undefined local variable or method `streams' about action-cable-testing

[palkan]

using Rails 6.0.2.1

Then you're using Rails' built-in Action Cable testing tools under the hood.
streams method has been deprecated and wasn't included into Rails version.

Use have_stream matcher instead.

thanks for your response. I'm actually using rspec for the testing

➜ rspec -v
RSpec 3.9
  - rspec-core 3.9.1
  - rspec-expectations 3.9.1
  - rspec-mocks 3.9.1
  - rspec-rails 4.0.0
  - rspec-support 3.9.2

But maybe because I'm using Rails 6 it won't work?

I attempted using have_stream(msg) but that is not working either. Guess I'll do some more digging

RSpec wraps the API provided by Rails

action-cable-testing/lib/rspec/rails/example/channel_example_group.rb

Line 25 in f1a0b23

include ActionCable::Channel::TestCase::Behavior

and defines some additional helpers

action-cable-testing/lib/rspec/rails/example/channel_example_group.rb

Lines 42 to 62 in f1a0b23

	def have_rejected_connection
	raise_error(::ActionCable::Connection::Authorization::UnauthorizedError)
	end
	def have_streams
	check_subscribed!
	RSpec::Rails::Matchers::ActionCable::HaveStream.new
	end
	def have_stream_from(stream)
	check_subscribed!
	RSpec::Rails::Matchers::ActionCable::HaveStream.new(stream)
	end
	def have_stream_for(object)
	check_subscribed!
	RSpec::Rails::Matchers::ActionCable::HaveStream.new(broadcasting_for(object))
	end

.

unfortunately that does not allow me to test the modified data from redis that is then being sent to the consumer, that really only verifies the key it's listening to but not the data object being sent.

expect(streams).to include(the_object_being_sent_to_consumer) would be ideal

[palkan]

You should use have_broadcasted_to matcher for that.
