Reloader guard automatically reload file definition and launch proper tests when files are modified or created.

Please be sure to have Guard and Test::Unit installed before continue.

If you're using Bundler, add it to your Gemfile (inside the development group):

gem 'guard-reloader'

and run:

$ bundle install

or manually install the gem:

$ gem install guard-reloader

Add Guard definition to your Guardfile by running this command:

$ guard init reloader

$ cd [path-to-your-rails-project]
$ guard

Guard::Reloader at the moment support only modification in model and controller.

guard 'reloader' do
  watch(%r{^app/models/(.+)\.rb$})
  watch(%r{^test/unit/(.+)\.rb$})
  watch(%r{^app/controllers/(.+)\.rb$})
  watch(%r{^test/functional/(.+)\.rb$})
end

Please read the Guard documentation for more info about the Guardfile DSL.
