2024.12.20（SpringBoot知识点总结）

5.2 SpringBoot整合Junit
5.2.1 添加Junit的起步依赖

org.springframework.boot spring-boot-starter-test test 1 2 3 4 5 6 5.2.2 编写测试类 package com.itheima.test;

import com.itheima.MySpringBootApplication;
import com.itheima.domain.User;
import com.itheima.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;

import java.util.List;

@RunWith(SpringRunner.class)
@SpringBootTest(classes = MySpringBootApplication.class)
public class MapperTest {

@Autowired
private UserMapper userMapper;

@Test
public void test() {
    List<User> users = userMapper.queryUserList();
    System.out.println(users);
}

}
其中，

SpringRunner继承自SpringJUnit4ClassRunner，使用哪一个Spring提供的测试测试引擎都可以

public final class SpringRunner extends SpringJUnit4ClassRunner
