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.

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
}
Try this: Change your Android Manifest file to this:
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/Theme.AppCompat" >
<activity
android:name=".ui.MainActivity"
android:label="@string/title">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

It is a bug with Robotelectric, here is a workaround:
Android Lolipop Appcompat problems running with Robolectric
You may also try to upgrade to Robotelectric 3.0 to check if this is fixed.
You should use RobolectricGradleTestRunner instead.
import org.robolectric.RobolectricGradleTestRunner;
@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class, manifest = Config.NONE)
public class MainActivityRoboTest {
It solves my problem.

Just use @RunWith(RobolectricTestRunner.class) and be happy
@RunWith(RobolectricTestRunner.class)
public class MainActivityTest {
@Test
public void myTest() throws Exception {
assertEquals(true, true);
}
}
