RSpec attribute specifier

Question

I use Sinatra (1.2) and RSpec (2.5) and would like to create a new object with the TDD style attribute. Here's what the end result should look like:

class User
  def initialize(name)
    @name = name
  end
end

I know that I should write an example before implementation, but I'm trying to explain my question here. :) This is not the working specification that I still have:

describe User
  it "creates a new user object" do
    name = mock("A name")
    user = mock(User) # shouldn't do this, see the reply's
    user.should_receive(:name=).with(name)
    User.new(name)
  end
end

When I start RSpec, I get the error message "Expected: 1 time, received 0 times". Any idea how I can explain RSpec, I would like to assign an attribute to a name?

Note. I do not use Rails, not using ActiveRecord or anything else, just Ruby.

require 'rspec'

class User
  attr_accessor :name

  def initialize(name)
    @name = name
  end 
end

describe User do
  subject {User.new "other name"}

  it "creates a new user object" do
    subject.should respond_to :name=
  end 
end
