How to validate whether opened correct activity - Espresso

问题

I created android UI test with espresso and done Button click and opening an Activity. Now I want to validate whether opened correct activity or not.

回答1:

Use espresso-intents to validate that.

The usage is:

intended(hasComponent(NewActivity.class.getName()));

You can read this thread for more details on that: Espresso - check which Activity is opened using intent on button press?

回答2:

You want get the instance of activity rule which you have register and compare it with the activity which you want.

// Define activity rule
    @Rule
        public ActivityTestRule<MainActivity> mActivityRule = new ActivityTestRule<>
                MainActivity.class);


    // compare activity rule activity with the activity you want to check.

    Assert.assertEquals(mActivityRule.getActivity(), MainActivity.class);
