SpringBoot单元测试：@SpringBootTest

添加依赖

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

编写测试类

package com.qzcsbj.demo;

import com.qzcsbj.demo.mapper.UserMapper;
import com.qzcsbj.demo.pojo.User;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import javax.annotation.Resource;
import java.util.List;

@RunWith(SpringRunner.class)  // 底层用的junit，public final class SpringRunner extends SpringJUnit4ClassRunner
@SpringBootTest(classes = SpringbootdemoApplication.class)
public class MyTest {
    @Resource
    UserMapper userMapper;

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

上面点击后，pom中自动加入了junit依赖

        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <scope>test</scope>
        </dependency>
