我刚开始在Android Studio上进行测试，因此我的项目即将完成。我想测试添加到Firebase等中的用户，但首先我需要先让我的简单测试开始工作...我的简单测试主要是我试图检查页面是否已打开或是否是用户已登录。我下面的代码是我尝试过但无法使用的代码。我也发布了堆栈跟踪。
@RunWith(AndroidJUnit4.class)
public class ExampleInstrumentedTest {
@Test
public void useAppContext() {
// Context of the app under test.
Context appContext = InstrumentationRegistry.getTargetContext();
assertEquals("com.example.seansandroid.dementiaapp", appContext.getPackageName());
}
@Rule
public ActivityTestRule <SignInActivity> SignInActivityTestRule =
new ActivityTestRule<SignInActivity>(SignInActivity.class);
@Test
public void testLaunchOfSignInActivityOnButtonClick() {
Instrumentation.ActivityMonitor monitor = getInstrumentation().addMonitor(
SignUpActivity.class.getCanonicalName(), null, true);
//check that the signin button exists
assertNotNull(onView(withId(R.id.button_sign_in)));
//click the signin button
onView(withId(R.id.button_sign_in)).perform(click());
//
Activity signInActivity = getInstrumentation().waitForMonitorWithTimeout(monitor, 30000);
//check that signin activity exists
assertNotNull(signInActivity);
//test completed
signInActivity.finish();
}
@Test
public void testIfAPageIsLaunched(){
Instrumentation.ActivityMonitor monitor = getInstrumentation().addMonitor(
SignUpActivity.class.getCanonicalName(), null, true);
//Do something, for example press a focused button
assertNotNull(onView(withId(R.id.text_view_register)));
onView(withId(R.id.text_view_register)).perform(click());
assertTrue(getInstrumentation().checkMonitorHit(monitor, 1));
}
@Test
public void testIfUserIsLoggedInOrNot() {
Instrumentation.ActivityMonitor monitor = getInstrumentation().addMonitor(
SignInActivity.class.getCanonicalName(), null, true);
assertNotNull(onView(withId(R.id.button_sign_in)));
onView(withId(R.id.button_sign_in)).perform(click());
Activity signInActivity = getInstrumentation().waitForMonitorWithTimeout(monitor, 50000);
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
assertNotNull(signInActivity);
if(user != null){
System.out.println("User is Signed In");
} else {
System.out.println("There is no one Signed In");
}
signInActivity.finish();
}
}

我知道它问我是否启动了一项活动，但是我的click（）方法不是这样做的吗？谢谢您的帮助。
