The great guys over at New Bamboo (a British Ruby on Rails development team) have launched a new blog and their first post is a tour through the testing methods available in Rails. It's ideal for those who've fallen behind with their Rails testing knowledge or those who want to get up to speed quickly.

They cover unit tests, testing relationships, testing validations, show how to put CRUD tests together, and how to test HTML coming out of your app. All useful stuff, and as they say.. you never know when the brakes might fail.
