setting up cookies value

[Javix]

I'm coming back to the question regarding how to set up cookies values and read in RSpec controllers spec.

So following the Michael Hartl's Rails Tutorial, I tries to write a controller spec. Michael still uses 'the old' way and put controllers specs in requests folder and requires Capybara in spec_helper:

#config.include Capybara::DSL

I commented the above line as Capybara DSL will be used in features specs and will be loaded without problems.

So, I'd like just to set in some way cookies.permanent and do it in a separate module (spec/support:/login_macros.rb):

module LoginMacros

  def set_admin_session(admin)

    cookies.permanent['remember_token'] = admin.remember_token

  end

end

Then I included the module in spec_helper:

config.include LoginMacros

In my ClientsControllerSpec:

describe ClientsController do

  let(:admin) { create(:admin) }

  before { set_admin_session(admin) }

  describe 'GET #index' do

    it "populates an array of all clients" do

      clients = []

      3.times do

        clients << create(:client)

      end

      get :index

      expect(assigns(:clients)).to match_array(clients)

    end

  end 

end

ClientController:

class ClientsController < ApplicationController

  before_action :signed_in_user

  def index

    @clients = Client.paginate(page: params[:page])

  end

end

Here is 'signed_in_user' method in SessionsHelper:

module SessionsHelper

  def sign_in(user)

    remember_token = Admin.new_remember_token

    cookies.permanent[:remember_token] = remember_token

    user.update_attribute(:remember_token, Admin.digest(remember_token))

    self.current_user = user

  end

  def signed_in_user

    unless signed_in?

      store_location

      redirect_to signin_path, notice: t(:sign_in_required)

    end

  end

end

Here are the errors when running the specs:

ClientsController

  GET #index

    populates an array of all clients (FAILED - 1)

    renders the :index template (FAILED - 2)

Failures:

  1) ClientsController GET #index populates an array of all clients

     Failure/Error: expect(assigns(:clients)).to match_array(clients)

       expected an array, actual collection was nil

     # ./spec/controllers/clients_controller_spec.rb:16:in `block (3 levels) in <top (required)>'

  2) ClientsController GET #index renders the :index template

     Failure/Error: expect(response).to render_template :index

       expecting <"index"> but rendering with <[]>

     # ./spec/controllers/clients_controller_spec.rb:21:in `block (3 levels) in <top (required)>'

What is wrong here ? Why cookies are not set correctly ?

Thank you.

Found WHY it did not work.

I had to just sign in the admin user in my LoginMacros and include the corresponding helper (SessionsHelper):

include SessionsHelper

module LoginMacros

  def set_admin_session(admin)

    sign_in(admin)

  end

end

In ClientsControllerSpec :

require 'spec_helper'

describe ClientsController do

  let(:admin) { create(:admin) }

  before { set_admin_session(admin) }

  describe 'GET #index' do

    it "populates an array of all clients" do

      clients = []

      3.times do

        clients << create(:client)

      end

      get :index

      expect(assigns(:clients)).to match_array(clients)

    end

    it "renders the :index template" do

      get :index

      expect(response).to render_template :index

    end

   end

Hope this helps.

Even better, correct me if I'm wrong.

No need to add an additional hook (LoginMacros module) because SessionsHelper beign included in my ApplicationController, is automatically accessible in controller specs.

It means that I culd just call SessionsHelper 'sign_in method directly in my ClientControllerSpec:

require 'spec_helper'

describe ClientsController do

  let(:admin) { create(:admin) }

  before { sign_in(admin) }

...

end

and remove the include of LoginMacros module in spec_helper config blolck.

Voilà :)

Sorry , it was a little bit wrong.

I had to add an include into spec/support/utilities.rb file:

include SessionsHelper

to make it work.
