Fitnesse Viewer is a free Chrome extension developed by Mike Plavsky. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This extension is designed to analyze Fitnesse Slim Test Pages, providing users with valuable insights and information.

Fitnesse Viewer allows users to easily view and analyze scenarios, scripts, query tables, and decision tables on Fitnesse Slim Test Pages. With this extension, users can quickly understand which scenarios are being used, identify any unused scenarios, and determine if there are any external functions being used on the page. This is particularly helpful for users who work with large Scenario Libraries, as it enables them to identify which scenarios could be useful for a specific test.

Once installed, Fitnesse Viewer adds an eye icon to the address bar when users navigate to an Acceptance Test page. By clicking on the eye icon, users can choose to view All Scenarios, Used Scenarios, or Called Functions. Clicking on a specific scenario will display its definition.

It is important to note that Fitnesse Viewer only works for pages that have not been run. Additionally, the feature of invoking a scenario from a script table using Interposed style is not yet available.
