Abstract

Software development under the cloud computing model brings the advantage that new applications can be rapidly constructed by tailoring existing services. However, the use of Internet-based services as software components, leads to the development of applications in which some building blocks are hosted remotely, rather than locally in a controlled environment. This aspect of cloud-based development, when coupled with factors such as service autonomy, complexity, and high dependability criteria, make software testing of the cloud especially challenging. In this paper we present a novel approach to support integration testing of applications that depend on remotely-hosted cloud services. Our approach seeks to reuse elements of the test automation, typically built to validate a cloud service prior to its deployment, for the realization of Test Support-as-a-Service (TSaaS). TSaaS provides developers with a set of functions that enable integration testing of cloud services using controlled virtual environments. To facilitate continued evaluation of our approach, we have implemented a prototype of TSaaS that is compatible with the Windows Azure platform.
