Looks like a bug. doctest is failing to recognize that the decorated
function belongs to the module being tested.
A simple patch: In doctest.py, method _from_module, near line 840, you
have these lines:
elif inspect.getmodule(object) is not None:
return module is inspect.getmodule(object)
Move them up, just before the line:
This works fine in this case, but I'm not sure whether this breaks in
other circumstances (but I can't think of a case when using
inspect.getmodule() would not be appropiate).
PS: I can't see any tests for decorated functions (except
@classmethod/@staticmethod) in the library test suite. I'll try to add
some and submit a patch.
