1690019325,PR_kwDOAMm_X85PddJ6,7799,Start making unit testing more general,6197628,closed,0,,,7,2023-04-30T18:04:52Z,2024-01-11T11:49:14Z,2024-01-11T11:49:14Z,CONTRIBUTOR,,0,pydata/xarray/pulls/7799,"As part of https://github.com/pydata/xarray/issues/525, I would like to start running the same tests already implemented for `pint` on other unit libraries - the one I'm specifically interested in is `astropy`.

This PR is a proof of concept to start making the tests in `test_units.py` more general, so it's easy to implement tests against other unit libraries. Important bits of this PR:

- The `UnitInfo` base class, which defines an interface against which additional unit libraries can be implemented.
- Concrete implementations of this for `pint` and `astropy` (the astropy one is commented out for now)
- Modifications that make `test_apply_ufunc_dataarray` run for both `astropy` and `pint`.
- A few new tests for helper functions, that I needed to fix issues with `astropy` testing

Would be greatful for feedback - is this worthwhile? If so, I can roll this approach out to more tests in `test_units.py` (there's certainly a lot of them!), either in this PR or a subsequent one.","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/7799/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,,13221727,pull
