So my buddies Dan Gilkerson and Llewellyn Falco [defunct link: http://www.spunlabs.com/] have been doing some brilliant, ground breaking work on advancing the state of unit testing and TDD with a concept they call Approval Testing [defunct link: http://blog.approvaltests.com/].

unit testing -> TDD -> BDD -> Approval Testing
Dan wrote a parody of the song Let It Be.
The Music Video: _Let it BBD
