Fitnesse Variables is a free Chrome add-on developed by Mike Plavsky. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory. This program allows users to view all the variables that affect a particular test page.

With Fitnesse Variables, users can easily see the number and values of all the variables that influence a test page. It analyzes the pages through the ?edit command and displays all the variables found, even if they are defined multiple times. This feature is particularly helpful in identifying any potential issues or understanding the different definitions of a variable.

This add-on provides a convenient way to view all the variables in a single place, which is not possible with the standard Fitnesse tool. It can be a valuable resource for developers and testers who need a comprehensive overview of the variables affecting their test pages.
