Testing Rails ActionCable Channel

I followed along with the Online user tracking with ActionCable and was able to get it all working. I replicated a similar channel in another app and again it works great, however when I came to test the channel I hit a problem.

The problem:
Inside the the 'subscribed' method of the channel I am using the same 'ActionCable.serve.pubsub.redis_connection_for_subscriptions ...' as in the Online user tracking, this works fine in development, but when it comes to testing I get the following error;

NoMethodError: undefined methodredis_connection_for_subcsriptions' for #ActionCable::SubscriptionAdapter::Test:0x00007fbd5969d3e0`

I have dug around to try and figure out what is causing this and why but have not had any luck so far. Has anyone seen this error when working with/testing action cable channels, and how did you fix it ?

Thanks in advance

Did you figure out how to stub this? I've been trying to write some tests for this functionality as well and can not figure this out.

It sounds like you're facing challenges with ActionCable while testing your channel. The 'NoMethodError' can often stem from the testing environment not replicating the development setup. As for troubleshooting, ensure your test framework mimics the configuration accurately. It can be as frustrating as losing in the Retro bowl. Have you reviewed the setup closely or consulted documentation? Many developers encounter similar errors and resolve them with tweaks.
