I am working with a PhD student at CERN on distributed testing,  and
there is a project gridunit that does some good stuff already, running
junit tests across a farm of nodes, collecting and presenting the
results.

Wow, that sounds really cool! Especially as there's a grid already in place
(http://www.lsd.ufcg.edu.br/~alex/doku.php?id=gridunit).

yes, the grid is there. current gridunit can run a jar full of junit tests across many machines, I/we want to extend that to do testing of distributed systems, where you bring up some machines with your app then run the tests from a long way away.

There is also planetlab (http://planetlab.org), which is a large soup of random boxes out there, with random network QoS. Its there to let students/researchers test on a real network, not a simulation.


Is there an integration with a CI already in place? (I'd love to try it out
for building Cargo - It has lots of tests and this would help a lot).

oh, no, nothing yet from my work. Talk to Alex about what he has done. I am part way through a cargo component for smartfrog though, also on my todo list is something to deploy cruise control itself.

what we actually do at work is just run cruise control on a single box and collect the results. Its that result collection which becomes critical and hard on a big distributed system.


Some time back I had blogged about distributed build
(http://tinyurl.com/42zc7). This is still something I'd love to do. I agree
that distributed test is a different topic than distributed build but
combining the two would be even greater... ;-)

I havent looked at distributed builds much. Smartfrog can actually deploy any Ant task, so you could write your build in the language, though nobody does; we just use the tasks to avoid writing so many utilities ourselves, though when we do do the latter we get to implement cleanup on undeploy.
