        This method tests the execution of a somewhat realistic use of the Modelverse and its core functions, through the use of a simple Petri nets example.
        First, Petri net metamodels are created for both the design language and the runtime language.
        Both languages only differ marginally from each other, with the runtime language only adding information on the currently selected transition for execution.
        Afterwards, a trivial Petri net model is created in the design language.
        This part tests the domain-specific and meta-modelling concepts of the Modelverse.

        After all models are created, transformations are defined to map between both languages: from design to runtime, and vice versa.
        Additional transformations are created for in-place model simulation and the printing of a Petri net model.
        This tests the modification of models, through the use of model transformations.
        Due to the use of a separate design and runtime language, we test exogenous transformations.
        The simulation transformation takes a single step in the Petri net model, by firing one of the applicable transitions, and therefore tests endogenous transformations.
