The Coding Dojo page for this kata also has a video of it performed in Ruby. There’s also a link to a video of it in Excel, but as much as it sounds good, it’s just building a VB macro…
The previous kata sessions used Jasmine – and it works just fine – but I chose to do things with YUI Test. If you feel like it – I prepared a skeleton for the project. Note that it loads YUI from Yahoo’s CDN, so make sure you’re online (or update the harness.html).
