A Case Study on Feature-Aware Verification

In this thesis, we report of a case study on feature-aware verification. Featureaware verification is the formal verification of a feature-oriented software system on a feature-modular basis. Feature-modular verification means, that specifications are assigned to a particular feature and use feature-local knowledge only. That concerns the features’ awareness of other features in a particular product of a software product line. Feature-local knowledge means, that a feature is only aware of features that it depends on. The verification process includes software model checking, in particular CPAChecker is used. We evaluate the feasability of feature-aware verification by means of an e-mail system case study, which is based on Hall’s specification of an email system from [Hal05]. Thereby we detect undesired feature interactions by feature-modular specifications.
