Spring整合JUnit

说明：Spring整合JUnit是指将Spring框架与JUnit测试框架相结合，以便在测试过程中能够利用Spring的功能和特性。

1.导入依赖

2. 配置

3.装配bean

   //支持自动装配注入bean
    @Autowired
    private AccountService accountService;

    @Test
    public void testFindById(){
        System.out.println(accountService.findById(1));

    }

4.源码

package com.itheima.service;

import com.itheima.config.SpringConfig;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
//设置类运行器  专用运行器
@RunWith(SpringJUnit4ClassRunner.class)
//设置Spring环境对应的配置类
@ContextConfiguration(classes = SpringConfig.class)
public class AccountServiceTest {
    //支持自动装配注入bean
    @Autowired
    private AccountService accountService;

    @Test
    public void testFindById(){
        System.out.println(accountService.findById(1));

    }

    @Test
    public void testFindAll(){
        System.out.println(accountService.findAll());
    }


}
