Is there a difference between TDD and Test First Development (or Test First Programming)?

Question

Both ideas sound very similar to me, but there might be subtle differences or the exact same thing, explained in different ways. What is the relationship between TDD and Test Fi

Answer 1

They are basically different names describing the same thing - well, in fact five names, as the last D can stand for Design as well as for Development.

Test First was the term used originally, especially in the context of Extreme Programming, for the test-code-refactor cycle. The name Test Driven Development has been proposed - and quickly adopted - later, to stress the fact that TFD is - and always has been - more of a design strategy than a testing strategy.

Obviously today some people have different connotations for those two terms, but that wasn't the intent behind their existance, and I wouldn't rely on it being common knowledge (because it's not). In fact, I'd rather see the term TFD as being deprecated.
