There's not much there but a few documents, but there's a new eclipse sub-project called Hyades which looks interesting. Quite a few different companies contributing to it. Its aiming to be a universal functional and integration testing suite thats integrated into eclipse. Its gonna be interesting to see how this stuff fits together and if it can reuse existing testing tools like JUnit, Cactus, Latka, Anteater etc.
Up to now my thoughts on this area have been to integrate something like werkflow, Jelly, Ant and Axis together to make a testing workflow system together with a server farm and collection facality, maybe integrated with the Continuous Integration features of Maven or CruiseControl. There's a new Maven project called Continuum which could well provide the backbone of this suite.
It'll be interesting to see how the Hyades folks tackle the data collection, workflow and scripting aspects of integration testing.
Update: also found this paper which is worth a read.
