Q:How to test ActionMailer deliver_later with Turnip,capybara and Gherkin

Question

def deliver_mail
  ServiceMailer.activation().deliver_later
end

deliver_mail method is called from some controller.

I want to test like below - feature test using cucumber and capybara.

step 'push next button' do find("input.submit").click end

Feature: Sending a mail to user
  Scenario: mail to a user
    When I push next button
    Then mail should be sent to a user

actually, when 'push next button' is pushed, mail is sent by deliver_mail method.

when I use deliver_now instead of deliver_later, I can test the code above.

but after I change deliver_now to deliver_later, I can not test.

so I referenced below.

I tried to include 'ActiveJob::TestHelper' like 'include ActiveJob::TestHelper' in spec file.

and i modified step file like this.

step 'push next button' do
 　perform_enqueued_jobs do
    find("input.submit").click
 　end
end

but still doesn't work.

any hint and advice please.

So how do you test that mail has been sent? Show us code from your test with `expect` statement. — P. Boro, Oct 11 '18 at 06:33

I am using Delayed::Job for sending emails in a background, so when I test sending emails, I have two separate kinds of tests:

1) rspec - to check email body (in general, the method inside mailer) and sending the email itself

2) cucumber - to check if the email job was queued

In cucumber, I have the following code:

Then(/^A welcome email will be sent$/) do
  expect(Delayed::Job.count).to eq(1)
end

I think there is no need to check anything else from the cucumber.

I would recommend not delaying jobs in test, and then checking the results of whatever DJ was supposed to run.

# rails_helper.rb

Delayed::Worker.delay_jobs = false
