I'm trying to add the Unit tests to my app but i not sure how to do it!

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

Answer 2

If I understand your question correctly, you're asking how to automate testing a WebForms UI. If I misunderstand, please correct this understanding.

Frankly, I don't think there is a good answer out there for this. There are two options, however, that work okay :

1. Visual Studio Test Edition
2. Telerik's Web Testing (both a free version and a version with a cost)
