If you want to test whether expected intent is sent without actually launching the activity you can do it by capturing the intent with an activityResult and then catching the activity :

Intent intent = new Intent();
ActivityResult intentResult = new ActivityResult(Activity.RESULT_OK,intent);

intending(anyIntent()).respondWith(intentResult);

onView(withId(R.id.view_id_to_perform_clicking)).check(matches(isDisplayed())).perform(click());

intended(allOf(hasComponent(ActivityToBeOpened.class.getName())));

This would catch any attempt of launching ActivityToBeOpened. If you want to be more specific you can also catch an intent with Extras:

intended(allOf(hasComponent(ActivityToBeOpened.class.getName()), hasExtra("paramName", "value")));

Hope that helps.
