The problem is that there is not enough time spent on testing?  TRUE!, but I believe that there is a limit to where the programmer must test.  The ONLY person that can test a product properly is the user.  The problem is to get the user, which needs to do his normal job also, to spend the time.  Especially in the corporate world: If they find a bug 3 - 6 months after implementation, we as programmers sometimes wonder how they managed to use the product for so long, because, of course, the bug is now critical.
