How to do automated Webapplication testing using VS 2010

Currently I am doing automation testing of webapplications using nunit, wati开发者_StackOverflow社区n. How can I achieve same reults using VS 2010.

---

My current automated system test setup for a VS 2010 web app uses NUnit, the CassiniDev development server (http://cassinidev.codeplex.com/) and WatiN. I use ReSharper (plus dotCover) (http://www.jetbrains.com/resharper/ and http://www.jetbrains.com/dotcover/) to run/debug/cover the tests from within VS 2010.

In the NUnit test fixture setup I start the CassiniDev server pointing at the web app directory. WatiN is then able to test the site by hitting the development server.
