Think I have a bug but want to check that I'm using these methods correctly. The use of

prefect.get_run_logger()

is incompatible with testing task functions. A minimal example based on the documentation for testing task functions. I only added the two lines defining and using the logger.

import pytest
from prefect import flow, get_run_logger, task
from prefect.testing.utilities import prefect_test_harness

@pytest.fixture(autouse=True, scope="session")
def prefect_test_fixture():
    with prefect_test_harness():
        yield

@task
def my_favorite_task():
    logger = get_run_logger()
    <http://logger.info|logger.info>("running task")
    return 42

@flow
def my_favorite_flow():
    val = my_favorite_task()
    return val

def test_my_favorite_task():
    assert my_favorite_task.fn() == 42

Raises

MissingContextError("There is no active flow or task run context.")

on the call to

prefect.get_run_logger()
