Testing of Web Applications
WebApp testing is a collection of related activities with a single goal: to uncover errors in WebApp content, function, usability, navigability, performance, capacity, and security. To accomplish this, a testing strategy that encompasses both reviews and executable testing is applied throughout the Web engineering process. The following topic categories are considered here:

General Testing Resources

Testing/QA Articles and Papers

Navigation and Configuration Testing
