В настоящее время я пишу модульный тест для метода ниже
@Autowired
private RequestConfig requestConfig;
@Autowired
private RetryTemplate retryTemplate;
public ResponseEntity<String> makeGetServiceCall(String serviceUrl) throws Exception {
try {
return retryTemplate.execute(retryContext -> {
RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = requestConfig.createHttpHeaders();
HttpEntity<String> entity = new HttpEntity<String>("parameters", headers);
ResponseEntity<String> response = restTemplate.exchange(serviceUrl, HttpMethod.GET, entity, String.class);
return response;
});
} catch (Exception e) {
throw new Exception("Generic exception while makeGetServiceCall due to" + e + serviceUrl);
}
}
ОБНОВЛЕННЫЙ МЕТОД:
@Autowired
private RequestConfig requestConfig;
@Autowired
private RetryTemplate retryTemplate;
@Autowired
private RestTemplate restTemplate;
public ResponseEntity<String> makeGetServiceCall(String serviceUrl) throws Exception {
try {
return retryTemplate.execute(retryContext -> {
HttpHeaders headers = requestConfig.createHttpHeaders();
HttpEntity<String> entity = new HttpEntity<String>("parameters", headers);
ResponseEntity<String> response = restTemplate.exchange(serviceUrl, HttpMethod.GET, entity, String.class);
return response;
});
} catch (Exception e) {
throw new Exception("Generic exception while makeGetServiceCall due to" + e + serviceUrl);
}
}
Я испробовал все возможности, но не смог сделать это правильно.Вот мой нижеприведенный тест.
@Mock
private RestTemplate restTemplate;
@Mock
public RequestConfig requestConfig;
@InjectMocks
private RetryTemplate retryTemplate;
ServiceRequest serviceRequest;
@Test
public void makeGetServiceCall() throws Exception {
String url = "http://localhost:8080";
RetryTemplate mockRetryTemplate = Mockito.mock(RetryTemplate.class);
RestTemplate mockRestTemplate = Mockito.mock(RestTemplate.class);
ResponseEntity<String> myEntity = new ResponseEntity<>(HttpStatus.ACCEPTED);
Mockito.when(mockRetryTemplate.execute(ArgumentMatchers.any(RetryCallback.class), ArgumentMatchers.any(RecoveryCallback.class), ArgumentMatchers.any(RetryState.class))).thenReturn(myEntity);
Mockito.when(mockRestTemplate.exchange(
ArgumentMatchers.eq(url),
ArgumentMatchers.eq(HttpMethod.GET),
ArgumentMatchers.<HttpEntity<String>>any(),
ArgumentMatchers.<Class<String>>any())
).thenReturn(myEntity);
ResponseEntity<String> response = serviceRequest.makeGetServiceCall(url);
Assert.assertEquals(myEntity, response);
}
ОБНОВЛЕННЫЙ ДЕЛО ТЕСТА:
@Mock
public RequestConfig requestConfig;
@Mock
private RestTemplate restTemplate;
@Mock
private RetryTemplate retryTemplate;
@InjectMocks
ServiceRequest serviceRequest;
@Test
public void makeGetServiceCall() throws Exception {
//given:
String url = "http://localhost:8080";
when(requestConfig.createHttpHeaders()).thenReturn(null);
ResponseEntity<String> myEntity = new ResponseEntity<>( HttpStatus.ACCEPTED);
when(retryTemplate.execute(any(RetryCallback.class), any(RecoveryCallback.class), any(RetryState.class))).thenAnswer(invocation -> {
RetryCallback retry = invocation.getArgument(0);
return retry.doWithRetry(/*here goes RetryContext but it's ignored in ServiceRequest*/null);
});
when(restTemplate.exchange(anyString(), any(HttpMethod.class), any(HttpEntity.class), eq(String.class)))
.thenReturn(myEntity);
//when:
ResponseEntity<String> response = serviceRequest.makeGetServiceCall(url);
//then:
assertEquals(myEntity, response);
}
Объект ответа, который я получаю из моего вызова метода makeGetServiceCall
, всегда возвращает ноль.Когда я отлаживаю код, я вижу исключение org.mockito.exceptions.misusing.WrongTypeOfReturnValue: ResponseEntity cannot be returned by toString() toString() should return String
ошибка при resttemplate
макете, где я возвращаю myEntity
Я не уверен, что мне не хватает.
