WebDriverException:转发新会话时出错转发请求时转发错误连接到my_ip:5555 [/my_ip]失败:连接超时 [英] WebDriverException: Error forwarding the new session Error forwarding the request Connect to my_ip:5555 [/my_ip] failed: Connection timed out

问题描述

我在AWS窗口上安装了硒节点并启动了它.然后我在AWS Linux上设置了Jenkins，git，Seleniimim集线器.当我在Jenkins上构建应用程序时，Selenium Hub尝试使用私有IP地址连接到AWS Windows的Selenium节点.而且我收到以下异常:

org.openqa.selenium.WebDriverException: 
Error forwarding the new session Error forwarding the request Connect to windows_private_ip:5555 [/windows_private_ip] failed: Connection timed out (Connection timed out)

Caused by: org.openqa.grid.common.exception.GridException: Error forwarding the new session Error forwarding the request Connect to windows_private_ip:5555 [/windows_private_ip] failed: Connection timed out (Connection timed out)

网格节点命令:

C:\Users\Administrator>java -Dwebdriver.chrome.driver=./drivers/windows-driver/chromedriver.exe -jar C:\\Users\\Administrator\\Desktop\\selenium-server-standalone-3.0.1.jar -role node -hub http://ip_address:4444/grid/register

我的代码是:

if (browser.equalsIgnoreCase("FF")) {
            System.setProperty("webdriver.gecko.driver", "drivers/windows-driver/geckodriver.exe");
            DesiredCapabilities cap = DesiredCapabilities.firefox();
            // Set the platform where we want to run our test- we can use
            // MAC and Linux and other platforms as well
            cap.setPlatform(Platform.ANY);
            cap.setCapability("gecko", true);
            // Here you can use hub address, hub will take the
            // responsibility to execute the test on respective node
            URL url = new URL("http://hub_public_ip:4444/wd/hub");
            // Create driver with hub address and capability
            gbb = PageFactory.initElements(new RemoteWebDriver(url, cap), GuruBase.class);
        } else if (browser.equalsIgnoreCase("IE")) {
            System.setProperty("webdriver.ie.driver", "drivers/windows-driver/IEDriverServer.exe");
            gbb = PageFactory.initElements(new InternetExplorerDriver(), GuruBase.class);

        } else if (browser.equalsIgnoreCase("GC")) {
            System.setProperty("webdriver.chrome.driver", "drivers/windows-driver/chromedriver.exe");
            ChromeOptions cho = new ChromeOptions();
            cho.addArguments("disabled-extensions");
            cho.addArguments("--start-maximized");
            gbb = PageFactory.initElements(new ChromeDriver(cho), GuruBase.class);
        }

        else if (browser.equalsIgnoreCase("html")) {
            gbb = PageFactory.initElements(new HtmlUnitDriver(true), GuruBase.class);
        }

我正在Jenkins上运行硒中心.

解决方案

一个快速的解决方案是更改:

java -Dwebdriver.gecko.driver=./drivers/windows-driver/chromedriver.exe -jar C:\\Users\\Administrator\\Desktop\\selenium-server-standalone-3.0.1.jar -role node -hub http://ip_address:4444/grid/register

在将 Dwebdriver.gecko.driver 与 chromedriver.exe

一起使用时

到任一:

• 使用 GeckoDriver :

  java -Dwebdriver.gecko.driver=./drivers/windows-driver/geckodriver.exe -jar C:\\Users\\Administrator\\Desktop\\selenium-server-standalone-3.0.1.jar -role node -hub http://ip_address:4444/grid/register
  

• 使用 Chromedriver :

  java -Dwebdriver.chrome.driver=./drivers/windows-driver/chromedriver.exe -jar C:\\Users\\Administrator\\Desktop\\selenium-server-standalone-3.0.1.jar -role node -hub http://ip_address:4444/grid/register
  

另外，您需要检查if()循环，因为您在System.setProperty()行中混合使用了 Windows 和 Linux 样式，如下所示:

• GeckoDriver :

  System.setProperty("webdriver.gecko.driver", "drivers/windows-driver/geckodriver.exe");
  

• ChromeDriver :

  System.setProperty("webdriver.chrome.driver", "drivers/windows-driver/chromedriver");
  

• IEDriverServer :

  System.setProperty("webdriver.ie.driver", "drivers/windows-driver/IEDriverServer.exe");
  

