List The Enqueued Jobs

Many Rails apps need to delegate work to jobs that can be performed at a later time. Both unit and integration testing can benefit from asserting about the jobs that get enqueued as part of certain methods and workflows. Rails provides a handy helper method for checking out the set of enqueued jobs at any given time.

The enqueued_jobs method will provide a store of all the currently enqueued jobs.

It provides a number of pieces of information about each job. One way to use the information is like so:

describe '#do_thing' do
  it 'enqueues a job to do a thing later' do
    Processor.do_thing(arg1, arg2)
    expect(enqueued_jobs.map { |job| job[:job] }).to match_array([
      LongProcessJob,
      SendEmailsJob
    ])
  end
end

To use this in your Rails project, just enable the adapter in your test configuration file:

Rails.application.config.active_job.queue_adapter = :test
