Generation and Prioritization of test sequences using UML activity diagram

Abstract

Software testing is one of the most important part in software development life cycle. Generation of test sequences which is essential for software testing is one of the challenging task. Testing can be done either manually or automatically. Automated testing is better than manual testing as it reduces cost as well as time. UML activity diagram are used to show the workflow of dynamic and behavioural aspects of the software system. Test sequences can be generated using the UML activity diagram and different prioritization techniques can be applied to select the effective paths. In this project, first we generate test sequences using the activity diagram. Then, we prioritize test sequences using Ant colony optimization. We have implemented the proposed algorithm. We have compared the proposed prioritization technique with the existing prioritization technique. Experimental results shows that our result is better than that of the existing technique.
