如何在其他文件中使用Conftest.py中创建的日志文件？

Question

I have following setup

../test/dirA
../test/Conftest.py
../test/Test_1.py
../test/logging.config

Code for Conftest.py

import logging.config
from os import path
import time
config_file_path = path.join(path.dirname(path.abspath(__file__)), 'logging.conf')
log_file_path = path.join(path.dirname(path.abspath(__file__)), ‘logFile.log’)
logging.config.fileConfig(config_file_path)

logger = logging.getLogger(__name__)

fh = logging.FileHandler(log_file_path)
fh.setLevel(logging.DEBUG)
ch = logging.StreamHandler()
ch.setLevel(logging.ERROR)

# add the handlers to the logger
logger.addHandler(fh)
logger.addHandler(ch)

logging.info('done')

Code for ../test/Test_1.py

import logging
logger = logging.getLogger(__name__)

def test_foo():
    logger = logging.getLogger(__name__)
    logger.info("testing foo")

def test_foobar():
    logger = logging.getLogger(__name__)
    logger.info("testing foobar")

I need to see logs from both files in logFile.log but currently I see only log from conftest.py. What am I missing?

Also, I noticed that if I execute Conftest.py from test folder (one dir up), for some reason it does not see logging.config.

Is my usage for conftest for correct for logging? How else I can achieve same result?

Thank you

With some changes, this addresses my question. Another lesson I learned that use

 logging.getLogger(__name__)

at function level, not at module level. You can see a lots of example out there (including this article, I did it just for giving example in short) get logger at module level. They looks harmless, but actually, there is a pitfall – Python logging module respects all created logger before you load the configuration from a file, if you get logger at the module level like this

Well, my first guess is that if you don't import the Conftest.py in the test_1.py, the logger setup code is not reached and executed, so the logging in the Test_1 file is in a default location log file.

Try this line to find the location of the log file:

logging.getLoggerClass().root.handlers[0].baseFilename
