How To Disable Logging While Running Django Unit Tests?

By Disabling Tests At The Start Of The Application

Suppose you want to do it the quick way. In that case, the following line of code will disable any log messages less severe or equal to CRITICAL:

logging.disable(logging.CRITICAL)

Copied!

In settings.py Globally

You can also paste these lines of code in your settings.py file, so you do not need to paste the first line multiple times:

import sys
import logging

if len(sys.argv) > 1 and sys.argv[1] == 'test':
    logging.disable(logging.CRITICAL)

Copied!

sys.argv list contains the command-line arguments passed to the script. If some tests are found, logging will be disabled.

Using Filters

While this will not disable the logging globally, you will have more options to go with while developing your application. Create your filter in the settings.py file:

from logging import Filter

class NotInTestingFilter(Filter):

    def filter(self, record):
        from django.conf import settings

        return not settings.TESTING_MODE

Copied!

In the same file, create a variable in which you will say to the program if you are running in the testing mode:

TESTING_MODE = True

Copied!

Then add this filter to your logging configuration:

'filters': {
        'testing': {
            '()': NotInTestingFilter
        }
    },

Copied!

And assign it to a handler:

'filters': ['testing']

Copied!
