The names of fixtures, methods, inputs, and outputs can be expressed in two forms.
They can match their corresponding names in the fixture classes, or they can be graceful.

A graceful name looks like it is written in human language rather than computer language. It has spaces that separate the words and may have a period at the end.This is a strategy and the exact implementation depends on the type of table being executed. It is better when you define output methods with 'graceful names' to put a ? in the end of the name in order to be specified that it is an output method and not input (set method).
For example, in the case of a Query Table, column names in the front end must exactly match those in the corresponding Fixture. So, it is always helpful to take a closer look at a specific table documentation.

Slim will convert graceful names into the names of the classes and methods they refer to. So for example:

Graceful Name	Fixture Name
slim test	SlimTest
login user.	LoginUser
Open connection and add user.	OpenConnectionAndAddUser

Graceful Name	Method Name
slim test?	slimTest
login user ?	loginUser
Open connection and add user?	openConnectionAndAddUser

In some cases, fixture names and method names do not follow this convention. For this reason FitNesse will also try the following names:

Graceful Name	Fixture Name
slim test	slimTest
login user.	loginUser
Open connection and add user.	openConnectionAndAddUser

Graceful Name	Method Name
slim test?	SlimTest
login user ?	LoginUser
Open connection and add user?	OpenConnectionAndAddUser
