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

Question

I using unit testing, to ensure that I can read connect string information 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?

Answer 1

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

Answer 2

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.
