Web services are extensively used nowadays as a typically application programming interfaces for Business-to-Business process collaboration and BPEL (Business Process Execution Language) is an emerging standard language to orchestrating multiple web services. BPEL also offers advanced features such as concurrency and hierarchy which provides different programming construct from traditional sequential program. There are studies to propose Unit test framework and test cases generation; however, there is lack of studies in evaluating the testing criteria against BPEL. To address this issue, an empirical study is conducted to evaluate some test criteria derived from traditional sequential program testing.
