How to mock an instance method of an already mocked object ?

Question

I need to mock the following:

Class User
  def facebook
    #returns an instance of a facebook gem
  end
end

So in my User tests, to access the User's facebook info I need to call user.facebook.me.info to retrieve its info. If I want to mock this, I'm currently using the following:

@user = Factory(:user)
facebook = mock()
me = mock()
me.expects(:info).returns({"name" => "John Doe"})
facebook.expects(:me).returns(me)
@user.expects(:facebook).returns(facebook)
assert_equal "John Doe", @user.facebook.me.info["name"]

This works but seems a bit unwieldy, is there a better way to do this ?

[edit] I'm using mocha as mocking framework
