do not import unittest if mock is disabled

[lonepig]

I am working on an embedded Linux, whose python does not have unittest module supplied,
I moved the import statements, if use_mock is True, then do import

But do you need this lab module at all in an embedded environment? The proposal looks rather like a workaround, and I believe there may be a more proper way to provide the required functionality.

Does the minimal build work for you? If not, what's missing?

If you could share the requirements, I would either adjust the minimal build, or create a separate build for your requrements.

No, I do not need the lab module.
I use pyroute2 for DiagSocket, the first import pyroute2 would cause an import for unittest,
I guess importing IPRoute module can not be avoided, is there any other way can work without importing IPRoute?
I have tried the minimal build, the same thing happened.

    from pyroute2 import DiagSocket
  File "/home/root/pyroute2/__init__.py", line 16, in <module>
    from pyroute2.cli.console import Console
  File "/home/root/pyroute2/cli/console.py", line 7, in <module>
    from pyroute2.ndb.main import NDB
  File "/home/root/pyroute2/ndb/main.py", line 300, in <module>
    from .view import SourcesView, View
  File "/home/root/pyroute2/ndb/view.py", line 72, in <module>
    from .source import Source, SourceProxy
  File "/home/root/pyroute2/ndb/source.py", line 82, in <module>
    from pyroute2.iproute import IPRoute
  File "/home/root/pyroute2/iproute/__init__.py", line 133, in <module>
    from pyroute2.iproute.linux import RTNL_API, IPBatch
  File "/home/root/pyroute2/iproute/linux.py", line 13, in <module>
    from pyroute2.lab import LAB_API
  File "/home/root/pyroute2/lab.py", line 2, in <module>
    from unittest import mock
ModuleNotFoundError: No module named 'unittest'

Oke, let me see how to help in this situation. I believe this week we will fix it.

[svinota]

Sorry for delay, I'm fixing this tonight.

[svinota]

Merged the fix, please check if it works for you: #1100

When you confirm it working, I'll roll out a minor release for that.
