A bestseller in its first two editions, Software Testing: A Craftsman’s Approach, Third Edition has been thoroughly revised and updated to highlight issues such as how Agile and XP development environments have radically changed the role of software testers by making testing integral to every phase of the development process. Coverage also includes model-based and test-driven development, reexamination of all-pairs testing, and explanation of the four contexts of software testing. The author provides new downloadable programs that demonstrate white-box, black-box and other fundamental types testing.
