in chapter 13

def test\_100\_orders  
Order.delete\_all  
LineItem.delete\_all

```
@controller.logger.silence do

  elapsed_time = Benchmark.realtime do
    100.downto(1) do |prd_id|
      cart = Cart.new
      cart.add_product(Product.find(prd_id))
      post :save_order,
           { :order => DAVES_DETAILS },
           { :cart => cart }
      assert_redirected_to :action => :index
    end
  end
  assert_equal 100, Order.count
  assert elapsed_time < 3.00

end

```

end

my question is : the test is ok, but after this test, my mysql  
depot\_test’s  
orders table is empty and produtions table has 1000 records.

but in the test:assert\_equal 100, Order.count is ok?

why?

just because self.use\_transactional\_fixtures = true

🙂 I resolved this problem by myself.
