How do I test the comments of the current_user in RSpec? - ruby-on-rails

Question

So I have a User that has_many :comments.
In my Comments#Index, I have this:
def index
#comments = current_user.comments
end
Inside my Rspec.config... block in rails_helper.rb I have this:
# Add Config info for Devise
config.include Devise::TestHelpers, type: :controller
My comments_controller_spec.rb looks like this:
describe 'GET #index' do
it "populates an array of comments that belong to a user" do
user = create(:user)
node = create(:node)
comment1 = create(:comment, node: node, user: user)
comment2 = create(:comment, node: node, user: user)
get :index, { node_id: node }
expect(assigns(:comments)).to match_array([comment1, comment2])
end
it "renders the :index template"
end
This is my Users.rb factory:
FactoryGirl.define do
factory :user do
association :family_tree
first_name { Faker::Name.first_name }
last_name { Faker::Name.last_name }
email { Faker::Internet.email }
password "password123"
password_confirmation "password123"
bio { Faker::Lorem.paragraph }
invitation_relation { Faker::Lorem.word }
# required if the Devise Confirmable module is used
confirmed_at Time.now
gender 1
end
end
This is my Comments factory:
FactoryGirl.define do
factory :comment do
association :node
message { Faker::Lorem.sentence }
factory :invalid_comment do
message nil
end
end
end
This is the error I am getting now:
Failure/Error: get :index, { node_id: node }
NoMethodError:
undefined method `comments' for nil:NilClass
Thoughts?

You need to sign in first:
describe 'GET #index' do
let(:user) { create(:user) }
let(:node) { create(:node) }
let(:comment1) { create(:comment, node: node, user: user) }
let(:comment2) { create(:comment, node: node, user: user) }
before do
#request.env["devise.mapping"] = Devise.mappings[:user]
sign_in user
end
it "populates an array of comments that belong to a user" do
get :index, { node_id: node }
expect(assigns(:comments)).to match_array [comment1, comment2]
end
end
You could also create a module in your spec/support directory with the following code:
module SpecAuthentication
def login_user
#request.env["devise.mapping"] = Devise.mappings[:user]
#user = FactoryGirl.create :user
sign_in #user
end
end
and include it in your RSpec.configure block:
config.include SpecAuthentication
Now you can call the login_user method in your specs:
describe 'GET #index' do
let(:node) { create(:node) }
let(:comment1) { create(:comment, node: node, user: #user) }
let(:comment2) { create(:comment, node: node, user: #user) }
before { login_user }
it "populates an array of comments that belong to a user" do
get :index, { node_id: node }
expect(assigns(:comments)).to match_array [comment1, comment2]
end
end
Update
Instead of including the module in the configure block in your spec/rails_helper.rb file, you could also add a configure block in the support file (spec/support/devise.rb) itself:
module SpecAuthorization
...
end
RSpec.configure do |config|
config.include SpecAuthorization
end
