Feature: `have_broadcasted_to` matcher
The `have_broadcasted_to` (also aliased as `broadcast_to`) matcher is used
to check if a message has been broadcasted to a given stream.
Background:
Given action cable testing is available
Scenario: Checking stream name
Given a file named "spec/models/broadcaster_spec.rb" with:
"""ruby
require "rails_helper"
RSpec.describe "broadcasting" do
it "matches with stream name" do
expect {
ActionCable.server.broadcast(
"notifications", { text: "Hello!" }
)
}.to have_broadcasted_to("notifications")
