protected function assertHasPrimaryKey($table, $message = NULL) {

  }

  // The database layer doesn't support generic introspection into primary
  // keys. The simplest way to test whether a primary key exists is therefore
  // to try to create one and see whether that leads to an exception.
  try {
    $schema
      ->addPrimaryKey($table, []);
    $this
      ->assertTrue(FALSE, $message);
  } catch (SchemaObjectExistsException $e) {
    $this
      ->assertTrue(TRUE, $message);
  } catch (\Exception $e) {

    // Trying to create a primary key with an empty fields list will probably
    // still throw an exception, so we catch that as well.
    $this
      ->assertTrue(FALSE, $message);
