>Why do you continually insist that this is possible, when nearly every text on testing software ever written insists that it is not? You cannot test for every condition in a non-trivial piece of software. You won't live that long. If someone thinks they've tested every condition in their software, they are deluding themselves. They may have tested the most common conditions, but not every one.

Just look at how long it took WOPR to figure out, by trying all the possibilities of tic-tac-toe no less then simulated global thermonuclear war, that the only way to win was not to play. < bg >
