问题:

I have this class:

    package controllers;

    import static org.junit.Assert.*;
    import static org.mockito.Mockito.mock;
    import static org.mockito.Mockito.times;
    import static org.mockito.Mockito.verify;
    import static org.mockito.Mockito.when;

    import java.util.HashSet;

    import org.junit.Before;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.mockito.InjectMocks;
    import org.mockito.Mock;
    import org.mockito.MockitoAnnotations;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.test.context.ContextConfiguration;


    import org.springframework.ui.Model;
    import org.springframework.web.context.WebApplicationContext;

    import com.epam.hhsystem.model.candidate.Candidate;
    import com.epam.hhsystem.services.CandidateService;
    import com.epam.hhsystem.web.controllers.CandidateMenuController;
    import org.springframework.test.context.web.WebAppConfiguration;
    import org.springframework.test.context.junit4.*;
    import org.springframework.test.web.servlet.MockMvc;
    import org.springframework.test.web.servlet.ResultActions;
    import org.springframework.test.web.servlet.request.MockHttpServletRequestBuilder;
    import org.springframework.test.web.servlet.setup.MockMvcBuilders;


    import org.springframework.test.web.servlet.request.*;

    import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
    import static org.hamcrest.Matchers.*;
    import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
    import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;


    @ContextConfiguration(locations = { "classpath:/test/BeanConfig.xml" })
    @RunWith(SpringJUnit4ClassRunner.class)
    @WebAppConfiguration
    public class CandidateControllerTest {

        @Mock(name = "candidateService")
        private CandidateService candidateService;

        @InjectMocks
        private CandidateMenuController candidateMenuController = new CandidateMenuController();

        @Autowired
        WebApplicationContext wac;

        MockMvc mockMvc;

        @Before
        public void before() {
            MockitoAnnotations.initMocks(this);
              this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).dispatchOptions(true).build();

        }
@Test 
    public void testgoToCandidateMenuMockMvc() throws Exception { 
        //MockHttpServletRequestBuilder request = MockMvcRequestBuilders.get("/goToCandidateMenu");


        MockHttpServletRequestBuilder request = MockMvcRequestBuilders.get("/goToCandidateMenu");
        ResultActions result = mockMvc.perform(request);
        result.andExpect(status().isOk());
     }
}

When I execute it I see:

Controller code:

@Controller
public class CandidateMenuController extends AbstractController {
...
@RequestMapping("/goToCandidateMenu")
    public String goToCandidateMenu() {
        return "candidateMenu";
    }
...
}

Can you help me to fix my problem?

回答1:

Your test setup is wrong you aren't initializing the MockMvc correctly and that is al clearly in the reference guide. FIrst of all you have twice the initializing code and you aren't assing the result of the call to the build method. So you are basically left with an empty MockMvc object.

@Before
public void before() {
    MockitoAnnotations.initMocks(this);
    MockMvcBuilders.webAppContextSetup(this.wac).dispatchOptions(true).build();
    MockMvcBuilders.webAppContextSetup(this.wac).dispatchOptions(true).build();
}

Should be 

@Before
public void before() {
    MockitoAnnotations.initMocks(this);
    this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).dispatchOptions(true).build();
}

As stated this is all explained in the reference guide.



回答2:

I believe you just haven't enabled <mvc:annotation-driven> in your beanconfig.xml and so your @Controller classes just aren't being registered.

Add this

<mvc:annotation-driven></mvc:annotation-driven>


回答3:

This is my working solution. Hope it helps.

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)
@WebAppConfiguration
public class SimpleTest  {

private MockMvc mockMvc;

@Autowired
private WebApplicationContext webApplicationContext;

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

@Test
public void test() throws Exception {        
    mockMvc.perform(get("/simple")
            .contentType(MediaType.APPLICATION_JSON))
            .andExpect(status().is(200));
    }
}


回答4:

In my case, I was missing the below annotation and was getting this error.

@WebMvcTest(UserStatsController.class)
public class UserStatsControllerTest {
  ..
}

Note that the class of the controller and NOT the test. Make sure as well if you load other class using @ContextConfiguration(NOT the test) not load test class.



回答5:

In the case that you make a really stupid "going to fast for your own good" typo like I did, make sure that your controller test class does NOT have the same name as the controller class itself. Most people know this, but you can get into this same error condition the names are identical, and it may not my immediately obvious why. To clarify further, make sure you DO NOT DO THIS:

Controller name: MyController
Test class name: MyController

This can cause your MockMvc tests to fail with status 404... which is not very obvious.
Naming [obviously] should be more like:

Controller name: MyController
Test class name: MyControllerTest



回答6:

I added this annotations to configuration class and work it:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = AnnotationConfigWebContextLoader.class)
@WebAppConfiguration
public class ResourceTest {

   ...

   @Configuration
   @EnableWebMvc
   @ComponentScan( basePackages = { "..." } )
   static class ContextConfiguration {
   }
}


回答7:

My problem was I did not have @ComponentScan() it was pretty embarrassing. It was also hard to find.I,myself overlooked my SpringBootApplication.
