Junit 测试用例失败 400 错误请求

Question

我在 spring data jpa 应用程序中使用 junit 进行单元测试。我正在尝试为控制器 class unclaimedRoomAssign() 编写 junit 测试用例。我正在使用 mockito 创建模拟对象。

我尝试编写如下测试，但收到测试失败 400 错误请求。谁能告诉我我在测试用例中遗漏了什么

RoomDepartmentMappingController class

   public class RoomDepartmentMappingController {

    @Autowired
    RoomDepartmentMappingService rdmService;

    @PostMapping("/assignUnclaimedRooms")
    public ResponseEntity<String> unclaimedRoomAssign(@NotNull  @RequestParam(name="nDeptId", required= true) Integer nDeptId,
                                                      @NotNull  @RequestParam(name="nRoomId" , required = true) Integer nRoomId,
                                                      @Nullable @RequestParam(name="nSubDeptId" , required = false) Integer nSubDeptId){

        return ResponseEntity.ok(rdmService.unclaimedRoomAssign(nDeptId, nRoomId,nSubDeptId ));

}

TestRoomDepartmentMappingControllerclass

@RunWith(SpringRunner.class)
@ContextConfiguration(classes = RoomDepartmentMappingController.class)
@WebMvcTest(value = RoomDepartmentMappingController.class)
public class TestRoomDepartmentMappingController {

    @Autowired
    private MockMvc mockMvc;

    @MockBean
    RoomDepartmentMappingService roomDepartmentMappingService;

    @Value("${InstituteIdentifier}")
    String instituteIdentifier;

    @Test
    public void UnclaimedRoomAssignTest() throws Exception {

        String stringUrl="/spacestudy/"+ instituteIdentifier+"/asset/room/assignUnclaimedRooms";

        String stringResult = "Room assign sucessfully";        

        Department dep = new Department();
        dep.setnDeptId(1);


        RoomDepartmentMapping rdmObj = new RoomDepartmentMapping();     
                              rdmObj.setnRoomAllocationId(587050);
                              rdmObj.setnDeptId(1);
                              rdmObj.setnRoomId(1215783);

        String inputInJson = mapToJson(rdmObj);     

        Mockito.when(roomDepartmentMappingService.unclaimedRoomAssign(1, 1215783, 0)).thenReturn(stringResult);         

        mockMvc.perform(post(stringUrl)
               .accept(MediaType.APPLICATION_JSON)
               .content(inputInJson)
               .contentType(MediaType.APPLICATION_JSON))
               .andExpect(status().isOk());


     Mockito.verify(roomDepartmentMappingService).unclaimedRoomAssign(1, 1215783, 0);
    }

    private String mapToJson(Object object) throws JsonProcessingException {
        ObjectMapper mapper = new ObjectMapper();
        return mapper.writeValueAsString(object);

    }
}

Answer 1

您有所需的 RequestParams：

@NotNull  @RequestParam(name="nDeptId", required= true) Integer nDeptId,
@NotNull  @RequestParam(name="nRoomId" , required = true) Integer nRoomId,

但是您的请求中没有它们URL

/spacestudy/vcufy2010/asset/room/assignUnclaimedRooms

这应该是这样的

/spacestudy/vcufy2010/asset/room/assignUnclaimedRooms?nDeptId=x&nRoomId=x

其中 x 应该是正确的 ID
