java.lang.Exception：运行 JUnit 时没有可运行方法异常

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，我正在使用以下命令运行 JUnit :

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

测试单元类：

 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);
   }
}

测试运行器：

 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());
   }
}

我在运行时收到以下异常

Answer 1

如果您使用 JUnit 4.4 核心 运行程序执行没有 "@Test" method 的类，您将得到此异常。 请查阅链接以获取更多信息。

Answer 2

就我而言，我导入了错误的包：

 import org.testng.annotations.Test;

代替

import org.junit.Test;

当心你的 ide 自动完成。
