My Android unit test is failing with initializationError if RunWith RobolectricTestRunner.
import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.JUnit4;
import org.robolectric.RobolectricTestRunner;
import static junit.framework.Assert.assertEquals;
@RunWith(RobolectricTestRunner.class) // If I use @RunWith(Junit4.class) it works
@Config(application = Application.class)
public class LoginActivityTest {
@Test
public void sampleTest() {
assertEquals("actualMessage", "expectedErrorMessage");
}
}
Here is the entire stacktrace:
