I am not really following your issue--you don't want to install and use the Python mock library?

[pgajdos]

Yes, this issue is meant this way: in case mock is not available, we could use built-in unittest.mock instead.

JFYI, I tried just mock -> unittest.mock (https://build.opensuse.org/package/view_file/home:pgajdos:python/python-napalm/python-napalm-no-mock.patch) and this works at least for 3.{8,9,10}.

I'm not opposed, feel free to open a PR and we shall review @pgajdos!

Yeah, I am not opposed to this either, but you would probably need to do the pull-request on it.

This is entirely a NAPALM development dependency so not sure why you care?
