Abstract or Description
Formal specification and verification techniques have been used successfully to detect feature interactions. We investigate whether feature-based specifications can be used for this task. Feature-based specifications are a special class of specifications that aim at modularity in open-world, feature-oriented systems. The question we address is whether modularity of specifications impairs the ability to detect feature interactions, which cut across feature boundaries. In an exploratory study on 10 feature-oriented systems, we found that the majority of feature interactions could be detected based on feature-based specifications, but some specifications have not been modularized properly and require undesirable workarounds to modularization. Based on the study, we discuss the merits and limitations of feature-based specifications, as well as open issues and perspectives. A goal that underlies our work is to raise awareness of the importance and challenges of feature-based specification.
