2. 9 core/modules/views/tests/src/Kernel/Handler/SortRandomTest.php \Drupal\Tests\views\Kernel\Handler\SortRandomTest::testRandomOrderingWithRenderCaching()

Tests random ordering with tags based caching.

The random sorting should opt out of caching by defining a max age of 0. At the same time, the row render caching still works.
