Setting up Testing model, getting an error

Rails

I setup a testing model in my Depot web app from the Agile Web
Development with Rails book and came up with the following errors:

Loaded suite test/unit/product_test

  1. Error:

1 tests, 0 assertions, 0 failures, 2 errors

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.
