In order to avoid the problem that the data of the trustworthiness metrics of Web services would be hard to collect,this paper put forward the TWSMM-SD by using the number and types of defects to measure the trustworthiness of Web services indirectly.In the TWSMM-SD,the defects in the Web services would be firstly collected and sorted,and secondly the extent of each kind of defects to the final trustworthy degree would be defined by the defect evolvement and would be integrated as weight of the kind of defects,and finally the final trustworthy degree would be obtained by HMM.It tested a Web service by the test platform of Software Testing Center in Chongqing to get its number and types and measured by TWSMM-SD.The results show that this method can be effective and available in trustworthiness metrics of Web services.
