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.

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

Features

  endpoint: "$mqtt_endpoint"
  payload: '{
    "endpoint": "$mqtt_endpoint",
    "payload": {
      "obj_id_L": [0],
      "bin_value": [77251432],
      "measure_id": [100],
      "measureType": ["float"],
      "start_time": 1514911926114
    },
    "host": "$mqtt_host",
    "provider": "mqtt",
