How to integrate PHPUnit with zend framework or any other custom php framework?

How to integrate PHPUnit with PHP Pro custom php framework?

I need how to get the framework environment just how we get in Zend Framework.

There are tons of tutorials available for Zend but not for custom framework like PHP Pro

Also PHPUnit does not give example with MVC framework.

Especially for the Zend Framework there is Zend_Test mentioned at the manual.
