java - 无法创建新的远程 session - Selenium webdriver

Question

我遇到异常

Exception in thread "main" org.openqa.selenium.SessionNotCreatedException: Unable to create new remote session. desired capabilities = Capabilities [{marionette=true, browserName=firefox, version=48.0.1, platform=ANY}], required capabilities = Capabilities [{}]' while trying to run selenium script in a remote web driver.

集线器和节点配置正确，能够相互通信。

• Selenium 网络驱动程序:3.0
• 平台:Windows server 2012 R2。
• Firefox 版本:48.0.1

我的脚本中使用的代码:

       System.setProperty("webdriver.gecko.driver", "mypath/geckodriver.exe");
     DesiredCapabilities capabilities = DesiredCapabilities.firefox(); 
     capabilities.setCapability("marionette", true);
     capabilities.setBrowserName("firefox");
     capabilities.setPlatform(Platform.ANY);

     RemoteWebDriver driver =new RemoteWebDriver(new URL("http://ipofthenode:4444/wd/hub"), capabilities);

     driver.get("http://stackoverflow.com");

     System.out.println("executed");

Answer 1

创建一个.bat文件添加下面的命令

C:\Selenium_Grid
start java -Dwebdriver.gecko.driver=C:\Selenium_Grid\geckodriver\geckodriver.exe -jar C:\Selenium_Grid\selenium-server-standalone-3.0.1.jar -role node -hub http://localhost:4444/grid/register -browser browserName=firefox -port 5555

(用你的替换路径)

然后在执行代码之前启动.bat 文件
