Several people at C4 suggested there should be a talk on testing next year. But as @arclite tweeted, C4 is a state of mind. So I'm not going to wait until next year. I'm not going to make you wait until next year. You, Indie Developer, need some advice on testing your Mac apps now. As I develop my talk for next year (which may or may not actually occur), I'll post the content here. Expect the first installment within a week.
