What Is Cross-Browser Testing?

In order to ensure that websites and web applications run consistently and render appropriately across a variety of web browsers and their iterations, cross-browser testing is an essential step in the web development process. Cross-browser testing assists in identifying and resolving potential compatibility problems because different browsers interpret and render code in different ways. It entails looking at how the website functions, is structured and appears in various browsers, such as Chrome, Firefox, Safari, Internet Explorer, and Edge.

Cross-browser testing allows developers to ensure that their online projects display and function as intended across all end-user browsers. It encourages accessibility, guards against obtrusive and unappealing design flaws, and ensures a smooth user experience.
