How to add/open a bundle file in a test target

I have a static library that gets linked to by an application. The library code opens a file that is in bundle that is in the application bundle, the opening is done as: ``` NSString* plistPath = [[NSBundle mainBundle] pathForResource:@"Config" ofType:@"plist"]; ``` This is working fine. However I want to add some unit test code to the library, and so I have a logic test target for it. As the file is in the bundle for the application and not in the bundle for the static library I copied the `Config.plist` file and added it to the test code target via `Copy Bundle Resources`. However when I execute the test code the file cannot be found. Why is that? In that the above is confusing, here's a summary of the workspace structure. ``` Workspace contains: Application Project with application target, which contains (X) Config.plist (a) Library project which contains: Library target, which contains: the code opening the file in the bundle (b) Test library target, which contains: (Y) A Copy of the Config.plist (c) ``` So if I build X then when b runs it can find a. But when I build Y when it runs then b can't find c.
