Hassle in a startup is not a new thing. Most startups struggle to grow. They try everything and make sure to deliver the best things on time, however, some things are underrated or are confused to be of less importance. Cross-browser testing in a startup is one such thing.
Cross-browser testing is testing your website or web application in different browsers or browser versions or devices and operating systems to make sure that the web app or website works perfectly in all of them.
