EDIT: Updated description and error message and added some images. Still have this problem.

I have a strange error that occur many times when running espresso tests. After a couple of successful test runs the tests starts failing with following exception:

06-23 13:04:48.443  info    TestRunner  finished: WhenNavigatingToReportsThenCorrectViewShouldBeShown(com.myapp.ui.views.MainActivityTest)

I have a simple app with navigation to pages just containing text at this point, and the test should navigate to each page and identify this text. 

@RunWith(AndroidJUnit4.class)
@LargeTest
public class MainActivityTest {

@Rule
public ActivityTestRule<MainActivity> mActivityRule = new ActivityTestRule(MainActivity.class);
private MainActivity mainActivity;

@Before
public void setActivity() {
    mainActivity = mActivityRule.getActivity();
}

 @Test
public void WhenNavigatingToReportsThenCorrectViewShouldBeShown() {
    onView(allOf(withId(R.id.icon), hasSibling(withText(R.string.reports)))).perform(click());

    onView(withText("This is the Reports Activity.")).check(matches(isDisplayed()));
    Spoon.screenshot(mainActivity, "main_view");
}
}

This failure only occurs on the real device. On emulated device the tests works fine. See images below.

All tests are executed by gradle script, starting with removing the previous app and test api, before installing it again. To ensure clean environment. The log indicates that uninstallation has been successful. Then deploying the new app and start running the tests. Now they fail.

If the tests have failed, it's not until I manually remove the app and the test api from device that I can get successful tests again. But only for a while until the same error occur.

Why do I get NoActivityResumedException, I can't find a good example of what it is and when it occurs.

I had the same problem. This happen when the screen on device is off. Turn screen on should fix the problem.
