title: Delayed Job not processed in rspec
body: <p>I am trying to run rspecs for a custom delayed job (GetPage::GetPageJob), but I have a problem.</p>
  
  <p>When I run them, the jobs are well enqueued (that is to say, well inserted in the delayed_jobs table), but they are not processed by the job worker.
  Indeed, after launching "rake jobs:work RAILS_ENV=test" in a first terminal, and after running the specs in a second terminal, I don't see any output from the job worker in the first terminal.</p>
  
  <p>On the other hand, the jobs are well processed if I enqueue them via "script/console test".
  So I'm a bit confused.</p>
  
  <p>With both the specs and the script/console, the line I use to enqueue my jobs is :</p>
  
  <pre><code>Delayed::Job.enqueue GetPage::GetPageJob.new("http://cnn.com")
  </code></pre>
  
  <p>Any idea ?</p>
