• Triages PseudoNetCDF tests failing randomly #3711

FYI you'll get an upstream-dev failure due to some ongoing work in cftime: Unidata/cftime#158 (comment). You can temporarily remove it from the build if you'd like, but hopefully it will be resolved soon.

Cheers @spencerkclark . Do you know which tests we should xfail? We can do it ex-post if you're not sure.

I think we should really try and keep the build passing, partly as contributor-friendliness, partly as signalling, partly as internalizing the externalities of flaky tests

[spencerkclark]

Absolutely; it's this one:

xarray/xarray/tests/test_cftime_offsets.py

Lines 1179 to 1184 in c707b33

	@pytest.mark.parametrize("freq", ["A", "M", "D"])
	def test_dayofyear_after_cftime_range(freq):
	pytest.importorskip("cftime", minversion="1.0.2.1")
	result = cftime_range("2000-02-01", periods=3, freq=freq).dayofyear
	expected = pd.date_range("2000-02-01", periods=3, freq=freq).dayofyear
	np.testing.assert_array_equal(result, expected)

Feel free to add an xfail here.
