Executing Selenium Tests on Different Browsers with LambdaTest

Executing Selenium Tests

Advanced website testing is essential for building a website packed with advanced features. Testing web applications is the only method to be sure that the website or web app is functioning and performing as planned. It identifies significant problems with the website, such as compatibility problems, device configuration problems, performance bottlenecks, etc.  Therefore, it’s crucial to test the web application for compatibility to ensure that users have a seamless experience while visiting the website.

Cross browser testing, commonly referred to as browser compatibility testing, is essential in determining if websites and web applications are compatible with all relevant browsers, operating systems, and hardware.

Cross-browser testing is a laborious, complex, and time-consuming task with all the rich functionalities of a web application across various browsers, devices, and operating systems. However, with the advent of test automation, teams now find it much simpler to work on repetitive and advanced testing processes.

In addition, advanced web testing automation tools like Selenium offer a strong framework for implementing tests across the range of operating systems and browsers on the market as well as with various kinds of data to increase test coverage.

We will learn how to use LambdaTest to run Selenium tests on several browsers in this article. Before we dive deeper into the subject, let’s quickly review what Selenium automation and cross-browser testing are and explain why LambdaTest is used for this purpose.

Selenium automation testing

Cross-browser testing can be efficiently automated with the help of the open-source Selenium testing framework. It can verify the compatibility of websites and web apps with various operating systems and browser settings. No matter what operating system or browser they are using, this guarantees that every user has the same experience. With the help of Selenium, developers can create test scripts using a single interface and a language such as C#, Python, Node.js, or Java.

Selenium is the most well-known automated testing framework and offers reliability and safety. The fact that there are no licensing fees associated with using Selenium is its greatest benefit.

Cross Browser Testing

The technique of evaluating a website or app across many browsers is known as cross-browser testing. This testing is done to make sure that the website or app renders flawlessly in a variety of browsers and operating systems without losing its quality. This will make it easier to see where it falls short and what has to be done to make it better so that more users, regardless of their device, operating system, or resolution, can access and use it.

Image orientation, user input location and validation, font size, and page alignment are just a few of the variations found between browsers. In addition, some operating systems are incompatible with specific browsers. Cross-browser testing enables testers to identify and fix these problems, enhancing the user experience.

As we’ve already mentioned, starting cross-browser testing manually may be expensive and extremely time-consuming, especially given the numerous browser, operating systems, and device combinations that need to be tested. These tests can be run simultaneously and much more quickly if they are automated using Selenium.

Additionally, it eliminates any problems caused by human error. Selenium is a suitable option for cross-browser testing since it is a suite of three components, including the IDE, WebDriver, and Selenium Grid, rather than a single tool. Here, we’ll execute tests concurrently using Selenium Grid.

What is a Selenium Grid?

One crucial client-server-based technology in the Selenium suite is called Selenium Grid. Users using Selenium Grid can simultaneously run tests on various computers using various browsers and browser versions. This makes testing easier and helps test suites scale as they grow.

The Selenium grid is organized in a Hub and Node style. In a selenium grid, the client computer is known as the “Hub,” while the server or servers are known as the “Nodes.” By running the tests simultaneously on several machines, a selenium grid greatly aids in speeding up time-consuming and extensive test suites.

However, the key difficulty here is setting up and maintaining local infrastructure for Selenium Grid on the local system to carry out cross-browser testing across several browsers, operating systems, and devices. Because it takes time and requires extensive Selenium knowledge to set up a Selenium grid on the system or to create the infrastructure for one.

A better alternative to setting up Selenium Grid on a local system is to use Online Selenium Grid, which can solve all cross-browser testing issues and doesn’t need any kind of setup to run tests on different machines.

LambdaTest is one such AI-powered test orchestration and execution platform that offers an online Selenium Grid that simplifies the complete testing process by offering all browsers and operating systems in the cloud. There is no need to download or install browsers on the local system as a result. Testers may quickly and effectively test for manual and automated cross-browser compatibility in the browser on the cloud using Lambda Tests Selenium grid.

From a quick introduction to Selenium, Selenium Grid, and browser testing Let’s move on to how LambdaTest’s online Selenium grid facilitates the execution of Selenium tests across several browsers.

Why use LambdaTest to test on different browsers?

Currently, just a few popular browsers, including Chrome, Firefox, Internet Explorer, and Safari, account for the majority of browser usage. But in addition to that, there are a wide variety of alternative browsers on the market for different platforms, including Android, Mac, iOS, and Windows, as well as desktop, mobile, and tablet devices. Any browser, any operating system, and any device can be used to visit the website.

Therefore, testing for cross-browser compatibility must be done across almost all platforms, operating systems, and browsers. LambdaTest is an AI-powered test orchestration and execution platform that offers an online Selenium Grid that enables users to conduct automated testing for publically or locally hosted web apps using a combination of more than 3000 real devices, browsers, and operating systems with their corresponding versions.

The ability to test your web app manually and automatically is one of the best things about LambdaTest.
