I can't figure out the right way to test controller concern methods. What
kind of spec should it be, - controller or other?
Here is a concern I'd like to test:
#controllers/concerns/response.rb
module Response
extend ActiveSupport::Concern
def json_response(object, status = :ok, opts = {})
response = {json: object, status: status}.merge(opts)
render response
end
def respond_with_errors(object)
render json: { errors: ErrorSerializer.serialize(object) }, status: :
unprocessable_entity
end
def paginated_response_status(collection)
collection.size > WillPaginate.per_page ? :partial_content : :ok
end
end
The ApplicationController includes the above concern as follows:
#controllers/application_controller.rb
class ApplicationController < ActionController::API
include Response
...
end
Thank you!
