Class

DatabaseNextIdCase

Check the sequences API.

Code

function testDbNextId() {
  $first = db_next_id();
  $second = db_next_id();

  // We can test for exact increase in here because we know there is no
  // other process operating on these tables -- normally we could only
  // expect $second > $first.
  $this
    ->assertEqual($first + 1, $second, t('The second call from a sequence provides a number increased by one.'));
  $result = db_next_id(1000);
  $this
    ->assertEqual($result, 1001, t('Sequence provides a larger number than the existing ID.'));
}
