PHASE 1—The purpose of testing is to show that the software works. PHASE 2—The purpose of testing is to show that the software doesn’t work. PHASE 3—The purpose of testing is not to prove anything, but to reduce the perceived risk of not working to an acceptable value. PHASE 4—Testing is not an act.
• Testing is a critical element of software development life cycles • called software quality control or software quality assurance • basic goals: validation and verification • validation: are we building the right product? • verification: does “X” meet its specification?
There is no one standard textbook on software testing, and this book is the result of many years of extracting and interpreting test techniques from a wide and varied number of sources. These include testing classics such as The Art of Software Testing by Myers, Software Testing by Roper, and Testing Object-Oriented Systems by Binder;
of Software Testing alone gave the industry a long-lasting, foundational guide to one of the most important computer topics: How do you ensure that all of the software you produce does what it was designed to do, and—
This extensively classroom-tested text takes an innovative approach to explaining software testing that defines it as the process of applying a few precise, general-purpose criteria to a structure or model of the software.
