Understanding TDD in academic environment

Abstract

Several studies have reported positive experiences with Test-Driven Development (TDD) but the results still diverge. In this study we aim to improve understanding on TDD in educational context. We conducted two experiments on TDD in a master's level university course. The research setting was slightly changed in the second experiment and this paper focuses on comparing the differences between the two rounds. We analyzed the students' perceptions and the difficulties they faced with TDD. The given assignment clearly affected the students' reflections so that the more difficult assignment evoked a richer discussion among the students. Additionally, some insights into teaching TDD are discussed.
