    This class inherits from
    `astropy.cosmology.io.tests.base.ToFromTestMixinBase` because the cosmology
    comparison functions all have a kwarg ``format`` that allow the arguments to
    be converted to a |Cosmology| using the ``to_format`` architecture.

    This class will not be directly called by :mod:`pytest` since its name does
    not begin with ``Test``. To activate the contained tests this class must be
    inherited in a subclass.
