Business Process Regression Testing

摘要

Business Process Execution Language (BPEL) has been recognized as a standard for the service orchestration in Service Oriented Architecture (SOA). Due to the pivotal role played by BPEL in service composition, the reliability of a business process becomes critical for a SOA system, especially during its evolution. Regression testing is well known as an effective technology to ensure the quality of modified programs. To reduce the cost of regression testing, a subset of test cases is selected to (re)run, known as regression test selection. Previous work addressing this problem will fail in the presence of concurrent control flow, which is an important and widely used feature of BPEL in describing service orchestration. In this paper, a regression testing approach for BPEL business processes is presented. In this approach, an impact analysis rule is proposed to identify the test paths affected by the change of BPEL concurrent control structures. Based on the impact analysis result and process changes identification, the impacted test paths are classified into reusable, modified, obsolete and new-structural paths. Experiments show that our approach is feasible.
