When we changed to Extreme Programming a few ages ago, we made grave mistakes taking for granted that automated testing was enough, and shipped numerous woeful releases. We learned to a greater extent around testing (and how to improve it) from those second-rate releases than from the following satisfactory releases.

I know your web site has little to do with my post, but you've expressed your flattery so well, I've decided to approve your comment for posting. Merry Xmas!

This looks like a bug that Freescale should have caught with normal boundary tests during unit testing. How does it work on day 1 of a normal year? How does it work on day 1 of a leap year? How does it work on the last day of a normal year? how does it work on a normal day of a leap year. If they take into account the extra second added this year, then that would be another test. One of the primary reasons for using a library is that it is, in theory, tested and known to work. I don't typically unit test a third party library. I read the API, I make sure I understand how to use it and then I use it. I unit test my own code. Are you saying you exhaustively test every library that you use in a given programming language?
