Behaviour Driven Development for Ruby # RSpec Core rspec-2.x is a meta-gem, which depends on the rspec-core, rspec-expectations and rspec-mocks gems. Each of these can be installed separately and actived in isolation with the `gem` command. Among other benefits, this allows you to use rspec-expectations, for example, in Test::Unit::TestCase if you happen to prefer that style. Conversely, if you like RSpec's approach to declaring example groups and examples (`describe` and `it`) but prefer Test::Unit assertions and mocha, rr or flexmock for mocking, you'll be able to do that without having to load the components of rspec that you're not using. ## Documentation * [Cucumber features](http://relishapp.com/rspec/rspec-core) * [RDoc](http://rubydoc.info/gems/rspec-core/2.4.0/frames)
