Integration Testing w/ Sorcery

integration_spec.rb

describe "Shopping Cart Requests" do
  let!(:user) { Fabricate(:user) }

  before(:each) do
    login_user_post("admin", "admin")
  end

  context "when I visit the shopping cart" do
    it " show the logged in users' cart items " do
      #Test stuff
    end
  end
end

spec_helper.rb

RSpec.configure do |config|  
  config.include Sorcery::TestHelpers::Rails
end

module Sorcery
  module TestHelpers
    module Rails
      def login_user_post(user, password)
        page.driver.post(user_sessions_url, { username: user, password: password}) 
      end
    end
  end
end

user_fabricator.rb

Fabricator(:user, :class_name => "User") do
  id { sequence }
  username { "admin" }
  password { "admin" }
  display_name { "Admin Boom"}
  admin { true }
  email { "whatever@whatever.com" }
  salt { "asdasdastr4325234324sdfds" }
  crypted_password { Sorcery::CryptoProviders::BCrypt.encrypt("secret", 
                     "asdasdastr4325234324sdfds") }
end

I'm getting extremely frustrated with Capybara, Rspec, Factory_girl/Fabricator and Sorcery. I've been trying for 3 hours or so now to just log in a stupid user and nothing works. I found this gist and thought that my problems were solved, but no...they're not. I keep getting:
ActionController::RoutingError:
No route matches [POST] "/login"

Or:
NameError:
undefined local variable or method `login_path'

Depending on which I user for this:
def login_user_post(email, password)
page.driver.post(login_path, { email: email, password: password})
end

Same for new_session_path and anything else I put there. I just don't get it. Why is it so unbelievably difficult to get a user logged in with Sorcery? I built a little test site a couple weeks ago with Devise instead and it worked brilliant with no obnoxious hackery or any of this other stuff and if it wasn't going to be incredibly painful to switch over all user accounts to Devise, I would just do that.

@kkerley I'm having this exact same problem and I've wasted tons of time on this, does anyone know any hacks or ways around this?

This gist doesn't work for me either, I also either get ActionController::RoutingError:
No route matches [POST] "/login"

Or:
NameError:
undefined local variable or method `login_path'

Or:
NameError:
undefined local variable or method `page' for #<RSpec::ExampleGroups:

Did you guys ever figure this out?
I'm getting the undefined local variable or methodpage' for ...` issue

@anlek : same error here.
