VarXplorer: reasoning about feature interactions

Feature interactions occur when a feature behavior is influenced by the presence of another feature(s). Typically, interactions may lead to faults that are not easily identified from the analysis of each feature separately, especially when feature specifications are missing. In this paper, we propose VarXplorer, an iterative approach that supports developers to detect internal interactions on control and data flow of configurable systems, by means of feature-interaction graphs and an interaction specification language.
