Python+Selenium WebUI自动化框架 -- 基础操作封装

前言：

封装Selenium基本操作，让所有页面操作一键调用，让UI自动化框架脱离高成本、低效率时代，将用例的重用性贯彻到极致，让烦人的PO模型变得无所谓，让一个测试小白都能编写并实现自动化。

知识储备前提：熟练python语言理论与实际运用，熟悉selenium库与自动化测试环境配置。

browseroperator.py   浏览器操作

webdriveroperator.py     WEBd页操作

分层设计：基础目录，浏览器操作与WEB操作分开。

一、browseroperator.py 的代码如下：

1、初始化函数def __init__(self)，初始化浏览相关参数

2、初始化浏览器方法def open_url(self, **kwargs)，先判断使用哪种浏览器。

**kwargs是不定长参数，dict格式，参数只需要传 url='www.baidu.com' ,方法调用只用 opr.open_url(url='www.baidu.com')，打开了浏览器，他会返回webdriver的句柄，调用处接收到全流程操作网站元素。

暂时还未封装IE 、火狐，留给各位朋友们实现吧，让我们一起学习

现在我也找了很多测试的朋友，做了一个分享技术的交流群，共享了很多我们收集的技术文档和视频教程。
如果你不想再体验自学时找不到资源，没人解答问题，坚持几天便放弃的感受
可以加入我们一起交流。而且还有很多在自动化，性能，安全，测试开发等等方面有一定建树的技术大牛
分享他们的经验，还会分享很多直播讲座和技术沙龙
可以免费学习！划重点！开源的！！！

3、def close_browser（self, **kwargs）关闭浏览器，齐活，一并封装了

import os
import time
from selenium import webdriver
from common.getconf import Config
from common.getfiledir import BASEFACTORYDIR
 
 
class BrowserOperator(object):
 
    def __init__(self):
        self.conf = Config()
        self.driver_path = os.path.join(BASEFACTORYDIR, 'chromedriver.exe')
 
    def open_url(self, **kwargs):
        """
        打开网页
        :param url:
        :return: 返回 webdriver
        """
        try:
            url = kwargs['locator']
        except KeyError:
            return False, '没有URL参数'
        try:
            type = self.conf.get('base', 'browser_type')   #从配置文件里取浏览器的类型
            if type == 'chrome':
                #处理chrom弹出的info
                # chrome_options = webdriver.ChromeOptions()
                # #option.add_argument('disable-infobars')
                # chrome_options.add_experimental_option("excludeSwitches", ['enable-automation'])
                # self.driver = webdriver.Chrome(options=chrome_options, executable_path=self.driver_path)
                self.driver = webdriver.Chrome(executable_path=self.driver_path)
                self.driver.maximize_window()
                self.driver.get(url)
            elif type == 'IE':
                print('IE 浏览器')
            else:
                print('火狐浏览器')
        except Exception as e:
            return False, e
        return True, self.driver
 
 
 
 
    def close_browser(self, **kwargs):
        """
        关闭浏览器
        :return:
        """
        self.driver.quit()
        return True, '关闭浏览器成功'

二、webdriveroperator.py代码如下

1、def __init__(self, driver:Chrome)，初始化浏览器返回的deriver句柄，

2、内容不一 一 介绍了，实现了所有页面的操作，定义成功与否判断、日志返回等细节。各位看官细细品尝，细节都在代码里，每个方法注释大体可以说明了这个方法意义，很容易看懂。

还有很多UI操作没有搬运上来，留给各位朋友们去实现吧，让我们一起学习

结语：封装了基础类，还得实现一个工厂，实现统一一个入口执行所有自动化
