In recent years, agent-based systems have received considerable attention in both academics and industry. The agent-oriented paradigm can be considered a natural extension to the object-oriented (OO) paradigm. Agents differ from objects in many issues which require special modeling elements but have some similarities. Although there is a well-defined OO testing technique, agent-oriented development has neither a standard development process nor a standard testing technique. In this paper, we propose extensions of OO testing techniques to test agent oriented systems. For illustration purpose a multi agent air ticket booking system is implemented using JADE 3.5 and tested using our proposed method.
