Hi Berker, 

Thanks for you response. 

I agree when you say that patch.dict is a simply operation, but I think that this test can be necessary, if for some reason the implementation of patch.dict (or its parts) decide change. 

> I think the relationship between dict and OrderedDict (including any other dict subclasses and dict-like objects) and anything related to insertion order should be tested either in test_dict or in test_ordered_dict.

I am not sure if this has to be tested on test_dict or test_oredered_dict, because we are not testing specifically dict-like objects.

This test, can be written on test_patch_dict and not create a new `test_patch_dict_with_orderdict`.
