摘要：In case of regression testing and prioritization approaches, specification level design and requirements concerns motivate changes in the source code. Traditional approaches are bottom up(or white box) and do not leverage on these concerns, so the new concept which considers these concerns is developed called as model based testing approach. Model-based testing approaches supports a top-down (or black box) testing approach, where design and requirements models are used in support of test generation. They enhance code-based approaches with the ability to test from a higherlevel design and requirements perspective. A model-based regression testing and prioritization approach is presented that efficiently selects test cases for regression testing based on different concerns. In particular we describe how to convert a UML diagram to xml file, how to derive the re-executable and reusable test cases and how to support concern- based regression testing and prioritize the re-executable test cases. Efforts have been initiated to map UML diagrams to XML documents, because Unified Modeling Language (UML) is a standard object oriented design modeling language for business and technical systems and Extensible Markup Language Schema (XML Schema) provide a means for defining the structure, content and semantics of XML documents and XML is widely being accepted as information representation and sharing language across Internet. In order to build a complete system, we have to map the static as well as the dynamic aspects of UML Diagrams. After this conversion, xml file is used to generate test cases which are reusable and re-executable. Re-executable test cases are further prioritized based on user concerns or dependency of re-executable test cases, which can be identified by activity diagram. This will minimize the efforts needed to validate new software versions and it will improve the overall productivity of the software development process.
