'''Tree testing''' is a [[usability]] technique for evaluating the [[findability]] of topics in a [[website]].<ref name=TsT1>{{Cite book |last=Hanington |first=Bruce |title=Universal Methods of Design, Expanded and Revised |last2=Martin |first2=Bella |publisher=Rockport Publishers |year=2019 |isbn=9781631597497 |___location=Beverly, MA |pages=232 |language=en}}</ref> It is also known as '''[[card sorting#Reverse card sorting|reverse card sorting]]''' or '''card-based classification'''.<ref name="CBC article" >{{cite web

A large website is typically organized into a hierarchy (a "tree") of topics and subtopics.<ref>{{Cite book |last=Chesnut |first=Donald |title=UX for dummies |last2=Nichols |first2=Kevin |publisher=[[Wiley (publisher)|Wiley]] |year=2014 |isbn=9781118852781 |___location=West Sussex, England |pages=141 |language=English}}</ref><ref>{{Cite book |last=Palade |first=Vasile |title=Knowledge-based Intelligent Information and Engineering Systems. |publisher=Springer Nature |year=2003 |isbn=978-3-540-23318-3 |pages=250 |language=English}}</ref> Tree testing provides a way to measure how well users can find items in this hierarchy.<ref>{{Cite book |last=Elleithy |first=Khaled |title=Advances in Systems, Computing Sciences and Software Engineering : Proceedings of SCSS 2005 |last2=Sobh |first2=Tarek |publisher=Springer |year=2006 |isbn=9781402052620 |___location=Dordrecht |pages=232 |language=en}}</ref><ref>{{Cite book |last=Paraguacu |first=Fabio |title=Intelligent tutoring systems : 6th International Conference, ITS 2002, Biarritz, France and San Sebastián, Spain, June 2-7, 2002 : proceedings |last2=Gouarderes |first2=Guy |last3=Cerri |first3=Stefano A. |publisher=Springer |year=2002 |isbn=978-3-540-43750-5 |___location=Berlin; London |pages=743 |language=English}}</ref>
Unlike traditional [[usability testing]], tree testing is not done on the website itself; instead, a simplified text version of the site structure is used.<ref name=TsT1 /> This ensures that the structure is evaluated in isolation, nullifying the effects of navigational aids, [[visual design]], and other factors.<ref>{{Cite book |last=DESAI |first=SANDEEP |title=Software Testing |last2=SRIVASTAVA |first2=ABHISHEK |publisher=Phi Learning |year=2016 |isbn=9788120352261 |pages=310 |language=en}}</ref>

Tree testing was originally done on paper (typically using [[index cards]]), but can now also be conducted using specialized software.<ref>{{Cite book
