Guard is a command line tool to easily handle events on file system modifications.

Guard::RSpec automatically run your specs (much like autotest).

Modern continious testing (flexible alternative to autotest).

Guard::RuboCop automatically checks Ruby code style with RuboCop when files are modified.

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.

Insert LiveReload into your app easily as Rack middleware

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.

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.

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

Runs your tests as they change, in parallel.

This is a stub gem to fix the confusion caused by autotest being part of the ZenTest suite. In now points to minitest-autotest as that has been extracted and massively enhanced beyond the original ZenTest autotest.

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.

Allows you to fire specific command on file-system change.

Simple Minitest reporter to indicate the result of test runs. After every test run, the reporter invokes the `minitest-flash` executable (created by you and to your liking) with either the argument "green" or "red" to reflect the result of the run.
