 'value2')
      instrumentationArgument('keyN', 'valueN')
      verboseOutput false //optional default false
      device 'emulator-5554' //optional, additive
      device 'emulator-5558'
      devices('emulator-5554', 'emulator-5558') //optional, additive
      devicePattern 'somePattern' //optional
      apkInstallTimeout 90 //optional, timeout in seconds default 120
    }
  }
}

Core

Manual task creation looks something like this:

task customTaskName(type: ComposerTask) {
  apk 'app/build/outputs/apk/example-debug.apk' //required
  testApk 'build/outputs/apk/example-debug-androidTest.apk' //required
  shard true //optional
  outputDirectory 'artifacts/composer-output' //optional
  instrumentationArgument('key1', 'value1') //optional
  instrumentationArgument('key2', 'value2')
  instrumentationArgument('keyN', 'valueN')
  verboseOutput false //optional
  device 'emulator-5554' //optional
  device 'emulator-5558'
  devices('emulator-5554', 'emulator-5558') //optional
  devicePattern 'somePattern' //optional
  apkInstallTimeout 90 //optional
}

Dependency Configuration

If you need to use a different version of the composer jar than this plugin uses by default, you can modify the composer configuration with normal gradle strategies. The composer configuration is added to your project once a ComposerTask has been created or the plugin has been applied to the project.

dependencies {
 composer "com.gojuno.composer:composer:0.3.2"
}

Disclaimer

So far this plugin has had light use in the wild and the test cases only verify that composer is ran. Please give any feedback possible if you have issues so I can make things work as expected.

Notes on Compatibility

The plugin is developed against specific version of gradle and the android gradle plugin. In most cases using the latest version of gradle is safe but the minimum supported version of gradle is 4.0 or whatever minimum is mandated by the android gradle plugin.

Composer plugin version	Gradle version	Android plugin version
0.6.0	4.6	3.1.0
