I believe in the concept of what I call Lucid Testing. I even tried to promote my own BDD-style tool solution called — what else? — Lucid. The focus on lucid testing is making testing a design activity. As such an activity, testing makes the business domain — and how that business domain provides value — lucid (expressive and understandable) to anyone who has a vested interest. Core to these ideas is that testing is a design activity and that the primary value of testing is as a communication activity.
