How to test with RSpec if an email is delivered

Question

I\'d like to test if an email is delivered if I call a controller method with :post. I\'ll use email_spec so I tried this snipped here: http://rubydoc.info/gems/email_spec/1

I know I'm late to the party with this one, but for future Googlers...

I think a better solution to this problem is answered here

The previously accepted answer is testing the Mailer itself (inside the controller spec). All you should be testing for here is that the Mailer gets told to deliver something with the right parameters.

You can then test the Mailer elsewhere to make sure it responds to those parameters correctly.

ReservationMailer.should_receive(:confirm_email).with(an_instance_of(Reservation))
