"You don't spend time writing unit tests, you save time writing unit tests!"

"If you don't write a unit test, how do you know its done?"

"If it is not broken, you probably haven't written a good enough unit test!"

"If at first you don't succeed, you suck at writing unit tests."

"Writing a unit test at the end is like closing the barn door after your horse has eaten your veggie garden"

"When a unit test fails, you know you are on the road to success!"
