siliconrig 0.2.2

Python SDK and pytest fixtures for siliconrig hardware-in-the-loop testing

siliconrig

Python SDK for siliconrig — remote access to real embedded boards.

Use it in scripts, automation, or as a pytest plugin for hardware-in-the-loop testing.

Install

pip install siliconrig

Quick start

from siliconrig import Client

client = Client()

with client.session(board="esp32-s3") as session:
    session.flash("firmware.bin")
    session.serial.expect("Ready", timeout=10)
    session.serial.send("status\n")
    print(session.serial.read_until("OK", timeout=5))

Or use the Board shorthand:

from siliconrig import Board

with Board("esp32-s3", firmware="build/app.bin") as board:
    board.expect("System ready", timeout=5)
    board.send("gpio set 4 1\n")
    board.expect("GPIO4=HIGH", timeout=2)

pytest plugin

The package includes a pytest plugin that registers automatically. Use it with custom fixtures:

import pytest
from siliconrig import Board

@pytest.fixture
def board():
    with Board("esp32-s3", firmware="build/app.bin") as b:
        yield b

def test_boot_ok(board):
    assert board.expect("System ready", timeout=5)

Or use the built-in siliconrig_board fixture via CLI options:

pytest --siliconrig-board esp32-s3 --siliconrig-firmware build/app.bin tests/hil/

Authentication

Set your API key via environment variable:

export SRIG_API_KEY=key_...

Or pass it directly:

client = Client(api_key="key_...")
