Robolectric and Google Analytics Error on Tests

Question

I've been running tests with Robolectric and it's all been great. Then I implemented Google Analytics to my application class and the tests started failing. The failing seems to occur when I inflate views during tests. Here's the stack trace:

java.lang.NullPointerException: null

Here's the Robolectric code for my BaseActivity:

@RunWith(RobolectricTestRunner.class)
public class BaseActivityTest {

ActivityController<TestActivity> activityController;
TestActivity activity;

@Before
public void setUp(){
    activityController = Robolectric.buildActivity(TestActivity.class).create().start();
}


@After
public void takeDown(){
    activityController.stop().destroy();
    activity = null;
}

@Test
public void testOnPauseState(){
    activity = activityController.resume().pause().get();
    assertFalse(activity.getBus().isActive());
}
}

Following the Google Analytics example, my Application class implements Google Analytics. Whenever I run the tests with my Application, the break occurs. I've tried implementing Robolectric's MockApplication object, but that had no change; I had to remove Google Analytics from my Application object to have it work. Does anyone have any solutions that would allow me to run Robolectric with Google Analytics?

Answer 1

There is another solution if the previous posts don't work. Get a handle to the shadow application and configure it to ignore the analytics start intent binding. Do this in your test setup.

@Before
public void setup() {
    ShadowApplication shadowApplication = Robolectric.shadowOf(Robolectric.application);
    shadowApplication.declareActionUnbindable("com.google.android.gms.analytics.service.START");
}

Answer 2

I have two suggestions for you if you are using Google Analytics V3:

1) Have you tried calling this method when you run your tests?

 googleAnalytics.setAppOptOut(true); 

This will disable google analytics for the lifetime of the test.

2) Create a test application class in the same package as your current application and name it the same name but prepend "Test" to the name. This application will be created during your tests and you can set "setAppOptOut" set to true or you can omit GoogleAnalytics altogether from it.
