If you have a website for consumer products, you must know that some challenges exist only with these websites; one such challenge is ensuring that the functionalities work expectedly across browsers and devices. Browsers interpret things differently; hence you have to ensure consistency in the appearance (UI/UX) and functionalities of the website/web application across different browsers.
This makes cross-browser testing extremely important as it lets you compare the functionalities and design of a website on multiple browsers, devices, and platforms (operating systems). To fast-track the process of browser compatibility testing, developers should use automated browser testing.
