Conceptualization of Multi-User Collaborative GUI-Testing for Web Applications

System testing through the Graphical User Interface (GUI testing) is often overlooked in real-world software projects. The mechanics proper of Gamification are often adopted to increase the motivation and engagement of testers in such scenarios. There is however little evidence in the literature about collaborative - rather than competitive - Gamification mechanics for software testing. In this manuscript, we describe a prototype for a collaborative GUI-testing prototype for web applications based on micro-tasks, of which we perform a small-scale preliminary evaluation. We find that the use of a microtask-based collaboration environment incentivizes depth-first testing of web applications and increases local coverage. We also collected positive experience reports from practitioners about the practice.
