—As the technologies of autonomic computing become more prevalent, it is essential to develop methodologies for testing their dynamic self-management operations. Self-management features in autonomic systems induce structural and behavioral changes to the system during its execution, which need to be validated to avoid costly system failures. The high level of automation in autonomic systems also means that human errors such as incorrect goal specification could yield potentially disastrous effects on the components being managed; further emphasizing the need for runtime testing. In this paper we propose a self-testing framework for autonomic computing systems to dynamically validate change requests. Our framework extends the current architecture of autonomic systems to include self-testing as an implicit characteristic, regardless of the self-management features being implemented. We validate our framework by creating a prototype of an autonomic system that incorporates the ability to self-test.
