Zephyr Application Development Using TDD: Getting Started
summary
Claims that TDD on Zephyr shortens time to market and finds bugs quickly, and demonstrates concrete tooling and techniques: Twister, Zephyr test framework, FFF mocking and link-time substitution for faking DT nodes and drivers. Shows a motion‑detection module (accelerometer + BLE), unit tests driving APIs, a test double for the sensor, Kconfig/device‑tree overlays, thresholds (2 m/s² for 1 s) and idle timeout (5 s with 5‑sample history), and a live BLE demo that works.
