gradle-android-test-plugin

To run unit tests for your android code:

• Create a new java module outside the android module that you want to test
• Apply the android-test plugin to the test module

buildscript {
    repositories {
        mavenCentral()
        maven {
            url "https://oss.sonatype.org/content/repositories/snapshots/"
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
        classpath 'com.novoda:gradle-android-test-plugin:0.9.3-SNAPSHOT'
    }
}
apply plugin: 'java'
apply plugin: 'android-test'

• Add your tests under scr/test/java
• Don't forget to add a dependency from your test module to the android module e.g.

dependencies {
    testCompile 'junit:junit:4.11'
    testCompile 'org.mockito:mockito-core:1.9.5'
    testCompile 'com.squareup:fest-android:1.0.+'
    testCompile 'org.robolectric:robolectric:2.1.+'
}

• Last but not least, tell the plugin which is the android module that you want to test

android {
    projectUnderTest ':novoda-app'
}

• Congratulation, you can now run unit tests against your android source!
• Known issues: the IDE does not support running a single test in isolation. You have to run the whole suite
• Known boons: plugins respect testCompile dependencies and runs JUnit tests, TenstNG, Robolectric and Spock
• Working towards: scala and jacoco full support
