Cross Browser Compatibility Testing Checklist
Apart from the intended and appropriate working of a web application, its compatibility and functioning across multiple browsers is a significant factor that needs to be considered while developing the web applications.
Cross browser testing is a unique testing technique, developed in the direction of testing the compatibility of a web application on multiple variants of browsers.
