我正在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。 我只是尝试检查新活动中的现有视图，但这并不能正常工作。
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;
}
}
