Jmeter配置使用Selenium

1. 下载Jmeter插件管理工具https://jmeter-plugins.org/downloads/all/
   下载plugins-manager.jar并放到jmeter/lib/ext目录下，然后重启jmeter
2. 在Jmeter的选项下面会多一个Plugins Manager菜单，打开会看到有三个tab，分别是已安装的插件，有效的插件和升级
   在有效的插件下面找到Selenium/WebDriver support安装即可
3. 安装后就可以看到相应的选项了
   
4. 安装会发现在lib下多了几个包
   
5. 要注意的是最新的selenium-api目前是3.6.0了，但是插件还是jmeter-plugins-webdriver-1.4.0，不支持3以上版本，只能用2.*的版本，而2.*的版本对火狐40以后的版本支持不好，我不得已安装了老版本的39才可以正常使用
6. 另一个问题是，安装后运行出错

发现是少了jna的jar包，从http://www.java2s.com/Code/Jar/j/Downloadjna330jar.htm下载即可（jna-3.3.0和jna-3.3.0-platform）

1. 测试脚本参考http://www.cnblogs.com/richaaaard/p/5113161.html
