The results directory compress fairly well. A complete ext4 run (with
the configurations defined for gce-xfstests) is 101MB uncompressed,
and 2.3 MB as a tar.xz file. That's only 6 cents a month in Google
Cloud Storage, and for me it's worth it to keep them; it's
occasionally been interesting.

Yes, it does.

It does include some information, but not all of the information that
might be in the results directory.

I do this. You can see an example here with my annotations:

Yep, I do this by using a command-line option when I run gce-xfstests
or kvm-xfstests to skip using the exclude files. It's definitely
useful.

I have some scripts which you may find useful. They can be found here:
https://github.com/tytso/xfstests-bld/tree/master/kvm-xfstests/test-appliance/files/usr/local/bin
https://github.com/tytso/xfstests-bld/tree/master/kvm-xfstests/test-appliance/files/usr/lib/python2.7
This is what I use to parse through the xunit xml files to generate

There are software packages that will process xunit XML files, store
them into a database and then generate reports against a defined
baseline. They'll also do fancy graphs, and some of them will show
flakey tests, etc. I haven't had time to investigate them, though,
but if you do find some cool tools to process the xunit files, I'd
definitely be interested.
