我的应用程序在main和test resources文件夹中有application.yml，但是应用程序（spring boot 2.4 with maven）抱怨找不到application.properties。
下面是错误。

2021-07-08 04:37:33.381 ERROR   --- [           main] o.s.test.context.TestContextManager      : Caught exception while allowing TestExecutionListener [org.springframework.test.context.support.DependencyInjectionTestExecutionListener@bd4ee01] to prepare test instance [com.test.SomeTests@6a7aa675]

我试图在网上找到解决方案，但找不到。请帮忙。
