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/1.2.1/file/README.rdoc#Testing_In_Isolation
But it doesn't work, because I pass an instance of the model-object to the delivery-method and the instance is saved before the delivery.
I tried to create an other instance of the model-object, but then the id isn't the same.
My controller-method looks like this:
def create
@params = params[:reservation]
@reservation = Reservation.new(@params)
if @reservation.save
ReservationMailer.confirm_email(@reservation).deliver
redirect_to success_path
else
@title = "Reservation"
render 'new'
end
end
Do you have any idea to solve this?
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.
