ruby script/plugin install git://github.com/nbibler/should_require_login.git

What's it do?
===============

This plugin adds a method to your functional tests which is creatively named should_require_login. This assertion will verify that the given list of views (with optional request parameters) requires that a user be authenticated prior to successful access.

How's it do that?
===============

To verify that authentication is required, the assertion will check that accessing each given view, when no user is signed in, will result in a redirection to your sign in page (oh, by the way, you are required to have a named route called login_url).

The encapsulation of the assertion logic is written for Shoulda[http://www.thoughtbot.com/projects/shoulda], and so using Shoulda is required. (opinionated, remember?)

While I'm mentioning these nuances, I should also mention that you're required to also have the following methods available:
login_as(user/nil):To set the user with whom the test should login. This method should also accept nil to log in as nobody.

Example
===========
Since this plugin will really only work with Shoulda (you read that already, right?), here you go:

    class FoosControllerTest < ActionController::TestCase

      context 'FooController' do

        should_require_login :new, :edit
        should_require_login :create,     :method => :post,   :params => {:name => 'bar'}
        should_require_login :update,     :method => :put,    :params => { :id => 1 },    :with_user => lambda { users(:foo) }
        should_require_login :destroy,    :method => :delete

      end

    end

There is currently no advanced documentation for this plugin.
