I did write a lot unit tests which I didn't submit (yet) but my main test was 
cross building things like perl 5.14 and running its rather large test suite.   
I also cross built over 8,000 packages for FreeBSD/MIPS64 using Poudrière and 
qemu-mips64 (see 
http://people.freebsd.org/~bapt/pres/modern-package-management.pdf for more 
information).
