This article is hilarious. If you want to see why TDD, unit testing, isolation, etc. are important, a Rails app written the "Rails Way" is the first place you should look.

They all look the same. They start out with great tests, verifying that the simplest CRUD operations are covered. Then as the changes come, the tests fade away. Their big browser-driven tests are so slow, brittle, and difficult, the question of "should we test this?" becomes paramount as they try to convince themselves that their code doesn't need tests. And even the most ardent TDD proponents and green-band wearers are suffocated as they have to admit that, yes, for the business' sake we cannot spend days building a test harness to test if a new field is required.

I hope this article is the myth-buster to the fantasy world that the Rails community takes testing seriously.
