Hi,

Xfstests uses several environment variants to setup the test environment.
You can set it manually using export, or write them into local.conf in xfstests directory.

These environment variants are mandatory:
TEST_DEV: device for normal tests, like all generic tests
TEST_DIR: where TEST_DEV is mounted to.

And somecommon optional environment variants:
SCRATCH_DEV: scratch device for some tests, if you want to test btrfs' multi device related feature, you need
to set SCRATCH_DEV_POOL.
SCRATCH_DEV_POOL: a list for devices mainly for btrfs' muti-device related test.
SCRATCH_MNT: where SCRATCH_DEV/SCRATCH_DEV_POOL is mounted to.

SCRATCH_DEV_POOL should not contain the TEST_DEV.

FSTYP: the filesystem type you want to test.
MKFS_OPTIONS: the mkfs time options. Useful to test mkfs time feature like no-holes.
MOUNT_OPTIONS: the mount time options. Useful to test feature like compress.

So short guide on how to run xfstests:
1. download the xfstests source, better the git version

2. compile xfstests
make will do everything for you, except you lacks some headers or dependency.
When that happens, follow your distribution's method to install them.

3. setup the environment variants
Manually or into the local.conf is both OK.

4. run tests
You can run all tests by ./check -g auto, or multiple/single test using blob/testcase number like:
# ./check generic/311
# ./check btrfs/[0-9][0-9][0-9]

Thanks
Qu

Hey Fellow Btrfs Developers,
I am wondering how to run the xfs tests for btrfs as I tried to do it based on a link online
written I believe a few years ago. If someone can help me get set up for testing the btrfs
code using xfs tests that would be great. In addition afterwards I already build kernel 3.17
r5 release candidate and would be glad to run any times you need run to test single drive
config issues.
Thanks Nick

The issue I was hitting was my TEST_DIR not being configured properly. I will list my variables below.
/dev/sdc1 was my TEST_DEV
/media/nick/x was my TEST_DIR
Nick

Did you mkfs on TEST_DEV? Can TEST_DEV be mounted correctly?

Thanks,
Qu

I partitioned  it using gparted and I can mount it normally but not with xfstests.
Nick

Did you specify the FSTYP? and what's the error prompt and dmesg for the 
fail of mount?

Thanks,
Qu
