What's the best way to test delayed_job chains with rSpec?

Question

Currently when I have a delayed method in my code like the following:

CommentMailer.delay.deliver_comments(@comment, true)

I write something li

Answer 1

We can just have one more line in the before block as following:

CommentMailer.stub(:delay).and_return(CommentMailer)

Then you then can have the normal mock check as following:

CommentMailer.should_receive(:deliver_comments).with(comment, true)

Answer 2

describe '#perform' do
    subject do
      Delayed::Worker.delay_jobs = false
      proc { worker.perform() }
    end

    it { is_expected.to change { ActionMailer::Base.deliveries.length }.by(2) }
  end

Set delayed job as false and u can test it like simple

Here are some discussions about chaining methods in rSpec that I found helpful:
