RSpecの作成されたオブジェクト

Question

と等しくない記号を期待し、私はRSpecの持つcontrollのためのテストを書いた：

it "populates an array of books" do 
    book = FactoryGirl.create(:book) 
    get :index 
    expect(:books).to eql([book]) 
end 

books_controller.rbを

def index 
    @books = Book.all.order("created_at DESC") 
end 

books.rb

FactoryGirl.define do 
    factory :book do |f| 
    f.name { Faker::Book.title } 
    f.author { Faker::Book.author } 
    f.press { Faker::Book.publisher } 
    f.cover { fixture_file_upload(Rails.root.join('spec', 'photos', 'testcover.jpg'), 'image/png') } 
    end 
end 

ランビン/レーキ仕様では、結果は：

1) BooksController GET #index populates an array of books 
Failure/Error: expect(:books).to eql([book]) 

    expected: [#<Book id: 1, name: "The Waste Land", author: "谢靖琪", isbn: nil, press: "University of Chicago Press"...e: "image/png", cover_file_size: 104531, cover_updated_at: "2016-08-26 04:00:19", page_number: nil>] 
     got: :books 

    (compared using eql?)

これらは等しくありません。最初の期待された結果、「...」は略語であるようです。どうすれば修正できますか？私はあなたが何をしたいと思います

Answer 1

が

expect(assigns(:books)).to eq([book])
