An Approach to Testing Trustworthiness of Web Services

Based on the investigation of the uncertainty of Web services,an approach to web services testing is proposed.By introducing the threshold of trustworthiness,the approach has the anti-jamming ability against abnormal web services.And the approach can quantify the trustworthiness of candidate web services and the oracle and capability of each test case.Moreover,the approach can rank web services in terms of trustworthiness,which provides a criterion for users to select web services.In addition,the approach can not only test a simple service,but also composite web services.Finally,an experiment is designed and performed to prove the feasibility and effectiveness of the approach.
