Network protocol interoperability testing based on contextual signatures and passive testing

Fatiha Zaidi, Emmanuel Bayse, Ana Cavalli
2009 Proceedings of the 2009 ACM symposium on Applied Computing - SAC '09  
This paper presents a methodology for interoperability testing based on contextual signatures and passive testing with invariants.  ...  To illustrate the application of the proposed approach, a real case study is proposed: the Wireless Application (WAP) protocol.  ...  The ISO 9646 standard [1] mentions that conformance testing can increase the probability of interoperability, but cannot guarantee the successful interaction between different implementations.  ...

Two approaches linking a test generation tool with verification techniques [chapter]

Marylène Clatin, Roland Groz, Marc Phalippou, Richard Thummel
1996 Protocol Test Systems VIII  
Preliminary results on non-trivial protocols are commented.  ...  The first method is a kind of symbolic execution. The second method consists in linking the test generation tool with a tool permitting sophisticated types of reachability analysis.  ...  ISO has established a methodology in its IS-9646 standard.  ...

A Model-Based Approach for Robustness Testing [chapter]

Jean-Claude Fernandez, Laurent Mounier, Cyril Pachon
2005 Lecture Notes in Computer Science  
This generation technique is inspired from the ones used in (classical) conformance testing -already implemented in several tools. This framework is illustrated on a small example.  ...  Robustness testing is a part of the validation process which consists in testing the behavior of a system implementation under exceptional execution conditions in order to check if it still fulfills some  ...  This work was partly initiated in a joint work on robustness testing inside a French action supported by the Cnrs and gathering members of Irisa, Laas, Labri, Lri and Verimag laboratories (http://www.laas.fr  ...
