Regression Testing Based on UML Design Models

This paper presents a methodology for identifying changes and test case selection based on the UML designs of the system. Design artifacts used for this purpose are UML class diagram and sequence diagrams, which are used to generate an extended concurrent control flow graph (ECCFG) which is further used for regression testing, i.e., change identification and test case selection. A proof- of-concept tool has been developed and used on a case study, which shows that our approach selects a precise set of test cases from an existing test suite.
