RSpec 2 equivalent for Rails::Generators::TestCase?

Testing RSpec
1

I have been creating a lot of Thor generators and Rails generators
during the past 4 months, but only this week did I find some good
examples of how to write tests for generators using
Rails::Generators::TestCase - in the “rails3-generators” project.

I prefer to write my tests in RSpec 2, so I was wondering if there is
an RSpec 2 equivalent out there yet?
If not, I will try writing my own RSpec 2 port… but I would be very
happy if anyone could help me in this effort, with suggestions or
anything.
Thanks!

Test::Unit example

require ‘generator_helper’

class Canable::Generators::ModelGeneratorTest <
Rails::Generators::TestCase
destination File.join(Rails.root)
tests Canable::Generators::ModelGenerator

setup :prepare_destination
setup :copy_routes

def assert_model(name, options)
assert_file “app/models/#{name}.rb” do |account|
assert_class name.camelize, account do |klass|
assert_match /include Canable::Ables/, klass

    assert_match(/userstamps!/, klass) if options[:userstamps]

    if method = options[:method]
      assert_match(/def #{method}_by?(user)/, klass) if method
    end
  end
end

end

test “invoke with no arguments” do
run_generator
end

test include Canable:Ables statement is added

test “invoke with model name” do
name = ‘house’
run_generator(name)
assert_model(name)
end
end
