Test log: info and warning never show up

[aeschli]

Testing #22291

class TestLogger(unittest.TestCase):
    def test_logging(self):
        logger = logging.getLogger(__name__)
        #logger.setLevel(logging.DEBUG)  # Set the desired log level
        logger.setLevel(logging.INFO)  # Set the desired log level

        logger.debug("This is a debug message in a unittest.")
        logger.info("This is an info message in a unittest.")
        logger.warning("This is a warning message in a unittest.")
        logger.error("This is an error message in a unittest.")
        logger.critical("This is a critical message in a unittest.")

        # Printing to stdout and stderr
        print("This is a stdout message.")
        print("This is a stderr message.", file=sys.stderr)

Regardless of log level, logger.debug and logger.info never show up in the Python test log. Is that expected?

hm yes I am able to repro, will investigate! Thanks

Running v2023.20.0, I see a similar behavior. stderr and warning appears in the "Test result" ouput, but not on the specific tests. Would be very nice to get the output on the specific tests.

Example:

import warnings
import sys


def test_that_fails():
    warnings.warn('Looks like something might be wrong...')
    sys.stderr.write('Some stderr output indicating problems\n')
    assert False

Output showing the "Test result output", which includes stderr and warnings:

Output of the specific test that does not show stderr and warnings:

Hi @Bjoernolav thank you for your comment! Currently this is not possible as a functionality. Pytest does not tie output printed to stdout to the given test which produced it. Therefore we are unable to take the given output and say it is due to a specific test without running each test individually and awaiting all output responses which would be contrary to the how pytest designed it. Sorry!

Hi @Bjoernolav, I was mistaken before and I can correlate specific output to a given test. I created an issue for this feature request which you can find here: #22594. Please upvote to demonstrate interest as this will help prioritize it. Thanks

Because we have not heard back with the information we requested, we are closing this issue for now. If you are able to provide the info later on, then we will be happy to re-open this issue to pick up where we left off.

Happy Coding!
