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 isolation using 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
examples (describe and it) but prefer Test::Unit assertions and
mocha, [rr] (https://github.com/btakita/rr)
or [flexmock] (https://github.com/jimweirich/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.
