I have on idea what's going on here but maybe somebody who knows Windows better has a guess:

``` ================================== FAILURES =================================== __ TestEncodeCFVariable.testmissing_fillvalue ___ self = <xarray.test.test_conventions.TestEncodeCFVariable testMethod=test_missing_fillvalue> def test_missing_fillvalue(self): v = Variable(['x'], np.array([np.nan, 1, 2, 3])) v.encoding = {'dtype': 'int16'} with self.assertWarns('floating point data as an integer'):

      conventions.encode_cf_variable(v)

xarray\test\test_conventions.py:523:

C:\Python27-conda32\lib\contextlib.py:24: in exit self.gen.next()

self = <xarray.test.test_conventions.TestEncodeCFVariable testMethod=test_missing_fillvalue> message = 'floating point data as an integer' @contextmanager def assertWarns(self, message): with warnings.catch_warnings(record=True) as w: warnings.filterwarnings('always', message) yield assert len(w) > 0

      assert all(message in str(wi.message) for wi in w)

E AssertionError: NameError: all(<generator object \<genexpr> at 0x0617D170>) << global name 'message' is not defined xarray\test__init__.py:140: AssertionError ============== 1 failed, 970 passed, 67 skipped in 70.58 seconds ============== ```

I could understand a warning failing to be raised, but the NameError is especially strange.
