Module Authorization::TestHelper
In: lib/declarative_authorization/maintenance.rb

TestHelper provides assert methods and controller request methods which take authorization into account and set the current user to a specific one.

Defines get_with, post_with, get_by_xhr_with etc. for methods get, post, put, delete each with the signature 

  get_with(user, action, params = {}, session = {}, flash = {})

Use it by including it in your TestHelper: 

 require File.expand_path(File.dirname(__FILE__) +
   "/../vendor/plugins/declarative_authorization/lib/maintenance")
 class Test::Unit::TestCase
   include Authorization::TestHelper
   ...

   def admin
     # create admin user
   end
 end

 class SomeControllerTest < ActionController::TestCase
   def test_should_get_index
     ...
     get_with admin, :index, :param_1 => "param value"
     ...
   end
 end

Note: get_with etc. do two things to set the user for the request: Authorization.current_user is set and session[:user], session[:user_id] are set appropriately. If you determine the current user in a different way, these methods might not work for you.

Public Class methods

Public Instance methods

assert_raise_with_user(user, *args, &block)

Analogue to the Ruby‘s assert_raise method, only executing the block in the context of the given user.

should_be_allowed_to(privilege, *args)

Test helper to test authorization rules. 

  with_user a_normal_user do
    should_not_be_allowed_to :update, :conferences
    should_not_be_allowed_to :read, an_unpublished_conference
    should_be_allowed_to :read, a_published_conference
  end

If the objects class name does not match the controller name, you can set the object and context manually 

  should_be_allowed_to :create, :object => car, :context => :vehicles

If you use specify the object and context manually, you can also specify the user manually, skipping the with_user block: 

  should_be_allowed_to :create, :object => car, :context => :vehicles, :user => a_normal_user
