describe User, ".admins" do
  it "includes users with admin flag" do
    admin = User.create! :admin => true
    User.admin.should include(admin)
  end

  it "excludes users without admin flag" do
    non_admin = User.create! :admin => false
    User.admin.should_not include(non_admin)
  end
end

class User < ActiveRecord::Base
  named_scope :admins, :conditions => {:admin => true}
end
