是否可以使用android espresso框架在多个活动中编写测试？

我已经看到了一些问题。

例如。Android Espresso测试应用程序流程

但是上面的答案在espresso 2中不起作用。这是我的摘录

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


@Test
public void splashActivityTest() {
    onView(withId(R.id.splash_container)).perform(swipeLeft());
    onView(withId(R.id.splash_container)).perform(swipeLeft());

    // launch the main activity
    ViewInteraction appCompatButton = onView(
            allOf(withId(R.id.introduction_goto_btn), withText("goToMainActivity"), isDisplayed()));
    appCompatButton.perform(click());

    // the hierarchy can't find HomeBtn , it still hold the Splash's View, so the code below will fail
    onView(withId(R.id.home_btn)).check(ViewAssertions.matches(isDisplayed()));
}

如果在一个TestFile中不允许进行多活动测试，那么如何进行测试多个活动的流程？

我正在进行一项测试,让我参加另一项活动.当我到达那里时,我需要等待对话消失.

  public class StressTest extends ActivityInstrumentationTestCase2<DashboardActivity> {

DashboardActivity activity;
ConsoleActivity consoleActivity;


public StressTest() {
    super(DashboardActivity.class);
}

public void setUp() throws Exception {
    super.setUp();
    activity = getActivity();
}

public void testRun() throws InterruptedException {
    schedule();
    quickstart();
    IP.enterIP();
<-----------FAILS HERE FROM A NPE------------------->
    while (consoleActivity.getConnectDialog() != null && consoleActivity.getConnectDialog().isShown()){
        Thread.sleep(
    } 
}

如你所见,我正在开始DashboardActivity.然后进入ConsoleActivity,我需要检查ConnectDialog.如果没有获得NPE,我怎么能这样做？

编辑

 public void testRun() throws InterruptedException {
    schedule();
    quickstart();
    IP.enterIP();
    Thread.sleep(500);

    getInstrumentation().runOnMainSync(new Runnable() {
        @Override
        public void run() {
            Collection<Activity> resumedActivities = ActivityLifecycleMonitorRegistry.getInstance().getActivitiesInStage(Stage.RESUMED); …
