testing email gets sent in cucumber

Question

I have a list of stories assigned to me in Cucumber, one of them being "Then the user should receive a confirmation email". I think testing that the user receives it is beyond the power of the application, but how can I test that an email had just been sent?

Answer 1

You can use this step definition :

Then "the user should receive a confirmation email" do
  # this will get the first email, so we can check the email headers and body.
  email = ActionMailer::Base.deliveries.first
  email.from.should == "[email protected]"
  email.to.should == @user.email
  email.body.should include("some key word or something....")
end

Tested with Rails 3.2

Answer 2

email_spec + action_mailer_cache_delivery gems are your friends for doing this
