Same test with different data’s

TestNG Parametric (TestNG Parameter) test lets you to pass the same test with different options. Hence you can easily pass different data’s in a same test.

How it is done?

TestNG Parameter has two different types of methods to does that,

  •  With testing.xml
  • With Data Providers

Using testing.xml to pass parameters

 In this process the

  • first step is to define the simple parameters in the testing.xml file.
  • Once it is define then make a reference of those file with the source file.

How to do it…

Below simple login example will describe about clearing the authentication for both Username and Password.

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.firefox.FirefoxDriver;

import org.testng.annotations.Test;

import org.testng.annotations.Parameters;

public class TestngParameters {

private static WebDriver driver;


@Parameters({ “sUsername”, “sPassword” })

public void test(String sUsername, String sPassword) {

driver = new FirefoxDriver();

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);










Here the parameter passing happens using testNG.XML

<suite name=”Suite”>

<test name=”ToolsQA”>

<parameter name=”sUsername” value=”testuser_1″/>

<parameter name=”sPassword” value=”Test@123″/>


<class name=”automationFramework.TestngParameters” />




So now while running TestNG parameter will find the parameter named username and password.
