Testing variability intensive systems is a formidable task due to the combinatorial explosion of feature interactions that result from all variations. We developed and validated an approach of combinatorial test generation using Multi-Perspective Feature Models (MPFM). MPFMs are a set of feature models created to achieve Separation of Concerns within the model. This approach improves test coverage...
In this paper we propose a behavioural model, namely the generalized extended modal transition systems, as a basis for the formalization of different notions of variability usually present in product families definitions. In particular, a GEMTS is able to define a family of products by telling at any state of the system whether some (and how many) transitions are optional or mandatory for any derived...
