<p>The <b>RubySpec</b> project aimed to write a complete executable specification for the <a href="Ruby_(programming_language)" title="Ruby (programming language)">Ruby programming language</a>. This project contains specs that describe Ruby language syntax and <a href="Standard_library" title="Standard library">standard library</a> classes. The project contains two main components:
</p>
<ul><li>the RubySpec sources</li>
<li>the MSpec framework</li></ul>
<p>The RubySpec test suite captured most of 1.8.6/1.8.7/1.9 behavior as a reference conformance tool. <a href="Ruby_MRI" title="Ruby MRI">Ruby MRI</a> 1.9.2 passed over 99% of RubySpec,<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> while version 2.2.0 crashed on one of the tests.<sup id="cite_ref-discont_2-0" class="reference"><a href="#cite_note-discont-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup>
</p>
<div class="mw-heading mw-heading2"><h2 id="History">History</h2></div>
<p>The RubySpec tests were initially created in 2006 for the <a href="Rubinius" title="Rubinius">Rubinius</a> project, with significant contribution from the <a href="JRuby" title="JRuby">JRuby</a> project.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> It is now used in other Ruby implementation projects such as <a href="IronRuby" title="IronRuby">IronRuby</a>.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup>
The RubySpec project was discontinued at the end of 2014 due to a lack of uptake from mainstream ruby developers.<sup id="cite_ref-discont_2-1" class="reference"><a href="#cite_note-discont-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup>
