Tests for checking the actions system within Backdrop.

Class

ActionLoopTestCase

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

Code

protected function triggerActions() {
  $this->backdropGet('<front>', array('query' => array('trigger_actions_on_watchdog' => 'actions_loop_test_log')));
  $expected = array();
  $expected[] = 'Triggering action loop';
  $recursion_limit = config_get('system.core', 'action_recursion_limit');
  for ($i = 1; $i <= $recursion_limit; $i++) {
    $expected[] = "Test log #$i";
  }
  $expected[] = 'Stack overflow: recursion limit for actions_execute() has been reached. Stack is limited by %limit calls.';

  $result = db_query("SELECT message FROM {watchdog} WHERE type = 'actions_loop_test' OR type = 'actions' ORDER BY wid");
  foreach ($result as $row) {
    $expected_message = array_shift($expected);
    $this->assertEqual($row->message, $expected_message, t('Expected message %expected, got %message.', array('%expected' => $expected_message, '%message' => $row->message)));
  }
  $this->assertTrue(empty($expected), t('All expected messages found.'));
