Selenium Grid - 在Linux VM上啓動測試

Question

我在啓動從Windows 10主機到Linux VM的Selenium測試時遇到問題。 在VM上我啓動了Hub並註冊了一個節點。我也能夠從我的主機訪問Selenium網格界面。

我必須手動啓動Geckodriver還是必須在VM上安裝驅動程序？

我使用Selenium Standalone 3.5.3，我的VM上的Firefox版本是52.2.0。

這是我的java類，我想觸發測試

package service; 

import junit.framework.TestCase; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.remote.DesiredCapabilities; 
import org.openqa.selenium.remote.RemoteWebDriver; 

import java.net.URL; 

public class TestTest { 

    private static WebDriver driver; 

    public static void main(String[] args) throws Exception { 

    System.setProperty("driver.gecko.driver", "src/main/resources/geckodriver.exe"); 

    String Node = "http://192.168.20.206:4444/wd/hub"; 
    DesiredCapabilities capabilities = DesiredCapabilities.firefox(); 

    driver = new RemoteWebDriver(new URL(Node), capabilities); 

    driver.navigate().to("http://www.DemoQA.com"); 
    Thread.sleep(5000); 
    driver.quit(); 

    } 
} 

這是我的堆棧跟蹤

你必須設置在您註冊的壁虎驅動程序路徑下面給出的節點，並將驅動程序文件下載並保存在驅動器中。
