Question

我想测试控制器方法是否返回http status 200

package pl.azimuthit.flightmap.service.module.route.util.alert;

...

@Slf4j
@Controller
public class FlightAcknowledgeAlertsServiceImpl implements FlightAcknowledgeAlertsService {

    ...

    @Override
    @RequestMapping(value = SERVICE_MAPPING, method = POST)
    public @ResponseBody
    ResponseEntity acknowledgeAlert(@PathVariable(ALERT_ID) String alertId) {

        ....

        try {
            Map.Entry<AlertID, AlertJTO> entry = alertsCache.findUserEntryById(alertId, userLogin);
            ...
            return new ResponseEntity(HttpStatus.OK);
        } catch (Exception ex) {
            ...
            return new ResponseEntity(HttpStatus.BAD_REQUEST);
        }
    }
}

我模拟了alertCache并添加了when()，它设置了findUserEntryById以返回给定的条目。不幸的是，它返回一个null，不知道为什么，这将在以后抛出null并捕获“捕获”。问题是，尽管设置了应返回的内容，为什么它仍返回null。结果是http代码400，而不是200。无论传递什么，我都希望正确传递所有内容。

public Map.Entry<AlertID, AlertJTO> findUserEntryById(String alertId, String userLogin) {
        return alertJTOCache.entrySet()
                .stream()
                .filter(key -> key.getKey()
                        .getUserLogin()
                        .equals(userLogin))
                .filter(entry -> entry.getValue()
                        .getId()
                        .equals(alertId))
                .findFirst()
                .orElse(null);
    }

测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "..." })
@WebAppConfiguration
 public class FlightAcknowledgeAlertsServiceImplTest {

private static final String ALERT_ID = "123";

...

private MockMvc mockMvc;

@Before
public void init() {
    MockitoAnnotations.initMocks(this);
    mockMvc = MockMvcBuilders.webAppContextSetup(webContext)
            .build();
}
   ...


 @Test
public void testAcknowledgeOfExistingAlert() throws Exception {
    //given
    UserData userData = mock(UserData.class);
    AlertID alertID = mock(AlertID.class);
    AlertJTO alertJTO = mock(AlertJTO.class);

    Map.Entry<AlertID, AlertJTO> entry = new AbstractMap.SimpleEntry<>(alertID, alertJTO);
    //when
    when(flightmapUserContext.getUserData()).thenReturn(userData);
    when(alertsCache.findUserEntryById(any(),any())).thenReturn(entry);
    //then
    mockMvc.perform(MockMvcRequestBuilders.post(url(), ALERT_ID)
            .param(FlightAcknowledgeAlertsService.ALERT_ID, ALERT_ID))
            .andExpect(MockMvcResultMatchers.status()
                    .isOk());
}

Answer 1

我认为你失踪了

@InjectMocks
    FlightAcknowledgeAlertsServiceImpl controllerUnderTest;

所以控制器实例不会得到模拟。

@MockBean

然后执行正常的when / thenReturn事情。

尽管有`when（）`方法，它仍返回null
