嘗試測驗存盤庫方法，但我的測驗失敗并出現以下“想要但未呼叫：cellphonesDao.deleteAllCellphones();” 這是回購方法：
@Override
public Single<Cellphone[]> getCellphones() {
Single<CellPhoneEntity[]> remoteCellphones =
networkModule.productApi()
.getCellPhones()
.onErrorResumeNext(cellphonesDao.getAllCellphones()); // todo return value if true
Single<CellPhoneEntity[]> localCellphones = cellphonesDao.getAllCellphones();
return Single.zip(remoteCellphones, localCellphones, (remote, local) -> {
if (!Arrays.equals(remote, local)) {
cellphonesDao.deleteAllCellphones();
for (CellPhoneEntity cellPhoneEntity : remote) {
cellphonesDao.insertCellphone(cellPhoneEntity);
}
}
return mapper.toCellphones(remote);
});
}
主要目的是以正確的方式測驗回購方法。猜猜我選擇的方式不好。這是測驗實作：
class CellPhoneRepositoryImplTest {
NetworkModule networkModule;
CellphonesDao cellphonesDao;
CellphoneMapper cellphoneMapper;
CellPhoneRepositoryImpl cellPhoneRepository;
ProductAPI productAPI;
@BeforeEach
void setUp() {
networkModule = Mockito.mock(NetworkModule.class);
cellphonesDao = Mockito.mock(CellphonesDao.class);
productAPI = Mockito.mock(ProductAPI.class);
cellphoneMapper = new CellphoneMapper();
cellPhoneRepository = Mockito.spy(new CellPhoneRepositoryImpl(
networkModule,
cellphonesDao,
cellphoneMapper
));
}
@Test
void whenRemoteDataAreDifferentFromLocalDbIsUpdated() {
int numberOfCellphones = 5;
CellPhoneEntity[] remoteCellphones = DummyCellphoneEntityFactory.generateCellphones(numberOfCellphones);
CellPhoneEntity[] localCellphones = DummyCellphoneEntityFactory.generateCellphones(numberOfCellphones);
Mockito.when(networkModule.productApi()).thenReturn(productAPI);
Mockito.when(networkModule.productApi().getCellPhones()).thenReturn(wrapWithSingle(remoteCellphones));
// Mockito.when(networkModule.productApi().getCellPhones().onErrorResumeNext(cellphonesDao.getAllCellphones())).thenReturn(wrapWithSingle(remoteCellphones));
Mockito.when(cellphonesDao.getAllCellphones()).thenReturn(wrapWithSingle(localCellphones));
Mockito.doNothing().when(cellphonesDao).deleteAllCellphones();
cellPhoneRepository.getCellphones();
Mockito.verify(cellphonesDao, Mockito.times(1))
.deleteAllCellphones();
}
private Single<CellPhoneEntity[]> wrapWithSingle(CellPhoneEntity[] cellphones) {
return Single.just(cellphones);
}
}
我會很高興有任何建議）
uj5u.com熱心網友回復：
回傳的代碼Single不會立即執行，但您的驗證會。嘗試呼叫cellPhoneRepository.getCellphones().blockingGet()而不是僅僅呼叫cellPhoneRepository.getCellphones(). 應該讓您的blockingGet()測驗等到 Single 完成執行。
