Web Services Composition Testing: A Strategy Based on Structural Testing of Parallel Programs

Web Services have been used in the development of loosely coupled applications. Several Web Services are usually combined to create new services by a mechanism named Web Services Composition. In this paper, we present a strategy for Web Services Composition structural integration testing. Structural testing coverage criteria for services written in BPEL are also described. The concept of required element groups is defined to improve the accuracy of criteria coverage. We present a case study for assessing the applicability of proposed strategy. ValiBPEL-Web, a tool that supports the test strategy is also presented.
