Question

I am currently trying to make a dropbox-esque application from a tutorial and I am having trouble trying to figure out how I would test this controller.

this is the AssetsController page

    def index
       @assets = current_user.assets
    end

    def show
       @assets = current_user.assets.find(params[:id])

Also, assets belong_to :user and user has_many :assets

How would I go about putting that into an rspec test?

Answer 1

Firstly, be very careful about AssetsController.

Assuming you are using Rails 3, the “assets_path” is also the path used to load your application assets, and hence, anything you write to the session in that controller will be ignored silently. Probably not what you want! I’d strongly consider renaming the controller.

I’d first create the user in a sign-in block

module ControllerMacros
  def login_user
    before(:each) do
      @request.env["devise.mapping"] = Devise.mappings[:user]
      @user = Factory.create(:user)
      sign_in @user
    end
  end
end

You can then load this in the spec_helper.rb file

RSpec.configure do |config|
  config.include Devise::TestHelpers, :type => :controller
  config.extend ControllerMacros, :type => :controller
end

Finally, you can use this in the test

describe MyController do
  context "#index" do
    login_user
    before(:each) do
      @assets = []
      5.times{ @assets << Factory.create(:asset, :user => @user)}
    end

    it "should test index" do
      get :index
      assigns(:assets).should eq(@assets)
    end
  end
end

Now, that should test your asset list correctly.

EDIT: Just realised, I’m using FactoryGirl/Devise here, you may or may not be!
