最近在搭一个UI自动化测试框架，想把整个搭建过程分享出来，如果有不对的地方，希望大家能够指正，首先创建一个名称为，antomation_framework_demo的工程文件，
pycharm中工程及文件如下图所示：
config:文件中包含调用的浏览器驱动及打开的URL地址
framework:
1、包含定义的页面基类，封装常用的页面操作方法
2、包含打开浏览器操作以及在相对路径下获取浏览器driver
3、日志处理方法
logs:执行日志以时间格式保存在该文件夹下，如：0809162812.txt
pageobjects:定义homepage类，用来处理常用页面操作方法的操作
screenshots:执行截图存放文件，命名格式与日志命名格式一致
test_report:存放执行后生成的测试报告
testsuits:持续集成执行方法
tools:浏览器驱动存放文件夹
好了，具体的包已经创建完成了，现在开始看一下config文件，首先在config文件夹下右键新建->file文件->名称输入config.ini点击确定，打开config.ini，输入如下配置：
#配置文件，只存储浏览器类型和服务器URL #调用的浏览器驱动，保留现在使用的浏览器驱动
[browserType] #browserName = Firefox
browserName = Chrome #browserName = IE #打开URL地址，以百度为例
[testServer] URL =
framework包中文件如下所示：
在framework包下创建base_page.py文件，文件中封装一些页面常用操作方法，可以自己在这个类中进行对应方法的添加，代码如下：
1 # coding=utf-8
2 import time 3 from mon.exceptions import NoSuchElementException 4 import os.path 5 from framework.logger import Logger 6
7 # create a logger instance
8 logger = Logger(logger="BasePage").getlog() 9

11 class BasePage(object): 12 """
13 定义一个页面基类，让所有页面都继承这个类，封装一些常用的页面操作方法到这个类 14 """

browser_engine.py中封装获取根目录下浏览器驱动方法和浏览器操作方法，但需要注意的是，如果在里面使用中文，需要切换方法，但是小编在切换了以后还是不对，可能是因为使用2.7版本python吧，用3.x版本的朋友可以尝试一下使用中文进行日志打印的操作，代码如下：
1 # -*- coding:utf-8 -*-
2 import ConfigParser 3 import os.path 4 from selenium import webdriver 5 from framework.logger import Logger 6
7 logger = Logger(logger="BrowserEngine").getlog() 8
9
10 class BrowserEngine(object): 11 dir = os.path.dirname(os.path.abspath(‘.‘)) # 注意相对路径获取方法
12 chrome_driver_path = dir + ‘/tools/chromedriver.exe‘
13 ie_driver_path = dir + ‘/tools/IEDriverServer.exe‘
14
15 def __init__(self, driver): 16 self.driver = driver 17
18 # read the browser type from config.ini file, return the driver
19 def open_browser(self, driver): 20 config = ConfigParser.ConfigParser() 21 # file_path = os.path.dirname(os.getcwd()) + ‘/config/config.ini‘
22 file_path = os.path.dirname(os.path.abspath(‘.‘)) + ‘/config/config.ini‘
23 config.read(file_path) 24 # 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
25
26 browser = config.get("browserType", "browserName") 27 logger.info("You had select %s browser." % browser) 28 url = config.get("testServer", "URL") 29 logger.info("The test server url is: %s" % url) 30
