Unit testing on Android Studio: “not mocked” error

Question

I am new to Android Studio. I am using Android Studio 1.2 preview 2, gradle 2.2.1 and gradle plugin 1.1.0.

I cannot get around this error, when trying to run my unit te

Answer 1

I couldn't get Instrumentation tests to work, using Android Studio, I guess they're still finalising the implementation. And since it needs to run on the emulator, there are faster options: regular unit tests.

Thanks to Jared's tips, I switched to Robolectric, which is easy to use on Android Studio.

androidTestCompile 'junit:junit:4.12'
androidTestCompile "org.robolectric:robolectric:3.0"

and

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.robolectric.RuntimeEnvironment;
import org.robolectric.RobolectricTestRunner;
import static junit.framework.TestCase.assertEquals;

@RunWith(RobolectricTestRunner.class)
public class AppPreferencesTest {

    AppPreferences preferences;

    @Before
    public void setUp() throws Exception {
        preferences = new AppPreferences(RuntimeEnvironment.application.getApplicationContext());
    }

    @Test
    public void testIsNotificationsEnabled_Default() throws Exception {
        assertEquals(true, preferences.isNotificationsEnabled());
    }

    ...

The info here seems to be correct at this time: http://nenick-android.blogspot.nl/2015/02/android-studio-110-beta-4-and.html But will probably deprecate again in the near future, as all the info I found on this subject using google deprecated already.
