安装完testNG后，创建第一个程序hello，导入testng的jar包，新建hello类，如下：

> package com.shanghai.test;> > public class Hello {> >   public String mail() {      return "32423@qq.com";  } }

新建testng类TestHello测试hello类，代码如下

package com.shanghai.test;import org.testng.Assert;import org.testng.annotations.Test;public class TestHello {  @Test  public void f() {      Hello he = new Hello();      String aa = he.mail();      Assert.assertNotNull(aa);      Assert.assertEquals(aa, "32423@qq.com");  }}

执行testng程序，报如下错误：

原因：没有添加jcommander jar包
maven下载jcommander-1.48.jar包Builder path后执行成功
