All of the major elements of web-engineering and quality are addressed, including SECURITY (this is the first test or quality book that fully acknowledges the relationship between quality and security, which is a cornerstone of the Reliability-Availability-Support triad for systems in production), PERFORMANCE (I especially liked this section because it got into the guts of performance and scalability), COMPATIBILITY (essential for ensuring that your system works with the world of users over whom you have no control - web-based systems can and usually do extend into the great unknown), and USABILITY (this will make or break a commercial web site).
Aside for the complete coverage of all of the important topics that need to be considered, and the life cycle approach to quality and testing this book contained a real gem: RSI approach to use cases. RSI (Requirements-Service-Interface) is an interesting and highly useful approach to use cases. Some key strengths of using the RSI paradigm is that you will ensure traceability between requirements and the services and interfaces that are implemented. Moreover, this approach partitions services and interfaces, which allows you to manage the complexities when developing a test strategy and associated test cases. To me the chapter on RSI was worth the price of the book.
Overall, this is a solid book that covers testing, as well as the larger domain of systems quality. It gives some unique insights of issues and factors related to testing, but is not solely about web testing. It should be read by all key team members including requirements analysts, architects, developers, test engineers and project managers *before* a web project is initiated.
In particular, the second chapter, on the RSI Approach, is a nice addition as this is something that most practitioners of quality subjects will not find elsewhere and the general subject matter is generally that which is avoided in books of this type. Another topic often avoided in these books is that of usability and accessibility concerns and yet these are covered here in good detail chapter six.
In general, I think the book offered a great amount of detail just where it was needed and gave a lot of "mini best-practices" in each chapter with the use of bulleted lists to highlight specific points. The detail of the book extends to various topics, like performance, compatibility, usability, and security - all topics that are of high concern in the current world of making qualitly Web systems that customers and user respond to. The appendices in the book are also excellent. The "Test Tool Evaluations" section will be a welcome addition to those who wish there are more concise evaluation forms for automated tool solutions.
I highly recommend this book to quality assurance/testing professionals, quality assurance managers, and even those who work more in the project management and development spheres. Those latter will get benefit from the book because the book manages to highlight topics of concern to both groups and also gives them insight into the quality aspects of the projects and products that are developed within an organization.
