test-loop - Continuous testing for Ruby with fork/eval
http://github.com/sunaku/test-loop
···
======================================================
test-loop is a fast continuous testing tool for Ruby that continuously
detects and tests changes in your Ruby application in an efficient
manner, whereby it:
1. Absorbs the test execution overhead into the main Ruby process.
2. Forks to evaluate your test files directly and without overhead.
It relies on file modification times to determine what parts of your
Ruby application have changed and then uses Rake's `String#pathmap`
function to determine which test files in your test suite correspond
to those changes.
Features
--------
* Tests CHANGES in your Ruby application; does NOT run all tests
every time.
* Reabsorbs test execution overhead if the test or spec helper file
changes.
* Mostly I/O bound, so you can have it always running without CPU
slowdowns.
* Supports Test::Unit, RSpec, or any other testing framework that is
utilized by your application's `test/test_helper.rb` and
`spec/spec_helper.rb` files.
* Implemented in less than 50 (SLOC) lines of code! 
Installation
------------
As a Ruby gem:
gem install test-loop
As a Git clone:
git clone git://github.com/sunaku/test-loop
Invocation
----------
If installed as a Ruby gem:
test-loop
If installed as a Git clone:
ruby -Ilib bin/test-loop
Operation
---------
* Press Control-Z (or send the SIGTSTP signal) to forcibly run all
tests, even if there are no changes in your Ruby application.
* Press Control-\ (or send the SIGQUIT signal) to forcibly reabsorb
the test execution overhead, even if its sources have not changed.
* Press Control-C (or send the SIGINT signal) to quit the test loop.
