xfstests has gone pretty far beyond just xfs at this point - it's seen
heavy use on ext2/3/4 as well as btrfs in the past several years.

There is a README in the git repo; did you have specific questions?

We have a lot of tests in there; some are general stress tests, some
are specific regression tests, and the body of tests is always growing.

Some test IO failures, as well.  File system consistency is checked after
each test.  Etc...
