# HIL Tests

This directory is reserved for a future pytest-based hardware-in-the-loop suite.

Planned capabilities:

- sender and receiver serial capture;
- configurable serial ports and baud rates;
- controlled reset and power-cycle adapters;
- UART smart-meter simulation;
- test MQTT broker integration;
- controlled Wi-Fi outage and AP fallback checks;
- optional SD fault injection.

Keep hardware configuration out of source control. Use ignored files such as:

- `hil_tests/config.local.yaml`
- `hil_tests/ports.local.json`
- `hil_tests/secrets.local.yaml`

Do not run HIL against untrusted pull-request code on a hardware runner.
