網際服務(Web Services)主要的目的是提供一個系統整合的標準，將不同平台的軟體元件包裝成網際服務，並藉由服務導向軟體架構(Service Oriented Architecture)的概念，提供更高彈性、更高效率、及資訊整合的IT環境。雖然元件的重複利用增加了系統整合的效率，但在網際服務提昇整合效率的同時，網際服務品質的重要性亦愈來愈受到重視，就如同其他的軟體一樣，網際服務亦必需被嚴謹地測試，以確保其品質與可靠性。本論文提出一個支援網際服務組裝之測試的架構，並透過設計和實作此架構，發展出一個具有自動產生測試案例及網際服務客戶端的網際服務測試自動化工具，以實際執行測試案例來驗證網際服務執行的正確性。

The main purpose of Web Services is to offer a standard of system integration. By means of the concept of Service-Oriented Architecture, software components from different platforms were wrapped into Web Services to offer higher flexibility, high efficiency, and IT environment providing integrated information. While the reuse of software component promotes the efficiency of system integration, we also pay attention to the quality of Web Services. Like other traditional software, Web Services also require to be tested thoroughly in order to ensure their quality and reliability. In this paper, we propose a framework to support testing on Web Services composition. Through designing and implementing this framework, we developed a testing tool for Web Services testing. Test cases are generated and exercised to show the effectiveness of the tool for verifying the correctness of Web Services.
