Issue(s) with usage example: fixture 'mqtt_settings' not found

[aaronkurz]

I am encountering issues when trying to execute the basic example.

I am running pytest with this test:

from pytest_mqtt.model import MqttMessage
import pytest


@pytest.mark.capmqtt_decode_utf8
def test_mqtt_send_receive(mosquitto, capmqtt):
    """
    Basic send/receive roundtrip, using text payload (`str`).

    By using the `capmqtt_decode_utf8` marker, the message payloads
    will be recorded as `str`, after decoding them from `utf-8`.
    Otherwise, message payloads would be recorded as `bytes`.
    """
    # Submit a basic MQTT message.
    capmqtt.publish(topic="foo", payload="bar")

    # Demonstrate the "messages" property.
    # It returns a list of "MqttMessage" objects.
    assert capmqtt.messages == [
        MqttMessage(topic="foo", payload="bar", userdata=None),
    ]

    # Demonstrate the "records" property.
    # It returns tuples of "(topic, payload, userdata)".
    assert capmqtt.records == [
        ("foo", "bar", None),
    ]

However, I get the error

file /home/aaron/Developer/factory-activity-detection/mqtt_xes/venv/lib/python3.10/site-packages/pytest_mqtt/mosquitto.py, line 83
  @pytest.fixture(scope="session")
  def mosquitto(mqtt_settings: MqttSettings):
E       fixture 'mqtt_settings' not found

How can I fix this issue?

Furthermore, I noticed that import pytest is missing for the basic usage example.

Dear Aaron,

thanks a stack for your report.

It looks like the most recent release is bogus in this regard. I just observed the same error over here, coming from a Dependabot patch.

• Chore(deps): Update pytest-mqtt requirement from <0.4 to <0.5 daq-tools/lorrystream#95

We will need to look into the issue, and fix it. Apologies for the hiccup, can you work around it by downgrading to the previous version in the meanwhile?

With kind regards,
Andreas.

Hi. We just yanked the release 0.4.0 from PyPI, and there is a patch now, intending to fix the problem.

• Fix command line options machinery #21

Apologies for the delay, release 0.4.1 is upcoming.

pytest-mqtt 0.4.1 has been released and verified on behalf of daq-tools/lorrystream#95. Closing this. Thanks again.

Thank you. Fixed with 3e410fb.
