Research on Loop Path Selection in Coverage Testing

The traditional strategies of loop path selection like Z-path strategy will simplify the structure of loops and limit the iteration of loops to make the process of paths easy. But these strategies will lead to imprecise problems and hamper further improvement of the coverage scope, because the incompletely unfolding of loops usually ignores many detailed paths. To solve above problems, this paper claims a new path selection method based on loop processing model. In this method, an integrity path (contains loops) will be generated by static analysis and dynamic execution of the test code. And the new method can help expand the coverage area and increase the level of integrity path accuracy as well.
