Discrepancy in stub construction methods about sinon HOT 4 CLOSED

The default constructor would create a stub that overwrites the original object unknowing about how to restore it.
The stub would work, but a function like restore requires pre-knowledge of the original function behaviour, thus it won't be available.
The current implementation does not provide a restore function for the stubs created by the default constructor, thus the undefined value.

This was closed, but it looks like you wanted a new feature? Not a bug, but missing functionality? Could you describe how you wanted it to look?

This issue was mainly due to a confusion, if something would be updated may be it's the doc part.
Scenario:

• A stub function was being assigned to a stub object.
• After finishing the tests all the stubbed methods were being restored.

Issue:

• The restore() method is undefined for stubs that are created with the default constructor ( note: we can only stub using the default constructor in this case, as stub(obj, 'function') requires the 'function' to be predefined).

Fix:

• Check if the restore() is defined for the stubbed method before calling it.

Ah, I get you. There is no way to fix this, as a function in itself does not know which name it is assigned to, so a restore function would not know what to do with this.
