How Do I Use the app.config file with a Test Project

I using unit testing, to ensure that I can read connect string info开发者_如何转开发rmation from the ConnectStrings section of my app.config file. This works fine in the application proper, However when I attempt to generate a unit test for this under the Test Project, the dll.config file is being ignored, and the connectstring info from the machine.config file is being retrieved instead. How do I ensure that my tests read from the correct config file?

Your test project must have its own App.Config file.

You should add an app.config file to to your test project and populate it with the necessary values. You may ask "Why can't I use the existing app.config in my project?" The real answer is probably out there but personally I like it this way because it means my test project never points at my production environment.
