We actually get the failure in the call to `.broadcast_like()` itself, i.e. not in the assertion about the result:

```python
___________________________________________ TestDataArray.test_broadcast_like ____________________________________________

self = <xarray.tests.test_dataarray.TestDataArray object at 0x7f2287e3a828>

    def test_broadcast_like(self):
        arr1 = DataArray(np.ones((2, 3)), dims=['x', 'y'],
                         coords={'x': ['a', 'b'], 'y': ['a', 'b', 'c']})
        arr2 = DataArray(np.ones((3, 2)), dims=['x', 'y'],
                         coords={'x': ['a', 'b', 'c'], 'y': ['a', 'b']})
        orig1, orig2 = broadcast(arr1, arr2)
>       new1 = arr2.broadcast_like(arr1)
