Bluetooth Protocol Conformance And Interoperability Testing

Communication protocol testing is a hot research area. With the development of various protocol products, the importance of conformance test and interoperability test is realized by the industry world. As a promising new wireless protocol, Bluetooth is getting wide supports. But today's Bluetooth products have various interoperability problems, so the effective and thorough test is necessary. The test of communication software fells into the category of software testing, but has its own considerations.This paper presents a detailed survey on communication protocol testing and the standard OSI conformance test methods. In addition this paper presents an analysis on the trend of interoperability test which is paid more and more attention.This paper presents the test methods in the practical testing of Bluetooth protocol, and discusses the implementation of test control interface to make the test more automatically. And then the architecture and implementation technologies of Bluetooth tester are fully discussed.At last we make a discussion about the method to generate test sequences automatically from protocol formal description. We choose OBEX protocol which is designed with very complicated constraints in its PDUs as our research target. We describe it with our self-defined formal language based on Extended FSM from which all test sequences are generated automatically by our tool TCGen. And then we make a comparison between ad hoc test method and automatic test method.
