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

Assuming your test environment is set up in the usual fashion (that is, you have config.action_mailer.delivery_method = :test), then delivered emails are inserted into the global array ActionMailer::Base.deliveries as Mail::Message instances. You can read that from your test case and ensure the email is as expected. See here.
