The definition is you write or amend a test before making the code change that makes it pass. That's it. It says nothing about the type of test you write. Personally i do it with literally every type of test that i write - acceptance, integration, unit. If you write a decent test, yes, TDD is always valuable. If you TDD with shitty tests, not so much, but that isnt really an issue with TDD.
