I’ve written an RSpec integration test. According to test.log, I can see that it has sent an email, but when I try to access the email using ActionMailer::Base.deliveries, it always shows it is empty.

I have read the other similar questions and tried everything. I’m stumped.

Here is the code using Capybara/RSpec:

it "should notify owner" do

  puts "Delivery method: #{ActionMailer::Base.delivery_method.inspect}"
  # This returns: ":test", which is correct

  # Get other guests to do the review
  @review = Review.last
  share_link = "http://#{@account.subdomain}.cozimo.local:#{Capybara.server_port}/review/#{@review.slug}"

  visit(share_link)

  fill_in "email", :with => @user1.email
  fill_in "password", :with => "foobar"

  click_button "Start Review"

  # Add a comment
  click_on "ice-global-note-button"
  find(:css, "#ice-global-note-panel > textarea.ui-corner-all").set "Foo"
  click_on "ice-global-note-submit-button"

  # Test is failing here. WTF? The array should not be empty
  ActionMailer::Base.deliveries.empty?.should be_false

  # Check that a notification email was sent to the owner
  open_email(@owner.email)
  current_email.should have_content "Hi #{@owner.first_name}"

end

As you can see above, config.action_mailer.delivery_method = :test

In test.log, it shows that the email really is sent!

    This is an integration test using Capybara and Selenium. Therefore, you have to wait for the application to actually send the mail before checking that it has sent it.

    Note – this solves the problem but is generally bad practice

    Add a sleep 1 to tell rspec to wait after triggering the send mail event. It then resumes by checking the ActionMailer::Base.deliveries array and passed.

    As mentioned, this is generally bad practice because it slows down tests.

    Better way

    Integration test shouldn’t test the mail is sent at all. Tests should be divided up into clear responsibilities for the class being tested. Therefore, we’d structure the tests differently so that we only test for the mail being sent in another class (a controller or resource test). We could also use expectations to check that the call to the mail method was actually made though it’s possible that we’d still get timing issues.
