Towards an Automated Test Generation with Delayed Transitions for Timed Systems

In this paper we analyze the influence of the urgency in the timed transitions, and as consequence, in the test suite generation. As result, we formalize rules to generate sequences where the messages exchanged may be instantaneous or delayed. In addition, the generated scenarios are able to detect timing faults. For test generation, we use a prototype tool called HJ2IF. It is based on a test purpose algorithm, called hit-or-jump and it is applied for systems specified using Intermediate Format language (IF).
