springboot bug记录 ：单元测试 Unable to find a @SpringBootConfiguration

背景：

springboot module工程，单元测试，遇到如下报错，移动测试文件位置后，得到解决。
具体过程如下：

报错：

java.lang.IllegalStateException: 
Unable to find a @SpringBootConfiguration,
you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test

原因：

是将测试类文件，生成到springboot module 中的非启动的、没有配置文件的module模块中，造成了报错；

解决：

将生成的测试文件，移动到springboot的启动module中。

移动位置后，执行单元测试成功

扩展：

springboot 单元测试的小提示：

类名或者方法名上，Generate - Test 可以生成对应的单元测试方法名

选择需要单元测试的方法名，之后选择位置，就可以生成单元测试的框架空文档了；

编外：

忽略：

附带一下完整的报错记录
