Every book I read by a real-world programmer - never does this. They always put testing in a separate chapter or never address it at all, example: programatic programmers.

Even any tutorials online or in a user group - it's never done. It's always talked about. I come from a engineering background so I really wanted to programming the "right" way. But here is so little code that includes testing that I can use to "tutor" myself. Even opensource.

I find this very odd.
