java ubuntu-12.04 junit junit4

2022-08-31 09:39:28

我正在尝试在我的Linux命令提示符上运行JUnit，其中包含必要的JARS（hamcrest-core-1.3.jar和junit.jar）和类文件，我正在使用以下命令来运行JUnit：/opt/junit/

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

TestJunit class：

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);
   }
}

测试跑者：

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());
   }
}

我在运行此程序时遇到以下异常

如果您使用 JUnit 4.4 核心运行器执行没有 .有关详细信息，请参阅链接。"@Test" method

答案 2

在我的情况下，我导入了错误的包：

import org.testng.annotations.Test;

而不是

import org.junit.Test;
