Robolectric JUnit and Espresso 2.0 tests running in an example app.
You should now be able to DeckardActivityRobolectricTest. Run it as a normal JUnit test - make sure to choose the JUnit test runner and not the Android one.
To run the Espresso test, you need to set up a Run Configuration. Go to Edit Configurations -> Defaults -> Android Tests and, after choosing the correct module (deckard-gradle), fill in the Specific instrumentation test runner field. The easiest way is to click the ellipsis button on the right and type in GITR. This will find GoogleInstrumentationTestRunner, which is what you want. The fully-qualified class name will appear. Now you can right click on the test method in DeckardEspressoTest and choose the Android test runner.
