Spring-Test-Mvc Controller Tests

Question

I'm using spring-test-mvc (standalone) because my application runs with spring 3.1. I'm basically just trying to test my controller methods and the response HTTP codes.

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class})
public class AdminSpringControllerTests {
    private AdminSpringController cut;
    private MockMvc mockMvc;
    public AdminSpringControllerTests() {

        cut = new AdminSpringController();
        this.mockMvc = MockMvcBuilders.standaloneSetup(cut).build();
    }
    @Test
    public void testGetUsers_Sc200_1() throws Exception{

        List<User> users = new ArrayList<User>();
        for (int i = 1; i<3; i++) {
            User user = new User();
            user.setId(i);
            user.setUserId("test"+i);
            user.setName("Max Testermann");

            users.add(user);
        }

        EasyMock.expect(cut.userService.getUsers()).andReturn(users);
        EasyMock.replay();

        MockHttpServletRequestBuilder request = MockMvcRequestBuilders.get("/user");

        this.mockMvc.perform(request).andExpect(MockMvcResultMatchers.status().isOk());

        EasyMock.verify(cut);

    }
}

But I'm getting an NoSuchMethodError

java.lang.NoSuchMethodError: org.springframework.web.servlet.FlashMapManager.saveOutputFlashMap(Lorg/springframework/web/servlet/FlashMap;Ljavax/servlet/http/HttpServletRequest;Ljavax/servlet/http/HttpServletResponse;)V
    at org.springframework.test.web.server.request.MockHttpServletRequestBuilder.buildRequest(MockHttpServletRequestBuilder.java:605)
    at org.springframework.test.web.server.MockMvc.perform(MockMvc.java:125)
    at com.prime_sign.admin.web.controller.AdminSpringControllerTests.testGetUsers_Sc200_1(AdminSpringControllerTests.java:98)

Is it necessary to @Autowire my Controller? Is my constructor wrong ? There is a context file in src/test/resources/"package-path"/AdminSpringControllerTests-context.xml but it only contains <context:annotation-config /> and <tx:annotation-driven /> , do I have to inject my controller bean there (question 1, is it necessary).

Thx for any help :)

// EDIT

I updated my code:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
public class AdminSpringControllerTests {

    private MockMvc mockMvc;

    @Autowired
    private WebApplicationContext wac;

    public AdminSpringControllerTests() {
        this.mockMvc = MockMvcBuilders.webApplicationContextSetup(this.wac).build();
    }

    @Test
    public void testGetUsers_Sc200_1() throws Exception{

        List<User> users = new ArrayList<User>();
        for (int i = 1; i<3; i++) {
            User user = new User();
            user.setId(i);
            user.setUserId("test"+i);
            user.setName("Max Testermann");

            users.add(user);
        }

        EasyMock.expect(cut.userService.getUsers()).andReturn(users);
        EasyMock.replay();

        MockHttpServletRequestBuilder request = MockMvcRequestBuilders.get("/user").accept(MediaType.APPLICATION_JSON);

        this.mockMvc.perform(request).andDo(print()).andExpect(MockMvcResultMatchers.status().isOk());

        EasyMock.verify(cut);

    }
}

But know I have the problem that (I think), I'm not getting the WebApplicationContext right:

java.lang.IllegalArgumentException: WebApplicationContext is required
    at org.springframework.util.Assert.notNull(Assert.java:112)
    at org.springframework.test.web.server.setup.InitializedContextMockMvcBuilder.<init>(InitializedContextMockMvcBuilder.java:39) 

Answer 1

you are using standaloneSetup and create your controller by using new AdminSpringController(); so spring doesnt have any control over it. Using standaloneSetup is more convenient to test just one controller at once, without any connection to filters/interceptors etc... which is probably not what you are looking for. Try to use webAppContextSetup instead:

....
 @Autowired
private WebApplicationContext wac;

@BeforeClass
public void setUp(){
    mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
}

this way it should use your spring configuration.
