NIST SP 800-142 October 2010 Printed in COLOR Combinatorial testing is a method that can reduce cost and increase the effectiveness of software testing for many applications. The key insight underlying this form of testing is that not every parameter contributes to every failure and most failures are caused by interactions between relatively few parameters. Empirical data gathered by NIST and others suggest that software failures are triggered by only a few variables interacting (6 or fewer). This finding has important implications for testing because it suggests that testing combinations of parameters can provide highly effective fault detection. Why buy a book you can download for free? First you gotta find it and make sure it''s the latest version (not always easy). Then you gotta print it using a network printer you share with 100 other people - and its outta paper - and the toner is low (take out the toner cartridge, shake it, then put it back). If it''s just 10 pages, no problem, but if it''s a 250-page book, you will need to punch 3 holes in all those pages and put it in a 3-ring binder. Takes at least an hour. An engineer that''s paid $75 an hour has to do this himself (who has assistant''s anymore?). If you are paid more than $10 an hour and use an ink jet printer, buying this book will save you money. It''s much more cost-effective to just order the latest version from Amazon.com This public domain material is published by 4th Watch Books.
