Sample test with Espresso fails

I have added Espresso test to my application. When I write a simple test code for launcher Activity in my app everything works fine:

import static com.google.android.apps.common.testing.ui.espresso.Espresso.onView;
import static com.google.android.apps.common.testing.ui.espresso.assertion.ViewAssertions.matches;
import static com.google.android.apps.common.testing.ui.espresso.matcher.ViewMatchers.withId;
import static com.google.android.apps.common.testing.ui.espresso.matcher.ViewMatchers.withText;

@LargeTest
public class DeckardEspressoTest extends ActivityInstrumentationTestCase2<MainActivity> {

    public DeckardEspressoTest() {
        super(MainActivity.class);
    }

    @Override
    public void setUp() throws Exception {
        super.setUp();
        getActivity();
    }

    public void testActivityShouldHaveText() throws InterruptedException {
        onView(withId(R.id.text)).check(matches(withText("Hello Espresso!")));
    }
}

When I use the same sample code for another Activity which is not launcher Activity, it fails:

Test failed to run to completion. Reason: 'Instrumentation run failed due to 'java.lang.NullPointerException''. Check device logcat for details

And this is what I receive in logcat:

Do you have any idea about the problem?
