Some of my tests contain assertions about log output, so changing the log level breaks them. Instead, I changed my Django LOGGING settings to use a NullHandler when running tests:

if 'test' in sys.argv:
    _LOG_HANDLERS = ['null']
else:
    _LOG_HANDLERS = ['console']
    
LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {
        'simple': {
            'format': '%(levelname)s %(message)s'
        },
    },
    'handlers': {
        'null': {
            'level': 'DEBUG',
            'class': 'logging.NullHandler',
        },
        'console': {
            'level': 'DEBUG',
            'class': 'logging.StreamHandler',
            'formatter': 'simple',
        },
    },
    'loggers': {
        'django': {
            'handlers': _LOG_HANDLERS,
            'propagate': True,
            'level': 'INFO',
        },
    }
}
