Неустранимая ошибка PHPUnit и Magento Bootstrap: Uncaught CredisException

У меня проблема с Magento 1.9 и PHPUNit 7.4. Версия PHP - 7.2.

Под деревом. http - это папка Magento.

Ниже bootstrap.php.

//bootstrap.php
class Bootstrap {
    public function __construct() {
        echo "Loading Magento\n";

        # ABSOLUTE PATH SERVER
        require_once( getcwd().'/http/app/Mage.php' );
        echo "require_once Mage\n";

        Mage::app(); <--- Error
        echo "start Mage::app()\n";

Наконец, сообщение об ошибке:
