The ``--reverse`` option can be used to sort test cases in the opposite order.
This may help in debugging tests that aren't properly isolated and have side
effects. :ref:`Grouping by test class <order-of-tests>` is preserved when using
this option.

 Fixed #23742 -- Added an option to reverse tests order.

This is useful for debugging side effects affecting tests that
are usually executed before a given test. Full suite and pair
tests sort cases more or less deterministically, thus some test
cross-dependencies are easier to reveal by reversing the order.
