Spring-Test-Mvc控制器测试

Question

我使用的是spring (独立的)，因为我的应用程序运行在Spring3.1中。我基本上只是试着测试我的控制器方法和响应HTTP代码。

@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);

    }
}

但我得到了一个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)

是否有必要@自动更新我的控制器？我的构造函数错了吗？src/test/resources/"package-path"/AdminSpringControllerTests-context.xml中有一个上下文文件，但它只包含<context:annotation-config />和<tx:annotation-driven />，我是否必须将控制器bean注入其中(问题1，是否有必要)。

( Thx寻求任何帮助:)

我更新了代码：

@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);

    }
}

但我知道我有这样的问题(我认为)，我没有正确地理解WebApplicationContext：

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

您正在使用standaloneSetup并使用新的AdminSpringController()创建控制器；因此spring没有对它的任何控制。使用standaloneSetup更方便的是一次只测试一个控制器，没有任何连接到过滤器/拦截器等。这可能不是你要找的。尝试使用webAppContextSetup代替：

....
 @Autowired
private WebApplicationContext wac;

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

这样，它应该使用您的弹簧配置。
