rspec users - Sep 2007 - Authenticating before tests

Hi all,

I''m using Goldberg, an engine that provides roles based access  
control for my app. I need to login before I can do controller tests,  
but I can''t find any examples of people doing this.

Could someone point me in the right direction?

I thought the simplest way would be to either call the login action  
from my other tests before(:all), but I can''t seem to find how to  
call another controller from within the spec for a different  
controller. (Results in @controller is nil).

I''ve also tried setting session[:user] in before(:all), but session  
is nil at that point!

Any help would be greatly appreciated.

Thanks,
Luke

This is what we do:

in spec_helper.rb:

   include AuthenticatedTestHelper

   def login_as(user)
     controller.send :current_user=, user
   end

Then, in a before(:all) block, I can say login_as(@user) with a user  
object. This assumes you''re using restful_authentication (and should  
work with acts_as_authenticated as well).

You can''t and shouldn''t do that. Just find out how your
particular
authentication system determines the login and create a helper method  
like login_as above to simulate the login.

Hi!
Have you considered mocking / stubbing to test in isolation if that is
appropriate ?

Right, my example was also assuming that you are using mocks for users.

This is what we do.  I realize that according to the another poster this is
the wrong way, but it is the best way we''ve found for use with
Goldberg.

  def goldbergAuthAdmin()
    get ''goldberg/auth/login''
    #Goldberg::AuthController.set_user(session,
Goldberg::User.find_by_name(:first, "admin").id)
    #Our Admin user has id 2.
    Goldberg::AuthController.set_user(session,2)
  end

BTW, another important step is bootstrapping goldberg into your test
database...

To facilitate this we added two methods to the GoldbergMigration model:
  def self.clear_for_class(klass, dest)
    filename = "#{dest}/#{klass.to_s.sub(/^Goldberg::/,
'''')}.yml"
    records = klass.delete_all
  end
  def self.clear_bootstrap
    self.goldberg_classes.each do |klass|
      self.clear_for_class klass, "#{File.dirname(__FILE__)}/../db"
    end
  end

Then add this to spec_helper.rb, or your own included spec_helper
  def goldbergReload()
    GoldbergMigration.clear_bootstrap
    GoldbergMigration.load_bootstrap
  end

Then call this from a before(:all) in the first describe of each rspec
needing goldberg.  Of course you have to have dumped your goldberg bootstrap
from dev/production first (You do this in the console:
"GoldbergMigration.dump_bootstrap" to save all goldberg settings,
controller/action perms, users roles, etc to some yaml files).

Hope that helps!

Hi Peter,

I ended up settling on having a "ensure_goldberg_loaded" helper in  
spec_helper and a login_as that "spoofs" the session in the way that  
set_user would do but without relying on Goldberg. This should make  
it less coupled with Goldberg and let you test your code without  
testing goldberg at the same time.

It really just involves creating a goldberg session object with the  
user_id and a blank menu_history.

Here''s the revelant bits of my spec_helper:

def ensure_goldberg_loaded
   if Goldberg::User.find(:all).empty?
     GoldbergMigration.load_bootstrap
   end
end

def login_as( user = ''admin'' )
   request.session[:goldberg] = { :user_id => Goldberg::User.find 
(:first, :conditions => "name=\"#{user}\"").id,
       :menu_history => {} }
end


Then I use it in my specs:

before(:all) do
     ensure_goldberg_loaded
  end

before(:each) do
     login_as :galeal
  end

Thanks for your help!
