The Model Based Testing (MBT) is an original approach where test cases are automatically generated from the specifications of the system under tests. These specifications take the form of a behavioral model allowing the test generator to determine, on the one hand, the possible and relevant execution contexts. On the other hand, to predict the effects of these executions on the system. This paper proposes new methodology to generate vulnerability test cases based on SysML model of Europay-Mastercard and Visa (EMV) specifications. Our main aim is to ensure that not only the features described by the EMV specifications are met, but also that there is no vulnerability in the system. To meet these two objectives, we automatically generated concrete tests basing on SysML models. Indeed, this paper highlights the importance of modeling EMV specifications. We opted for the choice of SysML modeling language due to its ability to model Embedded Systems through several types of diagrams. In our work we used state machine diagram to generate vulnerability test cases for a secure and robust system.

Abstract. Robustness testing aims at finding errors in a system under invalid conditions, such as unexpected inputs. We propose a robustness testing approach for Event-B based on specification mutation and model-based testing. We assume that a specification describes the valid inputs of a system. By applying negation rules, we mutate the precondition of events to explore invalid behaviour. Tests are generated from the mutated specification using ProB. ProB has been adapted to efficiently process mutated events. Mutated events are statically checked for satisfiability and enability using constraint satisfaction, to prune the transition search space. This has dramatically improve the performance of test generation. The approach is applied to the Java Card bytecode verifier. Large mutated specifications (containing 921 mutated events) can be easily tackled to ensure a good coverage of the robustness test space.
