Springboot如何集成Junit4呢?

Springboot集成Junit4的实现思路
     1.引入相应的jar包
	 2.添加相应的注解
	    @RunWith(SpringJUnit4ClassRunner.class)
        @SpringBootTest(classes = 启动类.class)
	 3.方法中即可使用相应的类进行测试

//一、引入依赖

 <dependency>
	<groupId>junit</groupId>
	<artifactId>junit</artifactId>
	<version>4.12</version>
</dependency>
<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-test</artifactId>
	<scope>test</scope>
</dependency>


//二、在test文件夹下编写测试类

package com.java265;

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;
 
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = 启动类.class)
public class TestClassService {
    @Autowired
    TestService testService;
 
    @Test
    public void test(){
        Boolean aBoolean = test.updateStatus(9L, "5");
        System.out.println(aBoolean);
    }
}
