Create the FitNesse wiki page
Begin by creating your first wiki page (follow the instructions on fitnesse.org on how to create a sub-page of the home page of the wiki).
Edit the wiki pages properties so that it is a test page.
In this new page add the following wiki markup text
!contents -R2 -g -p -f -h
#!define COMMAND_PATTERN {java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=1044 -cp %p %m}
!define TEST_SYSTEM {slim}

${maven.classpath}

Lines 5 - 7: specify the path where the classes can be found if you are doing a maven build
Line 8: specifies the path where the jar file can be located if you want to be explicit about the target to be tested
Line 11: specifies that you are going to indicate the namespace (packages in Java, namespace in .net, namespace in C++) where the SUT can be found
Line 12: the package/namespace name
Line 14: the fixture class name
Line 15: the parameter field names, no question mark 
represents an input field, a field name followed by a question mark represents an output field
Line 16 onwards: the input and expected output values
Remember
Don't try and create all the tests in one go. Define a set of test like the ones above, implement them (RED, GREEN, REFACTOR), then add more tests.
