Is continuous integration enough? Not... one needs to push the boundaries (paper review)

Pushing the boundaries of continous integration (paper review)
http://dx.doi.org/10.1109/Agile.2008.31

I was asked recently the following question If continous integration is not the last thing to do, what else is there left? which got me thinking.

There is the deployment, sure, but it often is part of another project. Then I thought - testing - and I've looked for articles about test automation and I've found this nice experience report from BT. They extend the CI with robustness testing and durability testing.

This is a really nice example of how to improve CI. What I like about it is the toolsuite which they have evaluated - all open source.
