Extenics-based test case generation for UML activity diagram

Abstract

Extenics is a new discipline for modeling contradiction problems with formalized methods and transformation. This paper for the first time combines software testing with Extenices and proposes an automatic approach to generating test cases from UML activity diagrams based on Extension Theory (Extenics). In order to find more defects in software system by minimized test cases, we design algorithm to construct the Euler circuit and generates test sequences automatically by Euler circuit algorithm. Our preliminary result shows that test cases generated not only satisfy the specified test coverage criteria but also the number of test cases is decreased. © 2013 The Authors.
