The RubySpec project aims to write a complete executable specification for the Ruby programming language

Ruby (programming language)

Ruby is a dynamic, reflective, general-purpose object-oriented programming language that combines syntax inspired by Perl with Smalltalk-like features. Ruby originated in Japan during the mid-1990s and was first developed and designed by Yukihiro "Matz" Matsumoto...

. This project contains specs that describe Ruby language syntax and standard library

Standard library

A standard library for a programming language is the library that is conventionally made available in every implementation of that language. In some cases, the library is described directly in the programming language specification; in other cases, the contents of the standard library are...

 classes. The project contains two main components:

• the RubySpec sources
• the MSpec framework

The RubySpec test suite captures most of 1.8.6/1.8.7/1.9 behavior as a reference conformance tool. Ruby MRI

Ruby MRI

Matz's Ruby Interpreter or Ruby MRI is the reference implementation of the Ruby programming language. As there is currently no specification of the Ruby language, the MRI implementation is considered the de facto reference. The RubySpec project has created a large test suite that captures...

 1.9.2 currently passes over 99% of RubySpec.

History

The RubySpec tests were initially created in 2006 for the Rubinius

Rubinius

Rubinius is an alternative Ruby programming language implementation created by Evan Phoenix. Based loosely on the Smalltalk-80 Blue Book design, Rubinius seeks to"provide a rich, high-performance environment for running Ruby code."-Goals:...

JRuby

JRuby is a Java implementation of the Ruby programming language, being developed by the JRuby team. It is free software released under a three-way CPL/GPL/LGPL license...

IronRuby

IronRuby is an implementation of the Ruby programming language targeting Microsoft .NET framework. It is implemented on top of the Dynamic Language Runtime , a library running on top of the Common Language Infrastructure that provides dynamic typing and dynamic method dispatch, among other things,...
