Asynchronous testing of real-time systems

Abstract

Conformance testing is an operational way of determining whether an implementation conforms to the specification or not. It has a rich underlying theory wherein the specification and the implemen- tation under test (IUT) are each modeled by a timed automaton with inputs and outputs (TAIO), a variant of the classical timed automaton [1]. Test cases generated from the specification TAIO are symbolically executed against the implementation TAIO. Depending upon how test cases interact with the IUT, testing can be synchronous or asynchronous. In synchronous testing a test case interacts with the IUT directly, whereas in asynchronous testing a test case interacts with the IUT through a pair of first-in-first-out (FIFO) channels. Different approaches for synchronous testing of real-time systems have already been proposed [5],[7],[4],[8]. In this paper we propose an approach which is aimed at testing real-time systems asynchronously (i.e., remotely through some medium)
