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 While I do have backups, the original source code is in a very outdated state so I currently don't feel it makes sense to try and get it running again.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.

konacha

Konacha is a Rails engine that allows you to test your JavaScript with the mocha test framework and chai assertion library. It is similar to Jasmine and Evergreen, but does not attempt to be framework agnostic. By sticking with Rails, Konacha can take full advantage of features such as the asset pipeline and engines.
