在Eclipse中使用maven以编程方式运行testNG而不使用插件

Question

我希望在一个普通的maven quickstart项目中运行TestNG，而不使用“TestNG eclipse插件”。

无论我从http://testng.org/doc/documentation-main.html#running-testng-programmily和其他来源中读到什么，我都知道如何使用类：

messageUtil.java

package com.mytests.testng;

public class MessageUtil {
   private String message;

   public MessageUtil(String message){
      this.message = message;
   }

   public String printMessage(){
      System.out.println(message);
      return message;
   }   
}

testngexample.java

package com.mytests.testng;

import org.testng.Assert;
import org.testng.annotations.Test;

public class TestNGExample {
   String message = "Hello World";  
   MessageUtil messageUtil = new MessageUtil(message);

   @Test
   public void testPrintMessage() {   
      Assert.assertEquals(message,messageUtil.printMessage());
   }
}

app.java

package com.mytests.testng;

import org.testng.TestListenerAdapter;
import org.testng.TestNG;

public class App
{
    public static void main( String[] args )
    {
        System.out.println( "Hello World!" );
        TestListenerAdapter tla = new TestListenerAdapter();
        TestNG testNG = new TestNG();

        @SuppressWarnings("rawtypes")
        Class[] testClasses = new Class[]{
                TestNGExample.class
        };

        testNG.setTestClasses(testClasses);
        testNG.addListener(tla);
        testNG.run();
    }
}

但这里我有例外：

出现此问题是因为在运行时，testng jar在类路径中不可用。您可以通过在testng pom依赖项中使用 compile 而不是 test 来解决这个问题。
