Megatest Config File Settings
-----------------------------
Trim trailing spaces
~~~~~~~~~~~~~~~~~~~~
------------------
[configf:settings trim-trailing-spaces yes]
------------------
Submit jobs to Host Types based on Test Name
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.In megatest.config
------------------------
[host-types]
general nbfake
remote bsub
[launchers]
runfirst/sum% remote
% general
[jobtools]
launcher bsub
# if defined and not "no" flexi-launcher will bypass launcher unless there is no
# match.
flexi-launcher yes
------------------------
host-types
^^^^^^^^^^
List of host types and the commandline to run a job on that host type.
.host-type => launch command

^^^^^^^^^
.test/itempath => host-type

Miscellaneous Setup Items
^^^^^^^^^^^^^^^^^^^^^^^^^
Attempt to rerun tests in "STUCK/DEAD", "n/a", "ZERO_ITEMS" states.
.In megatest.config
------------------
[setup]
reruns 5
------------------
The testconfig File
-------------------
Setup section
~~~~~~~~~~~~~
Header
^^^^^^
-------------------
[setup]
-------------------
The runscript method is a brute force way to run scripts where the
user is responsible for setting STATE and STATUS
-------------------
runscript main.csh
-------------------
Requirements section
~~~~~~~~~~~~~~~~~~~~
Header
^^^^^^
-------------------
[requirements]
-------------------
Wait on Other Tests
^^^^^^^^^^^^^^^^^^^
-------------------
# A normal waiton waits for the prior tests to be COMPLETED
# and PASS, CHECK or WAIVED
waiton test1 test2
-------------------
Mode
^^^^
The default (i.e. if mode is not specified) is normal. All pre-dependent tests
must be COMPLETED and PASS, CHECK or WAIVED before the test will start
-------------------
[requirements]
mode normal
-------------------
The toplevel mode requires only that the prior tests are COMPLETED.
-------------------
[requirements]
mode toplevel
-------------------
A item based waiton will start items in a test when the same-named
item is COMPLETED and PASS, CHECK or WAIVED in the prior test. This
was historically called "itemwait" mode. The terms "itemwait" and
"itemmatch" are synonyms.
-------------------
[requirements]
mode itemmatch
-------------------
Itemmap
^^^^^^^
For cases were the dependent test has a similar but not identical
itempath to the downstream test an itemmap can allow for itemmatch
mode
-------------------
[requirements]
mode itemmatch
itemmap .*x/ y/
# ## pattern replacement notes
#
# ## Example
# ## Remove everything up to the last /
itemmap .*/
#
# ## Example
# ## Replace foo/ with bar/
itemmap foo/ bar/
-------------------
.Autogeneration waiton list for dynamic flow dependency trees
-------------------
[requirements]
# With a toplevel test you may wish to generate your list
# of tests to run dynamically
#
# waiton #{shell get-valid-tests-to-run.sh}
-------------------
Run time limit
^^^^^^^^^^^^^^
-----------------
runtimelim 1h 2m 3s # this will automatically kill the test if it runs for more than 1h 2m and 3s
-----------------
Skip
^^^^
A test with a skip section will conditional skip running.
.Skip section example
-----------------
[skip]
prevrunning x
# rundelay 30m 15s
-----------------
Skip on Still-running Tests
^^^^^^^^^^^^^^^^^^^^^^^^^^^
-----------------
# NB// If the prevrunning line exists with *any* value the test will
# automatically SKIP if the same-named test is currently RUNNING. The
# "x" can be any string. Comment out the prevrunning line to turn off
# skip.
[skip]
prevrunning x
-----------------
Skip if a File Exists
^^^^^^^^^^^^^^^^^^^^^
-----------------
[skip]
fileexists /path/to/a/file # skip if /path/to/a/file exists
-----------------
Skip if test ran more recently than specified time
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.Skip if this test has been run in the past fifteen minutes and 15 seconds.
-----------------
[skip]
rundelay 15m 15s
-----------------
Disks
^^^^^
A disks section in testconfig will override the disks section in
megatest.config. This can be used to allocate disks on a per-test or per item
basis.
Controlled waiver propagation
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
If test is FAIL and previous test in run with same MT_TARGET is WAIVED then apply the following rules from the testconfig:
If a waiver check is specified in the testconfig apply the check and if it passes then set this FAIL to WAIVED
Waiver check has two parts, 1) a list of waiver, rulename, filepatterns and 2) the rulename script spec (note that "diff" and "logpro" are predefined)
-----------------
###### EXAMPLE FROM testconfig #########
# matching file(s) will be diff'd with previous run and logpro applied
# if PASS or WARN result from logpro then WAIVER state is set
#
[waivers]
# logpro_file rulename input_glob
waiver_1 logpro lookittmp.log
[waiver_rules]
# This builtin rule is the default if there is no <waivername>.logpro file
# diff diff %file1% %file2%
# This builtin rule is applied if a <waivername>.logpro file exists
# logpro diff %file1% %file2% | logpro %waivername%.logpro %waivername%.html
-----------------
Ezsteps
~~~~~~~
.Example ezsteps with logpro rules
-----------------
[ezsteps]
lookittmp ls /tmp
[logpro]
lookittmp ;; Note: config file format supports multi-line entries where leading whitespace is removed from each line
;; a blank line indicates the end of the block of text
(expect:required in "LogFileBody" > 0 "A file name that should never exist!" #/This is a awfully stupid file name that should never be found in the temp dir/)
-----------------
To transfer the environment to the next step you can do the following:
----------------------------
$MT_MEGATEST -env2file .ezsteps/${stepname}
----------------------------
Triggers
~~~~~~~~
In your testconfig triggers can be specified
-----------------
[triggers]
# Call script running.sh when test goes to state=RUNNING, status=PASS
RUNNING/PASS running.sh
# Call script running.sh any time state goes to RUNNING
RUNNING/ running.sh
# Call script onpass.sh any time status goes to PASS
PASS/ onpass.sh
-----------------
Scripts called will have; test-id test-rundir trigger, added to the commandline.
HINT
To start an xterm (useful for debugging), use a command line like the following:
-----------------
[triggers]
COMPLETED/ xterm -e bash -s --
-----------------
NOTE: There is a trailing space after the --
Override the Toplevel HTML File
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Megatest generates a simple html file summary for top level tests of
iterated tests. The generation can be overridden. NOTE: the output of
the script is captured from stdout to create the html.
.For test "runfirst" override the toplevel generation with a script "mysummary.sh"
-----------------
# Override the rollup for specific tests
[testrollup]
runfirst mysummary.sh
-----------------
Archiving Setup
---------------
In megatest.config add the following sections:
.megatest.config
--------------
[archive]
# where to get bup executable
# bup /path/to/bup
[archive-disks]
# Archives will be organised under these paths like this:
# <testsuite>/<creationdate>
# Within the archive the data is structured like this:
# <target>/<runname>/<test>/
archive0 /mfs/myarchive-data/adisk1
--------------
Programming API
---------------
These routines can be called from the megatest repl.
