How do I write Firebase Android Instrumentation Tests?

I am trying to use Firebase as the backend for my app. If I use the following quickstart guide within my app everything works.

If I check on my firebase data page, data is successfully written.

However if I try to do the same thing inside of an androidTest (instrumentation test) nothing happens - no data is written to the firebase database. I have specified Internet permission in my androidTest manifest, so wondering if there is something else that I need to do to be able to write to firebase from within my tests?

On a related note, once I can do this within instrumentaiton tests, is there a way I can do the same in unit tests?

Many thanks,

Riz

Edit: here is the test I'm trying to run:

public class FirebaseTest extends InstrumentationTestCase{
    private static final String FIREBASE = "https://my-app-name.firebaseio.com/";

    @Override
    @Before
    public void setUp() {
        injectInstrumentation(InstrumentationRegistry.getInstrumentation());
        Firebase.setAndroidContext(getInstrumentation().getTargetContext());
    }

   @Test
   public void testWrite(){
       Firebase cloud = new Firebase(FIREBASE);
       cloud.child("message").setValue("Do you have data? You'll love Firebase.");
   }
}

In your main application you can define an androidApplication class to initialize your Firebase Context. Then create an ApplicationTest that extends the ApplicationTestCase :

In Main source :

public class MyApplication extends android.app.Application {

    @Override
    public void onCreate() {
       super.onCreate();
       Firebase.setAndroidContext(this); //initializeFireBase(context);
       isInitialized = true;
    }
}

In your Android Test :

public class ApplicationTest extends ApplicationTestCase<MyApplication> {

    private static MyApplication application;

    public ApplicationTest() {
        super(MyApplication.class);
    }

   @Override
   public void setUp() throws Exception {
      super.setUp();
      if (application == null) {
          application = getApplication();
      }
      if (application == null) {
         application = (MyApplication) getContext().getApplicationContext();
         assertNotNull(application);
         long start = System.currentTimeMillis();
         while (!application.isInitialized()){
             Thread.sleep(300);  //wait until FireBase is totally initialized
             if ( (System.currentTimeMillis() - start ) >= 1000 )
                 throw new TimeoutException(this.getClass().getName() +"Setup timeOut");
         }
      }
   }


   @Test
   public void testWrite(){
       Firebase cloud = new Firebase(FIREBASE);
       cloud.child("message").setValue("Do you have data? You'll love Firebase.");
   }

}
