MockMvc。 如何在junit测试中包含自定义对象

Question

I need the JUnit test to check the controller. The method of the controller is called by submit a form. This method receives a filled object EmailDispatchForm form .

Here is a snippet from controller:

@RequestMapping(value={"/sendEmail"}, method=POST)
public String sendEmail(EmailDispatchForm form,Model model ){
    String status = "OK";

    try {
        workFlows.sendEmailAndRecordHistory(form);
    } catch (Exception e) {
        status = "ERROR";
        model.addAttribute("errDescription", e.getCause().getMessage());
        logger.error(e, e);
    } finally {
        model.addAttribute("sentEmailStatus", status);
    }

    return CommonConstants.VIEW_EMAIL_SENT;
}

This is my junit test:

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

    @Autowired
    private WebApplicationContext webApplicationContext;

    private MockMvc mockMvc;

    @Before
    public void setup() {
        mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }

    @Test
    public void testShowEmailForm() throws Exception{
        mockMvc.perform(get("/emailForm")).andExpect(view().name(CommonConstants.VIEW_EMAIL));
    }
}

How you can see, in the controller there is the method sendEmail() , which has two parameter: EmailDispatchForm form , Model model . I have no idea how can I involve this both parameters in junit test to utilize it as ie Mock-Objects.

I would be very thankful for assistance and would like to know about some resources (books) to study the subject of this issue.

Answer 1

The first problem is that you are trying to use GET and acces a POST URL. Your test method should look like this:

  @Test
    public void testShowEmailForm() throws Exception{
        mockMvc.perform(post("/sendEmail")).andExpect(view().name(CommonConstants.VIEW_EMAIL));
    }

Also add @RequestBody in your controller method

public String sendEmail(@RequestBody EmailDispatchForm form,Model model )

To add the form simply add to the test method:

.contentType(MediaType.APPLICATION_JSON)
        .content(json)

Where JSON is the JSON form of the `EmailDispatchForm form` object.

Hope this helps.

so, i found the other solution. It looks like this:

  @Test public void loginUser() throws Exception { LoginForm loginForm = new LoginForm(); loginForm.setPassword("admin"); loginForm.setUserId("admin"); RequestBuilder request = post("/authentication") .flashAttr("loginForm", loginForm); mockMvc .perform(request) .andDo(MockMvcResultHandlers.print()) .andExpect(redirectedUrl("emailForm")); } 

for the method of controller

  @RequestMapping(value={"/authentication"}, method=POST) public String toAuthentication(@ModelAttribute("loginForm")LoginForm loginForm, Model model){ String view ="redirect:emailForm"; // some activity here to take the loginForm and process it return view; }
