Using Core Data with OCUnit

Hey all,

I'm having a bit of trouble getting my Core Data NSManagedObjectModel to load from within my unit tests. The code I'm using to load the model (and context) is in my application code, not in my unit test; but I do call it from my test class's setUp() method.

	The strange part is that when I load my object model:

_mom = [[NSManagedObjectModel mergedModelFromBundles: nil] retain];

This works just fine when I run my application, but when I run my test cases, it returns an empty object model. A simple NSLog following that initialization results in:

2008-03-10 02:34:19.854 otest[2063:80f] Model initialized: (<NSManagedObjectModel: 0x136340>) isEditable 1, entities {
}, fetch request templates {
}


I've copied my xcdatamodel file to the Compile Sources section of my OCUnit target, and the compiled .mom file appears in the same place in the resulting bundle as it does in the application bundle. Further, it is the same file.

	I'm at a loss for how to proceed in debugging this problem.  Any ideas?

Thanks,

Wil
