Re: [extremeprogramming] The principle behind How Test-Driven Development Works

I prefer "test-driven" over "test-first". Tests define what needs to be 
accomplished, in tiny slices, in some executable "clear when it's done" 
form. There's TDD with unit tests at the code task level, there's TDD 
with acceptance tests at the user story level, and there's TDD with 
business goals at the product level, e.g., reduced user error or 
increased usage of some feature.
