Inhaltsangabe

Software in medical devices, aircraft, industrial plants, trains and cars can cause serious harm to life, limb, and property in the event of a software failure or incorrect software requirements. The traditional way to verify if the software is both reliable and safe is through testing, but a program can only accomplish so much. The solution is to employ intelligent testing. This study explores the theoretical underpinnings of software testability, software reliability and software safety, and discusses the practical assessment of these important software qualities. While the emphasis is on assessment of these qualities, the achievement of these qualities is also discussed.

Über diesen Titel

Über die Autorin bzw. den Autor

MICHAEL A. FRIEDMAN, PhD, is a Senior Staff Engineer with Hughes Information Systems, Fullerton, California, where he provides technical leadership in the development of safety- and reliability-critical systems. Prior to joining Hughes, he served for several years as a software consultant with Digital Equipment Corporation. An author of the book Reliability of Software Intensive Systems and the Military Handbook on Hardware/Software Reliability Assurance Control, Dr. Friedman received his doctorate in information and computer science from the University of California, Irvine. JEFFREY M. VOAS, PhD, is Director of Research at Reliable Software Technologies Corporation, Sterling, Virginia. From 1990 to 1992 he was a postdoctoral fellow with the National Research Council at NASA-Langley. Dr. Voas received his doctorate in computer science from the College of William and Mary.

Von der hinteren Coverseite

Is software quality testing really effective or just a waste of time? The skeptics conclude that it is an exercise in futility to try to measure the reliability and safety of these complex systems under all critical circumstances. They contend that quality assurance comes only through a strict adherence to rigorous development process models. In this groundbreaking book, Michael Friedman and Jeffrey Voas dispel that myth. They demonstrate that extremely accurate, cost–effective software quality testing can now be a reality, thanks to powerful new analytical tools.

Central to the approach outlined in Software Assessment is a sophisticated assessment optimization technique called testability analysis. Pioneered at the College of William and Mary and NASA by Jeffrey Voas, testability analysis predicts the likelihood that latent bugs will be detected during testing. Drawing upon their experiences working on various high–profile projects including air traffic control systems, an automated high–speed train–control system, and a CASE–generated autopilot system they describe how testability analysis is used to determine which tests work and which do not; how much testing should be done on a given program; which areas of a program (modules, lines of code, etc.) are the most testable and which are the least testable; and how to allocate precious resources. The authors also describe original techniques for designing and coding programs to maximize their testability and a new method of generating test cases to support testing and testability analysis.

Software Assessment offers a balanced presentation of theory and practice and is designed to function as either (continued on back flap) (continued from front flap) graduate–level text or professional reference. Featuring exhaustive coverage of the theoretical foundations of reliability, safety, and testability, it uses real–world examples, illustrations, and clear descriptions to explore all of the latest techniques for assessing those qualities.

Information technology and the software that makes it possible are vital aspects of our economic, political, and cultural lives. Software Assessment provides powerful new tools for assessing and enhancing the safety, reliability, and testability of these crucial resources.

Software Assessment

Breakthrough tools and techniques that make accurate, cost–effective software quality testing a reality

Written by two of the most prominent figures in the field of software quality testing, Software Assessment arms software designers and developers with cutting–edge tools and techniques for measuring and enhancing the safety, reliability, and testability of the programs they produce. Drawing upon their experiences working on major software projects at NASA and other agencies for which software quality is literally a matter of life and death, Michael Friedman and Jeffrey Voas show you how to:

• Use powerful testability tools and techniques to optimize the testing process
• Execute programs to perform automated quality testing
• Design and code programs for maximum testability
• Generate test cases to support testing and testability analysis
• And much more
