Service层的怎么写测试类

给出具体代码

 代码部分

package com.java.service;

/**
 * @Description:
 * @Author: qiuxie
 * @Create: 2024/4/12 0:26
 */
public interface TestService {

    void test();
}


package com.java.service;

import org.springframework.stereotype.Service;

/**
 * @Description:
 * @Author: qiuxie
 * @Create: 2024/4/12 0:26
 */
@Service
public class TestServiceImpl implements TestService{
    @Override
    public void test() {
        System.out.println("service测试.....");
    }
}

　　启动类

package com.java;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @Description:  设置年轻代和老年代的比例  1:4
 * E:S0:S1  8:1:1
 * @Author: Yourheart
 * @Create: 2023/4/21 11:27
 */
@SpringBootApplication()
public class MysqlServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(MysqlServiceApplication.class, args);
    }

}

　　无任何配置文件

测试类代码

package com.java;

import com.java.service.TestService;
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;

/**
 * @Description:
 * @Author: qiuxie
 * @Create: 2024/4/12 0:27
 */
@RunWith(SpringRunner.class)
@SpringBootTest
public class Tests {

    /**
     * 这里做对象的声明
     */
    @Autowired
    private TestService testService;

    @Test
    public void test(){
        testService.test();
    }

}

　　最后给出pom文件

<?xml version="1.0" encoding="UTF-8"?>
