Bad news. The server hosting The Ruby Toolbox went bust on the evening of June 7th. While I do have backups, the original source code is in a very outdated state so I currently don't feel it makes sense to try and get it running again.

For the time being, here is a very stripped down version of the Ruby Toolbox's contents.

Update June 13th: I'd like to invite you to join the discussion on the future of the Toolbox on github. You can also get in touch directly on Twitter.

ZenTest

ZenTest provides 4 different tools: zentest, unit_diff, autotest, and multiruby. zentest scans your target and unit-test code and writes your missing code based on simple naming rules, enabling XP at a much quicker pace. zentest only works with Ruby and Minitest or Test::Unit. There is enough evidence to show that this is still proving useful to users, so it stays. unit_diff is a command-line filter to diff expected results from actual results and allow you to quickly see exactly what is wrong. Do note that minitest 2.2+ provides an enhanced assert_equal obviating the need for unit_diff autotest is a continous testing facility meant to be used during development. As soon as you save a file, autotest will run the corresponding dependent tests. multiruby runs anything you want on multiple versions of ruby. Great for compatibility checking! Use multiruby_setup to manage your installed versions. *NOTE:* The next major release of zentest will not include autotest (use minitest-autotest instead) and multiruby will use rbenv / ruby-build for version management.

This gem aims to improve support for Growl notifications by autotest.

autotest-fsevent

Autotest relies on filesystem polling to detect modifications in source code files. This is expensive for the CPU, harddrive and battery - and unnecesary on Mac OS X 10.5 or higher which comes with the very efficient FSEvent core service for this very purpose. This gem teaches autotest how to use FSEvent.

tconsole

tconsole allows Rails developers to easily and quickly run their tests as a whole or in subsets. It forks the testing processes from a preloaded test environment to ensure that developers don't have to reload their entire Rails environment between test runs.

Infinity Test

Infinity Test is a continuous testing library and a flexible alternative to Autotest, using Watchr library with RSpec, Test::Unit or Bacon with RVM funcionality, giving the possibility to test with all Rubies that you have in your RVM configuration.
