Though the book bears my name, it truly reflects the collective wisdom of the numerous customers of Mercury Interactive (now taken over by HP) with whom I interacted as a CSO support engineer to resolve their queries related to WinRunner and QTP, and my colleagues with whom I worked. I have learned a lot from them. My many thanks to all of them!

Many thanks to Dinesh and Selvaraj for providing me with valuable inputs to make this book better.

Authors need a lot of support from their publishers. I thank Akash and Deepika for their patience and tolerance towards the mistakes I committed while writing the contents of the book. Salute to Kevin for having faith in my idea of this book.

Lastly, thanks to my parents, and my wife Neeti, who cheered me in good times and encouraged me in bad times.
