Product Description

From the Back Cover

Today's web software professionals must deliver new web applications to market quickly, while incorporating proper functionality, ease-of-use, security, and performance. This pressure underscores the need for effective engineering that facilitates both quality and rapid web system development.

Quality Web Systems provides web developers and software test professionals with practical, experience-based guidance on web system engineering. Concise and straightforward, this book provides a framework for ensuring that key web system success criteria is addressed during the development of the web system. Detailed, technical guidance is provided for each success criteria, including testing strategies that allow for verification of a quality implementation.

This book addresses the key success factors of quality web systems including: proper specification of system functionality, ease-of-use, compatibility with a variety of browsers, security, and system performance and scalability. Engineering these qualities into the system throughout the development life cycle, while performing relevant testing, prevents flaws that can later prove to be disastrous, and produces a product that is well-received by its customers.

A case study is used throughout the book to illustrate practical applications of issues, approaches, strategies, and techniques.

Specific topics covered include:

  • Web system success criteria
  • Engineering functionality through use case analysis
  • Test cases from RSI use cases
  • Security of web system components and databases
  • Compatibility with multiple web browsers
  • Performance and scalability behavior
  • Load analysis and capacity planning
  • Usability concerns and test strategies
  • Test tool evaluation guide

With the information and guidance in Quality Web Systems, you will be better able to ensure the development of a quality, timely, and successful web application.

Excellent book on various quality topics 19 Nov. 2001
By Jeff Nyman - Published on
Format: Paperback
This book was a joy to read. It gives a great overview of quality issues within "Web systems" - meaning Web applications and architectures. The book balances a too-specific look with a too-general look and succeeds quite well in a balanced treatment that will make the whole worth the attention of any quality assurance or quality tester professional in the Information Technology industry.
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.

Practical and relevant 31 Aug. 2001
By Ms. Mary R. Sweeney - Published on
Format: Paperback
Quality Web Systems is another thorough and complete book by the same team who wrote Automated Software Testing. I am finding the same quality and insight in this book. Web Systems testing is THE critical testing area in software quality assurance today. I appreciate the thoughtful and practical approach this text takes. I found the sections on Usability Test Strategies and the test tool evaluation guide particularly relevant to my situation. I think this is a book every tester should have. I highly recommend it.

Covers all of the major issues and factors 23 Sept. 2001
By Mike Tarrani - Published on
Format: Paperback Verified Purchase
Although the authors of this book are noted experts in software testing this book goes far beyond testing by addressing the full range of quality and design issues for web-based systems.
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.

Once again another blockbuster! 25 Sept. 2001
By Amjad Alhait - Published on
Format: Paperback
This is one of the best quality assurance books in a while... Thinner than Automated Software Testing, but as informative! If you are doing any kind of web testing, this one's a must have for your library. Talks about all aspects of software testing on the web. I give it 5 stars hands down!

Ancient and Outdated 26 Jan. 2011
By Tomas A. Maly - Published on
Format: Paperback Verified Purchase
I recently purchased this book hoping to learn something useful about developing high performance and usable web systems, but it read more like a technical manual from the 1990's. I saw all 5 star reviews but didn't think that any web book dated pre-2005, wait 2006, wait 2007, wait 2008, is probably useless. Next time I'll know better to look at the publish date, and the dates of the reviews. I can't believe how infantile the Internet was just 10 years ago. The moment I saw Jakob Nielsen endorse the book in the forward, I knew it was going to be useless. Luckily I only paid $4.57 for the book. Maybe I can walk away with one useful tip.

Even if it were 2002, I doubt there's anything "Quality" about anything the book covers. Seems like re-hashing a bunch of common sense stuff anyone who is in development would know.
