第四章 SpringBoot2.0单元测试进阶实战和自定义异常处理

03-2 SpringBoot测试进阶高级篇之MockMvc讲解

简介:讲解MockMvc类的使用和模拟Http请求实战
		1、增加类注解 @AutoConfigureMockMvc
					@SpringBootTest(classes={XdclassApplication.class})
		2、相关API
			perform：执行一个RequestBuilder请求
			andExpect：添加ResultMatcher->MockMvcResultMatchers验证规则
			andReturn：最后返回相应的MvcResult->Response

在spring boot项目中新建一个JuitController类。提供一个接口以便之后做Mock测试。

1.JunitController类

package com.lcz.spring_demo5.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

/**

 * @Description:
 **/
@RestController
public class JUnitController {
    @GetMapping(value = "/test_junit")
    public String testJUnit(){
        return "JUnit Test";
    }
}

2.MockMvcTestDemo.java

package com.lcz.spring_demo5;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MvcResult;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;

/**
 * @author : codingchao
 * @date : 2021-11-18 22:57
 * @Description:
 **/
@RunWith(SpringRunner.class)
@SpringBootTest(classes = {SpringDemo5Application.class}) //底层用junit
@AutoConfigureMockMvc
public class MockMvcTestDemo {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void apiTest() throws Exception {

        MvcResult mvcResult =  mockMvc.perform( MockMvcRequestBuilders.get("/test_junit") ).
                andExpect( MockMvcResultMatchers.status().isOk() ).andReturn();
        int status = mvcResult.getResponse().getStatus();
        System.out.println(status);

    }
}

测试结果
