Я пытаюсь написать тестовый пример Junit для одного из классов.Но получая ошибку при попытке сделать это,
Тестовый класс выглядит следующим образом -
public class IntegratorClassTest{
@InjectMocks
IntegratorClass integratorClass;
@Mock
RequestClass requestClass;
@Mock
ContentList contentResponse;
@Before
public void setUp() throws Exception {
MockitoAnnotations.initMocks(this);
}
@Test
public void getCmsOffersTest()throws Exception{
ContentService contentService = Mockito.mock(ContentService.class);
RequestClass requestClass = Mockito.mock(RequestClass.class);
ContentList contentResponse = getContentList();
when(contentService.getContentCollection()).thenReturn(contentResponse);
Validator validator = Mockito.mock(Validator.class);
List<OfferDetails> offerList = new ArrayList<OfferDetails>();
Mockito.doNothing().when(validator).validateData(offerList);
List<OfferDetails> offerListResult = integratorClass.getCmsOffers(contentService, requestClass);
assertTrue(offerListResult.size()>0);
}
}
А класс реализации выглядит примерно так:
public class IntegratorClass {
private static final Logger LOGGER = LoggerFactory.getLogger(IntegratorClass.class);
@Autowired
Validator validator;
public List<OfferDetails> getCmsOffers(ContentService contentService,RequestClass requestClass)throws Exception{
LOGGER.info("Entered method getCmsOffers to get the list of offers from CMS");
List<OfferDetails> offerList = new ArrayList<OfferDetails>();
ContentList contentResponse = null;
try
{
contentResponse = contentService.getContentCollection();
offerList = getOfferListFromCmsResponse(contentResponse, requestClass);
LOGGER.info("Total number of active offers we got from CMS are -" + offerList.size());
}catch (Exception e)
{
ErrorResponse errorResponse = PromotionalOffersUtilities.createErrorResponse("500", e.getMessage(),"Getting error while fetching content from CMS - getCmsOffers", ErrorResponse.Type.ERROR);
LOGGER.error("Getting error while fetching content from CMS with Error Message: " + e.getMessage());
throw new ServiceException(errorResponse, HttpStatus.INTERNAL_SERVER_ERROR);
}
//failing here
validator.validateData(offerList);
LOGGER.info("Exiting method getCmsOffers");
return offerList;
}
}
Когда язапустил его в режиме отладки am ошибка для строки validator.validateData(offerList);
.
Возвращается "NullPointerException
".
