How to do test integration of features based on delayed jobs with cucumber?

Question

I want to test some features that needs delayed jobs to work, on cucumber. I have defined the following step:

Given /^jobs are being dispatched$/ do 
    Delayed::Worker.new.work_off
end

Right now, I am trying to test email notifications. So I have the following scenario:

Scenario: Receiving email when signing up   
      Given I am on the signup page
      And I fill in "user[email]" with "[email protected]" 
      And I fill in "user[password]" with "password"
      And I fill in "user[password_confirmation]" with "password"
      And I press "Sign up"
      Then I should be on the homepage
      Given jobs are being dispatched
      Then "[email protected]" should receive 1 emails

The should receive n emails step is defined by email_spec and is defined as:

Then /^(?:I|they|"([^"]*?)") should receive (an|no|\d+) emails?$/ do |address, amount|
  unread_emails_for(address).size.should == parse_email_count(amount)
end

So the test fails telling me that I am receiving 0 emails (the [email protected] is replaced by a real email in this test and I am not receiving anything). I suspect that the worker didn't really start. What should I check? By the way, when I test in development mode I really receive that email.

Thanks

Edit:

It looks like I am getting a SQLite3::BusyException:

SQLite3::BusyException: database is locked: INSERT INTO "delayed_jobs" ....

Now to investigate why and how I can get rid of that! Any idea? (besides moving my database to PostgreSQL or mySQL).

Edit: Ok, I moved to PostgreSQL from SQLite, the records are being inserted into Delayed::Job but the email tests fail.

The config/environments/test.rb file contains:

 config.action_mailer.delivery_method = :test
  config.action_mailer.perform_deliveries = true

  config.action_mailer.smtp_settings = {
     :address              => "smtp.gmail.com",
     :port                 => 587,
     :domain               => "mydomain.com",
     :user_name            => "[email protected]",
     :password             => "mypassword",
     :authentication       => "plain",
     :enable_starttls_auto => true
   }

  config.action_mailer.default_url_options = { :host => 'localhost:3000' }

Sorry, but the answer is to move off of sqlite. Delayed job locks the database so your app gets staved.
