Espresso AmbiguousViewMatcherException podczas próby kliknięcia przycisku nawigacyjnego

Question

Test, który próbuję wykonać: dokonać zakupu, zanotuj tytuł, a następnie wróć do działania w domu i naciśnij "home_image", który jest przyciskiem obrazu.

Mój problem polega na tym, że nie mogę poruszać się po home_image. Naciskam to i otrzymuję fałszywy duplikat ID. Wierzę, że duplikat identyfikatora odnosi się do niewidocznych fragmentów, które mają ten sam identyfikator. Dlaczego nie jest to problem na początku testu jest dziwne. Przepraszamy, musiał skrócić dzienniki, ze względu na limit tekstu. To, co chciałbym zrobić, to po prostu uruchomić aktywność domową bezpośrednio, ale ten apartament jest o połowę uciążliwy dla prostych rzeczy. Nawet polecenie przesunięcia otrzyma ten błąd! Po raz pierwszy wszystkie te przyciski działają, myślę, że to błąd w espresso i potrzebuję obejść.

Dzięki za pomysły!

Answer 1

To nie jest błąd w espresso. Hierarchia widoku wyraźnie pokazuje dwa widoki o tym samym ID. Jest to prawdopodobnie spowodowane tym, że widok znajduje się wewnątrz ViewPagera, którym jest AdapterView. Tak więc należy oczekiwać wielu wystąpień.

Aby rozwiązać ten problem, lepiej dopasuj widok do widoku. Idąc po ID nie pomaga. Ponieważ drugi przycisk ImageView dla przycisku głównego nie jest widoczny, ponieważ jego rodzic jest GONE, możesz po prostu dopasować do niego:

onView(allOf(withId(..), withEffectiveVisibility(VISIBLE))).perform(click());
