With the release of Zend Framework 1.8 lots of things changed internally, and so changed the way to test your applications. My presentation will go in depth into the new unit testing features and will give examples to test your application on several levels like database tables, web services, library components and controllers.Some parts require specific attention in order to ensure a good quality of Tests (e.g. Zend_Application, Zend_Db, Zend_Ldap, Zend_Service, Zend_Controller) while other parts can be included as parts of earlier mentioned tests.
