Fokus!MBT - a multi-paradigmatic test modeling environment

UML modeling environments for doing model-based testing are often not very comfortable to use and burden some knowledge about the internals of UML to the users, respectively test engineers. Test engineers, however, are seldom experts in UML, thus, the gain of efficiency model-based testing approaches entail, is reduced by a too generic tooling. The tool Fokus!MBT, developed by the competence center MOTION of Fraunhofer FOKUS, is a multi-paradigmatic test modeling environment based on the UML Testing Profile, an OMG-adopted industry-driven notation for model-based testing. Fokus!MBT simplifies the creation and authoring of test models with methodology-specific support. It is built on top of Eclipse Papyrus, a powerful open source UML modeling environment, which, in turn, relies on the Eclipse Modeling Framework and the Graphical Modeling Framework. This paper provides deep insights into the basic concepts and technical realization of Fokus!MBT as well as into the lessons we have learned during development and application.
