Framework for integrated test
open-in-new
<p>Framework for Integrated Test (Fit), is an <a href="/facts/Open-source_software/HzTaB8E9">open-source</a> (GNU GPL v2) tool for automated customer tests. It integrates the work of customers, analysts, testers, and developers. </p><p>Customers provide examples of how their software should work. Those examples are then connected to the software with programmer-written <a href="/facts/Test_fixture/cK6KfUVn">test fixtures</a> and automatically checked for correctness. The customers' examples are formatted in tables and saved as <a href="/facts/HTML/sSc3fT78">HTML</a> using ordinary business tools such as <a href="/facts/Microsoft_Excel/Ezal6G75">Microsoft Excel</a>. When Fit checks the document, it creates a copy and colors the tables green, red, and yellow according to whether the software behaved as expected. </p><p>Fit was invented by <a href="/facts/Ward_Cunningham/8SuK946v">Ward Cunningham</a> in 2002. He created the initial Java version of Fit. As of June 2005, it has up-to-date versions for <a href="/facts/Java_(programming_language)/9ScgFyAL">Java</a>, <a href="/facts/C_Sharp_(programming_language)/UC2gxeyb">C#</a>, <a href="/facts/Python_(programming_language)/YbuGqofa">Python</a>, <a href="/facts/Perl/fx31kjlT">Perl</a>, <a href="/facts/PHP/vU6YRJX0">PHP</a> and <a href="/facts/Smalltalk/Ru2UPVDE">Smalltalk</a>. </p><p>Although Fit is an acronym, the word "Fit" came first, making it a <a href="/facts/Backronym/LhorLRMH">backronym</a>. Fit is sometimes italicized but should not be capitalized. In other words, "Fit" and "<i>Fit</i>" are appropriate usage, but "FIT" is not. </p><p>Fit includes a simple <a href="/facts/Command-line_tool/R9JpGmXQ">command-line tool</a> for checking Fit documents. There are third-party front-ends available. Of these, <a href="/facts/FitNesse/8K4ceoRt">FitNesse</a> is the most popular. FitNesse is a complete <a href="/facts/Integrated_development_environment/jbEINSQf">IDE</a> for Fit that uses a Wiki for its front end. As of June 2005, FitNesse had <a href="/facts/Fork_(software)/D6khxhpr">forked</a> Fit, making it incompatible with newer versions of Fit, but plans were underway to re-merge with Fit. </p>
