使用applicationName功能在特定的硒节点上运行ui测试

如何解决使用applicationName功能在特定的硒节点上运行ui测试

使用applicationName在特定的硒节点上运行测试时遇到一些问题。如果我仅通过chrome选项，则一切正常，但在随机节点上，如果我添加applicationName或任何其他功能，它将失败。

        options.AddArguments(new[]
        {
            "no-sandbox","disable-gpu","window-size=1920,1200","disable-infobars","disable-extensions","disable-print-preview","ignore-certificate-errors","no-proxy-server","proxy-server='direct://'","proxy-bypass-list=*"
        });

        //if i add applicationName,test fails
        //options.AddAdditionalCapability("applicationName","test");

        var driver = new RemoteWebDriver({huburl},options);

节点config.json文件：

{
   "registerCycle":5000,"hub":"http://qa-sel-node-linux.linn.local:4444","register":true,"capabilities":[
      {
         "applicationName":"test","maxInstances":20,"platform":"LINUX","seleniumProtocol":"WebDriver","chromeOptions":{
            "args":[
               "headless","no-sandbox","window-size=1920x1200"
            ]
         },"browserName":"chrome"
      }
   ],"nodeStatusCheckTimeout":5000,"unregisterIfStillDownAfter":1000,"role":"node","proxy":"org.openqa.grid.selenium.proxy.DefaultRemoteProxy","downPollingLimit":1,"maxSession":20,"port":5555,"nodePolling":1000
}

这是我启动节点的方式：

java -Dwebdriver.chrome.driver=/usr/bin/chromedriver -jar selenium-server-standalone-3.141.59.jar -role node -nodeConfig condifg.json -log node-log.txt &>/dev/null & 

如果我添加applicationName或任何其他功能，就会得到错误：

      }
    ]
  }
