目标：在spring Boot项目中使用Junit进行单元测试UserService的方法

分析：

1.添加启动器依赖spring-boot-starter-test

2.编写测试类测试

=====

1.添加启动器依赖spring-boot-starter-test



<!--添加测试依赖启动器-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>


 

2.编写测试类测试



package com.cc8w.home.service;

import com.cc8w.com.cc8w.entity.User;
import com.cc8w.home.mapper.UserMapper;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class UserServiceTest {
    @Autowired
    private UserService userService;

    @Test
    public void queryById(){
        userService.queryById(1);
    }
    @Test
    public void saveUser(){
        userService.saveUser(new User());

    }

}
