On-the-Fly Formal Testing of a Smart Card Applet

This paper presents a case study on the use of formal methods in specification-based, black-box testing of a smart card applet. The system under test is a simple electronic purse application running on a Java Card platform. The specification of the applet is given as a Statechart model, and transformed into a functional form to serve as the input for the on-the-fly test generation, -execution, and -analysis tool GAST. We show that automated, formal, specification-based testing of smart card applets is of high value, and that errors can be detected using this model-based testing.
