asp.net - How to use web.config when unit testing an asp .net application

Question

I am starting out with unit testing, I have a method that uses the web.config for a connection string.

I was hoping to be able to use

[DeploymentItem("web.config")]

to get the web config file, this still leaves me with null reference exceptions (that'd be what I write my next test for).

How do I use the config file included with the project I am trying to test?

I am using the testing framework included in VS 2008, if that makes any difference.

Thanks

Unit test projects should have their own config file.

On a test project you can choose Add, New Item, Application Configuration File.

This file will behave exactly like a web.config, but then for your unit tests.
