On the Ruby Rogues podcast I mentioned that I had moved away from Cucumber to RSpec and Capybara for my integration tests. Here’s a demo on how to do some TDD with RSpec and Capybara.

RSpec gives us many powerful tools to make our tests readable. Matchers allow us to provide custom predicates to our should statements that succinctly define the behavior of our code.

Shoulda is a framework that sits on top of Test::Unit and adds a ton of nice features like macro’s, nested context, and the ability to create custom tests in a block-based DSL.

This is a basic introduction to integration testing with cucumber. In it, I describe how to use cucumber and rspec to implement a feature in a web application, emphasizing the importance of writing tests before code, which is often referred to as TDD (test-driven development) or BDD (behavior-driven development, a refinement of the original TDD).
