前天看TesterHome提到UI录制做UI自动化，很感兴趣，前来学习学习。
参考：https://github.com/alibaba/uirecorder/blob/master/doc/zh-cn/readme.md
UIRecorder是一款基于WebDriver、Chrome浏览器、NodeJs等方案共同打造的零成本自动化解决方案。
基于几乎零成本的录制方案，我们让任何一个完全没有自动化经验的人，可以1分钟录制出可读性高，且强大的自动化脚本。
让所有开发和测试能够最低成本的获得自动化测试的能力，把重复又枯燥的测试工作全部交给计算机，彻底的提高测试效率，解放我们的生产力。
UIRecorder安装
1. 安装jdk
2. 安装node.js，同时安装了npm,需要加上环境变量
3. 安装cnpm
npm install -g cnpm --registry=https://registry.npm.taobao.org
4. 安装uirecorder
cnpm install uirecorder mocha -g
安装相关依赖：cnpm install jwebdriver expect.js mocha-generators faker --save-dev
5. 下载selenium-standalone和selenium-server-standalone-3.4.0.jar
6. 启动selenium-server
7. 下载chromedriver.exe置于chrome安装目录下和python安装目录下
8. 下载chrome 浏览器59版本以上
9. 录制脚本
cmd切换到D盘 uirecorder目录运行：uirecorder start sample/test4.js
10. 安装Mocha
cnpm install mochawesome
11. 生成测试报告
mocha sample/test4.js --reporter mochawesome
注：如果没有第7步，会报错如下：
1) sample/test4 : chrome "before all" hook:
Error: the string "The path to the driver executable must be set by the webdriver.chrome.driver system property; for more information, see https://github.com/SeleniumHQ/selenium/wiki/ChromeDriver. The latest version can be downloaded from http://chromedriver.storage.googleapis.com/index.html" was thrown, throw an Error :)

at process._tickCallback (internal/process/next_tick.js:188:7)
2) sample/test4 : chrome "after all" hook:
Error: the string "The path to the driver executable must be set by the webdriver.chrome.driver system property; for more information, see https://github.com/SeleniumHQ/selenium/wiki/ChromeDriver. The latest version can be downloaded from http://chromedriver.storage.googleapis.com/index.html" was thrown, throw an Error :)
