>>Software companies do have testing departments. We have one, and I know MS has one. Mike Stewart and John Koziol are testers in the Fox group. Note that there are others. You should read Mike's testing article in a recent CoDe. I think it was the Jan/Feb issue.

>I might have been clearer in what I meant about testing departments. I meant to say that there were departments who purpose was to test software and not approve the software for release until thorough testing was completed and the product was certified by that department to be free of all known bugs.

How can you do that? Take something as complicated as Windows. Removing all known bugs would mean a new version would never get released.
