> Android Tools Project Site – Unit testing support

Unit tests run on a local JVM on your development machine. Our gradle plugin will compile source code found in src/test/java and execute it using the usual Gradle testing mechanisms. At runtime,tests will be executed against a modified version of android.jar where all final modifiers have been stripped off. This lets you use popular mocking libraries,like Mockito.

> Android Plugin for Gradle Release Notes

Added sharing of the mockable android.jar,which the plugin generates only once and uses for unit testing. Multiple modules,such as app and lib,now share it. Delete $rootDir/build to regenerate it.
