[selenium-users] Need help with Selenium Grid with RobotFramework

Hi All,

I am using RobotFramework for automation testing.

I am running my test suites in parallel using node and specifying that node
in the suite setup.

Lets say one of my suite is having more testcases than other suites.
Execution goes on, on the respective node and other nodes are ideal.

Is it possible instead of configuring node in each suite, I give hub url
and then hub will distribute the test on available nodes.

I tried to give hub url but got following error:

WebDriverException: Message: Session [(null externalkey)] not available and
is not among the last 1000 terminated sessions.
Active sessions are[]

Sachin,

I didnt quite understand your problem statement. Would it be possible for
you to please help elaborate with some code samples on what you are trying
to figure out ?

Thanks & Regards

So basically you have just setup the Grid but not really using it. You
_must_ provide the HUB IP in your remote webdriver and not Node IP. If you
are using node IP you are just doing remote execution on some other machine.

You should leave it on Hub to decide on which node it needs to execute the
script

Hi Guys,

Thanks for your reply.

My setup is as follows:

1. I have setup a hub
2. Under that hub, I have configured 5 nodes with max of 3 instances of
browser
3. In my test suites I am giving hub url
4. I am running my test suites in parallel

My assumption is that, when testsuites run in parallel all requests will be
sent to hub and hub will distribute within available nodes.

But it didn't distribute and gets above mentioned error. If I manually
configure node for each test suite then it works fine, just not working
with hub

Thanks & Regards,
Sachin Nikam

Earlier I was giving http://172.16.4.201:4444/wd/hub

I changed it to http://172.16.4.201:4444/wd/hub and my problem solved.

Hi Sachin,

What was the actual fix here?
From your statement I can see the same url:
http://172.16.4.201:4444/wd/hub
http://172.16.4.201:4444/wd/hub

Thanks,
Alex