注意:在 Windows系统上，您需要提及扩展名 .exe ，例如 geckodriver.exe ，而在 Linux Systems 上，您需要删除扩展名 .exe ，例如 chromedriver

I installed selenium node on AWS windows and started it. And I setup Jenkins, git, Seleniuim hub on AWS Linux. When i'm building app on Jenkins, selenium hub is trying to connect to selenium node of AWS windows with private IP address. And i'm getting following exception:

org.openqa.selenium.WebDriverException: 
Error forwarding the new session Error forwarding the request Connect to windows_private_ip:5555 [/windows_private_ip] failed: Connection timed out (Connection timed out)
Command duration or timeout: 190.25 seconds

Caused by: org.openqa.grid.common.exception.GridException: Error forwarding the new session Error forwarding the request Connect to windows_private_ip:5555 [/windows_private_ip] failed: Connection timed out (Connection timed out)

Grid Node command:

C:\Users\Administrator>java -Dwebdriver.chrome.driver=./drivers/windows-driver/chromedriver.exe -jar C:\\Users\\Administrator\\Desktop\\selenium-server-standalone-3.0.1.jar -role node -hub http://ip_address:4444/grid/register

My code is:

if (browser.equalsIgnoreCase("FF")) {
            System.setProperty("webdriver.gecko.driver", "drivers/windows-driver/geckodriver.exe");
            DesiredCapabilities cap = DesiredCapabilities.firefox();
            // Set the platform where we want to run our test- we can use
            // MAC and Linux and other platforms as well
            cap.setPlatform(Platform.ANY);
            cap.setCapability("gecko", true);
            // Here you can use hub address, hub will take the
            // responsibility to execute the test on respective node
            URL url = new URL("http://hub_public_ip:4444/wd/hub");
            // Create driver with hub address and capability
            gbb = PageFactory.initElements(new RemoteWebDriver(url, cap), GuruBase.class);
        } else if (browser.equalsIgnoreCase("IE")) {
            System.setProperty("webdriver.ie.driver", "drivers/windows-driver/IEDriverServer.exe");
            gbb = PageFactory.initElements(new InternetExplorerDriver(), GuruBase.class);

        } else if (browser.equalsIgnoreCase("GC")) {
            System.setProperty("webdriver.chrome.driver", "drivers/windows-driver/chromedriver.exe");
            ChromeOptions cho = new ChromeOptions();
            cho.addArguments("disabled-extensions");
            cho.addArguments("--start-maximized");
            gbb = PageFactory.initElements(new ChromeDriver(cho), GuruBase.class);
        }

        else if (browser.equalsIgnoreCase("html")) {
            gbb = PageFactory.initElements(new HtmlUnitDriver(true), GuruBase.class);
        }

I'm running selenium hub on Jenkins.

解决方案

A quick solution will be to change :

java -Dwebdriver.gecko.driver=./drivers/windows-driver/chromedriver.exe -jar C:\\Users\\Administrator\\Desktop\\selenium-server-standalone-3.0.1.jar -role node -hub http://ip_address:4444/grid/register

As you are using Dwebdriver.gecko.driver with chromedriver.exe

To either :

• Use GeckoDriver :

  java -Dwebdriver.gecko.driver=./drivers/windows-driver/geckodriver.exe -jar C:\\Users\\Administrator\\Desktop\\selenium-server-standalone-3.0.1.jar -role node -hub http://ip_address:4444/grid/register
  

• Use Chromedriver :

  java -Dwebdriver.chrome.driver=./drivers/windows-driver/chromedriver.exe -jar C:\\Users\\Administrator\\Desktop\\selenium-server-standalone-3.0.1.jar -role node -hub http://ip_address:4444/grid/register
  

Additionally, you need to check your if() loop as you have a mixed up representation of Windows and Linux styles in System.setProperty() line as follows :

• GeckoDriver :

  System.setProperty("webdriver.gecko.driver", "drivers/windows-driver/geckodriver.exe");
  

• ChromeDriver :

  System.setProperty("webdriver.chrome.driver", "drivers/windows-driver/chromedriver");
  

• IEDriverServer :

  System.setProperty("webdriver.ie.driver", "drivers/windows-driver/IEDriverServer.exe");
  

Note : On Windows Systems you need to mention the extension .exe part e.g. geckodriver.exe while on Linux Systems you need strip off the extension .exe part e.g. chromedriver
