An orchestrator in a Web Service system is a locally deployed piece of software used both to allow users to interact with the system and to communicate with remote components (Web Services) in order to fulfill a goal. We propose a symbolic model based approach to test orchestrators in the context of the systems they pilot. Our approach only takes as input a(More)
We propose a model-based black-box testing approach to test conformance of Web Service Compositions (WSC). When a WSC under test makes use of implementations of Web Services, two situations may occur: either communications between the WSC and the Web Services are observable or hidden internal actions. We show by means of an example how to generate test(More)
Model-based conformance testing of reactive systems consists in taking benefit from the model for mechanizing both test data generation and verdicts computation. On-line test case generation allows one to apply adaptive on-the-fly analyzes to generate the next inputs to be sent and to decide if observed outputs meet intended behaviors. On the other hand, in(More)
The omnipresence of complex distributed component-based systems offers numerous opportunities for malicious parties, especially thanks to the numerous communication mechanisms brought into play. This is particularly true for Smart Grids systems in which electricity networks and information technology are coupled to provide smarter and more efficient energy(More)
Remotely-communicating software-based systems are tightly present in modern industrial society and securing their complex architecture is recognized as crucial. In particular, the perspectives to reinforce their security by monitoring are promising. However, monitoring schemes still face challenges as the presence of untrusted components seems unavoidable.(More)

The IMS Learning Design specification aims at capturing the complete learning flow of courses, without being restricted to a particular pedagogical model. Such flow description for a course, called a Unit of Learning, must be able to be reproduced in different systems using a so called run-time environment. In the last few years there has been several tools(More)
