Why does this RSpec test not work?

I learn Ruby on Rails, so I treat me like a complete neophyte, because I am.

I have a User model with some related RSpec tests, and the following test fails:

require 'spec_helper'
describe User do

    it 'should require a password' do
        User.new({:email => 'valid_email@example.com', :password => '', :password_confirmation => ''}).should_not be_valid
    end

end

The relevant part of the model is Useras follows:

class User < ActiveRecord::Base
    ...
    validates :password, :presence => true,
                         :confirmation => true,
                         :length => { :minimum => 6 }
    ...
end

Here's the catch: if I started User.new(...).valid?from the Rails console using the above arguments, it returns false as expected and shows the correct errors (password is empty).

I used spork / autotest and I restarted both to no avail, but this test also does not allow to run it directly with rspec. What am I doing wrong here?

EDIT

I tried a few more things with the test. This fails:

        u = User.new({:email => 'valid_email@example.com', :password => '', :password_confirmation => ''})
        u.should_not be_valid

So does it:

        u = User.new({:email => 'valid_email@example.com', :password => '', :password_confirmation => ''})
        u.valid?
        u.errors.should_not be_empty

, , :password :

        u = User.new({:email => 'valid_email@example.com', :password => '', :password_confirmation => ''})
        u.password.should == ''
