Spring Boot单元测试未拾取模拟控制器的请求映射

Question

我正在尝试测试我的控制器，但控制台说找不到模拟请求的URL映射，我可以看到在发射测试＆AMP后，我可以看到控制台上出现的动态映射;他们被映射到各自的方法。

在我的设置中，我有一个模拟服务，该服务被注入了我要测试的控制器中。

这是Test WebApp配置

package com.example.persistance;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.when;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import com.example.dao.UserDao;
import com.example.model.User;
@Configuration
@ComponentScan("com.example")
@EnableWebMvc
class MockWebConfigurationForTest{
    @Bean
    public UserDao setupMockUserDao() {
        User mockUser;
        mockUser=new User();
        mockUser.setId(TestCaseConstants.UserId.uuidAsString());
        mockUser.setAge("24");
        mockUser.setFirstName("Sujal");
        mockUser.setLastName("Mandal");
        mockUser.setUserName("smandal");
        mockUser.setPasswordHash("ABCDE12345");
        UserDao userDao=mock(UserDao.class);
        when(userDao.findOne(TestCaseConstants.UserId.uuidAsString())).thenReturn(mockUser);
        return userDao;
    }
}

这是测试类

package com.example.persistance;
import static org.junit.Assert.assertNotNull;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.MockitoAnnotations;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import com.example.controllers.UserController;
import com.example.model.User;
import com.google.gson.Gson;
@RunWith(SpringRunner.class)
@SpringBootTest
@WebAppConfiguration
@ContextConfiguration(classes = {MockWebConfigurationForTest.class})
public class DataPersistenceServiceApplicationTests {
    MockMvc mockMvc;
    String mockUserId=TestCaseConstants.UserId.uuidAsString();
    User mockUser;
    @InjectMocks
    private UserController userController;
    @Before
    public void setUpTestData() {
        mockUser=new User();
        mockUser.setId(mockUserId);
        mockUser.setAge("24");
        mockUser.setFirstName("Sujal");
        mockUser.setLastName("Mandal");
        mockUser.setUserName("smandal");
        mockUser.setPasswordHash("ABCDE12345");
        MockitoAnnotations.initMocks(this);
        mockMvc=MockMvcBuilders.standaloneSetup(UserController.class).build();
    }
    @Test
    public void testUserController_getOne() throws Exception {
        String result=mockMvc.perform(get("/info")).andReturn().getResponse().getContentAsString();
        assertNotNull(result);
    }
}

进行测试时，我会在控制台中看到以下内容。

正如第二行所说的那样，找不到/info的映射，但是如果您在上方看到一点，您可以看到映射成功地拾取了映射，我缺少什么？

Answer 1

我找到了解决方案，我使用了 mockMvc=MockMvcBuilders.webAppContextSetup(webApplicationContext).build();

而不是standaloneSetup()我使用了webApplicationContext的自动实例

package com.example.persistance;
import static org.junit.Assert.assertNotNull;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import org.junit.Before;
import org.junit.Test;

import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;
import com.example.controllers.UserController;
import com.example.model.User;
import com.google.gson.Gson;
@RunWith(SpringRunner.class)
@SpringBootTest
@ContextConfiguration(classes = {MockWebConfigurationForTest.class})
public class DataPersistenceServiceApplicationTests {
    @Autowired
    WebApplicationContext webApplicationContext;
    MockMvc mockMvc;
    String mockUserId=TestCaseConstants.UserId.uuidAsString();
    User mockUser;
    @InjectMocks
    private UserController userController;
    @Before
    public void setUpTestData() {
        mockUser=new User();
        mockUser.setId(mockUserId);
        mockUser.setAge("24");
        mockUser.setFirstName("Sujal");
        mockUser.setLastName("Mandal");
        mockUser.setUserName("smandal");
        mockUser.setPasswordHash("ABCDE12345");
        MockitoAnnotations.initMocks(this);
        mockMvc=MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }
    @Test
    public void testUserController_getOne() throws Exception {
        Gson gson=new Gson();
        System.err.println("Expected: "+gson.toJson(mockUser));
        String result=mockMvc.perform(get("/users/"+mockUserId)).andReturn().getResponse().getContentAsString();
        System.err.println("Returned: "+result);
        assertNotNull(result);
    }
}
