Rails/Rspec: Testing delayed_job mails

Question

Just wondering how to test that actionmailer requests are actually sent to the delayed_job que in rspec.

I would have assumed it was quite simple, but my delayed_job que

Answer 1

This thread is a bit old, but here is my go at it:

Create a function expect_jobs

def expect_jobs n, time = nil
  expect(Delayed::Job.count).to eq(n)
  Timecop.travel(time) unless time.nil?
  successes, failures = Delayed::Worker.new.work_off
  expect(successes).to eq(n)
  expect(failures).to eq(0)
  expect(Delayed::Job.count).to eq(0)
  Timecop.travel(Time.now) unless time.nil?
end

Then simply call it before checking if the callback has done its job. eg:

it "sends a chapter to the admin user" do
  post :chapter_to_user, { chapter: @book.chapters.first}
  expect_jobs(1)
  SubscribeMailer.should have(1).delivery
  SubscribeMailer.deliveries.should have(1).attachment
end

This seems to work on my side, and allows me to run both my delayed jobs and my methods.
