Automatic generation of test-beds for pre-deployment QoS evaluation of Web services

This paper presents Puppet (Pick UP Performance Evaluation Testbed),an approach for the automatic generation of test-beds to empirically evaluate different QoS features of a Web Service under development. Specifically, the generation exploits the information about the coordinating scenario, the service description and the specification of the agreements that the roles will abide. The approach is supported by a proof-of-concept tool to validate the feasibility of the idea.
