Enhancing a gamified tool for UML modeling education

Unified Modeling Language (UML) Use Case and Class Diagrams are fundamental modeling notations in Software Engineering (SE) education due to their importance for requirements and model-based engineering, yet their relevance is underestimated by students, who tend to dismiss the topic as secondary. Gamification has been adopted to make modeling education more appealing, but existing tools focus almost exclusively on class diagrams, leaving support for use cases and other notations unexplored. In 2025, we designed UMLegend, a gamified tool for class diagrams that offered dynamic feedback to help students learn correct modeling practices and multiple long-term mechanics to increase engagement, and performed a study with the tool. With this paper, we describe how we enhanced UMLegend following the results of the experiment so that it can support more modeling languages, with use case diagrams being added to the type of available exercises in the tool. The revised version has been refactored to have a modular architecture, to make it easier to add other software engineering topics and additional modeling notations. We also describe the potential impact we expect the new version to have, and outline a longitudinal study we intend to perform in 2026 where we will assess whether long-term UML gamification leads to improved student performance.

Gamifying Testing in IntelliJ: A Replicability Study

Gamification is an emerging technique to enhance motivation and performance in traditionally unengaging tasks like software testing. Previous studies have indicated that gamified systems have the potential to improve software testing processes by providing testers with achievements and feedback. However, further evidence of these benefits across different environments, programming languages, and participant groups is required. This paper aims to replicate and validate the effects of IntelliGame, a gamification plugin for IntelliJ IDEA to engage developers in writing and executing tests. The objective is to generalize the benefits observed in earlier studies to new contexts, i.e., the TypeScript programming language and a larger participant pool. The replicability study consists of a controlled experiment with 174 participants, divided into two groups: one using IntelliGame and one with no gamification plugin. The study employed a two-group experimental design to compare testing behavior, coverage, mutation scores, and participant feedback between the groups. Data was collected through test metrics and participant surveys, and statistical analysis was performed to determine the statistical significance. Participants using IntelliGame showed higher engagement and productivity in testing practices than the control group, evidenced by the creation of more tests, increased frequency of executions, and enhanced utilization of testing tools. This ultimately led to better code implementations, highlighting the effectiveness of gamification in improving functional outcomes and motivating users in their testing endeavors. The replication study confirms that gamification, through IntelliGame, positively impacts software testing behavior and developer engagement in coding tasks.

Gamified GUI testing with Selenium in the IntelliJ IDE: A Prototype Plugin

Software testing is a crucial phase in software development, enabling the detection of issues and defects that may arise during the development process. Addressing these issues enhances software applications' quality, reliability, user experience, and performance. Graphical User Interface (GUI) testing, one such technique, involves mimicking a regular user's interactions with an application to identify defects. However, GUI testing is often underutilized due to its perceived repetitiveness, error-proneness, and lack of immediate feedback on test quality. In recent years, gamification-incorporating game elements in non-game contexts to boost interest, motivation, and engagement-has gained traction in various fields, including software engineering and education. This paper presents GIPGUT: a prototype of a gamification plugin for IntelliJ IDEA, an Integrated Development Environment (IDE) that supports scripted GUI testing. The plugin enhances testers' engagement with typically monotonous and tedious tasks through achievements, rewards, and profile customization. A preliminary prototype evaluation was conducted with a small group of users to assess its usability and the impact of gamification on the GUI testing process. The results indicate high usability and positive reception of the gamification elements. However, due to the limited sample size of participants, further research is necessary to understand the plugin's effectiveness fully.
