rspec users - Aug 2010 - RSpec 2 add-on for testing and specifying generators - initial release

http://github.com/kristianmandrup/rspec_for_generators

When creating Rails generators I noticed that the only option I could
find for testing was to use a special Rails TestCase class created
specifically for use with Test Unit.
So I thought I could wrap it to be used with RSpec 2 instead. I now
have a working first release with room for lots of improvements!  But
at least it seems to work fine for now, as demonstrated by a small
RSpec 2 test suite that comes with it.

Note: This library is NOT in any way an official RSpec 2 release of
any sort. I only use the RSpec name to indicate that it is an add-on
component for RSpec 2. That it can be used with RSpec 2.
Not sure what other convention there would be to indicate this?

Maybe I should rename it to something like the following to make it
more clear?

rspec2-addon-for-generators

Hope you find it useful as a starting point. Free feel to patch it,
refactor etc.
Enjoy!

Ben Mabey called his email-spec. So maybe generator-spec?

Alright, I will rename it when I get to it. Just improved it in a
major fashion! Now as simple as this to set it up :)

# spec/spec_helper.rb

require ''rspec''
require ''rspec_for_generators''

Rails.application.configure do
  # use default rails tmp dir
  config.root_dir = TmpRails.root_dir(__FILE__)
end

# configure it!
RSpec::Generator.configure!

And to use it in a spec:

require File.expand_path(File.dirname(__FILE__) +
''/../spec_helper'')
require_generator :demo

describe ''model_generator'' do
  include RSpec::Rails::Orm::ActiveRecord

  before :each do
    RSpec::Generator.setup_generator ''model_generator'' do
      tests DemoGenerator
    end
    remove_model ''account''
  end

  after :each do
    remove_model ''account''
  end

  it "should decorate an existing Account model file with include
Demo" do
    RSpec::Generator.with_generator do |g|
      name = ''account''
      create_model name
      g.run_generator %w{account}
      g.should generate_file name, :model do |content|
        content.should have_class name do |klass|
          klass.should include_module ''Demo''
        end
      end
    end
  end
end

Even simpler config now :)

require ''rspec''
require ''rspec_for_generators''

# configure it like this to use default settings
RSpec::Generator.configure_root_dir(__FILE__)
