UML based regression testing technique for oo software. (c2006)

Bibliography: leaves 50-51.In this thesis we present a technique for regression testing of object oriented software based on the unified modeling language (UML). UML is a widely accepted modeling language for object oriented software. Regression test selection is important because it saves both time and cost by reducing the number of test cases to be performed for validation. The technique presented in this thesis selects test cases from a pool of unit test cases as well as another pool of integration test cases. This test case selection technique is based on the design without access to source code. The UML design diagrams give us more insight of the interactions and dependencies than black box testing. Our approach utilizes two UML diagrams, the class and interaction overview. Class diagrams provide us with the blue print of the object oriented software including all the classes and methods. Interaction overview diagrams were newly introduced in UML2.0; however, their nature as a combination of interaction diagrams and activity diagrams makes them very useful in process modeling and test case selection.1 bound copy: vi, 51 leaves; ill.; 30 cm. available at RNL
