The Testing Method for Interface Customized Component

Recently, Component Based Software Development is used to develop large and complicated software application systems based on available and reusable components. After selecting components, reusers usually need to modify components to meet the new requirements. Through customization, components can be reused in specific application environment or interact with other components. The interfaces are the only point for the interaction among components. Customization of black-box or on-line component is often done by modifying the interface. In this paper, an extended component interface specification model is proposed to support the component customization and testing. Based on the four kinds of interface specifications and the relationship between the specification elements, the customization operators, testing process and testing reuse principles are proposed. Finally, some experiments are carried and the results have shown that the customization mechanism and testing reuse principles can support the testing of interface customized components.
