This book is not pleasing to look at (having been produced directly from a computer text file), but it provides an introductory, nontechnical description of the testing process. Organized by software lifecycle phases, it includes chapters on testing requirements, designing tests from requirements, testing in the design stage, functional testing, tests designed from the program code, from integration to system testing, and testing with the operational phase. The author's preface describes the book as "intended for the person involved in the production of
software, students of computing and software engineering, and the practicing software engineer."
