Beginner needs help

Rails

Hi, I am trying to follow the book ‘Beginning Ruby on Rails e-commerce’
examples.

When I come to unit testing I get an error message:
C:/Ruby/bin/ruby.exe -I"lib;test"
“C:/Ruby/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake/rake_test_loader.rb”
“test/unit/author_test.rb” “test/unit/helpers/about_helper_test.rb”
C:/Ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.2/lib/active_support/dependencies.rb:440:in
`load_missing_constant’: uninitialized constant Test::Unit::Testcase
(NameError)

My test/unit/author_test.rb looks like this:

require File.dirname(FILE) + ’ /…/test_helper’

class AuthorTest < Test::Unit::Testcase
fixtures :authors
def test_name
author=Author.create(:first_name => ‘Joel’,
:last_name => ‘Spolsky’)

assert_equal 'Joel Spolsky', author.name

end
end

Why do I get the error message ?

What version of Rails are you using?

class AuthorTest < Test::Unit::Testcase

change the above to

class AuthorTest < ActiveSupport::TestCase

He’s using 2.3.2 from the errors…

So, did you create everything from scratch? Or, did you read a section
in the book that said go to x website and download the incomplete or
complete samples and you are working from those?

If you are working from samples, the samples are probably not using the
same RoR version you are. That’s the very first question I’d answer.

Most books and source files that go with those books are out of date
already.

class AuthorTest < Test::Unit::Testcase

Thanks guys,
I have been out of town a few days, thats why this late reply.

I am using Rails 2.3.2 The book was published in 2006 so I guess the
examples can be out of date. I ran into that when the book mentioned
start-form-tag and end-form-tag… Took me a while to figure that out.

Anyways, I am buildng all the examples from scratch, and so far I have
not downloaded anything, so it could be a typo, even though I have
checked the code several times…

Tha last two suggestions I haven’t tried yet, but I will.

cheers,
