Abstract: Developing peer-to-peer (P2P) systems is hard because they must be deployed on a high number of nodes, which can be autonomous, refusing to answer to some requests or even unexpectedly leaving the system. Such volatility of nodes is a common behavior in P2P system and can be interpreted as fault during tests.In this paper, we propose a framework for testing P2P systems. This framework is based on the individual control of nodes, allowing test cases to precisely control the volatility of nodes during  execution.We validated this framework through implementation and experimentation on an open-source P2P system.
