Selenium ide导出 webdriver 脚本运行浏览器启动与selenium包兼容性

selenium ide 录制脚本以后，导出TestCase.java脚本

1. 新建一个java项目
2. 导入selenium java lib包。下载地址：selenium java版本下载
   http://selenium-release.storage.googleapis.com/index.html
   
3. 把脚本导入项目。
4. 写main方法，实例Testcase 调用setup testcase teardown方法。运行成功
5. 坑：第一:掉不起浏览器：在启动的时候指明浏览器地址：

   System.setProperty("webdriver.firefox.bin", "D:\\Program Files\\Mozilla  Firefox\\firefox.exe"); //指定浏览器路径
   

   第二：java selenium版本与火狐浏览器不兼容：输出台报错

   org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:
