Abstract
Ensuring the consistency between Graphical User Interfaces (GUIs) and user requirements is a critical aspect of the design process since it is through the GUIs that users perceive the system and experience the available features in order to achieve their goals. This paper presents an approach based on Behavior-Driven Development (BDD) which employs an ontology in order to provide automated assessment for web GUIs. The approach has been evaluated by exploiting user requirements described by a group of experts in the flight tickets e-commerce domain. Such requirements gave rise to a set of User Stories that have been used to automatically assess the GUIs of an existing web system for booking business trips. The results have shown our approach was able to identify different types of inconsistencies in the set of GUIs analyzed, allowing to build an effective correspondence between user requirements and their representation on the GUI.
