4. Writing the first test case using Selenium and TestNG

Let’s start by writing our first test case using Selenium and TestNG. Below is a sample code for a test case to open a web page using ChromeDriver:

package com.example.tests;

import org.openqa.selenium.WebDriver;


import org.testng.annotations.Test;

public class FirstTest {


public void testGoogleSearch() {

// Set the path of the ChromeDriver executable

System.setProperty(“”, “path/to/chromedriver.exe”);

// Launch Chrome browser

WebDriver driver = new ChromeDriver();

// Navigate to Google


// Verify the title of the page

if(driver.getTitle().equals(“Google”)) {

System.out.println(“Test Passed!”);

} else {

System.out.println(“Test Failed”);


// Close the browser




This test case uses the ChromeDriver to launch the Chrome browser, navigates to Google, verifies page’s title, and closes the browser. The ‘@Test’ annotation is used to indicate that this is a TestNG test case.

You can modify this code to suit your specific testing needs.

5. Run your Selenium TestNG Script

To run your Selenium TestNG script, you can follow these simple steps:

  1. Go to your test script and right-click on it.
  2. From the menu, select “Run As” and then “TestNG Test”.
  3. Your script will now be executed, and you can monitor the progress in the console.
  4. Once the script has completed running, you can view the test results either in the TestNG reports or in the console itself.
  5. If there are any errors or failures in your test script, TestNG will highlight them in the results, allowing you to identify and fix the issues easily.

By following these steps, you can easily run your Selenium TestNG script and get valuable insights into the performance and functionality of your web application.

Upgrade Your Selenium Game with LambdaTest – The Ultimate Cloud Selenium Grid!


Hey there, it looks like you’re doing great with your Selenium TestNG scripts, but let’s take things up a notch! Imagine you’re the Iron Man of Selenium testing, trying to save the world from slow and inefficient test runs.

So, you’ve got your Selenium WebDriver on your local machine, but what if you need to run your tests on multiple browsers and operating systems? That’s where a Selenium Grid comes in, and let’s be honest, running tests in parallel is way cooler than doing them one at a time. It’s like assembling the Avengers and taking on the bad guys all at once!

But hold on a second, building and maintaining your own Selenium Grid can be a hassle, like trying to build your own suit of armor in a cave. That’s why you should consider using a cloud-based Selenium Grid, like LambdaTest. Think of it as your own Jarvis, always there to help you out with your testing needs.

With LambdaTest, you can run your Selenium TestNG scripts on over 3000 real browsers and operating systems, so you won’t have to worry about which ones are new in the market. Plus, you can save the money you would have spent on building and maintaining your in-house Selenium infrastructure and spend it on something more exciting, like a trip to Asgard.

Here’s an example test case using Selenium and TestNG that can be run on the LambdaTest platform:

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.remote.DesiredCapabilities;

import org.openqa.selenium.remote.RemoteWebDriver;

import org.testng.Assert;

import org.testng.annotations.AfterMethod;

import org.testng.annotations.BeforeMethod;

import org.testng.annotations.Test;



public class LambdaTestExample {

public WebDriver driver;

public String username = “YOUR_USERNAME”;

public String accessKey = “YOUR_ACCESS_KEY”;

public String gridURL = “”;


public void setUp() throws MalformedURLException {

DesiredCapabilities capabilities = new DesiredCapabilities();

capabilities.setCapability(“browserName”, “Chrome”);

capabilities.setCapability(“version”, “91.0”);

capabilities.setCapability(“platform”, “WIN10”);

capabilities.setCapability(“build”, “LambdaTestSampleApp”);

capabilities.setCapability(“name”, “LambdaTestJavaSample”);

capabilities.setCapability(“network”, true);

capabilities.setCapability(“visual”, true);

capabilities.setCapability(“video”, true);

capabilities.setCapability(“console”, true);


capabilities.setCapability(“timezone”, “UTC+05:30”);

// Launch remote browser and set it as the current thread

driver = new RemoteWebDriver(new URL(“https://” + username + “:” + accessKey + gridURL), capabilities);



public void lambdatestExampleTest() {

// Navigate to LambdaTest homepage


// Verify title of the page

String pageTitle = driver.getTitle();

Assert.assertEquals(pageTitle, “Cross Browser Testing Tool | Browser Compatibility Testing – LambdaTest”);

// Assert that there is a CTA button on the page

boolean ctaButtonExists = driver.getPageSource().contains(“Start Free Trial”);




public void tearDown() {

// Close the browser




To run this test case on the LambdaTest platform, you will need to replace “YOUR_USERNAME” and “YOUR_ACCESS_KEY” with your actual LambdaTest username and access key, respectively. You will also need to update the DesiredCapabilities object to specify the desired browser, version, and platform you want to run the test.

Lamba test

Once you’ve made those changes, you can upload the test case to the LambdaTest platform and run it on any of the 3000+ browser/OS combinations available.

Happy testing!
