The Art of Testing Network Systems

This book addresses two technical domains that should be complimentary, but rarely are: (1) network and infrastructure maintenance and management, and (2) applications and systems QA.For the network infrastructure and maintenance domain this book provides a structured testing methodology that includes the key elements of both quality assurance and release of changes to production. For applications and systems testing teams it gives the necessary technical details for effectively performing applications and systems testing in a distributed environment. Too often the applications test group is called upon to conduct performance testing of distributed applications and miss some critical factors that should have been included in the test plan and associated test cases. The cause of this oversight is a lack of technical information in the application testing body of knowledge, which this book corrects.What makes this book especially valuable is the emphasis on availability, application response and reliability. These are essential elements of service level agreements and the author does not lose sight of that fact.I especially like the way the book starts by putting testing into a business and technical context. The eight chapters that comprise Part II of the book provide a structured test methodology that is completely consistent with testing best practices in the applications and systems test domain. This gives network and infrastructure professionals an effective and proven methodology, and gives their applications and systems colleagues a familiar point of reference because network testing has grey areas that overlap their domain.Part II will be familiar territory to network professionals and is in many ways the heart of this book. The test cases provided can be templated and used in real life QA efforts, adding value to this book. Part III is where the overlap between network and applications testing becomes apparent. The material provided in the chapters in this part are filled with invaluable information that will enable applications and systems test professionals to develop viable test plans and cases for "footprint" testing, performance and application response testing in distributed environments. This is where the book becomes valuable to both groups. Part IV, Test Tools, is obsolete and can be safely ignored. This is an outstanding book that should be in the libraries of both network maintenance and support groups and applications and systems QA groups. The approach provided is straightforward and is focused in the right direction - on availability and reliability in support of service levels.

The Art of Testing Network Systems provides the professional network tester blueprints for designing, implementing, and understanding the results of network testing. It is an easy to read useful reference. I would recommend it to network testers, test managers and end users charged with understanding test plans.
