Answer 1

You can add unit test to your UI using one of these tools

• http://watin.sourceforge.net/
• http://seleniumhq.org/

With both tools you can generate C# or VB classes that can be used by NUnit. IMHO, UI test are not as reliable as the common unit tests. Bacause timing conditions you may randomly find that some test will fail.

I used both tools and I recommend selenium mainly because you can generate test that can be run against any browser.

Here an example how to use Watin with NUnit http://www.codeproject.com/KB/applications/SimpleUITestHarness.aspx

And here a guide how to use Seleniun with Nunit http://www.lostechies.com/blogs/agilecruz/archive/2009/02/10/how-to-configure-selenium-rc-for-use-in-c-nunit-tests.aspx
