我是Winium技术的新手，我尝试启动Winium演示测试，但遇到org.openqa.selenium.WebDriverException: org.apache.http.conn.HttpHostConnectException:之类的异常，因此任何人都可以帮助我解决此错误。
我的演示代码：
public static void main(String args[]) throws Exception{
// TODO Auto-generated method stub
String ApplicationPath="C:\\Windows\\System32\\notepad.exe";
DesktopOptions options=new DesktopOptions();
options.setApplicationPath(ApplicationPath);
System.setProperty("webdriver.winium.driver.desktop", "C:\\Users\\DELL\\Downloads\\Winium.Desktop.Driver\\Winium.Desktop.Driver.exe");
WiniumDriver driver=new WiniumDriver(new URL("http://localhost:9999"),options);
}
/// LogCat ///
