stop! .. time for unit tests

Hi,

ok this last bug did it for me ..
we should stop any feature enhancement efforts until we get the unit 
testing stuff worked out.

first we have to pick a tool kit.

1) phpt

AFAIK it currently can only run tests on the shell, which kills testing 
the session handling. though there is supposedly a patch to allow 
testing inside a SAPI as well.

Aside from this its fairly simple and requires little knowledge beyond 
PHP itself once we have a few examples done. Also since its just PHP 
code with a bunch of print statements is very easy to integrate any user 
provided bug reproduce scripts.

2) PHPUnit(2)

I am using PHPUnit for MDB2 based on the initial work  by Paul Cooper. 
It seems to work alright.

3) SimpleTest

I tried it out a while back and I even did some initial unit testing for 
LiveUser once (http://www.backendmedia.com/LiveUser/liveuser_test.zip). 
It also seems to work alright. I just remember that I wanted to do 
something simple and Marcus the lead developer insisted that I jump 
through 3 hoops to get it done.

regards,
Lukas
