在zend框架中运行控制器单元测试时获取"没有为此应用程序定义的默认模块"异常

这是一个已知的错误.
以下是解决此问题的解决方法:

bootstrap = array($this, 'appBootstrap');
        parent::setUp();
    }

    public function appBootstrap()
    {
        $this->_application = new Zend_Application(APPLICATION_ENV,
              APPLICATION_PATH . '/configs/application.ini'
        );
        $this->_application->bootstrap();

        /**
         * Fix for ZF-8193
         * http://framework.zend.com/issues/browse/ZF-8193
         * Zend_Controller_Action->getInvokeArg('bootstrap') doesn't work
         * under the unit testing environment.
         */
        $front = Zend_Controller_Front::getInstance();
        if($front->getParam('bootstrap') === null) {
            $front->setParam('bootstrap', $this->_application->getBootstrap());
        }
    }
}
