cannot configure DatasourceDatabaseTester

The way DatasourceDatabaseTester implements getConnection() is by creating a new object each time:
public IDatabaseConnection getConnection() throws Exception
{
logger.debug("getConnection() - start");

    assertTrue\( "DataSource is not set", dataSource\!=null \);
    return new DatabaseConnection\( dataSource.getConnection\(\), getSchema\(\) \);
\}

Calling getConfig() on the returned object will then have no effect since the next call to getConnection() (by the framework) will get a completely new object, which will obviously not have your customizations.

Is this as simple as caching the IDatabaseConnection in that tester?
