RAILS_ROOT issue - plugin unit tests won't work under vendor/plugins

Hi,

I’m relatively new to Ruby/Rails (and developing on Windows boxes).
I’ve inherited a system and am trying to get the unit tests for a
plugin running in Windows. Specifically, I have a plugin with some
unit tests running under my app’s vendor/plugins dir. When I try and
run a specific model unit test I get a failure:


c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`gem_original_require’: no such file to load – C:/Documents and
Settings/leedoejgi/workspace/Ruby/config/environment (LoadError)

It’s looking in C:/Documents and Settings/leedoejgi/workspace/Ruby/
config/environment instead of C:/Documents and Settings/leedoejgi/
workspace/Ruby/myapp/clients/myapp_client/config/environment.

The unit test is requiring test_helper in the same directory, which
looks like this:


$:.reject! { |e| e.include? ‘TextMate’}
ENV[“RAILS_ENV”] = “test”

unless defined? RAILS_ROOT
RAILS_ROOT = ‘…/…/…’
end

require File.expand_path("#{RAILS_ROOT}/config/environment")
require ‘test_help’
require ‘logger’
require ‘fileutils’

If I set an environment variable for RAILS_ROOT in Windows of and make
the following changes to test_helper give it the right RAILS_ROOT


$:.reject! { |e| e.include? ‘TextMate’}
ENV[“RAILS_ENV”] = “test”

Support for NetBeans testing in Windows with RAILS_ROOT set in

environement.
if !ENV[‘RAILS_ROOT’].empty?
RAILS_ROOT = ENV[‘RAILS_ROOT’]
end

unless defined? RAILS_ROOT
RAILS_ROOT = ‘…/…/…’
end

require File.expand_path("#{RAILS_ROOT}/config/environment")
require ‘test_help’
require ‘logger’
require ‘fileutils’

I now get a different error:


c:/ruby/lib/ruby/gems/1.8/gems/rails-2.0.2/lib/initializer.rb:499:in
`replace’: can’t modify frozen string (TypeError)

Can anyone offer me guidance on how to get the unit tests running
under Windows?

Thanks!
