[CALUG] OSS recommendation

[Jason C. Miller]

Hey, all!

I would like to set up a continuous integration server for demonstration 
purposes and I am looking for a piece of OSS that I can use as an example 
project. The reason for this is that I would like a semi-mature piece of 
software to show off as opposed to writing my own useless sample code.

I'm looking for something simple(ish), graphical, and most importantly, 
something that comes with unit/integration tests.  As an example, 
something like PuTTY would be ideal, but it doesn't come with any real 
unit/integration tests.

Does anyone know of any OSS out there that would fit the bill?
