Zend FR

Bonjour,
Je n'arrive pas à exécuter des test en utilisant Zend_Test_PHPUnit_ControllerTestCase.
Console Zend Studio m'affiche ceci :

Debug Warning: E:\workspace\library\Zend\Loader.php line 165 - fopen(E:/workspace/appProject/application/default/views\helpers/HeadTitle.php) [<a href='function.fopen'>function.fopen</a>]: failed to open stream: No such file or directory

Debug Error: E:\workspace\library\Zend\Test\PHPUnit\ControllerTestCase.php line 1099 - Call to undefined method IndexControllerTest::incrementAssertionCounter()

Faut-il mettre à jour PHPUnit, et comment faire sous  Zend Studio  6.1?
Merci
