以下是我遇到异常的详细信息:

当我使用以下命令启动节点时，出现如下错误:

F:\SeleniumGrid\Jars>java -jar selenium-server-standalone-3.0.0-beta2.jar -role webdriver -hub http://HubIpAddress:4444/grid/register -browser browserName=”firefox”, version=ANY, platform=VISTA, maxInstances=5 -Dwebdriver.gecko.driver.exe

Exception in thread “main” com.beust.jcommander.ParameterException: Was passed main parameter ‘version=ANY,’ but no main parameter was defined at com.beust.jcommander.JCommander.getMainParameter(JCommander.java:914) at com.beust.jcommander.JCommander.parseValues(JCommander.java:759) at com.beust.jcommander.JCommander.parse(JCommander.java:282) at com.beust.jcommander.JCommander.parse(JCommander.java:265) at com.beust.jcommander.JCommander.(JCommander.java:210) at org.openqa.grid.selenium.GridLauncherV3$3.setConfiguration(GridLauncherV3.java:231) at org.openqa.grid.selenium.GridLauncherV3.buildLauncher(GridLauncherV3.java:130) at org.openqa.grid.selenium.GridLauncherV3.main(GridLauncherV3.java:67)

如果我在上面的命令中做错了什么，请告诉我。

下面是使用的java代码:

package com.test.grid;

import org.openqa.selenium.Platform;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.remote.DesiredCapabilities;

import java.net.MalformedURLException;
import java.net.URL;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testng.Assert;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;


public class SelGrid {




    WebDriver driver;
    String baseUrl, nodeURL, hubURL;
    @BeforeTest
    public void setUp() throws MalformedURLException {

    baseUrl = "https://www.google.co.in/";
    hubURL = "http://HubIpAddress:4444/wd/hub";

    DesiredCapabilities capability = DesiredCapabilities.firefox();
    capability.setBrowserName("firefox");
    capability.setPlatform(Platform.VISTA);


    driver = new RemoteWebDriver (new URL(hubURL), capability);

    }

    @AfterTest
    public void afterTest()
    {
        driver.quit();
    }

    @Bài kiểm tra
    public void simpleTest()
    {
        driver.get(baseUrl);
        Assert.assertEquals("Welcome: Mercury Tours", driver.getTitle());
    }

}

您需要更改在 Selenium 3 中调用 -Dwebdriver 参数的顺序。为避免此问题，请确保 -Dwebdriver 始终位于 -jar 调用之前。您需要在 nodeConfig.json 中添加集线器注册和节点配置。

F:\SeleniumGrid\Jars>java -Dwebdriver.gecko.driver.exe -jar selenium-server-standalone-3.0.0-beta2.jar -role node -nodeConfig nodeConfig.json

示例节点配置

{
  "capabilities":
  [
    {
      "browserName": "firefox",
      "maxInstances": 5,
      "seleniumProtocol": "WebDriver"
    },
    {
      "browserName": "chrome",
      "maxInstances": 5,
      "seleniumProtocol": "WebDriver"
    },
    {
      "browserName": "internet explorer",
      "maxInstances": 1,
      "seleniumProtocol": "WebDriver"
    }
  ],
  "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
  "maxSession": 5,
  "port": 5555,
  "register": true,
  "registerCycle": 5000,
  "hub": "http://localhost:4444",
  "nodeStatusCheckTimeout": 5000,
  "nodePolling": 5000,
  "role": "node",
  "unregisterIfStillDownAfter": 60000,
  "downPollingLimit": 2,
  "debug": false,
  "servlets" : [],
  "withoutServlets": [],

}
