使用测试记录器创建测试时，Android Espresso提供NoMatchingViewException

Question

我是Espresso测试框架的新手，要开始使用，我在Github上拉了一个名为SeriesGuide的随机项目。

我正在使用Android Studio，在那里我使用内置的Test Recorder进行简单的UI测试。但是问题是我得到了以下错误

androidx.test.espresso.NoMatchingViewException: No views in hierarchy found matching:

我要创建的测试是将影片添加到用户的监视列表，然后导航到所述监视列表。这是我目前拥有的

@LargeTest
@RunWith(AndroidJUnit4.class)
public class ShowsActivityTest3 {

@Rule
public ActivityTestRule<ShowsActivity> mActivityTestRule = new ActivityTestRule<>(
        ShowsActivity.class);

@Test
public void showsActivityTest3() {

如果有人能指出正确的方向来进行测试，将不胜感激。
