Testing the boundaries of a specific domain

The increasing use of domain-specific modeling to increase efficiency in modeling multiple concerns, increases the need to correctly formalize domain models. Domains are modeled as metamodels, which capture the domain's modeling spaces, i.e. the set of all models which structure conforms to the description specified in the metamodel. However, there is currently no systematic method to test that a metamodel captures all the correct models of the domain and no more. Our most recent contribution to testing focuses on the automatic selection of models in the modeling space captured by a metamodel. We adapt metaheuristic search to generate a set that covers as many representative situations as possible, while staying as small as possible.
