测试Sidekiq / ActiveJob - 在ActiveJob中工作但不在Sidekiq工作

Question

I monkey patched my user class (backed by devise) to use ActiveJob like so:

class User < ActiveRecord::Base
  # Omitted

  def send_devise_notification(notification, *args)
    devise_mailer.send(notification, self, *args).deliver_later
  end
end

I tried testing this with the following test:

class UserTest < ActiveSupport::TestCase
  include ActiveJob::TestHelper

  def setup
    @user = User.new(email: 'example@gmail.com', password: 'password',
                     password_confirmation: 'password')
  end

  test 'send_devise_notification queues into activejob' do
    @user.save
    assert_equal enqueued_jobs.size, 1 # This test passes
    assert_equal Sidekiq::Extensions::DelayedMailer.jobs.size, 1 # This test fails
  end

log/test.log looks like this:

bin/rails c --environment test

irb(main):004:0> Rails.application.config.active_job.queue_adapter
=> :sidekiq

My Procfile looks like this:

web: bin/rails s
redis: redis-server
worker: bundle exec sidekiq -q default -q mailers

Anyone have any ideas?

Answer 1

ActiveJob::TestHelper doesn't actually pass the job to the adapter. If you remove it, it'll be an instance of ActiveJob::QueueAdapters::SidekiqAdapter::JobWrapper .

Answer 2

In testing the default adapter is a TestAdapter (see in your logs: [ActiveJob] Enqueued ActionMailer::DeliveryJob (Job ID: 9730d5a8-5dd4-4334-8290-e4e8e554715e) to Test(mailers) with arguments...).

enqueued_jobs and other helpers provided by ActiveJob::TestHelper are querying the TestAdapter and only works if you are using the TestAdapter in testing.

So your first test passes as jobs are handled by the TestAdapter but your 2nd test won't pass as the jobs from the TestAdapter will never reach Sidekiq.
