2009-05-30 15:33:06 +04:00
* 'db_type' : The name of the Doctrine DBAL database driver to use.
* 'db_username' : The username to use for connecting.
* 'db_password' : The password to use for connecting.
* 'db_host' : The hostname of the database to connect to.
* 'db_name' : The name of the database to connect to.
* 'db_port' : The port of the database to connect to.
*
2009-05-30 15:33:06 +04:00
* Usually these variables of the $GLOBALS array are filled by PHPUnit based
* on an XML configuration file. If no such parameters exist, an SQLite
* in-memory database is used.
*
2009-05-30 15:33:06 +04:00
* IMPORTANT:
* 1) Each invocation of this method returns a NEW database connection.
* 2) The database is dropped and recreated to ensure it's clean.
*

* @return Doctrine\DBAL\Connection The database connection instance.
