There are two zarr issues that are causing some tests to fail:

  1. zarr can't store zero-dimensional arrays. python za = zarr.create(shape=(), store='tmp_file') za[...] = 0 raises a file permission error. I believe that this is alimanfoo/zarr#150.
  2. lots of the things that xarray likes to put in attributes are not serializable by zarr python za = zarr.create(shape=(1), store='tmp_file') za.attrs['foo'] = np.float32(0) raises TypeError: Object of type 'float32' is not JSON serializable. This is alimanfoo/zarr#156.

Most of the failures of tests inherited from CFEncodedDataTest can be attributed to one of these two issues.
