Class

DatabaseTransactionTestCase

Test transaction support, particularly nesting.

Code

function testTransactionsNotSupported() {
  try {
    $connection = Database::getConnection();
    if (!$connection
      ->supportsTransactions()) {

      // Start a "required" transaction. This should fail if we do this
      // on a database that does not actually support transactions, and
      // the current database does claim to NOT support transactions.
      $txn = db_transaction(TRUE);
      $this
        ->fail('No transaction failure registered.');
    }
  } catch (TransactionsNotSupportedException $e) {
    $this
      ->pass('Exception thrown for unsupported transactions.');
  }
}
