MATERA2-AlfTester: An Exhaustive Simulation and Test Generation Tool for fUML Models

The Foundational Subset for Executable UML Models (fUML) and the Action language for fUML (Alf) can be used for creating executable models in the Eclipse-based UML editing tool called Papyrus. An fUML execution engine in Papyrus, such as Moka, allows to simulate or execute fUML models along with their associated Alf code. However, for exhaustive simulation of such models, one must provide input data required to reach and cover all important elements not only in the graphical fUML models, but also in the textual Alf code. In this paper, we present MATERA2-AlfTester, an Eclipse-plugin for exhaustive simulation and test generation for fUML models. MATERA2-AlfTester integrates with Papyrus and Moka tools and extends their functionally by allowing one to automatically generate test data, test suite with test oracle, and partial Java code at design time. We also present the simulation and testing process of MATERA2-AlfTester with the help of an example and demonstrate how exhaustive simulation and test generation with MATERA2-AlfTester can help designers in assessing and improving the quality of fUML models.
