6 - cd into the xfstests directory
11 - cd into the xfstests directory
12 - set the ROOT and TOOLROOT env variables for IRIX appropriately
15 ______________________
17 ______________________
19 Preparing system for tests (IRIX and Linux):
21 - compile XFS into your kernel or load XFS modules
22 - install user tools including mkfs.xfs, xfs_db & xfs_bmap
23 - If you wish to run the udf components of the suite install
24 mkfs_udf and udf_db for IRIX and mkudffs for Linux. Also download and
25 build the Philips UDF Verification Software from
26 http://www.extra.research.philips.com/udf/, then copy the udf_test
27 binary to xfstests/src/. If you wish to disable UDF verification test
28 set the environment variable DISABLE_UDF_TEST to 1.
31 - create one or two partitions to use for testing
33 - format as XFS, mount & optionally populate with
35 - one SCRATCH partition (optional)
36 - leave empty and expect this partition to be clobbered
37 by some tests. If this is not provided, many tests will
39 (SCRATCH and TEST must be two DIFFERENT partitions)
41 - for btrfs only: some btrfs test cases will need 3 or more independent
42 SCRATCH disks which should be set using SCRATCH_DEV_POOL (for eg:
43 SCRATCH_DEV_POOL="/dev/sda /dev/sdb /dev/sdc") with which
44 SCRATCH_DEV should be unused by the tester, and for the legacy
45 support SCRATCH_DEV will be set to the first disk of the
46 SCRATCH_DEV_POOL by xfstests script.
48 - setup your environment
49 - setenv TEST_DEV "device containing TEST PARTITION"
50 - setenv TEST_DIR "mount point of TEST PARTITION"
52 - setenv SCRATCH_DEV "device containing SCRATCH PARTITION" OR
53 (btrfs only) setenv SCRATCH_DEV_POOL "to 3 or more SCRATCH disks for
54 testing btrfs raid concepts"
55 - setenv SCRATCH_MNT "mount point for SCRATCH PARTITION"
56 - setenv TAPE_DEV "tape device for testing xfsdump"
57 - setenv RMT_TAPE_DEV "remote tape device for testing xfsdump"
58 - setenv RMT_IRIXTAPE_DEV "remote IRIX tape device for testing xfsdump"
59 - setenv SCRATCH_LOGDEV "device for scratch-fs external log"
60 - setenv SCRATCH_RTDEV "device for scratch-fs realtime data"
61 - setenv TEST_LOGDEV "device for test-fs external log"
62 - setenv TEST_RTDEV "device for test-fs realtime data"
63 - if TEST_LOGDEV and/or TEST_RTDEV, these will always be used.
64 - if SCRATCH_LOGDEV and/or SCRATCH_RTDEV, the USE_EXTERNAL
65 environment variable set to "yes" will enable their use.
66 - setenv DIFF_LENGTH "number of diff lines to print from a failed test",
67 by default 10, set to 0 to print the full diff
68 - or add a case to the switch in common/config assigning
69 these variables based on the hostname of your test
71 - or add these variables to a file called local.config and keep that
72 file in your workarea.
74 - if testing xfsdump, make sure the tape devices have a
75 tape which can be overwritten.
77 - make sure $TEST_DEV is a mounted XFS partition
78 - make sure that $SCRATCH_DEV or $SCRATCH_DEV_POOL contains nothing useful
83 - By default the tests suite will run xfs tests:
84 - ./check '*/001' '*/002' '*/003'
86 - You can explicitly specify NFS, otherwise the filesystem type will be
87 autodetected from $TEST_DEV:
88 ./check -nfs [test(s)]
89 - Groups of tests maybe ran by: ./check -g [group(s)]
90 See the 'group' file for details on groups
91 - for udf tests: ./check -udf [test(s)]
92 Running all the udf tests: ./check -udf -g udf
93 - for running nfs tests: ./check -nfs [test(s)]
94 - To randomize test order: ./check -r [test(s)]
97 The check script tests the return value of each script, and
98 compares the output against the expected output. If the output
99 is not as expected, a diff will be output and an .out.bad file
100 will be produced for the failing test.
