Informal Summary

In this short paper (2-pages), we investigate ethical issues with under-performing regression test selection: Who is responsible if the test selection is poor and would explicability support taking responsibility? How can we know that an AI-powered or automated regression test selection is not biased and would supervision help? Have all the necessary stakeholders participated in the development and would diversity improve the tool?

Test automation is common in software development; often one tests repeatedly to identify regressions. If the amount of test cases is large, one may select a subset and only use the most important test cases. The regression test selection (RTS) could be automated and enhanced with Artificial Intelligence (AI-RTS). This however could introduce ethical challenges. While such challenges in AI are in general well studied, there is a gap with respect to ethical AI-RTS. By exploring the literature and learning from our experiences of developing an industry AI-RTS tool, we contribute to the literature by identifying three challenges (assigning responsibility, bias in decision-making and lack of participation) and three approaches (explicability, supervision and diversity). Additionally, we provide a checklist for ethical AI-RTS to help guide the decision-making of the stakeholders involved in the process.
