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：

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
