中文摘要：

按照测试用例自动生成技术的不同,将测试用例自动生成算法分为随机、遗传、蚁群、粒子群四类,对上述各类算法的现状和进展进行介绍、分析和探讨。最后,对软件测试用例自动生成的研究进行了总结。

英文摘要：

Based on the different techniques for the automatic test case generations,there were four categories,including random test algorithms,genetic algorithms,ant colony optimization algorithms,and particle swarm optimization algorithms.This paper introduced,analyzed,and discussed the status and overview of the four categories.Finally,it drew the conclusions for the automatic test case generation algorithms.
