Hi,

I am trying to setup Selenium Grid4 with Hub running in a OpenShift Cluster and Nodes on separate Windows-VMs.

Hub is currently running and I have access to the grids webconsole but when I am starting a Node on my local maschine it fails to register.

Does someone how to a achieve that?

Thanks

Alex

Hi,

Can you share the command for registering the node?

When you are running node and hubs on different machines you will have to provide in node line the following parameters as well :

--publish-events tcp://HUB_IP:4442 --subscribe-events tcp://HUB_IP:4443

So when you start a new node on different machine it might looks this way
java -jar selenium-server-4.0.0.jar node --detect-drivers true --publish-events tcp://HUB_IP:4442 --subscribe-events tcp://HUB_IP:4443

Hi Nikolay,

Is there any example project or sample results of cmd commands for grid 4.

From official documentation it is hard to understand the output of CMD commands,

I'm also trying to setup node and hub on different machines but for checking the new grid I'm trying to register my node on same machine.

I used the command mentioned in official documentation

I'm able to register the hub and got below output

when I'm trying to register to hub from my node I'm seeing below output, my node is not registered as i cant see any node registered in my console

What is expected after sending registration event?

help is appreciated!!.

Regards,

Barnita

Selenium 4 commands are changed compared to 3, atleast for some scenarios

Yes I noticed, however i have used the latest command, the commands are working its just I'm not able to anticipate the output of next command.

previously with grid 3 i was able to register the node and hub on same machine, but now when I'm trying the same with grid 4 , the node is stuck at sending registration request.
