一、日志作用

• 调试程序
• 了解系统程序运行的情况，是否正常
• 系统程序运行故障分析与问题定位
• 用来做用户行为分析和数据统计

二、为项目添加日志

└── utils ├── log_utils.py └── se_utils.py

log_utils.py

import logging.handlersimport timeclass GetLogger(): logger = None @classmethod def get_logger(cls): if cls.logger == None: # 日志器实例 cls.logger = logging.getLogger() # 设置日志级别 cls.logger .setLevel(level=logging.INFO) # 控制台处理器实例 ch = logging.StreamHandler() # 以时间切分日志文件处理器 filename = '../logs' + '/' + time.strftime('%Y%m%d') + 'WebUiTestLog.log' th = logging.handlers.TimedRotatingFileHandler(filename=filename, when='midnight', interval=1, backupCount=30, encoding='utf-8') # 设置日志格式 fmt = "%(asctime)s %(levelname)s [%(name)s] [filename: %(filename)s - moudle: %(module)s - func: %(funcName)s %(lineno)d line] - %(message)s" fm = logging.Formatter(fmt) # 将日志格式添加到处理器 ch.setFormatter(fm) th.setFormatter(fm) # 将处理器添加到日志器 cls.logger .addHandler(ch) cls.logger .addHandler(th) return cls.logger

se_utils.py 添加浏览器启动和关闭的日志

from selenium import webdriverfrom utils.log_utils import GetLoggerlogger = GetLogger.get_logger()class Driver(): _driver = None @classmethod def get_driver(cls, browser_name='Chrome'): if cls._driver == None: logger.info('正在打开浏览器.....') if browser_name == 'Chrome': cls._driver = webdriver.Chrome() elif browser_name == 'Firefox': cls._driver = webdriver.Firefox() elif browser_name == 'Safari': cls._driver == webdriver.Safari() elif browser_name == 'Opera': cls._driver == webdriver.Opera() elif browser_name == 'edge': cls._driver == webdriver.Edge() elif browser_name == 'Ie': cls._driver == webdriver.Ie() else: raise NameError( "Not found %s browser,You can enter 'Chrome', 'Firefox', 'Ie', 'Edge', 'Safari',Opera" % browser_name) logger.info('打开{}浏览器'.format(cls._driver.name)) return cls._driver @classmethod def quit_driver(cls): if cls._driver: logger.info('正在关闭{}浏览器'.format(cls._driver.name)) cls._driver.quit() logger.info('已关闭{}浏览器'.format(cls._driver.name)) cls._driver = None

base_page.py 添加定位信息的日志

 def find_element(self, locator): try: WebDriverWait(driver=self.driver, timeout=TIMEOUT, poll_frequency=POLL_FREQUENCY).until( EC.visibility_of_element_located(locator)) return self.driver.find_element(*locator) except Exception as e: msg = "元素定位超时 {}: {}".format(locator[0], locator[-1]) logger.error(msg) raise TimeoutException(msg)

更多日志信息请根据例子麻烦自行添加
