IntelliGame in Action: An Experience Report on Gamifying JavaScript Unit Tests

This paper investigates the integration and assessment of Intelligame, a gamification plug in initially designed for Java development, within the realm of JavaScript unit testing. We aim to verify the gener-alizability of Intelligame to JavaScript development and to provide valuable insights into the experiment's design. For this, we first customize Intelligame for JavaScript, and then conduct a controlled experiment involving 152 participants utilizing the Jest testing framework, and finally examine its influence on testing be-havior and the overall developer experience. The findings from this study provide valuable insights for improving JavaScript testing methodologies through the incorporation of gamification.
