回归测试路径优先级模型

为了提高回归测试的效率，根据组件间的调用图，找出可能的路径片段，通过测试用例的执行历史进而计算出路径片段的覆盖指数，最后对覆盖指数进行排序，提出了一种测试用例的优先级模型.用此模型可以高效地进行回归测试，及时发现程序中的错误.
In order to improve the efficiency of regression testing, test case prioritization technology is particularly important. This paper is mainly to identify possible path segments by the call graph between components, to calculate path segments’ cover index by the execution history of test cases, and finally to put forward a priority model of test case based on the sort of the cover index.Through the research of this model, it can effectively carry out regression test, and detect the errors in the program timely
