Haroon,

I haven't seen this when the session just stays open (although I've never left them open for more than a couple of hours). I have seen this when the test itself errors or fails. In this case the RC seems to lose connection to the hub (although it doesn't get unregistered). I was never able to figure out a way around that behavior; in fact, that is the number one reason I felt at the time that Selenium Grid was simply not ready for a large-scale deployment.

In your situation I would take a couple of tacks:
1. make your tests as short as possible. In general I think this is a good idea. Long tests GUI tests strung together tend to be rather brittle and also tend to show misleading errors (test failures caused by an unseen failure far earlier).
2. Run a wireshark trace (or tcpdump or flavor of your choosing) on the hub and see if there's a timeout or something you're hitting. It's possible you've got network or pingback problems and it's worth looking.

If we are using the same session for too long, selenium hub seems to stop communicating with the RCs. Did you find any solution for this?

Anon Mar 20:

Take a look in the rake file where I'm calling Rake::Task["test:selenium"]. You should be able to take that out and replace it with your method of calling the selenium tests.

Thanks a lot,

But I have a question. I've already written my .rsel file and it works. I call it like this rake test:acceptance my_file.rsel. I would like to pass to the file a parameter to precise wich product to test. How can I do. Thanks.

Peter - good luck! This has been one of those projects that seemed simple but had vast numbers of devils in the details (my least favorite so far is Selenium's tendency to simply stop communicating between the hub and a remote control - I still haven't solved that one yet).

So far I've only got the one rake file doing the work (plus the init script and whatnot, which are specific to my OS). I hope to have another update soon on this one. And thanks for the words of encouragement!

Hey Catherine,

We appear to be on the same Selenium-Grid-Rails trajectory!

Could you post more of your rake files and/or email me offline?

Thanks for your info so far... great posts!
