WSCLT: A Tool for WS-BPEL Compositions Load Testing

This paper addresses the load testing of WS-BPEL compositions. For that, we developed WSCLT tool, which takes as input a specification of the composition under test, expressed as a Timed Automaton, and considers various parameters such as the number of requests to handle simultaneously. Our WSCLT tool injects this load in the application and monitors the sequence of requests, invocations and responses between the components. This log is then analyzed by the tool to separate the actions corresponding to each instance and to check that they follow legitimate paths. A global report is then issued regarding all concurrent instances. We illustrate how to use our prototype tool by means of a case study.
