Итак, у меня есть ViewModel с методом для получения данных с использованием контекста. Но при тестировании данные являются нулевыми, потому что при тестировании, возможно, нет контекста.
Код выглядит следующим образом:
Это тестирование кода ViewModel
public class FilmViewTest {
private FilmView filmView;
@Before
public void setUp() {
Application context = Mockito.mock(Application.class);
filmView = new FilmView(context);
FilmData filmData = new FilmData(context);
}
// ubah poster menjadi link
@Test
public void getFilms() {
List<ResultsItem> films = filmView.getFilms();
assertNotNull(films);
assertEquals(10, films.size());
}
}
и здесьэто сама ViewModel
public class FilmView extends AndroidViewModel {
public FilmView(@NonNull Application application) {
super(application);
}
private Context context = getApplication().getApplicationContext();
private FilmData filmData = new FilmData(context);
public List<ResultsItem> getFilms() {
return FilmData.generateFilms();
}
}
