Section: Application Domains
Our research on test generation was initially proposed for conformance testing of telecommunication protocols. In this domain, testing is a normalized process  , and formal specification languages are widely used (SDL in particular). Our test generation techniques have already proved useful in this context, going up to industrial transfer. New standardized component-based design methodologies such as UML and OMG's MDE increase the need for formal techniques in order to ensure the composionality of components, by verification and testing. Our techniques, by their genericity and adaptativity, have also proved useful at different levels of these methodologies, from component testing to system testing. The telecommunication industry now also tries to provide more and more services to the users. These services must be validated. We are involved with France Telecom R & D in a project on the validation of vocal services (see 7.1 ). Very recently, we also started to study the impact of our test generation techniques in the domain of network security. More specifically, we believe that testing that a network or information system meets its security policy is a major concern, and complements other design and verification techniques.
