According ot the rules

============
Test program
============

A test program is provided to help screen entries and to provide the Golf Score.
Any program that passes the test program can be submitted. If you are surprised that your solution passed the test program, please submit it anyway! That will help me identify bugs in the test program.



Thus, one can consider the exclusion of e.g. 2, 3, 4 as test cases a bug in the test program. I have also checked with other programming contest sites and the updating of test cases is quite common. I therefore see no reason not to update the test cases in the package. If a solution indeed miscategorizes a number, then is is not solving the problem at hand.

An updated version of the test cases is available at http://s91376351.onlinehome.us/kixtart/kixgolf_happy_numbers.zip

I will update the rules accordingly for the next tournament to explicitly state that the test suite can be amended at any time to provide a greater variety of test cases.
