Espresso how to test if Activity is finished?

Question

I want to assert that my Acitivty that I am currently testing is finished when certain actions are performed. Unfortunately so far I am only to assert it by adding some sleep at the end of the test. Is there a better way ?

import android.content.Context; import android.os.Build; import android.support.test.rule.ActivityTestRule; import android.test.suitebuilder.annotation.LargeTest;  import org.junit.Before; import org.junit.Rule; import org.junit.Test; import org.junit.runner.RunWith; import org.junit.runners.JUnit4;  import static org.junit.Assert.assertTrue;  @SuppressWarnings("unchecked") @RunWith(JUnit4.class) @LargeTest public class MyActivityTest {      Context context;      @Rule     public ActivityTestRule<MyActivity> activityRule             = new ActivityTestRule(MyActivity.class, true, false);      @Before     public void setup() {         super.setup();         // ...     }      @Test     public void finishAfterSomethingIsPerformed() throws Exception {          activityRule.launchActivity(MyActivity.createIntent(context));          doSomeTesting();          activityRule.getActivity().runOnUiThread(new Runnable() {             @Override             public void run() {                 fireEventThatResultsInTheActivityToFinishItself();             }         });          Thread.sleep(2000); // this is needed :(          if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {             assertTrue(activityRule.getActivity().isDestroyed());         }      }  }

In my case I can test for isFinishing():

assertTrue(activityTestRule.getActivity().isFinishing());

instead of:

    Thread.sleep(2000); // this is needed :(      if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {         assertTrue(activityRule.getActivity().isDestroyed());     } 

Another advantage of isFinishing() is, that you do not need the Version check.
