中文摘要：

现有的影响分析算法大都基于程序的静态分析技术，分析方法比较复杂且精度不高．针对静态分析存在的问题，提出采用动态分析技术构造Java程序的动态调用图，基于动态调用图，采用k-类方法后向切片计算修改影响集合．实验表明该方法简便易行，分析精度高，便于修改影响分析技术在大型Java程序测试中的实际运用．

英文摘要：

The difficult problem of existing change impact analysis algorithm based on static analysis techniques is complicated and less accuracy. For this problem, a dynamic analysis technique is proposed to construct Java program call graph, by forward slices k-class method to affect sets. Experiments prove that this dynamic analysis technique is simple, convenient and higher accuracy for large scale Java programs tests.
