[cgiapp] CGI::Application Testing Methodologies

[Jason Purdy]

Hi Mark,

This is a great topic and we have discussed it before on this list (we 
should really update the wiki page).

That said, writing webapp tests are really hard these days, what with 
AJAX and other JavaScript niceties not being supported in WWW::Mech. 
Then there's the spectrum of which layer do you want to test on? 
Library layer, CGIApp layer, Apache layer or web browser layer.

My advice would be to factor your code such that the code is separated 
into a testable module.  If your delete_customer function works as 
expected, then all the layers above should work as well since those 
layers are independently tested.

My advice goes without reading the previously touted Testing book, which 
I plan on reading at some point.  My advice also goes without seeing 
mpeters' response, which if he does, will offer more truth and 
experience. :)
