So go with it. If you want a really convenient way of running xfstests, I have a set of wrapper scripts that make it easy to run xfstests using either KVM or GCE (Google Compute Engine). The idea is to do something which is turn-key and really easy, so that people who are submitting patches for me to review have no excuse not to run tests first. :-) I also was making it easy because there were some graduate students who were interesting writing their own file system or making changes to existing file systems, and this made it easy for them to do their testing. So it was deisgned for that use case as well. For more information, please see these URL's: http://thunk.org/gce-xfstests https://github.com/tytso/xfstests-bld/blob/master/Documentation/kvm-quickstart.md https://github.com/tytso/xfstests-bld/blob/master/Documentation/kvm-xfstests.md https://github.com/tytso/xfstests-bld/blob/master/Documentation/gce-xfstests.md And, for extra fun, we have alpha support for using xfstests in an Android environment. This can be used if you need to test some feature that requires hardware support, such as the ext4 integration with hardware inline-crypto encryption (ICE): https://github.com/tytso/xfstests-bld/blob/master/Documentation/android-xfstests.md (This is rather bleeding edge code, and it's mainly only been tested on a small set of devices. It will also destroy existing user data on the device, and xfstests can use up a large number of write cycles on low-end flash. So I recommend only using android-xfstests on sacrificial development devices where you don't have a strong attachment to any data on the device or the longevity of of said device. :-) Cheers! - Ted P.S. gce-xfstest and kvm-xfstests have support to test file systems beyond ext4, but to date it's been primarily used to test ext4 file system code. I have basic support for btrfs, f2fs, xfs, overlayfs, tmpfs, and it would be trivial to add support for more file systems, or for people who want to give me file system test configurations for file systems beyond ext4. So if you are interested in using kvm-xfstests or gce-xfstests for other filesystems --- please drop me a line and let's chat.
