最近在搭一個UI自動化測試框架，想把整個搭建過程分享出來，如果有不對的地方，希望大家能夠指正，首先創建一個名稱為，antomation_framework_demo的工程文件，

pycharm中工程及文件如下圖所示：

config:文件中包含調用的瀏覽器驅動及打開的URL地址

framework:

1、包含定義的頁面基類，封裝常用的頁面操作方法

2、包含打開瀏覽器操作以及在相對路徑下獲取瀏覽器driver

3、日志處理方法

logs:執行日志以時間格式保存在該文件夾下，如：20190809162812.txt

pageobjects:定義homepage類，用來處理常用頁面操作方法的操作

screenshots:執行截圖存放文件，命名格式與日志命名格式一致

test_report:存放執行后生成的測試報告

testsuits:持續集成執行方法

tools:瀏覽器驅動存放文件夾

好了，具體的包已經創建完成了，現在開始看一下config文件，首先在config文件夾下右鍵新建->file文件->名稱輸入config.ini點擊確定，打開config.ini，輸入如下配置：

#配置文件，只存儲瀏覽器類型和服務器URL #調用的瀏覽器驅動，保留現在使用的瀏覽器驅動

[browserType] #browserName = Firefox

browserName = Chrome #browserName = IE #打開URL地址，以百度為例

[testServer] URL = https://www.baidu.com

framework包中文件如下所示：

在framework包下創建base_page.py文件，文件中封裝一些頁面常用操作方法，可以自己在這個類中進行對應方法的添加，代碼如下：

1 # coding=utf-8

2 import time 3 from selenium.common.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

10

11 class BasePage(object): 12 """

13 定義一個頁面基類，讓所有頁面都繼承這個類，封裝一些常用的頁面操作方法到這個類 14 """

browser_engine.py中封裝獲取根目錄下瀏覽器驅動方法和瀏覽器操作方法，但需要注意的是，如果在里面使用中文，需要切換方法，但是小編在切換了以后還是不對，可能是因為使用2.7版本python吧，用3.x版本的朋友可以嘗試一下使用中文進行日志打印的操作，代碼如下：

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(‘.‘)) # 注意相對路徑獲取方法

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‘), 如果代碼有中文注釋，用這個，不然報解碼錯誤

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

31 if browser == "Firefox": 32 driver = webdriver.Firefox() 33 logger.info("Starting firefox browser.") 34 elif browser == "Chrome": 35 driver = webdriver.Chrome(self.chrome_driver_path) 36 logger.info("Starting Chrome browser.") 37 elif browser == "IE": 38 driver = webdriver.Ie(self.ie_driver_path) 39 logger.info("Starting IE browser.") 40

41 driver.get(url) 42 logger.info("Open url: %s" % url) 43 driver.maximize_window() 44 logger.info("Maximize the current window.") 45 driver.implicitly_wait(10) 46 logger.info("Set implicitly wait 10 seconds.") 47 return driver 48

49 def quit_browser(self): 50 logger.info("Now, Close and quit the browser.") 51 self.driver.quit()
