PHPUnit Zend_Test_PHPUnit_DatabaseTestCase fails to truncate table - zend-framework

Question

I am setting up some db integration testing using Zend_Test_PHPUnit_DatabaseTestCase.
My tests run but the db tables do not get truncated so an add test fails assertion - as the xml I provide as a dataset does not match the db can anybody suggest why
TestCase
class ArtworkDBTest extends DatabaseTestCase
{
public function testAddArtwork()
{
$data=array("artwork_name"=>'test',"description"=>'test',"imgpath"=>'test',"size"=>'test',"price_information"=>'test',"category"=>1,"artwork_order"=>1);
$mockedLog=$this->getMock("Log",array("log"));
$artwork = new shop_Artwork($mockedLog,Zend_Db_Table_Abstract::getDefaultAdapter());
$artwork->addArtwork($data);
$this->assertDataSetsMatchXML('artwork-add.xml', $dataSet);
}
}
Database testing setup code (adapted from dragonbe and ibuildings tutorials)
abstract class DatabaseTestCase extends Zend_Test_PHPUnit_DatabaseTestCase

const DEFAULT_CONNECTION_SCHEMA = 'main';

public function __construct()
{
$this->dataSet = new Zend_Test_PHPUnit_Db_DataSet_QueryDataSet($this->getConnection());
$this->dataSet->addTable('artwork','Select* from artwork');
$this->dataSet->addTable('login','Select *from login');
$this->dataSet->addTable('category','Select *from category');
}
public function getConfiguration()
{
if ($this->__configuration == NULL) {
$this->__configuration = new Zend_Config_Ini(TEST_PATH . '/application/configs/tests.ini');
}
return $this->__configuration;
}
public function getSeedFilesPath()
{
if ($this->_seedFilesPath == NULL) {
$this->_seedFilesPath = $this->getConfiguration()->tests->seeds->folder;
}
return rtrim($this->_seedFilesPath, '/') . '/';
}
protected function getConnection()

}
return $this->_connectionMock;
}
protected function getDataSet()

The answer was running parent::setUp(); inside the test class's setUp() method
