I had already created all relevant text fixtures and had already 
modiefied my product_test.rb file prior to running this for my test 
database.

im not sure if this will solve your problem but i almost had the same 
error. im also learning and following the book.

make sure you dont use or insert tabs in products.yml . all the while i 
thought i use spaces instead of tabs. for example:

programmer_book:
  id:                1
  title:             Pragmatic Programmer
  description:       Best book for the programmer
  image_url:         http://localhost:3000/images/pp.jpg
  price:             29.95
  date_available:    2006-05-01 00:00:00
^^               ^^^^

in this example, all the spaces (indicated with ^) should be a space and 
not tab. i kept on getting errors and i was thinking maybe because i was 
using rails 1.1.2 so i reverted back to 1.0. still there were errors. 
the culprit was, i didnt know i was using tabs on the start of the line 
(before the key). and i thought space should be used only in between the 
key and value. after that, my test was successful and solved the ENOENT 
error.
