 /**
- * 管理员功能完整性测试脚本
- * 测试范围：
- * 1. 用户管理 - 用户列表、搜索、封禁/解封、删除、修改存储权限、查看用户文件
- * 2. 系统设置 - SMTP邮件配置、存储配置、注册开关、主题设置
- * 3. 分享管理 - 查看所有分享、删除分享
- * 4. 系统监控 - 健康检查、存储统计、操作日志
- * 5. 安全检查 - 管理员权限验证、敏感操作确认
+ * 管理员功能完整性测试脚本（Cookie + CSRF 认证模型）
+ *
+ * 覆盖范围：
+ * 1. 鉴权与权限校验
+ * 2. 用户管理（列表、封禁/删除自保护、存储权限）
+ * 3. 系统设置（获取/更新/参数校验）
+ * 4. 分享管理
+ * 5. 系统监控（健康、存储、日志）
+ * 6. 上传工具接口
