Magic Numbers: Integers
After many moons of sitting in a queue somewhere, the MSDN Tester Center just posted my intro article on special numbers you probably want to think about when running tests. The paper addresses several interesting domains of integers (all the way up to 64-bits) and gives you samples of important values to use:
In testing software, we often miss an entire class of bugs just because we don't happen to think about one category of inputs and how they might adversely affect the system. To help combat this in with my own tests, I've pulled together a listing of numbers which are good to use in testing for various independent reasons.

About joshpoley
Josh Poley has been a software tester (SDET) at Microsoft since 1998. He initially worked on the very first version of the Passport authentication service (currently called Windows Live ID). Then, in the spring of 2000, Josh moved over and joined a small handful of people who were starting to work on a project code-named Xbox. His initial responsibilities covered various pieces of the low level operating system (file systems, peripheral communication, etc.). Shortly after the Xbox game console launched in 2001, Josh took over as lead of the Kernel Test Team and remained in charge of validating the core operating system throughout the development and launch of the Xbox 360. Then, in the spring of 2007, Josh joined the Zune group as a Test Architect, where he helped solve various problems across the four main test teams in the organization. After a year in Zune, Josh went back to Xbox to help solve some more hard problems there.
