Introduction
FitNesse is a tool for specifying and verifying application acceptance criteria (requirements). It acts as a bridge between the different stakeholders (disciplines) in a software delivery process. Its wiki server makes it easy to document the software. Its test-execution capabilities allow you to verify the documentation against the software, ensuring the documentation remains up to date and the software is not facing regression.
For this to work, the tests should be defined on a business level, in conjunction with business representatives. They are basically business requirements, laid out in a way easy to understand by all stakeholders. When your requirements are unambiguous, they can be automatically verified with your application.
To make it easy for all stakeholders to interact with FitNesse, requirements can be created and edited through the web browser. It's a wiki! By writing specifications (also known as Acceptance Tests), you can create a common understanding among the team (coders and non-coders). This helps tremendously in delivering the right system. Specifications can be written in wiki syntax or in a rich text editor, so no knowledge of the wiki syntax is required.
Because the specifications can actually be executed, FitNesse provides a method to demonstrate even to non-coders that the application works as designed. This can prevent problems leading to Project Death by Requirements. The goal is for FitNesse to operate at a level just below the user interface level, demonstrating that, given various inputs to your application, the correct results are computed. In a sense, you could consider it an alternative user interface for the application.

Brief history
FitNesse started as an HTML and wiki "front-end" to FIT ("Framework for Integrated Testing") back in 2001.From the Fit website:
Great software requires collaboration and communication.Fit is a tool for enhancing collaboration in software development. It's an invaluable way to collaborate on complicated problems -and get them right- early in development.
Fit allows customers, testers, and programmers to learn what their software should do and what it does do. It automatically compares customers' expectations to actual results.
Nowadays FitNesse is a comprehensive tool, supports multiple test systems, and has been used for many software and even hardware projects.
