I agree much with the article; it was the parent comment I was replying to. I disagree with the idea that a tester shouldn't consider hard-to-find bugs, or performance bugs. I disagree somewhat with the idea that a programmer error or coverage issue is an entirely independent issue from other bugs - if there's no possible manifestation, it's not a bug, and if there is a manifestation, then it's possible to find under another 'class' of bug. I fully agree that we won't execute tests to find all possible bugs. But similarly, code review doesn't find all code errors.
