Upgraded Shoulda from 2 to 3, and now my custom extended methods don't seem to be working

Question

My methods :

      Shoulda::Context.send(:include, Module.new do
        def when_reminder_sent(n, &blk)
          context "when reminder #{n} was sent" do
            setup { subject.free_trial_notice_sent = n }
            blk.bind(self).call
          end
        end
        def when_payment_was_received(&blk)
          context 'when payment has been received' do
            setup { subject.last_payment_received_at = 1.day.ago }
            blk.bind(self).call
          end
        end
      end)

It injects and returns true. So I know its in there. But when I do :

      context 'on day 15' do
        when_reminder_sent(15) { should('be nil') { assert_nil subject.reminder_to_send }}

It returns :

 NoMethodError: undefined method `when_reminder_sent' for EnterpriseRegistrationTest:Class

Ah so I see its trying to use this method on my tested Model.. how can I ensure that it is using the method within its original Shoulda context?

Answer 1

So I just rewrote this and threw it at the beginning of the test. Evidently this module injection isn't properly coded for the upgrade.

Winning Answer

class MyMassiveObjectTest < ActiveSupport::TestCase

  def self.when_reminder_sent(n, &blk)
    context "when reminder #{n} was sent" do
      setup { subject.free_trial_notice_sent = n }
      blk.bind(self).call
    end
  end
  def self.when_payment_was_received(&blk)
    context 'when payment has been received' do
      setup { subject.last_payment_received_at = 1.day.ago }
      blk.bind(self).call
    end
  end
