Rails + Cucumber/Capybara: How to set/retrieve cookies in tests?

Question

I\'m implementing a lazy login feature. My cucumber feature should describe it:

    Feature: User log in

        Scenario: Lazy login
            Given I didn\'         


        

Answer 1

I needed just to test the cookie values

Inspiration taken from https://collectiveidea.com/blog/archives/2012/01/05/capybara-cucumber-and-how-the-cookie-crumbles

and ported to Rails 5.x

Create features/support/cookies.rb

With content

module Capybara
  class Session
    def cookies
      @cookies ||= ActionDispatch::Request.new(Rails.application.env_config.deep_dup).cookie_jar
    end
  end
end

Before do
  allow_any_instance_of(ActionDispatch::Request).to receive(:cookie_jar).and_return(page.cookies)
  allow_any_instance_of(ActionDispatch::Request).to receive(:cookies).and_return(page.cookies)
end

Then the step for testing

Then('is set cookie {string} with value {string}') do |cookie, value|
  expect(page.cookies.signed[cookie]).to eq value
end
