What Is Cross-Browser Compatibility Testing?

We have read various definitions of cross-browser testing over the internet, which clearly states that verifying the functionality of a web app across multiple browsers is known as cross-browser testing. It ensures that the website will provide the same experience to every user on different browsers and operating systems.

Earlier, cross-browser testing was carried out manually by a team of developers and testers by creating and executing test scripts for each browser individually, which used to be very time-consuming as well as costly because it requires multiple systems with various operating systems and browsers. Also, it was not possible to test all the browsers with manual testing.

With innovations in technology, businesses started automating the cross-browser testing of their web apps. Though automation was already incorporated in various organizations for cross-browser testing with the help of Selenium, it was not up to mark. Now, there are multiple cross-browser testing tools available in the market that make it much easier for testers to automate the cross-browser testing of web apps. But, choosing the best cross-browser testing tool is still a daunting task for many companies.

Here, we have enlisted the best automated cross-browser testing tools that can help you improve your browser testing in 2020.

Checklist For Using An Automation Testing Tool

Before selecting an automated cross-browser testing tool, it would be great to analyze which browsers you need to test on. If you have a history of visitors on your site, you can use that data to check the browsers that are mostly used to access your website.

Another great way to choose browsers is to examine the usage share of browsers provided by Wikipedia. After shortlisting the browsers that you want to test, you can select an automation tool for testing.

While executing cross-browser testing of your website, make sure you cover the following sections:

  • HTML and CSS Validation.
  • Page validations with or without JavaScript.
  • Page styles and date formats.
  • Page layout in different resolutions.
  • Ajax and jQuery functionality.
