什么是selenium？javascript

一个用于Web应用程序测试的工具直接运行在浏览器中，就像真正的用户在操做同样。支持的浏览器包括IE（7, 8, 9, 10, 11），Mozilla Firefox，Safari，Google Chrome，Opera等。测试与浏览器的兼容性，测试你的应用程序看是否可以很好得工做在不一样浏览器和操做系统之上。测试系统功能，建立衰退测试检验软件功能和用户需求。php

slenium前世css

早期是直接使用 javascrip 注入技术与浏览器打交道，slenium RC启动一个server 将web元素api转换为javascript。在Selenium内核启动浏览器以后注入这段Javascript，由此才实现了Selenium的目的：自动化Web操做。这种Javascript注入技术的缺点是速度不理想，并且稳定性大大依赖于Selenium内核对API翻译成的Javascript质量高低。html

slenium如今前端

Selenium2.x 提出了WebDriver的概念以后与浏览器交互利用原生的API，直接操做浏览器页面里的元素。不一样的浏览器厂商对Web元素的操做和呈现一些差别直接致使了Selenium WebDriver要分浏览器厂商不一样，而提供不一样的实现。Selenium3.0发布后，最大更新点就是干掉了对selenium rc的支持，后面就一直是webdriver协议，java

WebDriver工做流程python

一、经过WebDriver建立一个浏览器服务，remote server
二、脚本启动时会在新的线程中启动一个浏览器，并绑定特定的端口，没个浏览器有不一样的端口段。
三、client 建立1个session，在该session中经过http请求向remote server发送restful的请求，remote server解析请求，完成相应操做并返回response。
四、分析response，继续执行脚本仍是结束执行
command.py:Command类中定义了WebDriver的一些经常使用的常量。git

remote\webdrvier.py:全部浏览器webdrvier的基类，其中包含了全部webdriver的api接口github

remote\remote_connection.py:包含启动Remote WebDrvier server，执行client请求，self._commands是selenium的核心请求参数，根据对应的Command常量，发送不一样的http请求。web

selenium 中的等待方式：time（固定等待），implicitly_wait（隐式等待），WebDriverWait（显示等待）

webdriver client的原理

当测试脚本启动Chrome的时候，selenium-webdriver 会首先在新线程中启动Chrome浏览器。启动后selenium-webdriver会将Chrome绑定到特定的端口，绑定完成后该chrome实例便做为webdriver的remote server存在；客户端(也就是测试脚本)建立1个会话，在该session中经过http请求向remote server发送请求，remote server解析请求，完成相应操做并返回response；客户端接受response，并分析其返回值以决定是转到第3步仍是结束脚本；

webdriver是按照server – client的经典设计模式设计的。

server端就是remote server，能够是任意的浏览器。当咱们的脚本启动浏览器后，该浏览器就是remote server，它的职责就是等待client（脚本）发送请求并作出相应；

client端简单说来就是咱们的测试代码，咱们测试代码中的一些行为，好比打开浏览器，转跳到特定的url等操做是以http请求的方式发送给被测试浏览器，也就是remote server；remote server接受请求，并执行相应操做，并在response中返回执行状态、返回值等信息；

selenium的搭建
1.在python中安装好selenium包： pip install selenium

2.在配置好浏览器的驱动程序根据http://www.imdsx.cn/index.php/2017/08/02/drvier/ 驱动对照表下载Chrome对驱动，并添加在PATH环境变量中，(或者直接把驱动放在pytho的安装目录下)

Firefox驱动下载地址为：https://github.com/mozilla/geckodriver/releases/ ，

IE浏览器驱动下载地址为：http://selenium-release.storage.googleapis.com/index.html

编写如下代码能打开对应的浏览器就配置成功：

from selenium import webdriver
driver = webdriver.Chrome()
driver.get('http://www.imdsx.cn')

google浏览器

from selenium import webdriver
driver = webdriver.Firefox()
driver.get('http://www.imdsx.cn')

火狐浏览器

from selenium import webdriver
driver = webdriver.Ie()
driver.get('http://www.imdsx.cn')

