問題：
運行用例時，出現報錯（host文件已加入127.0.0.1 localhost）：
raise WebDriverException("Can not connect to the Service %s" % self.path) selenium.common.exceptions.WebDriverException: Message: Can not connect to the Service IEDriverServer.exe
而右下角event log也報錯。
15:54 Cannot start internal HTTP server. Git integration, JavaScript debugger and LiveEdit may operate with errors. Please check your firewall settings and restart PyCharm
解決：控制面板-windows防火牆-允許程序通過防火牆
勾選IEdriverserver.exe→確定，即可解決！！
