How can I change a connection string, or other app settings, at test time in Visual Studio 2008?

Question

I need to test a class library project in VS. This project, itself, does not have a web.config file, but the classes do on the web server to which it's deployed. I access these like this:

ConfigurationManager.ConnectionStrings["stringname"].ConnectionString;

Can I adjust these strings while running unit tests in VS? Should I have considered a different design method to avoid this problem?

Answer 1

You can put the configuration into the app.config of the unit test project.
