springboot中使用junit编写单元测试，并且测试结果不影响数据库。

pom引入依赖

如果是IDE生成的项目，该包已经默认引入。

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

数据库原始数据

原始数据

编写单元测试

package com.mos.quote;import com.mos.quote.model.Area;import com.mos.quote.service.IAreaService;import org.junit.Assert;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.annotation.Rollback;import org.springframework.test.context.junit4.SpringRunner;import org.springframework.transaction.annotation.Transactional;import java.util.List;@RunWith(SpringRunner.class)@SpringBootTestpublic class QuoteApplicationTests {  @Autowired  private IAreaService areaService;  @Test  public void contextLoads() {  }  @Test  public void testUpdate(){    Area area = new Area();    area.setCode("001003");    area.setName("洛阳市");    Integer result = areaService.update(area);    Assert.assertEquals(1, (long)result);  }  @Test  @Transactional  @Rollback  public void testUpdate4Rollback(){    Area area = new Area();    area.setCode("001001");    area.setName("郑州市123");    Integer result = areaService.update(area);    Assert.assertEquals(1, (long)result);  }}

结果数据
