Ask HN: What is test driven development to you?

[karuth]

HN'ers, I would like to hear from you all about testing methodologies, and what you consider as best practice. Do you see any advantage of the test-first paradigm? What is fad and what do you find practical?

I think I agree with DHH:

Testing is a Pareto thing: you want to be on the right place on that curve or else you're probably sinking too much effort into it, and not enough on other things.

Thanks for the article. It is very illuminating.

I hear a lot of buzz on TDD. But I think TDD is not the end. There are complexities in application which is sometimes hard to comprehend before a module is put in place. In those cases DDT (development driven testing) might actually make sense.
