- name: Run xarray zarr backend tests
# xarray keeps its backend tests in the `xarray/tests/backends` package
# (pydata/xarray#11633 split the former `test_backends*.py` modules into
# it). Running the package covers the zarr store, region/append, API and
# DataTree tests; the other backends are installed by the `io` extra, so
# their tests run too, as they did before the split.

Run the downstream xarray CI job against the `xarray/tests/backends` package, where pydata/xarray#11633 moved the backend tests; the job had been failing to collect any tests.
