I wrote something Pythonic and minimalistic, but I'm not sure if it does what you want... then again it can always be extended. It's called Testipy and can be found in my download section. (http://zephyrfalcon.org/download/) If you want, drop me an email so we can discuss what features you would find useful. If I agree, I might add them. :-)
I wrote Testipy because unittest got in my way a few times, so I decided to make my own little testing framework. I'm using it now for some of my personal projects.
