The name of a fitnesse test page begins with "Test", or has the Test attribute set. See Page Attributes. This makes sure that the page will have a Test button.

Fitnesse tests are written in Fit format (http://fit.c2.com ). This format is very simple. The page can contain any text at all. Any tables that exist on the page will be interpreted by Fit.

A Fit table begins with a row that contains the classname of the test fixture that will interpret the rest of the table. Usually you write these test fixtures. There are a number of test fixture base classes that make writing these fixtures very simple.

The rest of the rows in a Fit table have formats that are determined by the fixture.
