Web自动化测试项目（七）日志

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

log_utils.py

import logging.handlers
import time
class 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 webdriver
from utils.log_utils import GetLogger
logger = 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)
