    Similar to SUREFIRE-346 but for JUnit4, Surefire tries to run classes that contain no @Test annotations as tests, resulting in the exception: java.lang.Exception: No runnable methods at org.junit.internal.runners.MethodValidator.validateInstanceMethods(MethodValidator.java:32) at org.junit.internal.runners.MethodValidator.validateMethodsForDefaultRunner(MethodValidator.java:43) at org.junit.internal.runners.JUnit4ClassRunner.validate(JUnit4ClassRunner.java:36) at org.junit.internal.runners.JUnit4ClassRunner.<init>(JUnit4ClassRunner.java:27) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:494) at org.junit.internal.requests.ClassRequest.buildRunner(ClassRequest.java:33) at org.junit.internal.requests.ClassRequest.getRunner(ClassRequest.java:28) at org.apache.maven.surefire.junit4.JUnit4TestSet.<init>(JUnit4TestSet.java:45) at org.apache.maven.surefire.junit4.JUnit4DirectoryTestSuite.createTestSet(JUnit4DirectoryTestSuite.java:56) at org.apache.maven.surefire.suite.AbstractDirectoryTestSuite.locateTestSets(AbstractDirectoryTestSuite.java:96) at org.apache.maven.surefire.Surefire.createSuiteFromDefinition(Surefire.java:209) at org.apache.maven.surefire.Surefire.run(Surefire.java:156) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.apache.maven.surefire.booter.SurefireBooter.runSuitesInProcess(SurefireBooter.java:338) at org.apache.maven.surefire.booter.SurefireBooter.main(SurefireBooter.java:997) Such classes should be ignored by Surefire.
