pyUnit unit testing for Magento a good idea?

Today it was suggested to me to use PyUnit with our Magento modules because of its request and response objects. Is there any advantage to using an xUnit testing framework?

We would be running Hudson as the CI wit开发者_Python百科h Maven along with some PHPUnit and Selenium Tests. I am currently using the Request and Response controllers from Zend Framework in PHPUnit.
