Testing for FactoryGirl Results

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)

Does it work? What's your question? Are you getting an exception? — Nick Veys

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])
