AttributeError: module 'collections' has no attribute 'MutableMapping'

[pedro-acunha]

While executing the UnitTests.py file, the following error is given while using python 3.10:
AttributeError: module 'collections' has no attribute 'MutableMapping'

This is called due to a conflict in the new version of python where attribute MutableMapping is no longer in the module collections. It was moved to collections.abc.MutableMapping.

To work arround this issue, the compatibility.py file in ~/.local/lib/python3.10/site-packages/unittest2 should be edit as in here:

import collections 
if sys.version_info.major == 3 and sys.version_info.minor >= 10:
    from collections.abc import MutableMapping
else: 
    from collections import MutableMapping

Additionally, the class where "collections.MutableMapping" is called should be replace by "MutableMapping".
