Spoon Gradle Plugin

Gradle plugin for Spoon. Allows you to run spoon with almost no effort under new Android build system.

Plugin generates spoon${TEST_VARIANT} tasks for every test variation in your application project.

Usage

buildscript {
  repositories {
    mavenCentral()
  }

  dependencies {
    classpath 'com.stanfy.spoon:spoon-gradle-plugin:1.2.2'
  }
}

apply plugin: 'spoon'

// This section is optional
spoon {
  // for debug output
  debug = true

  // To run a single test class
  className = 'fully.qualified.TestCase'

  // To run a single method in TestCase
  methodName = 'testMyApp'

  // To execute the tests device by device */
  sequential = true

  // To grant permissions to Android M >= devices */
  grantAllPermissions = true
}

After applying the plugin you'll find spoon${TEST_VARIANT} tasks in your project.

You may run all the test variations with

gradle spoon

Generated reports are available at build/spoon/${TEST_VARIANT} folder.

For making screenshots add spoon-client dependency to your tests compile configuration:

dependencies {
  androidTestCompile 'com.squareup.spoon:spoon-client:1.6.4'
}

By default the plugin runs tests on all the connected devices. In order to run them on some concrete devices instead, you may specify their serial numbers:

spoon {
  devices = ['333236E9AE5800EC']
  skipDevices = ['serial-you-want-to-skip']
}

It is also allowed to specify specify size of tests that should be run. You may run all the tests annotated as @SmallTest with the following line:

gradle spoonSmall

Run gradle tasks for details about size rules.

You may also setup your project to take parameters for class/method to be run from command line. E.g.:

gradle spoon -PspoonClassName=fully.qualified.TestCase

And project configuration:

spoon {
  if (project.hasProperty('spoonClassName')) {
    className = project.spoonClassName  
  }
}

Test Sharding

You can configure test sharding using the numShards and shardIndex properties (documentation):

spoon {
  numShards = 4
  shardIndex = 0
}

If you are specifying sharding for multiple devices, you may use spoon's built in auto-sharding by specifying:

spoon {
  shard = true
}

This will automatically shard across all specified serials, and merge the results.

Custom instrumentation arguments

Use the instrumentationArgs property on spoon extension to pass custom parameters to your tests:

spoon {
  instrumentationArgs = ["foo=bar", "name=value"]
}

Code Coverage

You can configure spoon to calculate code coverage by using codeCoverage property on spoon extension:

spoon {
  codeCoverage = true
}

This option requires your app to have the WRITE_EXTERNAL_STORAGE permission.

Known issues

If you have troubles with running Android Lint after this plugin is applied, try the following workaround

buildscript {
  // ...
  dependencies {
    classpath('com.stanfy.spoon:spoon-gradle-plugin:1.2.2') {
      exclude module: 'guava'
    }
    classpath 'com.google.guava:guava:17.0'
  }
}

You can find details in the related issue.

Testing

After making editions, run

./gradlew integrationTest

This will install the plugin to local maven repo and run spoon task in the example project.
