Test case sample

package com.org.testng7;

import org.testng.annotations.Test;

public class Testng7{
	
	public Testng7() {
		// TODO Auto-generated constructor stub
	}

	@Test(groups = { "g1" }, priority = 1)
	public void t1() {
		System.out.println("Testng7:test 1" + " Thread ID: " + Thread.currentThread().getId());
	}

	@Test(groups = { "g2" }, dependsOnGroups = "g1", priority = 3)
	public void t2() {
		System.out.println("Testng7:test 2" + " Thread ID: " + Thread.currentThread().getId());
	}

	@Test(groups = { "g2" }, dependsOnGroups = "g1", priority = 2)
	public void t3() {
		System.out.println("Testng7:test 3" + " Thread ID: " + Thread.currentThread().getId());
