如何在Python单元测试中设置日志记录级别

import logging
import unittest

logger = logging.getLogger(__name__)

logger.setLevel(logging.DEBUG)  # 设置为DEBUG级别，记录所有日志

console_handler = logging.StreamHandler()
console_handler.setLevel(logging.DEBUG)

formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')

console_handler.setFormatter(formatter)

logger.addHandler(console_handler)

logger.debug('This is a debug message')
logger.info('This is an info message')
logger.warning('This is a warning message')
logger.error('This is an error message')
