警告: Runner org.junit.internal.runners.ErrorReportingRunner (used on class cn.sdmmastest.util) does n

项目场景：

公司SpringBoot项目中，进行单元测试中

问题描述：

运行测试代码时，报错
警告: Runner org.junit.internal.runners.ErrorReportingRunner (used on class cn.midea.sdmmastest.util.connectUtilTest) does not support filtering and will therefore be run completely.
完整报错如下：

五月 11, 2021 11:14:45 上午 org.junit.vintage.engine.descriptor.RunnerTestDescriptor warnAboutUnfilterableRunner
警告: Runner org.junit.internal.runners.ErrorReportingRunner (used on class cn.midea.sdmmastest.util.connectUtilTest) does not support filtering and will therefore be run completely.java.lang.Exception: No runnable methodsat org.junit.runners.BlockJUnit4ClassRunner.validateInstanceMethods(BlockJUnit4ClassRunner.java:191)at org.junit.runners.BlockJUnit4ClassRunner.collectInitializationErrors(BlockJUnit4ClassRunner.java:128)at org.junit.runners.ParentRunner.validate(ParentRunner.java:416)at org.junit.runners.ParentRunner.(ParentRunner.java:84)at org.junit.runners.BlockJUnit4ClassRunner.(BlockJUnit4ClassRunner.java:65)at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.(SpringJUnit4ClassRunner.java:137)at org.springframework.test.context.junit4.SpringRunner.(SpringRunner.java:49)at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62)at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45)at java.lang.reflect.Constructor.newInstance(Constructor.java:423)at org.junit.internal.builders.AnnotatedBuilder.buildRunner(AnnotatedBuilder.java:104)

原因分析：

包导错了，在@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

解决方案：

将 import org.junit.jupiter.api.Test;替换为 import org.junit.Test;
