With the rapid advancements in technology and digitization, businesses strive to get the best out of it and ensure their web app runs smoothly on all browsers and platforms. In today’s scenario, businesses rely on Internet presence to increase their ROI and expand their online reach. This is the reason why most web applications are designed to be compatible with multiple browsers. It is very crucial to any responsive web application as one has to ensure that the application is compatible with every browser and browser version at any given time. Nonetheless, cross browser testing is something that has been overlooked, as there are many challenges of cross browser testing that developers face while incorporating it into the QA workflow. With the customer’s attention span getting shorter with time, they won’t hesitate to press the back button on their browser if a site seems faulty. So, what’s the solution?
