RSpec Logo
Behaviour Driven
Development for Ruby.
Making TDD Productive and Fun.

Let's get started!

To kick things off, install RSpec and run rspec --init to set up your project to use RSpec.

Start with a very simple example that expresses some basic desired behaviour.

Run the example and watch it fail.

Implement that basic behaviour...

Run the example and bask in the joy that is green.

Take very small steps

Don’t rush ahead with more code. Instead, add another example and let it guide you to what you have to do next. And don’t forget to take time to refactor your code before it gets messy. You should keep your code clean at every step of the way.

Testing Ruby Application with RSpec Screencast

The Screencast

The Testing Ruby Applications with RSpec screencast introduces the core RSpec libraries through the development of a small CLI card game. In addition to covering the technical aspects of using RSpec, it also covers best practices for using them so you get the most out of your test suite: different types of tests, what kinds of things to test, when different styles are appropriate.
