An automated approach to robustness testing of BPEL orchestrations

Service compositions are increasingly used for the fast development of loosely-coupled dynamic distributed applications. Such compositions are prone to potential failures arising from their complex interaction scheme and from various kinds of network problems. Functional testing could overlook such failures, hence we claim it is important to specifically consider test cases for validating how the composite service reacts when invalid or unexpected events occur. We have developed the TASSA framework for automated generation and execution of robustness test cases. The framework addresses BPEL orchestrations and relies on fault-injection mechanisms. In the paper we motivate BPEL robustness testing, introduce the framework and present its preliminary assessment on a case study.
