In this paper, we present a model-based testing tool resulting from a research project, named TASCCC. This tool is a complete tool chain dedicated to property-based testing in UML/OCL, that integrates various technologies inside a dedicated Eclipse plug-in. The test properties are expressed in a dedicated language based on property patterns. These properties are then used for two purposes. First, they can be employed to evaluate the relevance of a test suite according to specific coverage criteria. Second, it is possible to generate test scenarios that will illustrate or exercise the property. These test scenarios are then unfolded and animated on the Smartesting's Certify It model animator, that is used to filter out infeasible sequences. This tool has been used in industrial partnership, aiming at providing an assistance for Common Criteria evaluations, especially by providing test generation reports used to show the link between the test cases and the Common Criteria artefacts.

This paper describes the Tobias tool. Tobias is a combinatorial test generator which unfolds a test pattern provided by the test engineer, and performs various combinations and repetitions of test parameters and methods. Tobias is available on-line at tobias.liglab.fr . This website features recent improvements of the tool including a new input language, a traceability mechanism, and the definition of various ``selectors'' which achieve test suite reduction.
