You know Show archive.org snapshot that Devise offers RSpec test helpers for controller specs. However, in request specs, they will not work.

Here is a solution for request specs, adapted from the Devise wiki Show archive.org snapshot . We will simply use Warden's test helpers -- you probably already load them for your Cucumber tests.

First, we define sign_in and sign_out methods. These will behave just like those you know from controller specs:

module DeviseRequestSpecHelpers

  include Warden::Test::Helpers

  def sign_in(resource_or_scope, resource = nil)
    resource ||= resource_or_scope
    scope = Devise::Mapping.find_scope!(resource_or_scope)
    login_as(resource, scope: scope)
  end

  def sign_out(resource_or_scope)
    scope = Devise::Mapping.find_scope!(resource_or_scope)
    logout(scope)
  end

end

Finally, load that module for request specs:

RSpec.configure do |config|
  config.include DeviseRequestSpecHelpers, type: :request
end

Done. You can now write request specs like this:

sign_in create(:user, name: 'John Doe')
visit root_path
expect(page).to include('John Doe')
