Business process analysis is one of the major concerns for companies: before processes are enacted and executed, flaws and bottlenecks should be removed. Process simulation has been traditionally used to simulate process paths based on stochastic information. However, the obtained results are often not consistent with the behavior that can be observed later during process execution as the functioning and reaction of the orchestrated web services cannot be considered. To provide more realistic results, a process testing environment is presented that equips the Cloud Process Execution Engine (CPEE) with a newly developed logging component. The contribution of the logging component is that it incorporates simulated data from invoked services and thus allows for the generation of more realistic log files.
