Robolectric: IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity
I'm new to Robolectric and instrumentation testing in general on Android. I followed along the guide for Robolectric for testing my first test. However I'm getting:
java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.
I searched for the error, but no solution is helping. I'm including everything that could cause this error.

Answer
I've just fixed same issue, and my workaround was this:
create a dummy Application and set theme inside onCreate():
public class TestApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
setTheme(R.style.AppTheme); //or just R.style.Theme_AppCompat
}
}
then inside the test you specify the application class in config:
@RunWith(RobolectricTestRunner.class)
@Config(application = TestApplication.class)
public class YourActivityTest {
//tests
}
