With the gaining popularity, more and more SIP implementations have been developed and deployed. How to guarantee the conformance of those SIP implementations is the key point of interconnection and interoperation among them. This paper proposes the test method and architecture for the SIP protocol based on the IPv6 tester system. Tree and tabular combined notation (TTCN-2) is adopted to describe the test suite. With an enhanced reference implementation, the data-processing ability to the original test system has been greatly improved. In the following test practices, some errors have been found in the SIP entities under test. It is proved that the proposed test method and architecture are effective to verify the conformance of the SIP entities, and the result of the conformance test may provide helpful reference to the development of SIP products.展开更多

It is applicable to both nondeterministic and deterministic finite state machines. When applied to deterministic machines, this method yields usually smaller test suites with full fault coverage than the existing methods that also assure full fault coverage. In particular, the proposed mehod can be used to test the control portion of software specified in the formalspecification languages SDL or ESTELLE.展开更多
