本文开始一步一步介绍，如何创建自己的第一个自动化测试框架。这一篇，我们介绍，如何封装自己的日志类和浏览器引擎类。

相关步骤：

1. 打开PyCharm，创建如下格式的项目层级结构，文件名称和我保持一样；

2. 相关文件代码如下

配置文件config.ini相关设计如下：

#  this is config file, only store browser type and server URL[browserType]
#browserName = Firefox
browserName = Chrome
#browserName = IE[testServer]
URL = https://www.baidu.com
#URL = www.google.com
浏览器引擎类browser_engine.py相关脚本代码如下：# -*- coding:utf-8 -*-
import ConfigParser
import os.path
from selenium import webdriver
from framework.logger import Loggerlogger = Logger(logger="BrowserEngine").getlog()class BrowserEngine(object):dir = os.path.dirname(os.path.abspath('.'))  # 注意相对路径获取方法chrome_driver_path = dir + '/tools/chromedriver.exe'ie_driver_path = dir + '/tools/IEDriverServer.exe'def __init__(self, driver):self.driver = driver# read the browser type from config.ini file, return the driverdef open_browser(self, driver):config = ConfigParser.ConfigParser()# file_path = os.path.dirname(os.getcwd()) + '/config/config.ini'file_path = os.path.dirname(os.path.abspath('.')) + '/config/config.ini'config.read(file_path)#config.read(file_path,encoding='UTF-8'), 如果代码有中文注释，用这个，不然报解码错误browser = config.get("browserType", "browserName")logger.info("You had select %s browser." % browser)url = config.get("testServer", "URL")logger.info("The test server url is: %s" % url)if browser == "Firefox":driver = webdriver.Firefox()logger.info("Starting firefox browser.")elif browser == "Chrome":driver = webdriver.Chrome(self.chrome_driver_path)logger.info("Starting Chrome browser.")elif browser == "IE":driver = webdriver.Ie(self.ie_driver_path)logger.info("Starting IE browser.")driver.get(url)logger.info("Open url: %s" % url)driver.maximize_window()logger.info("Maximize the current window.")driver.implicitly_wait(10)logger.info("Set implicitly wait 10 seconds.")return driverdef quit_browser(self):logger.info("Now, Close and quit the browser.")self.driver.quit()

日志类logger.py相关脚本代码如下：

# _*_ coding: utf-8 _*_
import logging
import os.path
import timeclass Logger(object):def __init__(self, logger):'''指定保存日志的文件路径，日志级别，以及调用文件将日志存入到指定的文件中'''# 创建一个loggerself.logger = logging.getLogger(logger)self.logger.setLevel(logging.DEBUG)# 创建一个handler，用于写入日志文件rq = time.strftime('%Y%m%d%H%M', time.localtime(time.time()))# log_path = os.path.dirname(os.getcwd()) + '/Logs/'  # 项目根目录下/Logs 保存日志log_path = os.path.dirname(os.path.abspath('.')) + '/logs/'# 如果case组织结构式 /testsuit/featuremodel/xxx.py ， 那么得到的相对路径的父路径就是项目根目录log_name = log_path + rq + '.log'fh = logging.FileHandler(log_name)fh.setLevel(logging.INFO)# 再创建一个handler，用于输出到控制台ch = logging.StreamHandler()ch.setLevel(logging.INFO)# 定义handler的输出格式formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')fh.setFormatter(formatter)ch.setFormatter(formatter)# 给logger添加handlerself.logger.addHandler(fh)self.logger.addHandler(ch)def getlog(self):return self.logger

页面对象pageobject这里暂不用，下一篇介绍

测试脚本baidu_search.py相关脚本如下：

# coding=utf-8
import time
import unittest
from framework.browser_engine import BrowserEngineclass BaiduSearch(unittest.TestCase):def setUp(self):"""测试固件的setUp()的代码，主要是测试的前提准备工作:return:"""browse = BrowserEngine(self)self.driver = browse.open_browser(self)def tearDown(self):"""测试结束后的操作，这里基本上都是关闭浏览器:return:"""self.driver.quit()def test_baidu_search(self):"""这里一定要test开头，把测试逻辑代码封装到一个test开头的方法里。:return:"""self.driver.find_element_by_id('kw').send_keys('selenium')time.sleep(1)try:assert 'selenium' in self.driver.titleprint ('Test Pass.')except Exception as e:print ('Test Fail.', format(e))if __name__ == '__main__':unittest.main()

工具包，这里把三个浏览器的driver文件都放根目录一个文件夹里，这样别人拷贝这个项目也不需要去下载这些文件。

运行测试脚本baidu_search.py，会在根目录下的logs文件生成日志文件，例如我：

2017-04-19 17:49:06,220 - BrowserEngine - INFO - You had select Chrome browser.
2017-04-19 17:49:06,220 - BrowserEngine - INFO - The test server url is: https://www.baidu.com
2017-04-19 17:49:10,049 - BrowserEngine - INFO - Starting Chrome browser.
2017-04-19 17:49:11,115 - BrowserEngine - INFO - Open url: https://www.baidu.com
2017-04-19 17:49:12,349 - BrowserEngine - INFO - Maximize the current window.
2017-04-19 17:49:12,349 - BrowserEngine - INFO - Set implicitly wait 10 seconds.
