xarray.testing.assert_identical

xarray.testing.assert_identical(a, b, from_root=True)

Like xarray.testing.assert_equal(), but also matches the objects’ names and attributes.

Raises an AssertionError if two objects are not identical.

For DataTree objects, assert_identical is mapped over all Datasets on each node, with the DataTrees being identical if both are isomorphic and the corresponding Datasets at each node are themselves identical.

Parameters:

• a (xarray.Dataset, xarray.DataArray, xarray.Variable or xarray.Coordinates) – The first object to compare.

• b (xarray.Dataset, xarray.DataArray, xarray.Variable or xarray.Coordinates) – The second object to compare.

• from_root (bool, optional, default is True) – Only used when comparing DataTree objects. Indicates whether or not to first traverse to the root of the trees before checking for isomorphism. If a & b have no parents then this has no effect.
