What's a good unit test framework for Common Lisp projects?

I need to write a unit test suite for a project I am developing in my spare time. Being a CL newbie I was overwhelmed by the amount of choices for a CL implementation, I spent quite some time to choose one. Now I am facing exactly the same thing with unit test frameworks.

A quick glance at http://www.cliki.net/test%20framework shows 20 unit test frameworks! Choice is good but for a novice like me this can be a bit confusing and given the number of frameworks it would be painful to try them all.

I would like to use a framework which:

Is reasonably well maintained
Easy to use but with some degree of flexibility
Offers some sort of integration with Emacs (or it is possible to easily integrate it with Emacs)
It is possible to integrate it with git post-commit hooks
It is possible to integrate it with a continous integration system (such as buildbot)

What are your experiences in this field?

Did you see the link to http://aperiodic.net/phil/archives/Geekery/notes-on-lisp-testing-frameworks.html off the Test framework link on that cliki page you mention? Phil gives his impressions, and what it looks like to use the various test frameworks.
