进行NUnit测试我的网站。 [英] Conducting NUnit Test For my website.
本文介绍了进行NUnit测试我的网站。的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我是单元测试的新手;如果有人可以指导我的数据库驱动的网站进行单元测试会很有帮助。
这个网站的工作是将数据从excel上传/传输到数据库并显示记录在网格视图中。如果用户想要进行一些更改，例如编辑/删除数据，他/她将能够通过GridView完成。
我想使用NUnit，为我的网页进行单元测试。
我也附上代码供参考。如果有人可以在这个问题上帮助我，那将非常有帮助。
提前致谢。

-------------
I am new to unit testing; it would be helpful if anybody can guide to conduct unit testing for my database driven website.
This website’s job is to upload/transfer data from excel to database and display records in the Grid View. If user wants to make some changes e.g. Edit/Delete to the data, he/she will be able to do it through GridView.
I want to use NUnit, for conducting unit test for my web page.
I am also attaching the code for reference. If anybody can help me in this issue it would be really helpful.
Thanks in advance.
