Testing Challenges in Web Applications This thesis research focuses specifically on testing challenges of Web-based application with respect to interoperability and integration; further research in this domain can be more beneficial for both academia and industry. Industrial survey shows that most of the companies are doing integration and interoperability testing manually. Though automated testing tools are very beneficial and helpful to speed-up the testing process but these are not being used to perform both integration and interoperability testing. Therefore this book is beneficial for the researchers and students who further wants the research in this area.
