TDD - how is it done?

The next project will be done with Test Driven Development - i am really looking forward to this!

We have all read about TDD, on this pros and cons and how it is done (red, green, refactor or first write the test, fail it, fix it...). But i haven't seen to much on how to actual write the code. How do you start off? In other words - show me the code!

But this article has some hints and tips on how to write test driven code for business and ui-layers. Especially from the Doing Test-Driven Development paragraph. The rest of the article is a very nice introduction to Nunit and other tools.

I'll get back to you all when i have got the pieces together surrounding this.
