我在做什么？

步骤1：启动毂

集线器是中心点将接收所有的测试请求和分发它们的正确节点。

打开命令提示符并导航到您复制了selenium-server-standalone文件的目录。键入以下命令：

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

第2步：启动节点

不管你是否要运行新的webdriver功能在一个网格，或使用Selenium 1 RC功能一格，或两者同时，您使用相同的selenium-server-standalone jar文件来启动节点。

java -jar selenium-server-standalone-2.14.0.jar -role node -hub http://localhost:44444/grid/register（44444这里是我工作的环境）

Answer 1

这是由于硒和Firefox之间的兼容性问题。

您需要升级到最新的硒服务器2.44。

Answer 2

是的！正如alec [xe建议这是由于Firefox和硒之间的兼容性问题。对于高于30的Firefox版本，您必须使用硒2.44版本。 Here's硒的更新日志请看看，并决定哪个版本的硒将满足您的要求。
