Abstract
We propose in this paper a new approach for conformance testing of WS-BPEL compositions under various load conditions. It is based on Timed Automata as model for testing WS-BPEL implementations, a distributed testing framework that automatically generates and executes parallel tests online, and an algorithm for online test generation and execution. We also implemented a part of our solution in the form of a prototype tool named WSCCT for WS-BPEL compositions conformance testing.
