Save and restore cookies of capybara session

Add this line to your application's Gemfile:

gem 'capybara-sessionkeeper'

And then execute:

$ bundle

Or install it yourself as:

$ gem install capybara-sessionkeeper

Require with capybara

require "capybara"
require "capybara/sessionkeeper"

[Recommended] Chrome driver is supported.
Install chromedriver

Capybara.register_driver :chrome do |app|
  Capybara::Selenium::Driver.new(app, browser: :chrome)
end

Firefox(:selenium option) may not work.
Install geckodriver

session = Capybara::Session.new(:selenium)

session will be equivalent to page in the system test.

It follows Capybara.save_path.

session = Capybara::Session.new(:chrome)
session.visit 'https://github.com/'
path = session.save_cookies

Save cookie file with specified file name.

session.save_cookies('user1.cookies.txt')

You have to visit the site which you are trying to restore cookie beforehand.
Otherwise, you will get error.

session = Capybara::Session.new(:chrome)
session.visit 'https://github.com/'
cookies = session.restore_cookies

Restore cookie file with specified file name.

session.restore_cookies(File.join(Capybara.save_path, 'user1.cookies.txt'))

Save cookie to yaml string (serialization to yaml).

yaml_str = session.cookies_to_yaml

Restore cookie from yaml string (deserialization from yaml).

session.restore_cookies_from_data(yaml_str, format: 'yaml')

session.driver.browser.manage.all_cookies

On restoring cookies, this gem ignores Selenium::WebDriver::Error::InvalidCookieDomainError.
If you repeat save_cookies and restore_cookies in a single file, you could lose some cookies of domains you haven't visited.

This behavior can be changed in the future.

Some use cases are,
Save/Restore cookies by users/use cases/sites.
You can switch signed-in users easily.
You don't need to sign in every time.
You just need to sign in once(or occasionally) and save/restore cookies.
