NoMethodError: in Rspec - ruby-on-rails

Question

I'm currently doing rspec testing on two files and I got these failures regarding undefined methods. I need more calcification on how to exactly fixes these errors,Thanks!
Failures:
1) FavoritesController#create creates a favorite for the current user and specified post
Failure/Error: #post = create(:post)
NoMethodError:
undefined method `create' for #<RSpec::ExampleGroups::FavoritesController::Create:0x007fdabc84f7f8>
# /Users/bryanporras/.rvm/gems/ruby-2.2.1/gems/actionpack-4.2.1/lib/action_dispatch/testing/assertions/routing.rb:171:in `method_missing'
# ./spec/controllers/favorites_controller_spec.rb:8:in `block (2 levels) in <top (required)>'
2) FavoritesController#destroy destroys the favorite for the current user and post

Failed examples:

rspec ./spec/models/vote_spec.rb:24 # Vote after_save calls `Post#update_rank` after save
This is the favorites_controller_spec.rb file:
require 'rails_helper'
describe FavoritesController do
include Devise::TestHelpers
before do
#post = create(:post)
#user = create(:user)
sign_in #user
end
describe '#create' do
it "creates a favorite for the current user and specified post" do
expect( #user.favorites.find_by(post_id: #post.id) ).to be_nil
post :create, { post_id: #post.id }
expect( #user.favorites.find_by(post_id: #post.id) ).not_to be_nil
end
end
describe '#destroy' do
it "destroys the favorite for the current user and post" do
favorite = #user.favorites.where(post: #post).create
expect( #user.favorites.find_by(post_id: #post.id) ).not_to be_nil
delete :destroy, { post_id: #post.id, id: favorite.id }
expect( #user.favorites.find_by(post_id: #post.id) ).to be_nil
end
end
end
and this is the votes_controller_spec.rb file:
require 'rails_helper'
describe VotesController do
include TestFactories
describe '#up_vote' do
it "adds an up-vote to the post" do
request.env["HTTP_REFERER"] = '/'
#user = authenticated_user
#post = associated_post
sign_in #user
expect {
post( :up_vote, post_id: #post.id )
}.to change{ #post.up_votes }.by 1
end
end
end

Check if you have config.include FactoryGirl::Syntax::Methods inside rails_helper.rb
If you have above line in rails_helper.rb file you can always use FactoryGirl.create :user
You didn't probably include include Devise::TestHelpers in specs for VotesController that's why it does not see sign_in method
