I have been doing SQA and related engineering for almost twenty years and have not seen many books that actually get into the "nuts and bolts" of software testing as well as this one does. Mosley takes great pains to insure that whether you are a newcomer to SQA or a seasoned pro, something is here for you. I recently moved from a strictly software testing environment to a Client-Server environment and used this book extensively to "get up to speed" with the new internet testing concepts presented in this publication. Very practical examples, clear explanations and a thorough knowledge of the topic. I would highly recommend this book to anyone who is new to the field and any one needs ideas on how to put a test environment together that really produces immediate results. I have worked on many software engineering projects over the past twenty years and wished many times for a book like this, now its here.
Of all the sofware testing books I've read, Mosley's stands out as the easiest to read, and contains real-world tangible examples that can be put to use immediatley. His Test Plan outlines are excellent and are built from IEEE standards. Lots of useful information and minimum test philosophy. Like many client-server books, the focus is primarily e-commerce, but the test approaches can be applied to any multi-user GUI application.
