Intersting, we are working on this:
https://github.com/oVirt/vdsm/blob/master/tests/storagefakelib.py
But it fakes vdsm module, not the underlying lvm commands.

It's actually a small class which mimics teh LVM behavior.
It was written from scratch - and is still rough. But the idea works out.
It is intended to be used with python-mock.
The module is here:
https://gerrit.ovirt.org/gitweb?p=imgbased.git;a=blob;f=tests/fakelvm.py;hb=HEAD
One consumer of this is:
https://gerrit.ovirt.org/gitweb?p=imgbased.git;a=blob;f=tests/testSanity.py;hb=HEAD
The biggest gap is to document it and get the API straight.
I.e. currently I tried to follow the following pattern:
lv = LV() # To instantiate a LV
lv = VG().create(…) # To create a mocked VG
