环境配置
使用selenium+robotframework做UI自动化的第一个比较难搞的问题就是环境搭建，驱动+浏览器的版本匹配很重要，做自动化这么长时间每次都是硬伤，所幸就总结了一整套的环境配置，具体如下。
firefox+webdriver
在刚开始执行程序时出现错误，错误如下：

我上网搜索了一下相关信息，发现是Firefox和webdriver的版本不匹配。
[Selenium]-->[FireFox]
2.25.0 -> 18
2.30.0 -> 19
2.31.0 -> 20
2.42.2 -> 29
2.44.0 -> 33 (不支持31,2014/12/1)
若selenium的版本和firefox不兼容，需要升级selenium的jar包，或者是升级firefox。
selenium之使用chrome浏览器测试（附chromedriver与chrome的对应关系表）
使用WebDriver在Chrome浏览器上进行测试时，需要从http://chromedriver.storage.googleapis.com/index.html网址中下载与本机chrome浏览器对应的驱动程序，驱动程序名为chromedriver；
chromedriver的版本需要和本机的chrome浏览器对应，才能正常使用；
第一步：下载对应版本的chromedriver驱动文件，具体版本请对照文章底部的对应关系表：
如本机的chrome浏览器版本为:版本 61.0.3163.100（正式版本） （64 位），对应的chromedriver版本为2.33.
第二步：下载后把文件解压，然后放到本机chrome浏览器文件路径里，如：
C:\Program Files (x86)\Google\Chrome\Application
第三步：操作完后，就可以使用以下代码直接调起浏览器了：
driver = new ChromeDriver();
附chromedriver与chrome的对应关系表：

同版本的chromedriver下载
http://chromedriver.storage.googleapis.com/index.html
http://npm.taobao.org/mirrors/chromedriver/
配置成功的chromedriver+chrome版本
配了两天的驱动和浏览器，也只配成功了chrome的，内心是崩溃的
Chrome版本的
