Phpunit 如何从脚本运行civicrm的单元测试？

我执行此命令行以运行单元测试：

哈坦。hadrich@pc_Hatem_Hadrich：/projet/tools$php/scripts/phpunit CRM\u AllTests

当我从本地实例运行单元测试时，我遇到了这个错误，我找不到解决它的方法。任何人都可以帮助我修复这个错误

PHP Fatal error:  Class 'CiviTestSuite' not found in /projet/../civicrm/tests/phpunit/CRM/AllTests.php on line 39

我已找到修复此错误的方法，您必须为CiviTest内的引导文件要求一个：

define('DRUPAL_ROOT', '/path_to_project'); 
require_once DRUPAL_ROOT . '/includes/bootstrap.inc';
