Re: Where to place this logic?

Hi Reuben,

for the moment I opted for putting the code into a lib.

So now the next question. How can I wirte tests for it? Can I do that
within the CakePHP testframework? If yes, how do I call it? Is there an
example anywhere?
Or do I have to call phpunit test from the bash?

Any hint helping me to be a good developer girl keeping the promise to
always write tests woulod be appreciated!

Anja
