devise with rspec test fails due to prevoius tests - ruby-on-rails

Question

i have used devise in rspec testing. this is my test
describe BooksController do
before(:all) do
#user = FactoryGirl.create(:user)
end
describe "GET index" do
it "shows list of current user books" do
sign_in #user
book = #user.books.create!(:title => "user")
get :index, {}
assigns(:books).should eq(#user.books)
end
end
describe "GET show" do
it "assigns the requested book as #book" do
sign_in #user
book = #user.books.create!(:title => "user")
visit_count = book.visits.to_i
get :show, {:id => book.to_param}
assigns(:book).should eq(book)
book = Book.find(book.id)
visit_count.should_not eq(book.visits)
end
end
describe "GET new" do
it "assigns a new book as #book" do
sign_in #user
get :new, {}
assigns(:book).should be_a_new(Book)
end
end
end
factory
FactoryGirl.define do
factory :user do
sequence(:email) { |n| "foo#{n}#example.com" }
password '12345678'
password_confirmation '12345678'
confirmed_at Time.now
end
end
book controller
class BooksController < ApplicationController
before_action :authenticate_user!, only: [:index, :edit, :update, :destroy, :new, :my_books, :add_wish_list]
# GET /books
# GET /books.json
def index
#books = current_user.books
end
# GET /books/1
# GET /books/1.json
def show
#book = Book.find(params[:id])
#book.book_visit_count
if(session["warden.user.user.key"].present?)
#book.book_visit_user(session["warden.user.user.key"][0][0])
end
end
# GET /books/new
def new
#book = Book.new
end
end
error
Failure/Error: assigns(:book).should be_a_new(Book)
expected nil to be a new Book(id: integer, title: string, author: string, isbn_10: string, isbn_13: string, edition: integer, print: integer, publication_year: integer, publication_month: string, condition: string, value: integer, status: boolean, stage: integer, description: text, visits: integer, user_id: integer, prefered_place: string, prefered_time: string, created_at: datetime, updated_at: datetime, rating: integer, image: string, publisher: string, goodreads_id: string)
# ./spec/controllers/books_controller_spec.rb:66:in `block (3 levels) in <top (required)>'
the problem is the third test "get new" fails when i run the test as a whole but passes when i run it individually. and also if i remove the before_authenticate! in controller then all test passes.
Again if i commented out the "assigns" in first two describe blocks then all tests pass again.
i am using rails 4.0.2 and rspec 2.14.7 , devise 3.2.2

Answer 1

The only thing I can figure is that your authenticate_user method is failing for users that have previously been authenticated. It's not affecting show because you don't have :show listed in your before_action. You could test this theory by requiring authentication for show as well and seeing if your second example starts failing for before(:all) as well.
