Testing for FactoryGirl Results - ruby-on-rails

Question

I'm trying to test to see if the items the array exist after I create the factory.
spec/models/thing_spec.rb
require 'rails_helper'
RSpec.describe Thing, :type => :model do
let(:thing) { Array.new(3) {FactoryGirl.create(:thing) } }
it "should sort the items in order" do
expect(thing).to include(ordering:1, ordering:2, ordering:3)
end
end
spec/factories/things.rb
FactoryGirl.define do
factory :thing, :class => 'Thing' do
name "item_name"
sequence(:ordering)
end
end
Below are the results that I received.
results
1) Things should be sorted in order
Failure/Error: expect(thing).to include(ordering:1, ordering:2, ordering:3)
expected [#<Thing id: 1, name: "item_name", create_date: "2014-11-07 04:18:17", modified_date: "2014-11-14 04:18:17", ordering: 1>, #<Thing id: 2, name: "item_name", create_date: "2014-11-07 04:18:17", modified_date: "2014-11-14 04:18:17", ordering: 2>, #<Thing id: 3, name: "item_name", create_date: "2014-11-07 04:18:17", modified_date: "2014-11-14 04:18:17", ordering: 3>] to include {:ordering => 2}

Answer 1

You can't do it this way. You'll have to check each record individually like this
it "should sort the items in order" do
expect(thing[0].ordering).to eq(1)
expect(thing[1].ordering).to eq(2)
expect(thing[2].ordering).to eq(3)
end
Or do something like this:
it "should sort the items in order" do
expect(thing.map(&:ordering)).to eq([1, 2, 3])
end
You can only use include to check if the array includes an element as a whole, like this:
expect(thing).to include(thing[0])
