""" This is a fork of the pymox library intended to work with Python 3. The file was modified by quermit@gmail.com and dawid.fatyga@gmail.com Previously, pyfakefs used just this file from the mox3 library. However, mox3 will soon be decommissioned, yet standard mock cannot be used because of the problem described in pyfakefs #182 and mock issue 250 (https://github.com/testing-cabal/mock/issues/250). Therefore just this file was forked from mox3 and incorporated into pyfakefs.