102 Unexpected console messages, crashes and hangs may be considered
103 to be failures but are not necessarily detected by the QA system.

110 Creating new tests scripts:
112 Use the "new" script.
114 Test script environment:
116 When developing a new test script keep the following things in
117 mind. All of the environment variables and shell procedures are
118 available to the script once the "common/rc" file has been
121 1. The tests are run from an arbitrary directory. If you want to
122 do operations on an XFS filesystem (good idea, eh?), then do
123 one of the following:
125 (a) Create directories and files at will in the directory
126 $TEST_DIR ... this is within an XFS filesystem and world
127 writeable. You should cleanup when your test is done,
128 e.g. use a _cleanup shell procedure in the trap ... see
129 001 for an example. If you need to know, the $TEST_DIR
130 directory is within the filesystem on the block device
133 (b) mkfs a new XFS filesystem on $SCRATCH_DEV, and mount this
134 on $SCRATCH_MNT. Call the the _require_scratch function
135 on startup if you require use of the scratch partition.
136 _require_scratch does some checks on $SCRATCH_DEV &
137 $SCRATCH_MNT and makes sure they're unmounted. You should
138 cleanup when your test is done, and in particular unmount
140 Tests can make use of $SCRATCH_LOGDEV and $SCRATCH_RTDEV
141 for testing external log and realtime volumes - however,
142 these tests need to simply "pass" (e.g. cat $seq.out; exit
143 - or default to an internal log) in the common case where
144 these variables are not set.
146 2. You can safely create temporary files that are not part of the
147 filesystem tests (e.g. to catch output, prepare lists of things
148 to do, etc.) in files named $tmp.<anything>. The standard test
149 script framework created by "new" will initialize $tmp and
152 3. By default, tests are run as the same uid as the person
153 executing the control script "check" that runs the test scripts.
155 If you need to be root, add a call to the shell procedure
156 _need_to_be_root ... this will do nothing or exit with an
157 error message depending on your current uid.
159 4. Some other useful shell procedures:
161 _get_fqdn - echo the host's fully qualified
164 _get_pids_by_name - one argument is a process name, and
165 return all of the matching pids on
168 _within_tolerance - fancy numerical "close enough is good
169 enough" filter for deterministic
170 output ... see comments in
171 common/filter for an explanation
173 _filter_date - turn ctime(3) format dates into the
174 string DATE for deterministic
177 _cat_passwd, - dump the content of the password
178 _cat_group or group file (both the local file
179 and the content of the NIS database
180 if it is likely to be present)
182 5. General recommendations, usage conventions, etc.:
183 - When the content of the password or group file is
184 required, get it using the _cat_passwd and _cat_group
185 functions, to ensure NIS information is included if NIS
187 - When calling getfacl in a test, pass the "-n" argument so
188 that numeric rather than symbolic identifiers are used in
193 Each test script has a numerical name, e.g. 007, and an associated
194 verified output, e.g. 007.out.
196 It is important that the verified output is deterministic, and
197 part of the job of the test script is to filter the output to
198 make this so. Examples of the sort of things that need filtering:
205 - variable directory contents
206 - imprecise numbers, especially sizes and times
210 The script "check" may be used to run one or more tests.
212 Test number $seq is deemed to "pass" when:
213 (a) no "core" file is created,
214 (b) the file $seq.notrun is not created,
215 (c) the exit status is 0, and
216 (d) the output matches the verified output.
218 In the "not run" case (b), the $seq.notrun file should contain a
219 short one-line summary of why the test was not run. The standard
220 output is not checked, so this can be used for a more verbose
221 explanation and to provide feedback when the QA test is run
225 To force a non-zero exit status use:
231 won't have the desired effect because of the way the exit trap
234 The recent pass/fail history is maintained in the file "check.log".
235 The elapsed time for the most recent pass for each test is kept
