Where did you learn to unit test? How did you learn?

In the case of bug-tickling tests, one of the big selling points
is that they let you make sure bugs don't come back.  This is an
easier sell if you can demonstrate (say, by analysis of historical
bug reports) that in the past bugs have been fixed and come back
again.  Even better if you can determine how much time was spent
troubleshooting reintroduced bugs from scratch.
