Base class not finding app settings

This is somewhat of a general question but I haven't found much by googling it. I have a test framework that sets up an environment for testing purposes. My application consumes this framework through a reference path and runs manual tests just fine. However, once I ask the build server to run my test the framework complains it cannot find any of my app settings. The app.config file sits in my testing project for my application and I am sure it exists in the correct bin folder on my build server. I'm doing this in a C# .NET environment.
