Question

我在从Windows 10主机到Linux VM启动Selenium测试时遇到问题。在VM上，我启动了Hub并注册了一个Node。我也可以从我的主机访问Selenium网格接口。

我是否必须手动启动Geckodriver或必须在VM上安装驱动程序？

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

这是我想要触发测试的java类

    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();

  }
}

这是我的stacktrace

您必须在注册节点时设置gecko驱动程序路径，如下所示，并将驱动程序文件下载并保存在驱动器中。

java -Dwebdriver.gecko.driver = -jar -role node -hub http://192.168.20.206:4444/grid/register
