BDD is, IME, only really good for testing UI behavior (I've seen some pretty decent JS BDD testing frameworks, but have limitex xp with them). It can be good at that because those behaviors can usually be expressed well enough in natural language. But I've seen it shoehorned into data-centric UI-less applications that are just a massive pain to deal with. Half the point of most testing frameworks is getting more done with less typing/overhead, but Cucumber and BDD is sorta the exact opposite: do less with more typing by trying to describe complex concepts in natural language. Cucumber mostly exists to upsell naive MBAs and project managers on their "pro" tools.
