Design and Implementation of a Framework for Testing BPEL Compositions

The Business Process Execution Language (BPEL) is emerging as the new standard in Web service composition. As more and more workflows are modeled using BPEL, unit-testing these compositions becomes increasingly important. However, little research has been done in this area and no frameworks comparable to the xUnit family are available. In this thesis, a layer-based approach to creating frameworks for repeatable, white-box BPEL unit testing is presented. Based on this approach, the concrete BPEL composition testing framework BPELUnit is developed. This framework uses a specialized BPEL-level testing language and literal XML data to describe interactions with a BPEL process to be carried out in a test case, and supports automated BPEL deployment/undeployment and test execution.
