Description

This book will teach you how to test computer software under real-world conditions. The authors have all been test managers and software development managers at well-known Silicon Valley software companies. Successful consumer software companies have learned how to produce high-quality products under tight time and budget constraints. The book explains the testing side of that success.

Who this book is for:
* Testers and Test Managers
* Project Managers-Understand the timeline, depth of investigation, and quality of communication to hold testers accountable for.
* Programmers-Gain insight into the sources of errors in your code, understand what tests your work will have to pass, and why testers do the things they do.
* Students-Train for an entry-level position in software development.

What you will learn:
* How to find important bugs quickly
* How to describe software errors clearly
* How to create a testing plan with a minimum of paperwork
* How to design and use a bug-tracking system
* Where testing fits in the product development process
* How to test products that will be translated into other languages
* How to test for compatibility with devices, such as printers
* What laws apply to software quality

About the Authors 480

"I enjoyed reading Testing computer software. The text contains numerous highlights Offering practical advice, authoritative figures you can cite to customers and higher management, and entertaining anecdotes to share with coworkers Although some sections need updating, I still think it is a valuable training and reference source for software testers, managers, and developers." --Diomidis Spinellis; IEEE software magazine (May /June 2001))

"Deep insight and a great deal of experience is contained in this book" (Database & Network Journal, Vol 30/5 2000)
