Model-Based Generation of Testbeds for Web Services

Abstract. A Web Service is commonly not an independent software entity, but plays a role in some business process. Hence, it depends on the services provided by external Web Services, to provide its own service. While developing and testing a Web Service, such external services are not always available, or their usage comes along with unwanted side effects like, e.g., utilization fees or database modifications. We present a model-based approach to generate stubs for Web Services which respect both an extra-functional contract expressed via a Service Level Agreement (SLA), and a functional contract modeled via a state machine. These stubs allow a developer to set up a testbed over the target platform, in which the extra-functional and functional behavior of a Web Service under development can be tested before its publication.
