   3 1) Building and installing the ZFS Test Suite
   4
   5 The ZFS Test Suite runs under the test-runner framework.  This framework
   6 is built along side the standard ZFS utilities and is included as part of
   7 zfs-test package.  The zfs-test package can be built from source as follows:
   8
   9     $ ./configure
  10     $ make pkg-utils
  11
  12 The resulting packages can be installed using the rpm or dpkg command as
  13 appropriate for your distributions.  Alternately, if you have installed
  14 ZFS from a distributions repository (not from source) the zfs-test package
  15 may be provided for your distribution.
  16
  17     - Installed from source
  18     $ rpm -ivh ./zfs-test*.rpm, or
  19     $ dpkg -i ./zfs-test*.deb,
  20
  21     - Installed from package repository
  22     $ yum install zfs-test
  23     $ apt-get install zfs-test
  24
  25 2) Running the ZFS Test Suite
  26
  27 The pre-requisites for running the ZFS Test Suite are:
  28
  29   * Three scratch disks
  30     * Specify the disks you wish to use in the $DISKS variable, as a
  31       space delimited list like this: DISKS='vdb vdc vdd'.  By default
  32       the zfs-tests.sh sciprt will construct three loopback devices to
  33       be used for testing: DISKS='loop0 loop1 loop2'.
  34   * A non-root user with a full set of basic privileges and the ability
  35     to sudo(8) to root without a password to run the test.
  36   * Specify any pools you wish to preserve as a space delimited list in
  37     the $KEEP variable. All pools detected at the start of testing are
  38     added automatically.
  39   * The ZFS Test Suite will add users and groups to test machine to
  40     verify functionality.  Therefore it is strongly advised that a
  41     dedicated test machine, which can be a VM, be used for testing.
  42
  43 Once the pre-requisites are satisfied simply run the zfs-tests.sh script:
  44
  45     $ /usr/share/zfs/zfs-tests.sh
  46
  47 Alternately, the zfs-tests.sh script can be run from the source tree to allow
  48 developers to rapidly validate their work.  In this mode the ZFS utilities and
  49 modules from the source tree will be used (rather than those installed on the
  50 system).  In order to avoid certain types of failures you will need to ensure
  51 the ZFS udev rules are installed.  This can be done manually or by ensuring
  52 some version of ZFS is installed on the system.
  53
  54     $ ./scripts/zfs-tests.sh
  55
  56 The following zfs-tests.sh options are supported:
  57
  58     -v          Verbose zfs-tests.sh output When specified additional
  59                 information describing the test environment will be logged
  60                 prior to invoking test-runner.  This includes the runfile
  61                 being used, the DISKS targeted, pools to keep, etc.
  62
  63     -q          Quiet test-runner output.  When specified it is passed to
  64                 test-runner(1) which causes output to be written to the
  65                 console only for tests that do not pass and the results
  66                 summary.
  67
  68     -x          Remove all testpools, dm, lo, and files (unsafe).  When
  69                 specified the script will attempt to remove any leftover
  70                 configuration from a previous test run.  This includes
  71                 destroying any pools named testpool, unused DM devices,
  72                 and loopback devices backed by file-vdevs.  This operation
  73                 can be DANGEROUS because it is possible that the script
  74                 will mistakenly remove a resource not related to the testing.
  75
  76     -k          Disable cleanup after test failure.  When specified the
  77                 zfs-tests.sh script will not perform any additional cleanup
  78                 when test-runner exists.  This is useful when the results of
  79                 a specific test need to be preserved for further analysis.
  80
  81     -f          Use sparse files directly instread of loopback devices for
  82                 the testing.  When running in this mode certain tests will
  83                 be skipped which depend on real block devices.
  84
  85     -c          Only create and populate constrained path
  86
  87     -I NUM      Number of iterations
  88
  89     -d DIR      Create sparse files for vdevs in the DIR directory.  By
  90                 default these files are created under /var/tmp/.
  91
  92     -s SIZE     Use vdevs of SIZE (default: 4G)
  93
  94     -r RUNFILE  Run tests in RUNFILE (default: linux.run)
  95
  96     -t PATH     Run single test at PATH relative to test suite
  97
  98     -T TAGS     Comma separated list of tags (default: 'functional')
  99
 100     -u USER     Run single test as USER (default: root)
 101
 102
 103 The ZFS Test Suite allows the user to specify a subset of the tests via a
 104 runfile or list of tags.
 105
 106 The format of the runfile is explained in test-runner(1), and
 107 the files that zfs-tests.sh uses are available for reference under
 108 /usr/share/zfs/runfiles. To specify a custom runfile, use the -r option:
 109
 110     $ /usr/share/zfs/zfs-tests.sh -r my_tests.run
 111
 112 Otherwise user can set needed tags to run only specific tests.
 113
 114 3) Test results
 115
 116 While the ZFS Test Suite is running, one informational line is printed at the
 117 end of each test, and a results summary is printed at the end of the run. The
 118 results summary includes the location of the complete logs, which is logged in
 119 the form `/var/tmp/test_results/[ISO 8601 date]`.  A normal test run launched
 120 with the `zfs-tests.sh` wrapper script will look something like this:
 121
 122     $ /usr/share/zfs/zfs-tests.sh -v -d /tmp/test
