T2484: Move sharable fixtures out of conftest into a dedicated pytest plugin
Commits
rDSTO23318c21d101: setup: Do no expose the pytest-plugin any longer
Summary

Defining the pytest-plugin though the pytest-plugin [1] makes it loaded by default.
This creates loading issues on modules depending on storage but not on
the pytest plugin storage exposes. It was explained in the doc and I did not realize [2]

Instead we'll explicitely define to modules depending on the pytest plugins in
their root conftest [3]:

pytest_plugins = [ "swh.storage.pytest_plugin" ]

The following fix remains with the current other modules [4] by:

  • adding their deps as swh.storage[testing] if not already.
  • drop the eventual duplication introduced in tox.ini for the now apparent wrong reasons ;)
  • remove the workaround to avoid loading stuff from storage where not needed (swh-web for one)

[3] https://docs.pytest.org/en/stable/writing_plugins.html#requiring-loading-plugins-in-a-test-module-or-conftest-file

[4] as an example of adaptations D3479 (mercurial loader)

The documentation should read pytest_plugins = ["swh.storage.pytest_plugin"]. You also need to add that line to your own conftest.py if you're depending on that fixture.

You also need to add that line to your own conftest.py if you're depending on that fixture.

I did not since we import * from the conftest.
But yeah, i guess that'd make sense we eat our own cake ;)

I'll adapt my typos in description and commit message.
Thanks ;)

Adapt according to remarks:

  • Update docstring
  • use the pytest_fixtures definition ourselves
