rspec-rails extends Rails' built-in testing framework to support rspec examples for requests, controllers, models, views, helpers, mailers and routing.
rspec-rails-2 supports rails-3.0.0 and later. For earlier versions of Rails, you need rspec-rails-1.3.
gem install rspec-rails
This installs the following gems:
rspec
rspec-core
rspec-expectations
rspec-mocks
rspec-rails
Add rspec-rails to the :test and :development groups in the Gemfile:
group :test, :development do
gem "rspec-rails", "~> 2.0.1"
end
It needs to be in the :development group to expose generators and rake tasks without having to type RAILS_ENV=test.
Now you can run:
script/rails generate rspec:install
This adds the spec directory and some skeleton files, including a .rspec file.
You can choose between webrat or capybara for simulating a browser, automating a browser, or setting expectations using the matchers they supply. Just add your preference to the Gemfile:
gem "webrat"
gem "capybara"
Note that Capybara matchers are not available in view or helper specs.
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.
