A FRAMEWORK TO MAGNITUDE THE PERFORMANCE AND BEHAVIOR OF WEB SERVICES USING ONTOLOGY

A web service is a software interface that describes a collection of operations that can be accessed over the network through standardized XML messaging. Web services in different domains are diverse in implementation techniques thus requiring us to meet a wide range of test requirements. Testing services and service centric system poses new challenges to testing approaches. Several web services testing were developed to address these new challenges. Without testing, the web service is likely to suffer from various issues in terms of speed, scalability and stability. In this study, a generalized ontology model is used to measure the non-functional testable parameters and find the dependencies between them. The web services are got from the service providers and various testing is being executed over these services. Web service testing is performed to ensure that their functionality is in accordance with the Service Level Agreement (SLA). Metrics for each dependency will be formulated and invoked during every test and thus the test results which contain all the results about each service will be generated using Web Application Performance Tool (WAPT).
