Quality and reliability metrics play an important role in the evaluation of the state of a system during the development and testing phases, and serve as tools to optimize the testing process or to define the exit or acceptance criteria of the system. This study provides a consolidated view on the available quality and reliability metrics applicable to Internet of Things (IoT) systems, as no comprehensive study has provided such a view specific to these systems. The quality and reliability metrics categorized and discussed in this paper are divided into three categories: metrics assessing the quality of an IoT system or service, metrics for assessing the effectiveness of the testing process, and metrics that can be universally applied in both cases. In the discussion, recommendations of proper usage of discussed metrics in a testing process are then given.

物联网系统的质量和可靠性指标：综合视图

质量和可靠性指标在开发和测试阶段的系统状态评估中起着重要作用，并充当优化测试过程或定义系统退出或接受标准的工具。这项研究提供了适用于物联网（IoT）系统的可用质量和可靠性指标的综合视图，因为没有全面的研究提供针对这些系统的特定视图。本文中分类和讨论的质量和可靠性指标分为三类：评估IoT系统或服务质量的指标，评估测试过程有效性的指标以及在两种情况下均可普遍使用的指标。在讨论中，
