Synthesis of Distributed Testers from True-concurrency Models of Reactive Systems
Résumé
Automatic synthesis of test cases for conformance testing has been principall- y developed with the objective of generating sequential test cases. In the distributed system context, it is worth extending the synthesis techniques to the generation of multiple testers. We base our work on our experience in using model-checking techniques, as successfully implemented in the TGV tool. Continuing the works of A. Ulrich and H. König, we propose to use a true-concurrency model based on graph unfolding. The article presents the principles of a complete chain of synthesis, starting from the definition of test purposes and ending with a projection onto a set of testers.
