TestNG Parameters

As we all know the value of Parameterization in automation testing. It allows us to automatically run a test case multiple times with various inputs and validation values. while creating a automation framework we need to put in some effort to support data driven testing in our automated tests. In this video we will see how we can parameterize a test case using TestNG parameters.

TestNG provides us interesting feature called TestNG Parameters. TestNG lets you pass parameters directly to your test methods with your testng.xml.

How to do it?

Let me take a very simple example of Search on our site www.qaautomated.com, where the search text  is required to perform authentication.

1) Create a test case to perform Search which takes the one string argument as searchtext.

2) Provide searchtext as parameter using TestNG Annotation.

package test;


import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.Test;
import org.testng.annotations.Parameters;
 
public class TestNGParameters{
 
 private static WebDriver driver;
 
  @Parameters("searchtext")
  @Test  
  public void test(String searchtext) throws InterruptedException {
 
   System.setProperty("webdriver.chrome.driver", "C:\\Softwares\\chromedriver_win32\\chromedriver.exe");
  
   driver=new ChromeDriver();
      
      driver.get("http://www.qaautomated.com");
 
      Thread.sleep(5000);
      driver.findElement(By.xpath("*//input[@class='search-field']")).sendKeys(searchtext);
      
      driver.findElement(By.xpath("*//input[@class='search-submit']")).click();
 
      driver.quit();
 
  }
 
}

3) Provide Search text value in testng.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite">
  <test thread-count="5" name="Test">
   <parameter name="searchtext" value="appium"/>
    <classes>
      <class name="test.TestNGParameters"/>
    </classes>
  </test> <!-- Test -->
</suite> <!-- Suite -->

4) Right click on testng.xml and run as TestNG Suit
