Integrating white- and black-box techniques for class-level regression testing

In recent years, several techniques have been proposed for class-level regression testing. Most of these techniques focus either on white- or black-box testing, although an integrated approach can have several benefits. As similar tasks have to be carried out for both white- and black-box testing, an integrated approach can improve efficiency and cost effectiveness. The article explains an approach for class-level regression testing, integrating existing techniques. Particularly, those of Rothermel et al. (2000) and Hong et al. (1995) for white-box regression testing and black-box testing, respectively, have been integrated into a single technique. The benefits of the resulting technique are shown by example
