#connect_turbo_cable_stream_sources(**options, &block) ⇒ Object

Delay until every ‘<turbo-cable-stream-source>` element present in the page is ready to receive broadcasts

test "renders broadcasted Messages" do
  message = Message.new content: "Hello, from Action Cable"

  visit "/"
  click_link "All Messages"
  message.save! # execute server-side code to broadcast a Message

  assert_text message.content
end

By default, calls to #visit will wait for all ‘<turbo-cable-stream-source>` elements to connect. You can control this by modifying the config.turbo.test_connect_after_actions. For example, to wait after calls to #click_link, add the following to config/environments/test.rb:

# config/environments/test.rb
config.turbo.test_connect_after_actions << :click_link

To disable automatic connecting, set the configuration to []:

# config/environments/test.rb
config.turbo.test_connect_after_actions = []
