BDD

BDD aims to bridge the gap between the differing views of computer systems held by Business users and Technologists. It is deeply rooted in the success of TDD and is influenced by ideas like DomainDrivenDesign. Its focus is on minimizing the hurdles between specification, design, implementation and confirmation of the behaviour of a system. Thus enabling the incremental delivery of business systems, and in particular in allowing teams new to agile development to quickly get up to speed using these extremely productive techniques... This focus on behaviour ahead of testing is a focus on the real value in TDD, and in our experience is the mark of the genuinely experienced TDD practitioner.
