torte: Reproducible Feature-Model Experiments à la Carte

Feature modeling is crucial to understand and manage the variability in configurable software systems. However, existing tools for the automated analysis of feature-model formulas still face significant challenges, especially when applied to large and evolving codebases such as the Linux kernel’s. In this paper, we contribute torte, an open-source tool that addresses some of these challenges. To this end, torte integrates existing tools and original contributions into a single experimentation platform. Thus, torte facilitates reproducible and flexible feature-model experiments, which we showcase in various successful research evaluations. In particular, torte finally enables researchers to analyze almost the entire history of the Linux kernel’s feature model, among other systems.
