rspec - Ruby on Rails - Adding user in test case -

i new unit testing , trying wrap head around it. situation have article form user can enter title , description , on clicking create article article should created logged in user can perform operation need test this.

since new thinking,

1. i create user first
2. save session thats how system checks if user logged in (but thinking not browser logic might not work), how submit form logged in user?

here try

require 'rails_helper'      rspec.feature 'adding article'       scenario 'allow user add article'         @user = user.create(:email => "saadia1@clickteck.com", :password => 'password', :username => 'saadia1')         session[:user_id] = @user.id          visit new_article_path          # @article = article.user.to eql(@user = user.find_by(id: 6))         fill_in "title", with: "my title"         fill_in "description", with: "my description"           click_on("create article")          expect(page).to have_content("my title")         expect(page).to have_content("my description")        end     end 

when run command rspec spec/features/add_article_spec.rb

i see

failures:

1) adding article allow user add article failure/error: session[:user_id] = @user.id

 nameerror:    undefined local variable or method `session' #<rspec::examplegroups::addingarticle:0x007f89285e32e8>  # ./spec/features/add_article_spec.rb:6:in `block (2 levels) in <top (required)>'

so question how add article logged in user? appreciate on this.
