I'd like to test the correctness and the completeness of an implementation of the BSP API. The test set has to be cross-compiled for an ARM sam7x.
I don't know if this would be of any interest to you, but here are two links to presentations from NYC BSD Conference 2008: Detecting TCP regressions with tcpdiff (FreeBSD) and An introduction to the Automated Testing Framework (ATF) for NetBSD. Both were pretty good.
