随着软件开发规模的增大、复杂程度的增加, 软件测试变得越来越困难。自动化测试能够有效降低软件测试难度, 节约大量的人力、物力资源。根据软件自动化测试的概念和基本原理, 结合Silk Test测试工具和可扩展标记语言技术, 成功实现AutoCAD软件的自动化测试。实验使用了4Test程序语言编写自动化测试脚本，对AutoCAD软件进行了国际化测试与本地化测试, 通过运用元素和属性导航来查找信息的测试方法, 显著提高了结果比对的效率。依据最终良好的测试结果, 对软件自动化测试的必要性进行了分析。

With the increase of software development scale and complexity, software testing becomes more and more difficult. Automation testing can effectively reduce the difficulty of software testing and save lots of manpower and material resources. Based on the concept and principles of automation testing, aided with Silk Test testing tool and XML technology, AutoCAD software automation testing is successfully realized. The experiment adopts the 4Test programming language to write automated testing scripts. For AutoCAD software international and localization testing, the experiment uses the testing methods of finding information through elements and attributes navigation, which significantly improves the efficiency of compared results. Based on the final good testing results, the necessity of software test automation is analyzed.
