Automated Significant Load Testing for WS-BPEL Compositions

Web service compositions must provide services to hundreds even thousands of users concurrently. These applications must be load tested to ensure that they can function properly under high load. We propose in this paper a solution for load testing of WS-BPEL compositions. It is based on Timed Automata as model for specifying requirements to test under various load conditions, a distributed testing architecture, an algorithm for online load test generation and execution, and finally an automated log analysis technique. We also illustrate our approach by means of a case study.
