聊聊springboot2.2.3升级到2.4.0单元测试的区别

这篇文章主要介绍了springboot 2.2.3 升级到 2.4.0单元测试的区别，具有很好的参考价值，希望对大家有所帮助。如有错误或未考虑完全的地方，望不吝赐教

springboot2.2.3升级到2.4.0单元测试区别

原先单元测试 import org.junit.Test; 然后运行正常，现在运行报错，

				?

									import org.junit.Test;

换成

				?

									import org.junit.jupiter.api.Test;

后运行正常。

单个单元测试的这样没有问题了，但是我批量执行的还是会报上面的错误

				?

									@Suite.SuiteClasses({

									        //dao层测试类

									        //service层测试类

									        CheckConfigServiceTest.class,

									        AfterCheckConfigServiceTest.class,

									        //control层测试类

									        //WebTestControllerTest.class       

									        //util测试类       

									    })

									@RunWith(Suite.class)  

									public class BatchTest {

									}

最后确实没有解决整合测试也称打包测试的@Suite.SuiteClasses方法，不过找到了别的批量执行单元测试的方法，

在src/test/java 文件夹右键，run as -> junit test 一样可以批量执行！！！

springboot2.4降级到boot2.2.x

最近在做一个springcloud的整合项目，但是springcloud-alibaba的nacos只支持2.2.x版本，而项目开始也没注意，直接用的2.4版本，所以这里记录下降级踩下的坑。

这里直接把boot版本号改成2.2.6然后去启动主启动类会出现

				?

									<parent>

									    <groupId>org.springframework.boot</groupId>

									    <artifactId>spring-boot-starter-parent</artifactId>

									    <version>2.2.6.RELEASE</version>

									    <relativePath/> <!-- lookup parent from repository -->

									</parent>

以下提示：我的spring和我的boot不兼容，我boot版本太低，让我改成2.3或者是2.4
