How I know if one fragment is displayed (Test UI)

Question

If one of my fragments, rattingfragment, I have to perform click. If not, do other action.

How I know this is the fragment on my screen?

Android UI Tests. Below my code to test EDIT CODE:

   @Rule
    public ActivityTestRule mActivityRule = new ActivityTestRule<>(MainActivity.class);

    @After
    public void setUp(){
        Logout();
    }  
  @Test
    public void shouldOfferRide(){
        SystemClock.sleep(1500);
        Login();
        onView(withId(R.id.searchButton)).perform(typeText(emailSearch));
        onView(withId(R.id.searchButton)).perform(pressImeActionButton());
        onView(withId(R.id.community_user_ask_button)).perform(click());
        SystemClock.sleep(1500);
        onView(withId(R.id.button1)).perform(click());
        onView(withId(R.id.send_request)).perform(click());
        SystemClock.sleep(1500);
        ((MainActivity)mActivityRule.getActivity()).navItemClick(4);
        SystemClock.sleep(3500);
        LoginMyrides();
        onView(withId(R.id.my_rides_tab_bar)).perform(click());
        SystemClock.sleep(1000);

        {I have to know is ratingfragment before perform click below}

        onView(withId(R.id.rating_bar)).perform(click());
        onView(withId(R.id.deny_btn)).perform(click());
    }

        public void Login(){
        onView(withId(R.id.edt_new_login_email)).perform(typeText(emailLogin));
        onView(withText(R.string.next_button)).perform(click());
        onView(withId(R.id.edt_new_password)).perform(typeText(senha));
        onView(withText(R.string.login_new_pass)).perform(click());
    }

    public void Logout(){
        new SessionManager(mActivityRule.getActivity()).logoutUser();
    }
}

Espresso was designed for tests which can follow a step by step recipe without any decision making. You should consider situations when the fragment will be visible and when it will not be. Then write separate tests for each scenario.
