A Survey on Model Based Test Case Prioritization

Regression testing is the process of validating modifications introduced in a system during software maintenance. As the test suite size is very large, system retesting consumes large amount of time and computing resources. This issue of retesting of software systems can be handled using a good test case prioritization technique. A prioritization technique schedules the test cases for execution so that the test cases with higher priority executed before lower priority. The objective of test case prioritization is to detect fault as early as possible. Test case prioritization becomes a challenge in Component-based Software System (CBSS) which facilitates development of complex systems by integrating the reusable components. CBSS has emerged as an approach that offers rapid development of system using fewer resources and effort. The core idea of reuse and reducing the development costs can be achieved if the components offer reliable services. Thus, integration of components and testing become an important phase in CBSS. Integration of components involves understanding communication and coordination between the components. Developers do not provide the sufficient information on these components. As a result of this, understanding of component interactions while integrating these components becomes a challenge. Testing components is a challenging area of research. There have been troubles integrating the components. This in turn affects the quality and reliability of the software. Our research aims at analysing the existing test case prioritization techniques in code based, requirement based and model based prioritization techniques and it’ s implementation in CBSS . The systematic literature survey is based on nine articles collected from multiple-stage selection process. Keywords— Regression Testing, Test Case Prioritization, CBSS.
