For the sake of being complete, with Rails 5 and RSpec I have run into similar issues when using the latest helpers, as they need to be set explicitly with the type when not used as a superclass.

So if you find yourself receiving there errors in your model tests there's a pretty good chance the type is not set.

Here's what I use in the spec_helper:

  config.include Devise::Test::ControllerHelpers, type: :controller
  config.include Devise::Test::ControllerHelpers, type: :view
  config.include Devise::Test::IntegrationHelpers, type: :feature

I know that the docs do mention this, but there are times when you may run across an older blog that gives you an older approach, or upgrading from an older setup, and next thing you know this happens.
