ActionMailer::Base.deliveries array not being populated - ruby-on-rails

Question

I'm trying to run an rspec test.
You can see most of that code here.
Maybe it's relevant: CoRegEmailWorker.perform contains this:
ProvisionalUser.where("unsubscribed = false AND disabled = false AND (email_sent_count < ? OR email_sent_count is NULL) AND (last_email_sent <= ? OR last_email_sent IS NULL) AND sign_up_date IS NULL",
ProvisionalUser::EMAIL_COUNT_LIMIT, email_sending_interval.hours.ago).
each{ |user|
begin
user.send_email
rescue Exception => ex
logger.error ex
end
}
and ProvisionalUser has this method:
def send_email
self.email_sent_count = self.email_sent_count.nil? ? 1 : self.email_sent_count + 1
self.last_email_sent = DateTime.now
self.disabled = true if self.email_sent_count == EMAIL_COUNT_LIMIT
self.save!
ProvisionalUserNotifier.send_registration_invite(self.id).deliver
end
Finally, ProvisionalUserNotifier inherits from MailGunNotifier which inherits from ActionMailer.
The problem I'm having is that the deliveries array is not being populated. In my `config/environments/test.rb'. I have this:
config.action_mailer.perform_deliveries = true
config.action_mailer.delivery_method = :test
I'm not certain what else is needed here.
i've even gone so far as to try this:
require "spec_helper"
require "action_mailer"
describe "unsubscribe functionality" do
pu1 = ProvisionalUser.new
pu1.email = 'contact_me#test.com'
pu1.partner = 'partner'
pu1.first_name = 'joe'
pu1.save!
before(:each) do
ActionMailer::Base.delivery_method = :test
ActionMailer::Base.perform_deliveries = true
ActionMailer::Base.deliveries = []
end
it "should send emails to subscribed users only" do
unsubscribed_user = FactoryGirl.build(:unsubscribed_user)
unsubscribed_user.save!
subscribed_user = FactoryGirl.create(:subscribed_user)
CoRegEmailWorker.perform
ActionMailer::Base.deliveries.length.should == 1
ActionMailer::Base.deliveries.first.email.should =~ subscribed_user.email
#sent.first.email.should_not =~ unsubscribed_user.email
#sent.first.email.should =~ subscribed_user.email
end
def sent
ActionMailer::Base.deliveries
end
end

Answer 1

wow. that was really annoying. because the exception was being eaten, i wasn't seeing that I was missing a neccessary value for the subject of the email to work.
