Behaviour Driven Development for Ruby
rspec is a meta-gem, which depends on the rspec-core, rspec-expectations
and rspec-mocks gems. Each of these can be installed separately and loaded in
require. 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
it) but prefer Test::Unit assertions and mocha, rr
or flexmock for mocking, you'll be able to do that without having to install or load the
components of RSpec that you're not using.
See http://rspec.info/documentation/ for links to documentation for all gems.
