我在Android Studio中工作，正在尝试测试Button单击是否启动了新的Activity。在模拟器中，活动已明确启动，但是我不断收到异常。对于我测试的任何按钮，它将启动新的活动。我试图仅检查新活动中的现有视图，但效果不佳。

代码：

@RunWith(AndroidJUnit4.class)
public class MainActivityTest {

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

   @Before
    public void setUp() throws Exception {
        mainActivity = mainActivityActivityTestRule.getActivity();
    }

    @Test
    public void checklogin() throws Exception {
        onView(withId(R.id.loginbutton))
                .perform(click());

        Intents.init();
        intended(hasComponent(LoginActivity.class.getName()));
        Intents.release();
    }

    @After
    public void tearDown() throws Exception {
        mainActivity = null;
    }
}

Stacktrace：
