RubySpec

RubySpec
Written in	Ruby
Type	Ruby programming language specifications tests
Website	www.rubyspec.org

The RubySpec project aimed to write a complete executable specification for the Ruby programming language. This project contains specs that describe Ruby language syntax and standard library classes. The project contains two main components:

the RubySpec sources
the MSpec framework

The RubySpec test suite captured most of 1.8.6/1.8.7/1.9 behavior as a reference conformance tool. Ruby MRI 1.9.2 passed over 99% of RubySpec,[1] while version 2.2.0 crashed on one of the tests.[2]

History

The RubySpec tests were initially created in 2006 for the Rubinius project, with significant contribution from the JRuby project.[3] It is now used in other Ruby implementation projects such as IronRuby.[4] The RubySpec project was discontinued at the end of 2014 due to a lack of uptake from mainstream ruby developers.[2]

It was later revived by Benoit Daloze as "The Ruby Spec Suite", and is as of 2023-08-15 actively maintained at https://github.com/ruby/spec.
