基于python语言下的UI自动化测试框架搭建（二）

 

framework包中文件如下所示：

 

 

base_page.py:常用操作方法

 

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 selenium.common.exceptions import NoSuchElementException
  4 import os.path

browser_engine.py：浏览器操作方法

 

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 
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()

 

logger.py:日志处理

现在，我们来看一下logger.py中是怎么写的，logger需要实现的功能是要指定保存的日志文件路径，日志级别还有调用文件后将日志存入到指定的文件夹中，日志命名格式为当前案例执行时间并精确到秒，可以保证在执行案例过程中精确的打印出当前案例执行过程的日志。代码如下：

#_*_coding:utf-8 _*_
import logging
import os.path
import time

class 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logger
        self.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%S',time.localtime(time.time()))
        log_path = os.path.dirname(os.path.abspath('.'))+'\logs\\'
        #如果case组织结构式/testsuit/fraturemoddel/xxx.py，那么得到的相对路径的父路径就是项目的根目录
        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handler
        self.logger.addHandler(fh)
        self.logger.addHandler(ch)
    def getlog(self):
        return self.logger
