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

Answer 1

Anyone using rspec +3.4 and ActiveJob to send async emails, try with:

expect {
  post :create, params
}.to have_enqueued_job.on_queue('mailers')
