The complexity of software applications have increased due to the rapid evolution of web technologies. Certain web browsers are compatible with selective operating systems while certain browsers provide advanced privacy and automated features. Cross Browser Testing, or Browser Compatibility Testing, for an application needs to be performed across multiple cross browser platforms, operating systems and mobile devices to uncover discrepancies. To ensure the browser compatibility of an application, it is important to consider all the methods that end users utilize to interact with the application.

The main reasons for performing Cross-Browser testing can be summarized as follows:
