“…One of them is the lack of suitable tools, as they are too costly to use or do not answer either the tester's need or the required environment. Despite the fact that many works dealt with conformance testing of composed Web services [6], [5], [3], [4], no tools were proposed for particularly testing the conformance of a BPEL implementation with respect to its specification. Only the authors of [4] claim that they have developed a corresponding prototype tool that helps in the automation of their testing approach, but no information about its features and how it is used was provided.…”

WS-BPEL is considered as the emerging standard for Web service compositions. As more and more compositions are modeled using WS-BPEL, ensuring good quality of WS-BPEL codes becomes crucial. This paper shows a novel tool, WSCCT, implemented for conformance testing of WS-BPEL compositions. It is based on Timed Automata as model for online testing of WS-BPEL implementations. The tool is being extended with graphical user interfaces. Besides, we illustrate how to use our proposed tool for conformance testing of a travel agency scenario which is implemented in BPEL.

When user requirements alter in composite services, there is a need to change service composition or add and remove some services. Notwithstanding service level agreement, it is vital for service provider to assess quality properties. Computing execution duration process after any changes in service composition will be time consuming if it is completely performed ab initio. In this paper, a graph theory based approach is proposed, in which non-formal business process execution language is mapped into XBFG graph. then execution duration of primary composite service is computed and the results are stored. Using these results, execution duration of composite service can be computed after changing service composition in a less timely manner. General TermsPrediction of execution duration of composite service before change in service composition algorithm.

In a globalised networked economy, collaborative networks (CNs) are formed to take advantage of new business opportunities. Collaboration involves shared resources and capabilities, such as e-Services that can be dynamically composed to automate CN participants' business processes. Quality is essential for the success of business process automation. Current approaches mostly focus on quality of service (QoS)-based service selection and ranking algorithms, overlooking the process of service composition which requires interoperable, adaptable and secure e-Services to ensure seamless collaboration, data confidentiality and integrity. Lack of assessment of these quality attributes can result in e-Service composition failure. The quality of e-Service composition relies on the quality of each e-Service and on the quality of the composition process. Therefore, there is the need for a framework that addresses quality from both views: product and process. We propose a quality of e-Service composition (QoESC) framework for quality assessment of e-Service composition for CNs which comprises of a quality model for e-Service evaluation and guidelines for quality of e-Service composition process. We implemented a prototype considering a simplified telemedicine use case which involves a CN in e-Healthcare domain. To validate the proposed quality-driven framework, we analysed service composition reliability with and without using the proposed framework.
