EasyMock控制器映射和狀態代碼測試

Question

我試圖測試我的控制器映射和響應http狀態代碼。因此，我正在使用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(); 
    } 
} 

和我的測試類：

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); 
    } 
} 

但是我卻越來越在行對象處理的NullPointerException異常= ...

我只是想測試我的映射，然後檢查我的響應中的HTTP狀態代碼。這是正確的方法還是我的測試實施完全錯誤？對於我需要使用EasyMock的測試。下一步我想測試響應狀態碼（response.getStatus（））是否等於SC_OK（200）。

THX任何幫助:)

我用SpringMVC使用的測試方法，用EasyMock的，這是一個很好的方法混合。

@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);
