A Metric Framework for the Gamification of Web and Mobile GUI Testing

System testing through the Graphical User Interface (GUI) is a valuable form of Verification & Validation for modern applications, especially in graphically-intensive domains like web and mobile applications. However, the practice is often overlooked by developers mostly because of its costly nature and the absence of immediate feedback about the quality of test sequence. This paper describes a proposal for the Gamification of exploratory GUI testing. We define - in a tool and domain- agnostic way - the basic concepts, a set of metrics, a scoring scheme and visual feedbacks to enable a gamified approach to the practice; we finally discuss the potential implications and envision a roadmap for the evaluation of the approach.
