Yesterday's testing poll already has interesting results, but you have to have a LJ account to complete it. brian d foy is creating an open version of said poll. Based on some of the poll replies, I've made a slight adjustment to the poll and when it's done, we'll start pushing that URL out there to get a wider scope.
The one thing about that poll which really shocked me, so far, is that almost 25% of respondents with test suites report that not all tests pass. Wow. Just wow.
