Regression testing is essential for software maintenance, but is often underrepresented in higher education. This study examines the understanding and application of regression testing among 176 third-year computer science students. Using the Goal-Question-Metric (GQM) framework, we conducted an empirical study with three tasks: test suite creation, bug fixing, and regression test selection, alongside questionnaires with open-ended, closed-ended, and Likert-scale responses. Results show that students mainly selected tests based on changes, affected methods, and dependencies, while reporting positive experiences with teamwork, problem-solving, and skill development. The findings highlight the value of hands-on, collaborative activities in reinforcing both technical and soft skills, suggesting that structured regression exercises can bridge the gap between academic instruction and industry needs.
