Learn the Secrets of Mainframe Testers!Reliability and continuous availability have become crucial for computer software in the information economy. Wellpublicized failures from both industry and government have underscored the need for missioncritical software to be thoroughly tested before being released into the marketplace. When it comes to industrialstrength reliability, no computer system is more renowned than the mainframe. But for years the actual approaches used to test mainframe software have been kept under wraps. What techniques are used? How do the teams in mainframe development labs test their systems to ensure they will deliver such extreme levels of robustness? How can these lessons be applied to other software projects?Software Testing Techniques: Finding the Defects that Matter answers these questions and provides practical testing techniques for achieving robust reliability with any largescale software project. Written in a friendly, accessible style, the book highlights areas such as devising attacks to validate data integrity, wreaking havoc to ensure recoverability, exploiting virtualized environments to improve test efficiency, the tug of war between finding defects and meeting schedules, and approaches for emulating customer environments to find the most critical defects. Focusing on reallife techniques illustrated through examples and case studies gleaned from the authors` experiences with large server testing and operation, software engineers will discover tried and true techniques that are used for testing multimilliondollar commercial software products.Covers multiple phases of testing that are relevant to largescale projects, with an emphasis on the systemwide testing that is critical to establishing the reliability of enterpriseclass software.Provides practical testing techniques for achieving robust reliability with largescale software projects.Focuses on realworld issues, problems, and solutions.Emphasizes approaches for finding and removing the defects that matter most to customers.Highlights techniques for devising attacks to validate data integrity, wreaking havoc to ensure recoverability, developing effective test programs, exploiting virtualized environments to improve test efficiency, and emulating customer environments to find the most critical defects.ABOUT THE AUTHORSScott Loveland, Geoffrey Miller, Richard Prewitt, Jr., and Michael Shannon have collectively spent more than 70 years in the software testing trenches. They have consulted on best practices in test and system availability to customers ranging from worldwide corporations to the U.S. Department of Defense. They currently hunt bugs in the IBM mainframe development laboratory in Poughkeepsie, New York.
