play mqtt

pytest-play support for MQTT support.

Thanks to play_mqtt you can test the integration between a mocked IoT device that sends commands on MQTT and a reactive web application with UI checks.

You can also build a simulator that generates messages for you.

More info and examples on:

• pytest-play, documentation
• cookiecutter-qa, see pytest-play in action with a working example if you want to start hacking
