Answer 1

MiniTest, Rails 4

This works for vanilla Rails 4 MiniTest

test\controllers\users_controller_test.rb

require 'test_helper'

class UsersControllerTest < ActionController::TestCase
  include Warden::Test::Helpers
  include Devise::Test::ControllerHelpers

  setup do
    # https://github.com/plataformatec/devise/wiki/How-To:-Test-with-Capybara
    # @user = users(:admin)
    # sign_in @user
  end

  teardown do
    Warden.test_reset!
  end

  test "login as admin" do
    @user = users :admin
    sign_in @user
    get :dashboard
    assert_redirected_to admin_dashboard_path
  end

end

Answer 2

In the spec_helper.rb add:

config.include Devise::Test::ControllerHelpers, :type => :controller

Answer 3

You could add the following to your rails_helper:

RSpec.configure do |config|
  config.include Devise::Test::ControllerHelpers, type: :controller
end

This will include Devise::Test::ControllerHelpers module in all :controller specs.
