Capturing logs with log_capture in behave

Problem

I run my test with behave (https://behave.readthedocs.io/en/stable/api.html?highlight=log_capture#logging-capture) and after changing to the loguru my tests fail.

I have read this post Issue 59 (regarding basically the same but with pytest), and I understand that loguru doesn’t use standardlib logging which behave log capture probably utilizes, and the way to solve the problem is to propagte the logs to the logging lib

however, I don’t understand how to replicate the fix.

I tried using the fixture in an analogous way but it didn’t seem to work:

Example of what I tried

environment.py

from api.features.fixtures import log_capture_fix


def before_all(context):
    use_fixture(log_capture_fix, context)
    context.config.setup_logging()

fixtures.py

import logging
from behave import fixture
from loguru import logger


@fixture
def log_capture_fix(context):
    class PropogateHandler(logging.Handler):
        def emit(self, record):
            logging.getLogger(record.name).handle(record)

    handler_id = logger.add(PropogateHandler(), format="{message} {extra}")
    yield context.log_capture
    logger.remove(handler_id)

Could you help me configure this properly, or point me in the right directions?

Yeah! Right that might be it 🚀 In hindsight it seems kinda obvious 🤦 . Anyway, thank you very much for helping out Delgan. I will fix it tomorrow to run in correct order during tests, and update here how it went (though I wouldn’t expect further problems now 😄)

UPDATE: Yep. Running the init() at the beggining fo the fixture solved the problem. Once again, thank you very much Delgan 😄

I’m closing this issue since it’s resolved, then. 👍
