[解决问题]selenium.remote.UnreachableBrowserException 异常分析并解决问题
I have a set of automations that work fantastically in Firefox and Chrome, and I'd like to launch an instance of IEDriver as well. I've set up IEDriver as per Selenium's Google Code wiki, with the correct path (if I change the path I get a different exception, so it's definitely correct). But for some reason it still can't launch, and just times out. The code to launch it (the last line throws the exception): File ieDriver = new File("C:/Users/whatever/path/IEDriverServer.exe");
System.setProperty("webdriver.ie.driver", ieDriver.getAbsolutePath());
WebDriver ie = new InternetExplorerDriver(); And the exception is: Exception in thread "main" org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

org.openqa.selenium.remote.UnreachableBrowserException: Error communicating with the remote browser
出现这种异常的问题官方给了两种可能的原因:( 官方链接:http://selenium.googlecode.com/git/docs/api/java/org/openqa/selenium/remote/UnreachableBrowserException.html)
Indicates there was a problem communicating with the browser being controlled or the Selenium server. The most common causes for this exception are: 1.The provided server address to RemoteWebDriver is invalid, so the connection could not be established.
2.The browser has died mid-test.
第一种,是说远程ip可能有问题,所有连接不上,这个应该归为一大类,凡是连接其他PC都没有问题,唯独这台电脑有问题,那么毫无疑问,就是ip连接方面的问题。
第二种,浏览器的问题。
我的电脑是ping 都ping 不通,然后关闭掉远程连接的机器的防火墙,ping 的通之后,再连接一下就成功了。
当然也有可能是程序有问题,可参见http://www.cnblogs.com/amosli/p/3409024.html这篇文章。
