Model-based approach for automated test case generation from visual requirement specifications

Digital applications exhibit characteristics of rapid evolution, a multitude of stakeholders and emphasis on user experience. Role based access and data visualization is an important application feature. With increased focus on user experience, industry is seeing a growing trend towards visual approaches for documenting and validating requirements. A visual approach creates better synergy between various stakeholders but at the same time poses various challenges to testing. In this paper, we present a graph based modeling technique to create models from visual requirement specifications (or prototypes). The technique also generates test cases from these models using the semantics of the User Interface Components and behavioral events. The paper demonstrates the approach using a case study.
