  16      * 'db_type' : The name of the Doctrine DBAL database driver to use.
  17      * 'db_username' : The username to use for connecting.

  21      * 'db_port' : The port of the database to connect to.

  29      * 2) The database is dropped and recreated to ensure it's clean.
  30      *
  31      * @return Doctrine\DBAL\Connection The database connection instance.
