EasyMock 控制器映射和状态码测试

Question

我正在尝试测试我的控制器映射和响应 http 状态代码。因此，我使用的是 RequestMappingHandlerAdapter 和 RequestMappingHandlerMapping。

我的控制器

@Controller
@RequestMapping(value ="/user")
public class AdminSpringController {

    @Autowired
    public UserAdminService userService;

    private final Logger log = LoggerFactory.getLogger(AdminSpringController.class);

    @RequestMapping(method = RequestMethod.GET, consumes = "application/json", produces = "application/json")
    @ResponseStatus(HttpStatus.OK)
    public List<User> getUsers() {

        log.trace("Request to get all users.");

        return userService.getUsers();
    }
}

还有我的测试课：

public class AdminSpringControllerTests {

    AdminSpringController cut;

    private MockHttpServletRequest request;
    private MockHttpServletResponse response;
    private RequestMappingHandlerAdapter adapter;
    private RequestMappingHandlerMapping handlerMapping; 

    @Test
    public void testGetSc() throws Exception{

        adapter = new RequestMappingHandlerAdapter();
        handlerMapping = new RequestMappingHandlerMapping();

        MockHttpServletRequest request = new MockHttpServletRequest();
        request.setMethod("GET");
        request.setRequestURI("/user");
        request.addHeader("Accept", "application/json");

        MockHttpServletResponse response = new MockHttpServletResponse();

        Object handler = handlerMapping.getHandler(request).getHandler();

        ModelAndView mav = adapter.handle(request, response, handler);

        assertNotNull(mav);
    }
}

但我在 Object handler = ... 行中收到 NullPointerException

我只是想测试我的映射，然后从我的响应中检查 HTTP 状态代码。这是正确的方法还是我的测试实现完全错误。对于我需要使用 EasyMock 的测试。作为下一步，我想测试响应状态代码 (response.getStatus()) 是否等于 SC_OK (200)。

感谢任何帮助:)

我正在使用 SpringMvc 测试方法，与 EasyMock 混合使用，这是一个很好的方法。

@ContextConfiguration("ProjectFacadeTest-context.xml")
@RunWith(SpringJUnit4ClassRunner.class)
public class AdminSpringControllerTests {
...
private MockMvc mockMvc;
...
@Before
public void setUp() {
    this.mockMvc = MockMvcBuilders.standaloneSetup(imageController).build();
}

EasyMock.expect(mockPersistedProjectService.getImages(EasyMock.anyLong())).andReturn(images);
EasyMock.replay(mockPersistedProjectService);
    MvcResult result =
            this.mockMvc.perform(get("/resources/projects/1000/images")).andExpect(content().type("application/json"))
                    .andExpect(status().isOk()).andReturn();
MockHttpServletResponse response = result.getResponse();
//VERIFY RESPONSE
EasyMock.verify(mockPersistedProjectService);
