System-level testing of healthcare Internet of Things (IoT_ applications requires creating a test infrastructure with integrated medical devices and third-party applications. A significant challenge in creating such test infrastructure is that healthcare IoT applications evolve continuously with the addition of new medical devices from different vendors and new services offered by different third-party organizations following different architectures. Moreover, creating test infrastructure with a large number of different types of medical devices is time-consuming, financially expensive, and practically infeasible. Oslo City healthcare department faced these challenges while working with various healthcare IoT applications. This paper presents a real-world software architecture (HITA) to create a test infrastructure for healthcare IoT applications. We discuss the quality requirements achieved by HITA and the status of work products developing as a part of HITA. We also present our experiences and lessons learned from the architectural work related to HITA.

翻译：医疗物联网（IoT）应用的系统级测试需要构建一个集成医疗设备和第三方应用的测试基础设施。构建此类测试基础设施的一个重大挑战在于，医疗物联网应用会随着不同供应商的新医疗设备以及不同第三方组织采用不同架构提供的新服务的加入而持续演进。此外，构建包含大量不同类型医疗设备的测试基础设施耗时、成本高昂且实际不可行。奥斯陆市医疗部门在处理各类医疗物联网应用时面临了这些挑战。本文提出了一种用于构建医疗物联网应用测试基础设施的实际软件架构（HITA）。我们讨论了HITA所实现的质量需求，以及作为HITA一部分正在开发的工作产品的状态。我们还分享了与HITA相关架构工作中的经验与教训。
