Rails - Jun 2006 - @version_control_book not available while testing - AWD book 1 page 148

In the page 148 of the AWD book it''s mentioned that the while testing

@products and @version_control_book are automatically made available.

That''s not the case with me.  In my test environment I don''t
get those two
variables.

I was wondering if anything has changed in Rails 1.1 because in the new
edition of the book (AWD - edition 2) there is no mention of such feature in
testing chapter?

Thanks

On-Demand Instantiated Fixtures

By default in Rails 1.0, fixtures aren''t instantiated and assigned to 
instance variables until you need them. Whereas previous releases would 
automatically create a @version_control_book instance variable, for 
example, before each test method, you can now use the fixture accessor 
method products(:version_control_book) to load fixture data into 
variables on demand.

So before running the test with instantiated fixtures disabled, we need 
to change the tests to use fixture accessor methods:

    def test_add_one_product
      @cart.add_product products(:version_control_book)
      assert_equal 1, @cart.items.size
    end

    def test_add_duplicate_products
      @cart.add_product products(:version_control_book)
      @cart.add_product products(:version_control_book)
      @cart.add_product products(:automation_book)
      assert_equal 2, @cart.items.size
    end
