A weak mutation testing framework for WS-BPEL

Web Services Business Process Execution Language (WS-BPEL) is as an XML-based Web Services composition language for more complex business processes. Mutation Testing is error-based software testing in unit level which indicates efficiency of test suites. Weak mutation testing can reduce execution cost more than typical mutation testing. A few empirical studies identify its test effectiveness which was also closely to traditional mutation testing. Recently, there is a research which proposes definition of expression mutation operators for WS-BPEL, while the definitions are not completed for WS-BPEL language. Thereafter an investigation had presented more three mutation operators (Identifier replace operators, Activity operators, as well as Exceptional and event operators) which completely cover for WS-BPEL language. This paper provides a comprehensive analysis by using some mutation operators for WS-BPEL that can apply for weak mutation testing and also proposes a framework for generating mutants by using weak mutation technique. The framework can identify dead mutants and live mutants. Moreover the framework can present execution time, mutation score, and test cases effectiveness.
