To use rspec for testing you must install rspec gem:

  exit(0)

desc "Run the specs under spec/models"
Spec::Rake::SpecTask.new do |t|
  t.spec_opts = ['--options', "spec/spec.opts"]
  t.spec_files = FileList['spec/*_spec.rb']
end
```

Fix the rake 'spec' task to see all of the specs, including those in subdirectories.
