Question

in order to test a managed class I tried to create an instance in a unit test by first trying to mock NSEntityDescription and NSManagedObjectContext.

id mockEntityDesc = [OCMockObject niceMockForClass:[NSEntityDescription class]];
id mockManagedObjectContext = [OCMockObject mockForClass:NSManagedObjectContext.class];

But before I can get any further I get the following error when test is run;

Undefined symbols for architecture i386:
“_OBJC_CLASS_$_NSEntityDescription”, referenced from:
objc-class-ref in CallsCoordinatorTests.o
“_OBJC_CLASS_$_NSManagedObjectContext”, referenced from:
objc-class-ref in CallsCoordinatorTests.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any advice please?
Thanks

Your unit test target is not linking with the Core Data framework.
