Rails 6: undefined method `stub_connection' about action-cable-testing

[palkan]

Thanks for the report!

We plan to add RSpec support for Rails 6 soon (right after #46).

For now you can try the following:

# do not load the whole gem by default
gem "action-cable-testing", require: false

In your rails_helper.rb, after require "action_cable/testing/rspec" add the following (see https://github.com/palkan/action-cable-testing/pull/46/files#diff-fe8e12e25dcfdac5a034c51ff1cf1998R24):

RSpec::Rails::ChannelExampleGroup.include ActionCable::Connection::TestCase::Behavior

Hope that would help.

@palkan Thanks for the quick response! I ended up with this:

Bundler could not find compatible versions for gem "actioncable":
  In snapshot (Gemfile.lock):
    actioncable (= 6.0.0.beta1)

  In Gemfile:
    action-cable-testing (~> 0.4) was resolved to 0.4.0, which depends on
      actioncable (~> 5.0)

    rails (~> 6.0.0.beta1) was resolved to 6.0.0.beta1, which depends on
      actioncable (= 6.0.0.beta1)

Which is totally fine, obviously we need the rest of the Rails ecosystem to catch up. I've got a few other gems that aren't compatible as well. I will just sit tight and wait for things to progress.
