Self-adaptive Functional Testing of Services Working in Continuously Changing Contexts

Web Services and ad-hoc networks are examples for systems that work in continuously changing contexts. The services provided by such systems can be tested in a laboratory environment using the standard conformance testing methodology. Testing the inter-working of services with other services in all contexts is an impossible task, because the possible usages of services may not be known or may increase due to the development of new services. Thus, errors may occur and have to be detected and handled at runtime. Our approach to this problem is self-adaptive functional testing, which is a combination of monitoring and active testing at runtime. In order to locate an error which has been detected during monitoring, existing test cases are adapted automatically to the specific situation and applied afterwards at runtime.
