Add support for Spoon in Android test modules

[patrickhammond]

I am trying to include Spoon in an Android test module (https://developer.android.com/tools/studio/studio-features.html#test-module), but it looks like that plugin type is not supported yet (https://github.com/stanfy/spoon-gradle-plugin/blob/master/src/main/groovy/com/stanfy/spoon/gradle/SpoonPlugin.groovy#L23).

Correct. This plugin use case is putting tests into the app module under `src/androidTest/. What you can do is configuring spoon task on your own in your test module: add the plugin artifact to the build script classpath (but do not apply it) and then do something like

import com.stanfy.spoon.gradle.SpoonRunTask
android.applicationVariants.all { variant ->
  task "spoon${variant.name.capitalize()}"(type: SpoonRunTask) {
    testSize = SpoonRunTask.TEST_SIZE_ALL
    applicationApk = variant.outputs[0].outputFile
    instrumentationApk = variant.outputs[0].outputFile
    // ... See other options https://github.com/stanfy/spoon-gradle-plugin/blob/master/src/main/groovy/com/stanfy/spoon/gradle/SpoonRunTask.groovy#L33-L90
  }
}

Or you can add another plugin to this project that can be applied to test modules.

Hi Roman. I'm in a similar position as patrick. I have an Android library project that has about 5 different modules in it, each with their own set of unit tests. I would love to use spoon as it let's me use multiple devices and is great for granting runtime permissions for the tests.

This would be a great feature to have! But for now, I'm looking at the sample code you provided above. I'm pretty new with gradle, so I was hoping you could expand upon your sample code and maybe explain how I could get something working. For example: Not sure what you mean by "adding plugin artifact to the buildscript classpath (but do not apply it)." Also would I add that task to each of my module level build.gradle files? Or top level? My project doesn't use flavors or variants.

Sorry I'm a gradle noob, but I would love to get Spoon working so any help is appreciated!
