Make `_later` broadcasts happen synchronously in test environment

1

Hello,

I have a system spec for a page on my site. One button on this page kicks off a task that results in models being updated. Those updates appear asynchronously on the page via a broadcast on the model:

# app/models/effort.rb

class Effort < ApplicationRecord
  after_update_commit :broadcast_update

  private

  def broadcast_update
    broadcast_render_later_to event_group, partial: "efforts/updated", locals: { effort: self }
  end
end

# app/views/efforts/_updated.turbo_stream.erb

<%# locals: (effort:) %>

<%= turbo_stream.replace dom_id(effort, :roster_row),
                         partial: "efforts/entrant_for_roster",
                         locals: { effort: effort } %>

This works nicely. And if I use broadcast_render_to (synchronous) instead of broadcast_render_later_to (async), I can test the results like this:

RSpec.describe "set data status from the event group roster page", js: true do
  include ActionView::RecordIdentifier

  scenario "displays the resulting data status" do
    login_as steward, scope: :user
    visit roster_event_group_path(event_group)

    button = page.find_button("Set data status")
    button.click

    within("##{dom_id(effort, :roster_row)}") do
      expect(page).to have_content("good")
    end
  end
end

But I can’t figure out how to make this spec pass while using an async broadcast_render_later_to in the model.

Is there some way I can tell Rails to use a synchronous adapter when running in the test environment? Or any other way to test the result?

Thanks in advance!

Update: I figured this out, just needed to tell the :test adapter to actually perform the enqueued jobs. Here was my fix:

RSpec.describe "set data status from the event group roster page", js: true do
  include ActionView::RecordIdentifier
  include ActiveJob::TestHelper

  scenario "displays the resulting data status" do
    perform_enqueued_jobs do
      login_as steward, scope: :user
      visit roster_event_group_path(event_group)

      button = page.find_button("Set data status")
      button.click

      within("##{dom_id(effort, :roster_row)}") do
        expect(page).to have_content("good")
      end
    end
  end
end
