How to test an IntentService with Robolectric?

Issue

I'm trying to test the onHandleIntent() method of an IntentService using Robolectric.

I'm starting the service with:

Activity activity = new Activity();
Intent intent = new Intent(activity, MyService.class);
activity.startService(intent);

ShadowActivity shadowActivity = Robolectric.shadowOf(activity);
Intent startedIntent = shadowActivity.getNextStartedService();
assertNotNull(startedIntent);

seems like startedIntent is not null, but onHandleIntent() doesn't seem to be called.

how should I test it ?

Solution

onHandleIntent is a protected method so it can't be called directly.

my solution was to extend the service class in my test case, override onHandleIntent making it public and calling super.onHandleIntent(intent)

then call onHandleIntent directly from the test case.
