| 摘 要： | 为了减少变量变更的代价,需要评估变量在程序中的重要程度。对变量的重要性度量有利于合理安排软件测试资源,保证软件质量。通过分析程序中各变量状态,利用变量间的依赖关系构建变量依赖关系模型,将图论和变量重要性度量相结合。针对现有节点重要性度量方法存在的局限性问题,提出一种新的基于变量依赖关系模型的变量重要性度量方法。实验表明,该方法在变量重要性度量方面的准确性相比其他方法有所提升。

| Abstract: | In order to reduce the cost of variable change, it is necessary to evaluate the importance of variables in the program. The measure of the importance to the variables is beneficial to arrange the software test resources reasonably and ensure the software quality. In this paper, by analyzing the states of variables in the program, the model of variable dependency is constructed by using the dependency between variables, and the graph theory and the measure of variable importance are combined. Aiming at the limitations of the existing methods, a new method based on the variable dependency model is proposed. The experimental results show that the accuracy of this method is better than that of other methods. |
