写一个springboot的测试用例

package com.cn.thinkchen.springbootjpa.test;

import com.cn.thinkchen.springbootjpa.SpringbootjpaApplication;
import com.cn.thinkchen.springbootjpa.dao.UserDao;
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.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.transaction.annotation.Transactional;
    
@RunWith(SpringJUnit4ClassRunner.class)              //就是指用SpringJUnit4ClassRunner来运行
@WebAppConfiguration                                    //申明这是一个测试
@SpringBootTest(classes=SpringbootjpaApplication.class)//引入springboot的入口
@Transactional                                        //开启事务
public class d {
    @Autowired                                    //自动注入
    private UserDao dao;    
    @Test                                        //开启测试
    public void dd(){
        System.out.println(dao.findAll().toString());    
    }
}

以上就是springbboot的测试用例

运行结果如下
