Add pending tests

pending function ignores the block passed (Issue #16).


You didn't add this file to the project file, so it doesn't run as-is. That's fine, though--I'd rather see a pending included in `FunctionalTests+ObjC.m`, rather than creating an entirely new file.

So I would get rid of this file and just add a pending somewhere in `FunctionalTests+ObjC.m`.
