require_once 'PHPUnit/Extensions/Database/TestCase.PHP';
class BankAccountDBTest extends PHPUnit_Extensions_Database_TestCase
{
    protected $pdo;

    public function __construct()
    {
        $this->pdo = new PDO('sqlite::memory:');
        BankAccount::createTable($this->pdo);
    }

    protected function getConnection()
    {
        return $this->createDefaultDBConnection($this->pdo,'sqlite');
    }

    protected function getDataSet()
    {
        return $this->createFlatXMLDataSet(dirname(__FILE__).'/_files/empty-seed.xml');
    }

    public function testEmptyTableBehavior() 
    {
        // test stuff
    }
}

我应该使用与createFlatXMLDataSet()不同的方法吗？要么？？？
