ESP32 IoT Tutorial

Automated Testing

Automated Testing

Overview

Section titled “Overview”

In IoT hardware development, manual testing is time-consuming and prone to missing edge cases. This chapter introduces how to leverage AI development tools like Trae, combined with USB oscilloscopes, debug serial ports, AI-generated test firmware, and Python scripts, to build a comprehensive automated testing system. By feeding circuit signals back to the computer and jointly analyzing serial logs and waveform data, you can achieve end-to-end automated verification from hardware signals to software logic, significantly improving testing efficiency and coverage.
