简介

开发一个优秀的系统，单元测试也是必不可少的，Spring Boot 对单元测试也做了一些支持，MockMVC就是之一，可以模拟web端的post，get请求，测试也能得到详细的过程

使用方法

添加依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

编写测试代码

@SpringBootTest
public class Springboot13StarterTestApplicationTests {

    private MockMvc mockMvc;

    //初始化资源
    @Before
    public void setMockMvc() throws Exception{
        mockMvc= MockMvcBuilders.standaloneSetup(new HelloController()).build();
    }

    @Test
    public void test() throws Exception{
        mockMvc.perform(MockMvcRequestBuilders.post("/hello?name=低调小熊猫")
                .accept(MediaType.APPLICATION_JSON_UTF8)).andDo(print());
    }
    @Test
    public void test2() throws Exception{
        mockMvc.perform(MockMvcRequestBuilders.post("/hello?name=低调小熊猫")
                .accept(MediaType.APPLICATION_JSON_UTF8))
                .andExpect(MockMvcResultMatchers.content().string(Matchers.containsString("低调小熊猫")));

    }
    @Test
    public void contextLoads() {
        System.out.println("低调小熊猫");
    }

}

代码作用accept(MediaType.APPLICATIONJSONUTF8)) 设置编码格式 andDo(print()) //会将请求和相应的过程都打印出来 Matchers.containsString("str")，判断返回的结果集中是否包含“str”这个字符串

运行测试

我们运行第一个test

MockHttpServletRequest:
      HTTP Method = POST
      Request URI = /hello
       Parameters = {name=[低调小熊猫]}
          Headers = {Accept=[application/json;charset=UTF-8]}
             Body = <no character encoding set>
    Session Attrs = {}

Handler:
             Type = com.hope.controller.HelloController
           Method = public java.lang.String com.hope.controller.HelloController.hello(java.lang.String)

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=[application/json;charset=UTF-8], Content-Length=[21]}
     Content type = application/json;charset=UTF-8
             Body = 你好低调小熊猫
    Forwarded URL = null
   Redirected URL = null
          Cookies = []
