How to test refinery sessions controller

Question

I've overridden Refinery's session controller and not even modified it yet, as I'm trying to write some specs for it.

The controller lives in app/controllers/refinery/sessions_controller:

module Refinery
  class SessionsController < Devise::SessionsController
  ....
  def create                 
      super
      rescue ::BCrypt::Errors::InvalidSalt, ::BCrypt::Errors::InvalidHash
      flash[:error] = t('password_encryption', :scope => 'refinery.users.forgot')
      redirect_to refinery.new_refinery_user_password_path
  end
  ..... 

I then am trying to write a spec against this in spec/controllers/refinery/sessions_controller_spec.rb:

require 'spec_helper'
  describe Refinery::SessionsController do
    it "should post ok" do
      post :create
      response.should be_success 
    end     
  end 

However this is giving me an error

No route matches {:action=>"create", :controller=>"refinery/sessions"}

This confuses me as when I run rake routes, I get the following line:

 refinery_user_session POST    /refinery/users/login(.:format)              refinery/sessions#create

Could anyone help?

Rails 3.2.8, refinery 2.0.8
