Studying the co-evolution of production and test code in open source and industrial developer test processes through repository mining

Many software production processes advocate rigorous development testing alongside functional code writing, which implies that both test code and production code should co-evolve. To gain insight in the nature of this co-evolution, this paper proposes three views (realized by a tool called TeMo) that combine information from a software project's...

On How Developers Test Open Source Software Systems

Engineering software systems is a multidisciplinary activity, whereby a number of artifacts must be created — and maintained — synchronously. In this paper we investigate whether production code and the accompanying tests co-evolve by exploring a project’s versioning system, code coverage reports and size-metrics. Three open source case studies...
