java.lang.Exception : No runnable methods exception in running JUnits

Question

我正在尝试在我的 Linux 命令提示符下运行 JUnit /opt/junit/ 包含必要的 JARS(hamcrest-core-1.3.jar 和 junit.jar)和类文件，我是使用以下命令运行 JUnit:

java -cp hamcrest-core-1.3.jar:junit.jar:. org.junit.runner.JUnitCore  TestRunner

TestJunit 类:

import org.junit.Test;
import static org.junit.Assert.assertEquals;
public class TestJunit {
   @Test
   public void testAdd() {
      String str= "Junit is working fine";
      assertEquals("Junit is working fine",str);
   }
}

TestRunner:

import org.junit.runner.JUnitCore;
import org.junit.runner.Result;
import org.junit.runner.notification.Failure;

public class TestRunner {
   public static void main(String[] args) {
      Result result = JUnitCore.runClasses(TestJunit.class);
      for (Failure failure : result.getFailures()) {
         System.out.println("fail ho gaya"+failure.toString());
      }
      System.out.println("passed:"+result.wasSuccessful());
   }
}  

我在运行时遇到以下异常

如果您使用 JUnit 4.4 核心运行程序 执行没有 "@Test"方法的类，您将收到此异常。 Kindly consult the link for more info.
