Website Testing is both an art and the craft of validating software. Web software testing is an umbrella activity i.e. it must be done throughout SDLC. But another term "quality" is also being emphasized today. The need is to have a combined book on web software testing and quality assurance. Better testing means more security. More security means lesser hacking. Thus, both testing and security go hand in hand. They are interrelated. This book is an attempt to all such queries of testing.
