Rails Functional Testing Problem

I'm trying to run some functional tests on Rails. However I am coming up
with the following error.

RuntimeError: Called id for nil, which would mistakenly be 4 -- if you
really wanted the id of nil, use object_id
    app/controllers/posts_controller.rb:11:in `create'
    posts_controller_test.rb:5:in `test_should_create'

Here is my test file

require File.dirname(__FILE__) + "/../test_helper"

class PostsControllerTest < ActionController::TestCase
def test_should_create
  post :create, :post => { :message => 'Sausage and Egg Sandwich'}
end
end

Here is my controller

class PostsController < ApplicationController
  def index
    @posts = Post.all(:order => "created_at DESC")
    respond_to do |format|
      format.html
    end
  end

  def create
    @post = Post.create(:message => params[:post])
    @post.user_id = current_user.id
    respond_to do |format|
      if @post.save
        format.html { redirect_to posts_path }
        format.js
      else
        flash[:notice] = "Message failed to save."
        format.html { redirect_to posts_path }
      end
    end
  end
end

Assuming that it is this line that is causing the error, what is the
value of current_user when you run the test?

Nil. Because I haven't specified it, and the user isn't logged in. I've
tried invoking the current_user or writing user_id within the test, but
that hasn't worked.

You need to be logged in order to write a post, but I wasn't sure that
mattered when writing the test?

Of course it matters, the tests should, for example, check that you
cannot do things that you should not be able to do without logging in.
How to accomplish this depends on how your authentication is done.
Perhaps you need to set something in the session before running the
test. Google should show you how to do that.

Thank you Colin

I'm using nifty-authentication for what it's worth

Really struggling attempting to implement this globally.

Any suggestions to those who have used nifty_authentication?

Once again you have not quoted previous messages so anyone finding
this would have difficulty following the thread. I don't know about
nifty_authentication but for authlogic the logon action actually
creates a UserSession, so to logon in the test one does something like
    UserSession.create( users(:test_user) )
