本文详细解析了SpringBoot单元测试启动时报错的原因，主要是由于test中的包名与main中包名不一致导致。提供了两种解决方案：一是将test中的包路径修改为主程序路径；二是将启动类移至与测试类相同的目录。

Process finished with exit code -1

报错原因：
在进行单元测试时，test中的包名与main中包名分支不一致导致。
如图：
错误信息
解决方案：
将test中的分支改为与main中的分支一样的路径。就可以了！
或者是将我们springboot的启动类移到与test测试类一样的目录下也可以的！
如图：
在这里插入图片描述
然后再执行就没有问题啦~
