Rails-Usage page example leads to conceptually wrong behavior

Hi.

I am trying to test a Rails app with rubydoctest. To run the tests and integrate it with my CI bot, I set this rake task:

desc "Run all doctests"
task :doctest do
  require './config/environment'
  require 'database_cleaner'
  begin
    desc "Run doctests"
    sh "rubydoctest #{File.dirname(__FILE__)}/doc/doctests/*.doctest" do |ok, res|
      raise "Failed doctest." if !ok
    end
  rescue LoadError
    puts 'Oops: Cannot load doctests!'
  end
end

and this test helper, derived from https://github.com/tablatom/rubydoctest/wiki/Rails-Usage

ENV['RAILS_ENV'] = 'test'

require './config/environment'
require 'database_cleaner'

DatabaseCleaner.strategy = :truncation, {:except => %w[schema_migrations]}

module RubyDocTest
  class Test
    alias :old_pass? :pass?

    def pass?
      DatabaseCleaner.start
      result = old_pass?
      DatabaseCleaner.clean
      result
    end
  end
end

but something is going wrong when trying to create an User and reloading it from the database. The following fails, but only on the second part:

doctest: Create a new user and save to the database
>> u0 = User.create! :email => 'alberto@example.com', :password => 'password',
>> u0.id
=> 1

doctest: Be sure that the user is still at the database
>> User.all.length == 1

Its because each "doctest:" sign starts a new test. However, the database is reset to initial state but not the context. I believe that the database should be reset only after all the tests of this "file". Can someone please point me some piece of code to look for creating a patch, if possible?

I found that the recipe is the problem. The class monkeypatched should be Runner instead of Test as in:

module RubyDocTest
  class Runner
    alias :old_pass? :pass?

    def pass?
      DatabaseCleaner.start
      result = old_pass?
      DatabaseCleaner.clean
      result
    end
  end
end

It works for me. I updated the documentation wiki

I has wrong. This "Runner monkeypatch" have no efect. Domentation reverted and bug reopened. Forking and trying to fix it.
