中文摘要：

在．NET框架下，研究Web应用自动化测试工具，并给出了设计和实现。该自动化工具包含两个子工具WebTester和WebReplay。前者实现了对测试用例的自动录制、回放，而后者则允许测试人员手工编写测试脚本，进行更为复杂的测试。实现的关键是采用了两个开源的框架Watin和HTMLParser。

英文摘要：

The method of constructing a web application testing tool is proposed in this paper, which is based on .NET framework. The tool consists of two sub-automation tools, WebTester and WebReplay. The former one is for automatic recording and playback of a test case for the web application; while the latter one allows the tester to write manual test scripts for more complex web tests. Two open-source frameworks, Watin and HTMLParser, are essential for the implementation.
