RSpec
RSpec is a framework to test Ruby code that allows you to use a domain-specific language to provide tests, much in the same way Chef provides a domain-specific language to manipulate an infrastructure. Instead of using a DSL to manage systems, RSpec's DSL provides a number of components to express the expectations of code and simulate the execution of portions of the system (also known as mocking).

# simple expectation it 'should add 2 and 2 together' do x = 2 + 2 expect(x).to eq 4 end # Ensure any instance of Object receives a call to 'foo' # and return a pre-defined value (mocking) it 'verifies that an instance receives :foo' do expect_any_instance_of(Object) ...
