Industrial Study on Test Driven Development: Challenges and Experience

• Conducting empirical studies in industry always presents a major challenge for many researchers. Being a graduate student does not make things any easier. Often due to the lack of experience, credibility or just very limited networking, graduate students do not receive many opportunities to directly collaborate with industry and experiment their theoretical models in a realistic environment. On the other hand, empirical research conducted in an academic settings is often criticised for using students as subjects and working with a small sample size, thus creating major validity threat of the published results. In this paper we are presenting an experience report from an industrial empirical study conducted at Infosys Ltd., India with the support of their global internship program for graduate students, InStep. Focus of the paper is to present several challenges arisen before, during, and after the study, requiring an immediate attention in order to have a successful experiment completion. We also discuss and elaborate the data analysis results and its implication to our current research activities.
