Micro-services are a common architectural approach to software development\ntoday. An indispensable tool for evolving micro-service systems is A/B testing.\nIn A/B testing, two variants, A and B, are applied in an experimental setting.\nBy measuring the outcome of an evaluation criterion, developers can make\nevidence-based decisions to guide the evolution of their software. Recent\nstudies highlight the need for enhancing the automation when such experiments\nare conducted in iterations. To that end, we contribut…
