However, I thought the test should rather go into [test_dataarray.py](https://github.com/pydata/xarray/blob/master/xarray/tests/test_dataarray.py) than [test_missing.py](https://github.com/pydata/xarray/blob/master/xarray/tests/test_missing.py), because
this is an improvement to resample/_upsample?

Something like
```python
    def test_upsample_tolerance(self):
        # Test tolerance keyword for upsample methods bfill, pad, nearest
        times = pd.date_range('2000-01-01', freq='1D', periods=2)
        times_upsampled = pd.date_range('2000-01-01', freq='6H', periods=5)
        array = DataArray(np.arange(2), [('time', times)])

        # Forward fill
        actual = array.resample(time='6H').ffill(tolerance='12H')
        expected = DataArray([0., 0., 0., np.nan, 1.],
                             [('time', times_upsampled)])
        assert_identical(expected, actual)
