conftest.py

"""Conftest.py (root-level).

We keep this in root pytest fixtures in pytest's doctest plugin to be available, as well
as avoiding conftest.py from being included in the wheel, in addition to pytest_plugin
for pytester only being available via the root directory.

See "pytest_plugins in non-top-level conftest files" in
https://docs.pytest.org/en/stable/deprecations.html
