自动化测试（六）python-自定义日志类（logging）

import logging
import sys
import os

class failureFilter(logging.Filter):
    def filter(self, record):
        if 'Failure' in record.msg:
            return True
        return False

logger = logging.getLogger(__name__)
logger.setLevel(logging.INFO)

abspath = os.path.dirname(os.path.abspath(__file__)) # 脚本绝对路径
logname = os.path.join(abspath, 'file.log')

## 创建处理器 handlers
console_handler = logging.StreamHandler(stream=sys.stdout) # 输出到控制台
file_handler    = logging.FileHandler(logname) # 输出到文件
console_handler.setLevel(logging.WARNING)
file_handler.setLevel(logging.ERROR)

## 添加filter
loggingFiletr = failureFilter()
console_handler.addFilter(loggingFiletr)
file_handler.addFilter(loggingFiletr)

## 创建格式器
console_format = logging.Formatter('%(name)s - %(levelname)s - %(message)s', '%Y%m%d-%H:%M:%S')
file_format    = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s', '%Y%m%d-%H:%M:%S')

## 将格式器添加到处理器中
console_handler.setFormatter(console_format)
file_handler.setFormatter(file_format)

## 将处理器添加到logger
logger.addHandler(console_handler)
logger.addHandler(file_handler)

logger.info('Info 级别日志信息')
logger.error('Failure')