IE浏览器

selenium定位

import selenium #引用selenium包
from selenium import webdriver#引用包的服务
driver = webdriver.Chrome()#建立浏览器 当作咱们的服务端
driver.get('xxxxxxxxxxxxxxx/')#打开对应测试网站，这里的url 必须带有http
# 8种单数定位方式
# id进行定位
# driver.find_element_by_id('i1').send_keys('123123')#send_keys向文本框输入数字
# class 定位方式
# driver.find_element_by_class_name('classname').send_keys('123123')
# name定位方式
# driver.find_element_by_name('name').send_keys('123123')
# 文案定位
# driver.find_element_by_link_text('新建标签页面').click()  #.click（）表示点击操做
# 文案包含定位方式
js = 'window.scrollTo(0,0);' # 将滚动条调制最上方
driver.execute_script(js)# 执行写好的js
# import time
# # time.sleep(2)#界面若是反应比较慢能够加载等等时间
# driver.find_element_by_partial_link_text('新建标签').click()
# 标签名定位 最不经常使用的
# driver.find_element_by_tag_name('input').send_keys('1111')
# xpath 定位
# driver.find_element_by_xpath('//*[@id="i1"]').send_keys('2222')
# css id  定位
# driver.find_element_by_css_selector('#i1').send_keys('2222')
# # css name  定位
# driver.find_element_by_css_selector('name').send_keys()

8种定位方式

xpath定位

xpath(xpath 定位尽可能少用层级定位，若是开发更改了页面的层级，全部定位都挂了，尽可能属性定位为主，层级为辅助)
        //* 取当前页面的所有元素
        //*[@id='i1'] id 进行定位 @表明引用属性
        //*[@placeholder="请经过ID定位元素"] 
        //input[@placeholder="请经过ID定位元素"] 经过 标签名进一步缩小范围
        //select[4] 若是存在不惟一的状况 能够经过角标进行取值 xpath从1开始取
        //select[@size="4" and @multiple="multiple"]  逻辑定位

xpath定位

当不肯定时能够只用copy直接复制xpath地址（这个地址至关于层级定位最好少用）

css selector定位

css  selector
1.支持ID，class 定位  (# 表明id)  （ . 表示class）
不是说不能用class 若是class属性在页面中惟一，那么是能够等同于id来使用

2.属性定位
[placeholder = "请经过ID定位元素"]  属性定位

3.标签组合定位
input[placeholder = "请经过ID定位元素"] 缩小范围 先定位input 在定位属性

4.多属性组合定位
Css Selector 的多属性组合选择过滤 没有and 只须要多个[] 链接 就能够
select[size = "4"][multiple = "multiple"] 多属性确立惟一

5.层级关系定位
经过  >  来区分层级的界定
select>option[value='3']

6.模糊匹配
^= 匹配元素属性以什么开头
input[value ^= "登"]
$= 匹配属性以什么结尾
input[value$="录"]
*= 匹配属性包含什么值 input
[value *= "录"]

作UI自动化前须要了解什么

1.何时作UI自动化：当项目已经稳定不在大面积修改的状况下，就能够接自动化了。

2.作UI自动化须要了解什么知识：前端HTML，CSS，定位方式

简单的UI自动化框架

1.bin 目录下放程序入口
2.lib 目录下放一些配置文件
3.log 目录下放日志
  （HTMLTestRunne ：生产网页的报告页面，
    logger 生成日志
    path  配置地址
    pyse 定位页元素使用的框架
    tool  生成错误图片）
4.pages 目录下放页面元素、
5.report  目录下放文件运行报告  （picture）下放错误截图
6.test_case 目录下放用例

框架能实现：
1、基于显示等待 解决不稳定的状况
（time：固定等待 ， implicitly_wait: 隐式等待，webDriveWait:显示等待）
2.解决维护麻烦 PO(page object)思想（以一个页面当作一个类，每个页面的功能点当作一个函数）
3.自动化测试用例和页面数据源进行分离。

怎么判断业务逻辑的成功
举例说明：假设是登陆的业务逻辑，判断登陆的特有元素消失 ，就表明登陆成功了。
只有登陆成功了才会出现的元素 判断一下他是否出现

"""
A TestRunner for use with the Python unit testing framework. It
generates a HTML report to show the result at a glance.

The simplest way to use this is to invoke its main method. E.g.

    import unittest
    import HTMLTestRunner

    ... define your tests ...

    if __name__ == '__main__':
        HTMLTestRunner.main()


For more customization options, instantiates a HTMLTestRunner object.
HTMLTestRunner is a counterpart to unittest's TextTestRunner. E.g.

    # output to a file
    fp = file('my_report.html', 'wb')
    runner = HTMLTestRunner.HTMLTestRunner(
                stream=fp,
                title='My unit test',
                description='This demonstrates the report output by HTMLTestRunner.'
                )

    # Use an external stylesheet.
    # See the Template_mixin class for more customizable options
    runner.STYLESHEET_TMPL = '<link rel="stylesheet" href="my_stylesheet.css" type="text/css">'

    # run the test
    runner.run(my_test_suite)
