rspec-rails extends Rails' built-in testing framework to support rspec examples for requests, controllers, models, views, and helpers.
rspec-rails-2 supports rails-3.0.0 and later. For earlier versions of Rails, you need rspec-rails-1.3.
The documentation for rspec-rails is a work in progress. We'll be adding Cucumber features over time, and clarifying existing ones. If you have specific features you'd like to see added, find the existing documentation incomplete or confusing, or, better yet, wish to write a missing Cucumber feature yourself, please submit an issue or a pull request.
