It consists of combining and reusing existing Web services to best suit new user requirements. This paper proposes an UML profile to compose Web services based on their behavioral aspects. To do so, the web service WSDL files are first transformed to UML models;then the profile is used to integrate them;finally the MDA approach is adopted to transform the applied profile into a BPEL process. As such, our method has the advantages of being independent of the Web service composition language and the UML modeling tool. Finally, a case study is developed in order to show the benefits of our method.展开更多
In late 2001, the Object Management Group issued a Request for Proposal to develop a testing profile for UML 2.0. In June 2003, the work on the UML 2.0 Testing Profile was finally adopted by the OMG.

In June 2003, the work on the UML 2.0 Testing Profile was finally adopted by the OMG. Since March 2004, it has become an official standard of the OMG. The UML 2.0 Testing Profile provides support for UML based model-driven testing. This paper introduces a methodology on how to use the testing profile in order to modify and extend an existing UML design model for test issues. The application of the methodology will be explained by applying it to an existing UML Model for a Bluetooth device.展开更多
