Abstract

Automatic test data generation for path coverage is an undecidable problem and genetic algorithm (GA) has been used as one good solution. This paper presents a method for optimizing GA efficiency by identifying the most critical path clusters in a program under test. We do this by using the static program analysis to find all the paths having the path conditions with low probability in generating coverage data, then basing on these path conditions to adjust the procedure of generating new populations in GA. The proposed approach is also applied some program under tests. Experimental results show that improved GA which can generate suitable test data has higher path coverage than the traditional GA.
一种利用遗传算法生成测试数据的技术
路径覆盖测试数据的自动生成是一个不确定问题,遗传算法是一个很好的解决方案。本文提出了一种通过识别被测程序中最关键路径簇来优化遗传算法效率的方法。通过静态程序分析,找出所有在生成覆盖数据时具有低概率路径条件的路径,然后根据这些路径条件调整遗传算法生成新种群的过程。该方法已在某程序的测试中得到应用。实验结果表明,改进遗传算法比传统遗传算法具有更高的路径覆盖率,能够生成合适的测试数据。
