And So To Testing....
“Testing is an infinite process of comparing the
invisible to the ambiguous in order to avoid the
unthinkable happening to the anonymous”

“we have as many testers as we have developers. And testers
spend all their time testing, and developers spend half their
time testing. We're more of a testing, a quality software
organization than we're a software organization.”
Bill Gates (Information Week, May 2002)
