一、写在前面

本文在 SpringBoot之集成JUnit5进行单元测试 一文基础上进行拓展延伸，实现对 Controller 类的测试。

二、创建项目集成 JUnit 5 测试 Controller

1.项目说明

本项目在 SpringBoot之集成JUnit5进行单元测试 一文创建的项目 junit 基础上进行修改完善，实现对 Controller 类的测试。

2.修改测试类 LoginControllerTest

修改注意事项：
（1）添加 @AutoConfigureMockMvc
（2）实现 setupMockMvc() 方法并添加注解 @BeforeEach

完整代码如下：

@SpringBootTest
@AutoConfigureMockMvc
class LoginControllerTest {

    @Autowired
    private MockMvc mvc;

    private MockHttpSession session;

    @BeforeEach
    public void setupMockMvc() {
        session = new MockHttpSession();
    }

    @Test
    void getUserInfo() throws Exception{
        MvcResult mvcResult = (MvcResult) mvc.perform(MockMvcRequestBuilders.get("/user/getUserInfo")
        .accept(MediaType.ALL)
        .session(session))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andDo(MockMvcResultHandlers.print())
                .andReturn();
        int status = mvcResult.getResponse().getStatus();
        String content = mvcResult.getResponse().getContentAsString();
        System.out.println(content);
    }
}

3.运行测试

运行后可在控制台看到以下信息：

MockHttpServletRequest:
      HTTP Method = GET
      Request URI = /user/getUserInfo
       Parameters = {}
          Headers = [Accept:"*/*"]
             Body = null
    Session Attrs = {}

Handler:
             Type = com.chaoyue.junit.controller.LoginController
           Method = com.chaoyue.junit.controller.LoginController#getUserInfo()

Async:
    Async started = false
     Async result = null

Resolved Exception:
             Type = null

ModelAndView:
        View name = null
             View = null
            Model = null

FlashMap:
       Attributes = null

MockHttpServletResponse:
           Status = 200
    Error message = null
          Headers = [Content-Type:"text/plain;charset=UTF-8", Content-Length:"43"]
     Content type = text/plain;charset=UTF-8
             Body = User(id=1, username=admin, password=123456)
    Forwarded URL = null
   Redirected URL = null
          Cookies = []
User(id=1, username=admin, password=123456)
