Performance Testing of Composite Web-Service with Aspect-Based WS-BPEL Extension
Jong-Phil Kim · KSII Transactions on Internet and Information Systems · 2011
The advance in Service-Oriented Architecture (SOA) and web services has led to the development of new types of a system in which heterogeneous service components can connect and compose to solve a complex business problem.In the SOA, even though these service components are valid in their functionality, there is a need to test their behaviors when those services are composited.In recent years, WS-BPEL has received a wide acceptance as a means of integrating distributed service components.To test the composite service, the existing testing techniques have been focused on the functional features based on the WS-BPEL process.However as SOA approach is applying to real-time software development, the performance of composite service becomes one of important issues.This paper proposes a technique to the performance testing of a composite service with WS-BPEL extension which combined with the concept of aspect.Our WS-BPEL extension has been made towards annotating aspect component which is measuring the response time of the composite service.This paper also explains the procedure of performance testing with on-line transaction system.Our technique can apply to choose an adequate component in service composition with considering the performance among several candidate web service components.
