Web Service Conformance Testing And Log Analyzing

With the developing of Internet, Web Services have more attention because of the character of platform independent and loose coupling. The composition of Web Services developed by different participants can achieve more complicated business. Choreography describe the interaction of Web Services composition in a global view. How to test the conformance of the Choreography and developed Web Services is very meaningful.Our research group put forward the framework of comformance testing based on the Choreography Scenario, but have some problems to be improved:(1) The XML Schema type refinement need to be optimized.(2) The framework of comformance testing need to be improved to test Web Services composition.(3) Add the model that the integration and analyzation of log in the distributed environment.This paper propose the improved methods and solutions based on the problem, include:(1) Improve the algrithoms of type refinement, solve the the composition of indicators and guard information, raise the rate of cover and reduce the invalid data.(2) Relize and design the conformance testing framework, include: the front tier、middle tier and target system tier. The front tier is user interface. The middle tier has the monitor module, test data generation module and projection module. Target system tier has the proxy module and stub module.(3) Achieve the conformance testing of single Web Service based on the projection. Choreography describe the interaction of the Web Services composition in a global view. Projection mapping the global interation to the role make the conformance testing of single Web Service available.(4) Achieve the conformance testing of composition of Web Services based on the integration and analyzation of log. Proxy and stub collect the log information, the integration of log describle the global specification. The integration of log and scenario make the conformance testing of composition of Web Services available.(5) Do the experiment and develop the testing tool. Import the information of scenario, tested services, the strength and path of test data generation. Export the result of conformace testing.
