Abstract: Web services are the W3C-endorsed realization of service-oriented architecture (SOA). Since Web services are tested in black-box via their interfaces, how to automatically generate effective test suites has become a key problem in Web services automatic testing. However, the existing tools take insufficient account of WSDL (Web services description language) schema structure and the dependency between data elements, and lack of effective means of test automation, which may lead to high cost and test data can‘’t cover the test requirements. This paper proposes a test case generate framework and implements a tool which supports the above framework. At first, this framework acquires SOAP (simple object access protocol) skeletons which cover structural characteristics based on WSDL, then generates SOAP envelopes based on variable strength combinatorial testing model, finally generates operation sequence test path through the finite state machine/interface contract model. The experimental results show that the proposed framework can enable the test to achieve the desired coverage, while enhancing the fault detection ability and optimality on the size of existing approach.
