best way to integration test spring mvc

问题

I have a Spring MVC 3.2 project that I would like to unit & integration tests. The problem is all the dependencies I have, makes testing extremely difficult even with Sprint-test.

I have a controller like this:

@Controller
@RequestMapping( "/" )
public class HomeController {

    @Autowired
    MenuService menuService;  // will return JSON

    @Autowired
    OfficeService officeService; 


    @RequestMapping( method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE )
    @ResponseBody
    public AuthenticatedUser rootCall( HttpServletRequest request ) {
        AuthenticatedUser authentic = new AuthenticatedUser();

        Office office = officeService.findByURL(request.getServerName());
        authentic.setOffice(office);

        // set the user role to authorized so they can navigate the site
        menuService.updateVisitorWithMenu(authentic);
        return returnValue;
     }

This will return a JSON object. I would like to test this call returns a 200 and the correct object with canned JSON. However, I have a lot of other classes called by those @Autowired classes, and even if I mock them like this:

 @Bean public MenuRepository menuRepository() {  
      return Mockito.mock(MenuRepository.class); 
 }

this creates a lot of mocked classes. Here is how I am trying to test it:

 @RunWith( SpringJUnit4ClassRunner.class )
 @ContextConfiguration( classes = JpaTestConfig.class )
 @WebAppConfiguration
 public class HomeControllerTest {

     private EmbeddedDatabase database;

    @Resource
    private WebApplicationContext webApplicationContext;

    @Autowired
    OfficeService officeService;

    private MockMvc mockMvc;

    @Test
    public void testRoot() throws Exception {  mockMvc.perform(get("/")).andDo(print()).andExpect(status().isOk())
      .andExpect(content().contentType(IntegrationTestUtil.APPLICATION_JSON_UTF8))
            .andExpect(content().string(<I would like canned data here>));

}

I can go thru and setup a H2 embeddeddatabase and populate it, but I wonder if that is really a test of this controller or the application? Can anyone recommend some better approaches to this integration test? How does one write unit tests for controllers?

Thank you!

Check out the spring show case project and take a look at controller test cases you will be able to understand and see standard way of testing controllers. MappingControllerTests.java has some json based controller testing
