    Parameters
    ----------
    a : xarray.Dataset, xarray.DataArray or xarray.Variable
        The first object to compare.
    b : xarray.Dataset, xarray.DataArray or xarray.Variable

    rtol : float, optional
        Relative tolerance.
    atol : float, optional
        Absolute tolerance.
    decode_bytes : bool, optional
        Whether byte dtypes should be decoded to strings as UTF-8 or not.
        This is useful for testing serialization methods on Python 3 that
        return saved strings as bytes.
