Module: Devise::Test::ControllerHelpers

Extended by:
ActiveSupport::Concern
Defined in:
lib/devise/test/controller_helpers.rb

Overview

‘Devise::Test::ControllerHelpers` provides a facility to test controllers in isolation when using `ActionController::TestCase` allowing you to quickly sign_in or sign_out a user. Do not use `Devise::Test::ControllerHelpers` in integration tests.

Examples

class PostsTest < ActionController::TestCase
  include Devise::Test::ControllerHelpers

  test 'authenticated users can GET index' do
     users(:bob)

    get :index
    assert_response :success
  end
end

Important: you should not test Warden specific behavior (like callbacks) using ‘Devise::Test::ControllerHelpers` since it is a stub of the actual behavior. Such callbacks should be tested in your integration suite instead.

    Devise.deprecator.warn <<-DEPRECATION.strip_heredoc
      [Devise] sign_in(:#{scope}, resource) on controller tests is deprecated and will be removed from Devise.
      Please use sign_in(resource, scope: :#{scope}) instead.

  scope ||= Devise::Mapping.find_scope!(resource)

  warden.instance_variable_get(:@users).delete(scope)
  warden.session_serializer.store(resource, scope)
end

#sign_out(resource_or_scope) ⇒ Object

Sign out a given resource or scope by calling logout on Warden. This method bypass any warden logout callback.
