Web Application - Interface and Compatibility Checklist

Testing web application is certainly different than testing desktop or any other application. With in web applications, there are certain standards which are followed in almost all the applications. Having these standards makes life easier for use, because these standards can be converted into checklist and application can be tested easily against the checklist.
