Remove tests.lib.path

File: https://github.com/pypa/pip/blob/master/tests/lib/path.py

There exist better alternatives to rolling out our own “Path” class for file handling – the stdlib pathlib.Path and pathlib2.Path (backport to Py2) should be more than sufficient to satisfy our needs now.

if sys.python_version_info[0] >= 3:
    from pathlib import Path
else:
    from pathlib2 import Path

To be done:

• Confirm that the pathlib equivalent is indeed enough for our needs.
  • Figure out the relevant workarounds if needed.
• Drop this file and just directly perform the imports.

Thank you @gutsytechster @ssurbhi560

Please see my comment here (specifically 2, 3, and 4) outlining the issues with switching, mostly due to the fact that the current tests.lib.path.Path inherits from str. We would want to address those issues in several PRs before switching to pathlib.Path/pathlib2.Path.

Once no tests fail, we’re all good.

Not true, we can have false negatives as mentioned in 4.

@ssurbhi560, don’t let this dissuade you! I would just be very thoughtful and submit small PRs that get us closer to being able to make the switch. 😃
