"Effective Software Testing explores fifty critically important best practices, pitfalls, and solutions. Gleaned from the author's extensive practical experience, these concrete items will enable quality assurance professionals and test managers to immediately enhance their understanding and skills, avoid costly mistakes, and implement a state-of-the-art testing program. This book places special emphasis on the integration of testing into all phases of the software development life cycle--from requirements definition to design and final coding. The fifty lessons provided here focus on the key aspects of software testing: test planning, design, documentation, execution, managing the testing team, unit testing, automated testing, nonfunctional testing, and more. You will learn to: Base testing efforts on a prioritized feature scheduleEstimate test preparation and executionDefine the testing team roles and responsibilitiesDesign test procedures as soon as requirements are availableDerive effective test cases from requirementsAvoid constraints and detailed data elements in test proceduresMake unit-test execution part of the build processUse logging to increase system testabilityTest automated test tools on an application prototypeAutomate regression tests whenever possibleAvoid sole reliance on capture/playbackConduct performance testing with production-sized databasesTailor usability tests to the intended audienceIsolate the test environment from the development environmentImplement a defect tracking life cycle Throughout the book, numerous real-world case studies and concrete examples illustrate the successful application of these important principles and techniques. "EffectiveSoftware Testing provides ready access to the expertise and advice of one of the world's foremost software quality and testing authorities.
