Image Cannot Displayed Doug co-authored the Domain Testing Workbook with Cem Kaner and Sowmya Padmanabhan. The book contains nearly 500 pages describing equivalence class analysis (a.k.a. domain analysis); the most widely taught (but superficially treated) software testing technique. The technique is used to dramatically reduce the number of tests required while at the same time making the tests more powerful. Standard training on equivalence class analysis does not extend to analysis of real problems like printer configuration dialogues, open file options, or sorting. The workbook describes a systematic method for equivalence analysis with exercises and 30 fully worked out examples of real-world testing problems.

The workbook provides comprehensive explanations and background for each task including examples and exercises. Although not all tasks are needed for all analyses, understanding the tasks in context leads to much better testing, even when they are not specifically employed. The book is for people serious about becoming world-class programmers or testers, whatever their current level of experience.
