This book attempts to show the differences between (1) traditional mainframe development and its related testing, and (2) Client/Server rapid-development models and their testing concerns. The book provides many interesting insights into Client/Server and what aspects require testing. It is apparent that the author has a strong development background and is not as well founded in testing and QA concepts. There are many statements that reflect this skewed view of testing, but the book still has good information on testing in the Client/Server environment.
