Save and restore cookies and session with capybara and apparition

code.rb

# I have not deeply researched the best way of doing this. This is just one way.
# Made this gist because there was no google result for this exact question so I had to dive into the code instead.

# Saving
cookies = browser.driver.cookies.instance_variable_get(:@browser).get_raw_cookies.map { |c| c.instance_variable_get(:@attributes) }
cookies_json = cookies.to_json

# Restoring
cookies = JSON.parse(cookies_json)
cookies.each do |c| 
  browser.driver.set_cookie(c.fetch("name"), c.fetch("value"), c.except("name", "value").symbolize_keys)
end
