“…The approach has also been extended and adapted to assess other early artifacts such as GUI prototypes and late artifacts such as final GUIs [39], [34], [37], [36], [40]. As an integrated approach, the same set of BDD stories is assigned to automatically assess task models, GUI prototypes in different levels of abstraction, and final GUIs, ensuring a consistent verification, validation and testing (VV&T) approach for interactive systems with high availability of tests and instantaneous feedback about the consistency of artifacts regarding the user requirements.…”
