So it&#x27;s doctest [0] from python?<p>Is the testing framework at amazon open sourced? I really like doctest and wish there were more implementations of this for other languages.<p>If not, than that is unfortunate. If I can&#x27;t see the implementation of something, then I don&#x27;t really consider it &quot;tangible,&quot; so that makes a lot of this &quot;academic-enriched&quot; information unusable for me.<p>[0] <a href="https:&#x2F;&#x2F;docs.python.org&#x2F;2&#x2F;library&#x2F;doctest.html" rel="nofollow">https:&#x2F;&#x2F;docs.python.org&#x2F;2&#x2F;library&#x2F;doctest.html</a>
