Class

ActionLoopTestCase

Test actions executing in a potential loop, and make sure they abort properly.

Code

        $expected[] = "Test log #{$i}";
    }
    $expected[] = 'Stack overflow: too many calls to actions_do(). Aborting to prevent infinite recursion.';
    $result = db_query("SELECT message FROM {watchdog} WHERE type = 'actions_loop_test' OR type = 'actions' ORDER BY wid");
