rspec テストが通らない

Question

下記のテストが通りません。
お詳しい方よろしくお願いいたします。

class Potepan::ProductsController < ApplicationController
def show
@product = Spree::Product.find(params[:id])
@related_products = Spree::Product.includes_price_image.same_taxon(@product).limit(5)
end
end

require 'rails_helper'

RSpec.describe Potepan::ProductsController, type: :controller do
describe 'show action' do
let(:taxonomy) { create(:taxonomy, name: 'taxonomy') }
let(:taxon) { create(:taxon, name: 'taxon', taxonomy: taxonomy, parent_id: taxonomy.root.id) }
let!(:product) { create(:product) }
let!(:related_products) { create_list(:product, 3, taxons: [taxon]) }

before do
  get :show, params: { id: product.id }
end


it 'has the proper http status' do
  expect(response.status).to eq 200
end


it 'show page' do
  expect(response).to render_template :show
end


it 'assigns @product' do
  expect(assigns(:product)).to eq product
end

it 'assigns @related_products' do
  expect(assigns(:related_products)).to match_array related_products
end

end
end

1. Potepan::ProductsController show action assigns @related_products
   Failure/Error: expect(assigns(:related_products)).to match_array related_products

   expected collection contained:  [#<Spree::Product id: 446, name: "Product #10 - 3677", description: "As seen on

actual collection contained: []
the missing elements were: [#<Spree::Product id: 446, name: "Product #10 - 3677", description: "As seen on

Answer 1

[]とか()はどっちでもよさそうでした。

期待される値

[#<Spree::Product id: 576, name: "Product #20 - 5006", description: "As seen on TV!", available_on: "...at: "2019-01-08 04:48:35", updated_at: "2019-01-08 04:48:35", promotionable: true, meta_title: nil>]

取得した値

[]

不足分

[#<Spree::Product id: 576, name: "Product #20 - 5006", description: "As seen on TV!", available_on: "...at: "2019-01-08 04:48:35", updated_at: "2019-01-08 04:48:35", promotionable: true, meta_title: nil>]

となってるのでプロダクトコードのインスタンス変数が空の配列になってるのではないでしょうか。

ご指摘の通り変更したのですがエラー内容は変わりませんでした。。。

it 'assigns @related_products' do
expect(assigns[:related_products]).to match_array related_products
end

Failure/Error: expect(assigns[:related_products]).to match_array related_products
