An external web service may evolve without prior notification. In the course of the regression testing of a workflow-based web service, existing test case prioritization techniques may only verify the latest service composition using the not-yet-executed test cases, overlooking high-priority test cases that have already been applied to the service composition before the evolution. In this paper, we...
Cloud computing is an emerging computing paradigm. It aims to share data, calculations, and services transparently among users of a massive grid. Although the industry has started selling cloud-computing products, the software engineering infrastructure and application model are still unclear. In this paper, we compare cloud computing with service-oriented computing and pervasive computing. Both the...
Service orientation is an approach to developing software applications by means of service orchestration and choreography. In such applications, a service interacts with not only other services but also its embedding environment via contexts. However, it is still unclear about how to develop effective testing techniques for service orchestration and choreography, particularly in the presence of contexts...
Cloud computing is an emerging computing paradigm. It aims to share data, calculations, and services transparently among users of a massive grid. Although the industry has started selling cloud-computing products, research challenges in various areas, such as UI design, task decomposition, task distribution, and task coordination, are still unclear. Therefore, we study the methods to reason and model...
