警告: Runner org.junit.internal.runners.ErrorReportingRunner (used on class com.boy.community.CommunityApplicationTests) does not support filtering and will therefore be run completely.

错误：

错误原因分析：@Test有两个包，一个是org.junit.jupiter.api.Test，另一个是org.junit.Test，而测试需要的Junit是org.junit.Test
解决方法：import org.junit.jupiter.api.Test换成import org.junit.Test;
