pom.xml配置

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

测试代码：

首先，在src目录下建立test/java包。

1. 对UserService（业务方法）进行测试

package com.xxxx.springboot.service;


import com.xxxx.springboot.Starter;
import org.junit.After;
import org.junit.Before;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import javax.annotation.Resource;

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {
          
   Starter.class})
class UserServiceTest {
          
   
    @Resource
    private UserService userService;

    private Logger log = LoggerFactory.getLogger(UserServiceTest.class);

    @Before
    public void before(){
          
   
        log.info("单元测试开始");
    }

    @Test
    public void test01(){
          
   
        log.info("用户记录：[{}]",userService.queryById(1));
    }

    @Test
    public void test02(){
          
   
        log.info("用户记录:{}",userService.queryUserByUserName("admin"));
    }



    @After
    public void after(){
          
   
        log.info("单元测试结束");
    }

    @Test
    void contextLoads() {
          
   
    }

}

2. 对UserController(控制层接口）进行测试

package com.xxxx.springboot.controller;


import com.xxxx.springboot.Starter;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
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;

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {
          
   Starter.class})
@AutoConfigureMockMvc
public class UserControllerTest {
          
   
    private Logger log = LoggerFactory.getLogger(UserControllerTest.class);

    @Autowired
    private MockMvc mockMvc;

    @Before
    public void before(){
          
   
        log.info("单元测试开始");
    }

    @After
    public void after(){
          
   
        log.info("单元测试结束");
    }

    @Test
    public void test01() throws Exception{
          
   
        MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.get("/user/username/admin"))
                .andExpect(MockMvcResultMatchers.status().isOk()).andReturn();
        log.info("响应状态：{}",mvcResult.getResponse().getStatus());
        log.info("响应结果：{}",mvcResult.getResponse().getContentAsString());
    }

    @Test
    public void test02() throws Exception{
          
   
        MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.get("/user/list?userName=admin"))
                .andExpect(MockMvcResultMatchers.status().isOk()).andReturn();
        log.info("响应状态：{}",mvcResult.getResponse().getStatus());
        log.info("响应结果：{}",mvcResult.getResponse().getContentAsString());
    }

}
