Design and implementation of an interface architecture for automated IoT device testing platforms

This paper presents the design and validation of a modular interface architecture for automated testing of IoT devices. The proposed system integrates asynchronous communication, real-time environmental data visualization, and support for multiple network protocols such as MQTT and HTTP/REST. The backend is implemented in Python using FastAPI, while the frontend utilizes a custom GUI developed in Tkinter. Testing was performed under normal, boundary, and failure conditions, with both simulated and physical sensor inputs. Results show reduced manual effort, improved reproducibility, and compatibility with CI/CD workflows.
