But not the tests. How possibly can you use the inheritance of 
APACHE_TEST_CONFIGURE, when it's a true function that does a setup of 
something that's *always* being run before any tests are getting 
executed. If you inherit this function, you will run exactly the same 
code, because the API doesn't pass anything but the config object. but 
then you run this function anyway.

Please give me a single example where you may want to inherit from 
APACHE_TEST_CONFIGURE. I can hardly imagine which good use some other 
class may have from inheriting this function.

I think that $self->$cv is valid too, since you have a ref to the sub 
already. So here you get to call $cv as a method.

sure, I agree. I just thought that APACHE_TEST_* subs will be all 
functions and not OO methods, therefore I think that passing $module is 
just confusing.

But if you think it may be of use in the future, sure let's keep it that
