I'm not sure why you made thos class attributes...

It sucks having to reinvent the regex here :(

It seems it's almost more work to use z3c.testsetup than just writing  
down an old school test_suite() function. It'd be nice if  
z3c.testsetup could work with arbitrary layers, like I've suggested in  
my reply to Uli.
