Conformance testing for quality assurance of clustering architectures

Given the scalability of load balancing based architectures, it is increasingly necessary to develop appropriate quality assurance methodologies and techniques, of which Testing is widely adopted and used one. This paper describes a distributed platform for checking the conformance between real functioning of a given load balancer and its specified requirements. Our solution is based on Timed Automata as model for testing supported load balancing algorithms. This paper also shows a novel prototype tool support, LBACT, implemented for quality assurance of load balancing based architectures. Finally, we illustrate our contribution in the context of BPEL clustering mechanisms.
