Software Testing and Maintenance is the crucial phase of software development life cycle (SDLC). More than half of the total development cost of a software system is associated with this phase. As the size and complexity of software get increases testing of software also becomes complex and takes more time and cost. Therefore it is required to detect faults as earlier as possible to maintain the software quality. Test cases or scenario prioritization is one of the effective techniques to find error earlier. In this paper, we proposed a combined approach to generate and prioritize test cases using UML Sequence and Activity diagrams. The objective of the project is effective use of UML model for test case prioritization with high fault detection rate and higher testing coverage criteria to reduce time and cost of software testing.
