无法启动新浏览器会话：org.openqa.selenium.server.RemoteCommandException:在会话上启动浏览器时出错null

我在做什么

步骤1：启动集线器

集线器是接收所有测试请求并将它们分发到正确节点的中心点

打开命令提示符并导航到复制selenium server独立文件的目录。键入以下命令：

java-jar-selenium-server-standalone-2.14.0.jar-role hub

步骤2：启动节点

无论您是希望运行具有新WebDriver功能的网格，还是运行具有Selenium 1 RC功能的网格，或者同时运行两者，都可以使用相同的Selenium server独立jar文件来启动节点

---

java-jar-selenium-server-standalone-2.14.0.jar-role-node-hubhttp://localhost:44444/grid/register

（这里44444是我工作的环境）

这是由于selenium和firefox之间的兼容性问题

您现在需要升级到最新的selenium服务器。

是！正如alec[xe所建议的，这是由于firefox和selenium之间的兼容性问题。对于高于30的firefox版本，您必须使用selenium 2.44版本。selenium的变更日志请查看并决定哪个版本的selenium将满足您的要求

现在，我收到以下错误：异常“RuntimeException”，消息为“访问位于“”的Selenium服务器时响应无效：在30000ms后超时”phar:///usr/bin/phpunit/phpunit-selenium/Extensions/SeleniumTestCase/Driver.php:1066 请提供帮助！！phpunit版本4.4.5是否验证服务器正在运行？打开browser并转到中心。查看中心支持的浏览器。确保firefox是其中之一。我们可以看看您如何构建远程驱动程序的代码吗？
