class DBTestConnector: (source)

Known subclasses: twisted.test.test_adbapi.FirebirdConnector, twisted.test.test_adbapi.MySQLConnector, twisted.test.test_adbapi.PsycopgConnector, twisted.test.test_adbapi.PyPgSQLConnector, twisted.test.test_adbapi.PySQLite2Connector, twisted.test.test_adbapi.SQLite3Connector

A class which knows how to test for the presence of and establish a connection to a relational database.

To enable test cases which use a central, system database, you must create a database named DB_NAME with a user DB_USER and password DB_PASS with full access rights to database DB_NAME.

Method	`can_connect`	Return true if this database is present on the system and can be used in a test.
Method	`getPoolArgs`	Return a tuple (args, kw) of list and keyword arguments that need to be passed to ConnectionPool to create a connection to this database.
Method	`makePool`	Create a connection pool with additional keyword arguments.
Method	`setUp`	Undocumented
Method	`startDB`	Take any steps needed to bring database up.
Method	`stopDB`	Bring database down, if needed.
