How do I test whether my controller rendered the right layout on Rails 3?

Question

Controller code:

class BooksController < ApplicationController
  def index
    @books = Book.all
    respond_to do |format|
      format.html do
        r         


        

Answer 1

For RSpec 3:

expect(response).to render_template(:new)   # wraps assert_template
