It might happen that you always use the same browser when working on your website. When it comes to browsers, Chrome is one of the most popular browsers among internet users due to its largest market share. However, Firefox, Safari, and Microsoft Edge are still popular alternatives.
Although most have similar functionality, they're coded differently and have different features. Therefore, one website may not look or act the same across all browsers. If you only viewed the website on Chrome and switched to Firefox or Safari, you can see the variances in the look and feel of the website. So, different browsers can have different perspectives.
There can be a difference in how components are rendered across different environments. Therefore, it's crucial to test websites across different browsers, devices, and operating systems, also known as cross browser testing.
Before launching your website publically, you must ensure that it renders correctly on different browsers, browser versions, devices, and operating systems. The purpose of cross browser testing is to identify cross browser compatibility issues of your websites and web apps to enhance the user experience. It helps debug the issues more quickly and ensures that you don't compromise on user experience.
