A Systematic State-Based Approach to Regression Testing of Component Software

Abstract

Today, component-based software engineering has been widely used in software construction to reduce project cost and speed up software development cycle. Due to software changes in new release or update of components, regression testing is needed to assure system quality. When changes made to a component, the component could be affected, moreover, the changes could bring impacts on the entire system. We firstly identify diverse changes made to components and system based on models, then perform change impact analysis, and finally refresh regression test suite using a state-based testing practice. Related existing research did not address the issue of systematic regression testing of component-based software, especially at system level. The paper also reports a case study based on a realistic component-based software system using a, which shows that the approach is feasible and effective.
