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()
