Yes—totally doable. Since you’re already using an autouse fixture with

disable_run_logger

, you’ve turned off the APILogHandler (logs-to-API), which is great for tests. To see

get_run_logger().info()

in your terminal, just add a console handler to Prefect’s run loggers during tests. Here are a few options; pick the one that best fits your setup. Option A: Add a console handler in an autouse fixture (recommended) - Keeps API run logging disabled - Prints flow/task run logs to the terminal during tests

import logging
import pytest
from prefect.logging import disable_run_logger
from prefect.logging.handlers import PrefectConsoleHandler

@pytest.fixture(autouse=True)
def prefect_logs_to_terminal():
    # Disable sending run logs to the API
    with disable_run_logger():
        # Add a console handler so run logs show up in the test terminal
        for name in ("prefect.flow_runs", "prefect.task_runs"):
            logger = logging.getLogger(name)
            # avoid duplicates if tests reconfigure logging
            if not any(isinstance(h, PrefectConsoleHandler) for h in logger.handlers):
                logger.addHandler(PrefectConsoleHandler())
            logger.setLevel(<http://logging.INFO|logging.INFO>)
            logger.propagate = False  # avoids duplicate logs via root
        yield

Option B: Use pytest’s built-in live logging - Useful if you prefer pytest to manage printing - Make sure Prefect logs propagate to the root logger 1) Enable live log output in pytest: - Via CLI:

pytest -o log_cli=true --log-cli-level=INFO

- Or in pytest.ini:

[pytest]
log_cli = true
log_cli_level = INFO

2) Ensure Prefect run logs propagate to the root logger:

import logging
import pytest
from prefect.logging import disable_run_logger

@pytest.fixture(autouse=True)
def route_prefect_logs_to_pytest_cli():
    with disable_run_logger():
        for name in ("prefect.flow_runs", "prefect.task_runs"):
            logging.getLogger(name).setLevel(<http://logging.INFO|logging.INFO>)
            logging.getLogger(name).propagate = True
        yield

Option C: Capture logs for assertions and still see them - Uses Prefect’s testing helper to capture run logs - Combine with pytest live logging if you want them printed during runs

import logging
import pytest
from prefect.logging import disable_run_logger
from prefect.testing.fixtures import add_prefect_loggers_to_caplog

@pytest.fixture(autouse=True)
def capture_prefect_logs(caplog):
    with disable_run_logger():
        add_prefect_loggers_to_caplog(caplog)
        caplog.set_level(<http://logging.INFO|logging.INFO>)
        yield

Then enable live logging with

pytest -o log_cli=true --log-cli-level=INFO

(or via pytest.ini) so they show in the terminal too. Notes - The functions/classes referenced above are available in Prefect 3.x: - Run loggers and helpers: prefect.logging.loggers (API) - Handlers: prefect.logging.handlers (API) - Pytest helper: prefect.testing.fixtures (API) - General logging customization: Logging customization guide If you prefer to control everything via a logging config file (and optionally send to both API + console for tests), you can also point

PREFECT_LOGGING_SETTINGS_PATH

at a test-specific YAML that includes both

APILogHandler

and

PrefectConsoleHandler

. Happy to share a minimal YAML if that’s helpful. Do you want the logs printed for all tests, or only on failures? I can tailor the fixture for either behavior.
