Show logging output when using pytest Follow

A code example and steps to reproduce would be very helpful in identifying the issue

here is the test code:

import logging
logger = logging.getLogger(__name__)


def test_logging():
    for i in range(10**2):
        print('aaa')
        logger.critical('bbb')
        logger.debug('ccc')
    assert True

I cannot see the print and logger output until the test is over. In practice, I need to see all of them real time

I would say a more proper-ish way would be to log into a file and then tail it. That's what logging is used for, otherwise just use prints.

import logging

logging.basicConfig(
    filename='test.log',
    filemode='w',
    level=logging.ERROR,
    format = '%(asctime)s - %(levelname)s: %(message)s',
)

def test_logging():
    for i in range(10**2):
        print('aaa')
        logging.critical('bbb')
        logging.debug('ccc')
    assert True

Hi Andrey,

agree in general with your comment about logging usage, but using logging as if it is print during development is really helpful...

In fact I found out that it's a supported feature by pytest https://docs.pytest.org/en/latest/logging.html#live-logs .

By creating a pytest.ini file with this content:

[pytest]
log_cli = true

and adding this parameter

--log-cli-level=10

to pytest run configuration, I got what I wanted :)
