Is the 'Travel' time helper not available in feature specs?

Question

I just tried to use Rails' time helper method travel in one of my feature specs:

scenario 'published_at allows to set a publishing date in the future' do
  magazine_article.update_attribute(:published_at, Time.now + 1.day)
  expect { visit magazine_article_path(magazine_article.magazine_category, magazine_article) }
         .to raise_error(ActiveRecord::RecordNotFound)

  travel 2.days do
    visit magazine_article_path(magazine_article.magazine_category, magazine_article)
    expect(page).to have_content('Super awesome article')
  end
end 

It's giving me this:

NoMethodError:
   undefined method `travel' for #<RSpec::ExampleGroups::MagazineArticles::AsUser::Viewing:0x007f84a7a95640>

What am I missing?

In order to use these helpers you have to include them into your tests.

You can do this by either including it into single test suite:

describe MyClass do
  include ActiveSupport::Testing::TimeHelpers
end

or globally:

RSpec.configure do |config|
  config.include ActiveSupport::Testing::TimeHelpers
end
