Setup and Trigger test automation using testng through code

This post shows how we could use testng class,generating html report ,setting test classes through the code.

Please download following jars :
1. http://reportng.uncommons.org/ 
2. http://testng.org/doc/download.html

Following is the Java Code:

 public static void main()
{
    Testng tng=new TestNg();
    LinkedList<Class> ll=new LinkedList<Class>();
    ll.add(HTMLReporter.class);

   tng.setTestListenerClasses(ll);
   tng.setOutputDirectory("d:\\test");
   tng.setTestClasses(new Class[]{Test.class});
   tng.run();
}

Following is the sample test class :

class Test
{
 
  @Test
   public void fun() // this methods will pass
  {
    System.out.println("fun");
    Reporter.log("This is passed");  
  }

  @Test
   public void fun2() //this method will fail.
  {
    System.out.println("fun2");
    Reporter.log("This is failed");  
    throw new Error();

  }


  
}
