I suspect people are (edit: were) downvoting you because of backlash to TDD (and other testing ideology) zealots. Knowing how to test software, how to write software that can be easily tested, how to systematically reproduce bugs to can find their underlying cause, etc. is excellent advice. Just don't focus on specific tools for testing so much that you miss cultivating good analytical skills (or forgive sloppiness).
