Этот вопрос возник из первой части PowerMock + Robolectric + Dagger2
Так что я снова немного. Сожалею.
я проверить пользовательский класс представления, которые содержат:PowerMock + Robolectric + Dagger2. Часть I
- андроида элементы пользовательского интерфейса
- некоторой логику
- статических методов призваний
- зависимости dagger2
Так я использую следующие инструменты для испытания
- Robolectric для элементов пользовательского интерфейса насмешливых
- модульных тестов для логического тестирования
- PowerMock для статических методов насмешливых
Robolectric + PowerMock проблема интеграции известна и решение, как известно, - https://github.com/robolectric/robolectric/wiki/Using-PowerMock
Но с этим решением проблемы с кинжалом2 терпят неудачу.
Внимание к коду
Мой заказ вид - ProgressTextView:
public class ProgressTextView extends TextView {
private String defaultText;
private int fileSize;
private String fileSizeString;
private FileDownloaderI fileDownloader;
@Inject
FileDownloaderManager fileDownloaderManager;
Subscription downloadProgressChannelSubscription;
Subscription downloadCancelChannelSubscription;
public ProgressTextView(Context context) {
super(context);
provideDependency();
}
public ProgressTextView(Context context, AttributeSet attrs) {
super(context, attrs);
provideDependency();
}
public ProgressTextView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
provideDependency();
}
private void provideDependency() {
ApplicationSIP.get().applicationComponent().inject(this);
}
}
ApplicationSIP:
public class ApplicationSIP extends Application {
public static volatile Context applicationContext;
@NonNull
private AppComponent appComponent;
@Override
public void onCreate() {
super.onCreate();
applicationContext = getApplicationContext();
Logger.registerLogger(this);
appComponent = prepareApplicationComponent().build();
appComponent.inject(this);
}
@NonNull
protected DaggerAppComponent.Builder prepareApplicationComponent() {
return DaggerAppComponent.builder()
.appModule(new AppModule(getApplicationContext()))
.tGModule(new TGModule());
}
@NonNull
public AppComponent applicationComponent() {
return appComponent;
}
@NonNull
public static ApplicationSIP get() {
return (ApplicationSIP) applicationContext.getApplicationContext();
}
}
AppComponent:
@Component(modules = {AppModule.class, TGModule.class, MediaModule.class, StaticModule.class})
@Singleton
public interface AppComponent {
void inject(ApplicationSIP applicationSIP);
void inject(ProgressDownloadView progressDownloadView);
void inject(ProgressTextView progressTextView);
}
И ProgressTextViewTest:
@RunWith(RobolectricUnitTestRunner.class)
@PowerMockIgnore({ "org.mockito.*", "org.robolectric.*", "android.*" })
@PrepareForTest(Formatter.class)
public class ProgressTextViewTest {
@Rule
public PowerMockRule rule = new PowerMockRule();
Activity activity;
@Before
public void beforeTest() {
// PowerMockito
PowerMockito.mockStatic(Formatter.class);
Mockito.when(Formatter.formatFileSize(anyObject(), anyInt())).thenReturn("");
// Robolectic
activity = Robolectric.setupActivity(Activity.class);
}
@Test
public void init_FileDownloaded() {
ProgressTextView progressTextView = new ProgressTextView(activity);
...
}
}
Так что, когда я начать этот тест я получаю следующее исключение:
java.lang.NullPointerException

Если изменить robolectric активности инициализации размещение:
@RunWith(RobolectricUnitTestRunner.class)
@PowerMockIgnore({ "org.mockito.*", "org.robolectric.*", "android.*" })
@PrepareForTest(Formatter.class)
public class ProgressTextViewTest {
@Rule
public PowerMockRule rule = new PowerMockRule();
Activity activity = Robolectric.setupActivity(Activity.class);
@Before
public void beforeTest() {
// PowerMockito
PowerMockito.mockStatic(Formatter.class);
Mockito.when(Formatter.formatFileSize(anyObject(), anyInt())).thenReturn("");
}
@Test
public void init_FileDownloaded() {
ProgressTextView progressTextView = new ProgressTextView(activity);
...
}
}
