A product line based aspect-oriented generative unit testing approach to building quality components

The quality of component-based systems highly depends on how effectively testing is carried out. To achieve the maximal testing effectiveness, this paper presents a product line based aspect oriented approach to unit testing. The aspect product line facilitates the automatic creation of aspect test cases that deal with specific quality requirements. An expandable repository of reusable aspect test cases has been developed. A prototype tool is built to verify and lever up the approach.
