 #. At the top of the table, select the desired action: :guilabel:`Play`, :guilabel:`Pause`, or :guilabel:`Delete`.
    If the entire bulk action succeeds, the :guilabel:`Test state` column displays the new state of each of the affected tests. If any part of the bulk action fails, the entire bulk action is canceled and none of the tests are updated. For example, if the bulk action was to delete 400 tests and one deletion fails, none of the tests are deleted.
