Abstract

Engineering software systems is a multidisciplinary activity, whereby a number of artifacts must be created — and maintained — synchronously. In this paper we investigatewhether production code and the accompanying tests coevolveby exploring a project’s versioning system, code coveragereports and size-metrics. Our main aim for studyingthis co-evolution is to create awareness with developers andmanagers alike about the testing process that is followed.We explore the possibilities of our technique through twoopen source case studies and observe a number of differentco-evolution scenarios. We evaluate our results both withthe help of log-messages and the original developers of thesoftware system.
