validates_uniqueness_of(*attr_names) w scope not working in unit test

Rails 3.2.8

Very strange , it works in dv mode console , but not in a unit test

class User < ActiveRecord::Base

  belongs_to :subdomain

  validates_uniqueness_of :email, :scope => :subdomain_id

class UserTest < ActiveSupport::TestCase

  def initialize_user

    @booboo = FactoryGirl.create(:subdomain, name: "booboo")

    @coocoo = FactoryGirl.create(:subdomain, name: "coocoo")

    FactoryGirl.create(:user, subdomain_id: @booboo[:id], email: "user...@acme.com", password: "UkZaHWcy", password_confirmation: "UkZaHWcy")

  end

  def teardown

    User.delete_all

    Subdomain.delete_all

  end

 test "should_save_user_with_duplicated_email_in_another_scoped_subdomain" do

    user = FactoryGirl.build(:user, subdomain_id: @coocoo[:id], email: "user...@acme.com", password: "UkZaHWcy", password_confirmation: "UkZaHWcy")

    assert user.save # failing  @messages={:email=>["has already been taken"]}

  end

Now in console

>    @booboo = FactoryGirl.create(:subdomain, name: "booboo")

>    @coocoo = FactoryGirl.create(:subdomain, name: "coocoo")

>     FactoryGirl.create(:user, subdomain_id: @booboo[:id], email: "user...@acme.com", password: "UkZaHWcy", password_confirmation: "UkZaHWcy")

>      user = FactoryGirl.build(:user, subdomain_id: @coocoo[:id], email: "user...@acme.com", password: "UkZaHWcy", password_confirmation: "UkZaHWcy")

>  user.save

  COMMIT

 => true 

why do the same Model have different behaviors in test mode and dev mode ?   any clue ?

thanks for feedback

[SOLVED]

weird environment => weird behaviour

I had a duplicated copy of my User model file still in my models folder ...  filename was user_copy.. but containing a User class def..

I guess running in the console, the first user model file was used , but in unit test , the copy was used ...

need a break .. tea time ! not tea party !
