Rspec: test if method was called on an object inside a job? - ruby-on-rails

Question

I made a job to call a method if ended_at was less than today. For some reason I keep getting failures even if I throw a binding pry right at the moment it is about to break and manually call the method and it works fine. However, I still get a failure if I just let the spec test run on its own.
My job:
class RemoveOldEventsFromAlgoliaJob < ApplicationJob
queue_as :default
def perform
old_events = Event.where("ended_at < ?", Date.today)
old_events.each do |e|
e.remove_from_algolia
end
end
end
My method:
def remove_from_algolia
index = Algolia::Index.new(##ALGOLIA_INDEX_NAME)
index.delete_object(self.id)
end
My spec test:
require 'rails_helper'
RSpec.describe RemoveOldEventsFromAlgoliaJob, type: :job do
it "will remove old events from the index" do
ActiveJob::Base.queue_adapter = :test
event = FactoryGirl.create(:event, title: "EXPIRED EVENT", ended_at: 1.day.ago)
RemoveOldEventsFromAlgoliaJob.perform_now
expect(event).to receive(:remove_from_algolia)
end
end
RSpec output:
Failures:
1) d will remove old events from the index
Failure/Error: expect(event).to receive(:remove_from_algolia)

I can put a binding.pry inside my job during the spec test and call that method successfully:
4: def perform
5:
6: old_events = Event.where("ended_at < ?", Date.today)
7: old_events.each do |e|
=> 8: binding.pry
9: e.remove_from_algolia
10: end
11: end

Try using a stub for event instead of a real Event model:
require 'rails_helper'
RSpec.describe RemoveOldEventsFromAlgoliaJob, type: :job do
it "will remove old events from the index" do
ActiveJob::Base.queue_adapter = :test
event = double('event')
allow(Event).to receive(:where).and_return([event])
expect(event).to receive(:remove_from_algolia)
RemoveOldEventsFromAlgoliaJob.perform_now
end
end
