Cross-browser testing is a type of non-functional software testing where web applications are checked for support across different browsers and devices. Cross-browser testing can also provide an objective, independent view of the status of the web application to allow the business to appreciate and understand the risks of releasing it or implementing new feature(s). Test techniques include the process of executing a web application with the intent of finding failures in different browsers and devices and verifying that the website is fit for use in all of them. In other words, Cross-browser testing is verification that web application behaves in various web browsers identically
