Feature: Cookies
There are different ways to make assertions on cookies from controller specs,
but we recommend using the `cookies` method as set out below.
You can use strings or symbols to fetch or set your cookies because the `cookies`
method supports indifferent access.
Scenario: Testing cookie's value cleared in controller
Given a file named "spec/controllers/application_controller_spec.rb" with:
"""ruby
require "rails_helper"
RSpec.describe ApplicationController, type: :controller do
controller do
def clear_cookie
cookies.delete(:user_name)
head :ok
end
end
before do
routes.draw { get "clear_cookie" => "anonymous#clear_cookie" }
end
it "clear cookie's value 'user_name'" do
cookies[:user_name] = "Sam"
get :clear_cookie
expect(cookies[:user_name]).to eq nil
end
end
"""
When I run `rspec spec`
Then the example should pass
