How to test if @fleet_group exists in rspec2 + rails3 + devise

application_controller.rb

class ApplicationController < ActionController::Base
  protect_from_forgery
  
  before_filter :authenticate_user!, :store_location

  def stored_location_for(resource)
    nil
  end

  def after_sign_in_path_for(resource)
    set_time_zone
    set_schema_name
    session[:fleet_group_id] = current_user.default_fleet_group.id
    session[:fleet_id] = current_user.default_fleet.id

    stored_location_for(resource) || to_do_path
  end

  rescue_from CanCan::AccessDenied do |exception|
    flash[:error] = exception.message
    redirect_to access_denied_url
  end

  def store_location
    session[:return_to] = request.referer if request.get? and controller_name != "sessions"
  end

  def set_time_zone
    session[:time_zone] = current_user.time_zone
    Time.zone = session[:time_zone]
  end

  def set_schema_name
    session[:schema_name] = current_user.default_fleet_group.schema_name
  end

end

status_controller.rb

class StatusController < ApplicationController
  include PgTools

  def fleet
    unless params[:schema_name].blank?
      PgTools.set_search_path(params[:schema_name])
    else
      PgTools.set_search_path(session[:schema_name])
    end

    unless params[:fleet_ids].blank?
      fleet_id = params[:fleet_ids].split(",")
    else
      fleet_id = session[:fleet_id]
    end

    @fleet_groups = current_user.fleet_groups
    @fleets = current_user.fleets

    fleet = current_user.fleets.where(:id => fleet_id).first
    @units = fleet.units.not_hidden.with_active_session

  end
end

status_controller_spec.rb

require 'spec_helper'

describe StatusController do
  include Devise::TestHelpers

  before (:each) do
    @current_user = User.find_by_username('rupert')
    sign_in @current_user
  end

  it "should have fleet groups and fleets for sidebar" do
    assigns(:fleet_groups).should_not be_nil
  end

  #describe "GET 'fleet'" do
  #  it "should be successful" do
  #    get 'fleet', :schema_name => 'dfms_4000', :fleet_ids => [4000]
  #    response.should be_success
  #  end
  #end

end
