Description
|
|
===========
|
|
|
|
The :program:`ctest` executable is the CMake test driver program.
|
|
CMake-generated build trees created for projects that use the
|
|
:command:`enable_testing` and :command:`add_test` commands have testing support.
|
|
This program will run the tests and report results.
|
|
|
|
.. _`Run Tests`:
|
|
|
|
Run Tests
|
|
=========
|
|
|
|
.. program:: ctest
|
|
|
|
.. option:: --preset <preset>, --preset=<preset>
|
|
|
|
Use a test preset to specify test options. The project binary directory
|
|
is inferred from the ``configurePreset`` key. The current working directory
|
|
must contain CMake preset files.
|
|
See :manual:`preset <cmake-presets(7)>` for more details.
|
|
|
|
.. option:: --list-presets
|
|
|
|
Lists the available test presets. The current working directory must contain
|
|
CMake preset files.
|
|
|
|
.. option:: -C <cfg>, --build-config <cfg>
|
|
|
|
Choose configuration to test.
|
|
|
|
Some CMake-generated build trees can have multiple build
|
|
configurations in the same tree. This option can be used to specify
|
|
which one should be tested. Example configurations are ``Debug`` and
|
|
``Release``.
|
|
|
|
.. option:: --progress
|
|
|
|
Enable short progress output from tests.
|
|
|
|
When the output of :program:`ctest` is being sent directly to a terminal, the
|
|
progress through the set of tests is reported by updating the same line
|
|
rather than printing start and end messages for each test on new lines.
|
|
This can significantly reduce the verbosity of the test output.
|
|
Test completion messages are still output on their own line for failed
|
|
tests and the final test summary will also still be logged.
|
|
|
|
This option can also be enabled by setting the environment variable
|
|
:envvar:`CTEST_PROGRESS_OUTPUT`.
|
|
|
|
.. option:: -V, --verbose
|
|
|
|
Enable verbose output from tests.
|
|
|
|
Test output is normally suppressed and only summary information is
|
|
displayed. This option will show all test output.
|
|
|
|
.. option:: -VV, --extra-verbose
|
|
|
|
Enable more verbose output from tests.
|
|
|
|
Test output is normally suppressed and only summary information is
|
|
displayed. This option will show even more test output.
|
|
|
|
.. option:: --debug
|
|
|
|
Displaying more verbose internals of CTest.
|
|
|
|
This feature will result in a large number of output that is mostly
|
|
useful for debugging dashboard problems.
|
|
|
|
.. option:: --output-on-failure
|
|
|
|
Output anything outputted by the test program if the test should fail.
|
|
This option can also be enabled by setting the
|
|
:envvar:`CTEST_OUTPUT_ON_FAILURE` environment variable
|
|
|
|
.. option:: --stop-on-failure
|
|
|
|
Stop running the tests when the first failure happens.
|
|
|
|
.. option:: -F
|
|
|
|
Enable failover.
|
|
|
|
This option allows CTest to resume a test set execution that was
|
|
previously interrupted. If no interruption occurred, the ``-F`` option
|
|
will have no effect.
|
|
|
|
.. option:: -j [<level>], --parallel [<level>]
|
|
|
|
Run tests in parallel, optionally limited to a given level of parallelism.
|
|
|
|
.. versionadded:: 3.29
|
|
|
|
The ``<level>`` may be omitted, or ``0``, in which case:
|
|
|
|
* Under `Job Server Integration`_, parallelism is limited by
|
|
available job tokens.
|
|
|
|
* Otherwise, if the value is omitted, parallelism is limited
|
|
by the number of processors, or 2, whichever is larger.
|
|
|
|
* Otherwise, if the value is ``0``, parallelism is unbounded.
|
|
|
|
This option may instead be specified by the :envvar:`CTEST_PARALLEL_LEVEL`
|
|
environment variable.
|
|
|
|
This option can be used with the :prop_test:`PROCESSORS` test property.
|
|
See the `Label and Subproject Summary`_.
|
|
|
|
.. option:: --resource-spec-file <file>
|
|
|
|
Run CTest with :ref:`resource allocation <ctest-resource-allocation>` enabled,
|
|
using the
|
|
:ref:`resource specification file <ctest-resource-specification-file>`
|
|
specified in ``<file>``.
|
|
|
|
When :program:`ctest` is run as a `Dashboard Client`_ this sets the
|
|
``ResourceSpecFile`` option of the `CTest Test Step`_.
|
|
|
|
.. option:: --test-load <level>
|
|
|
|
While running tests in parallel (e.g. with :option:`-j <ctest -j>`), try
|
|
not to start tests when they may cause the CPU load to pass above a given
|
|
threshold.
|
|
|
|
When :program:`ctest` is run as a `Dashboard Client`_ this sets the
|
|
``TestLoad`` option of the `CTest Test Step`_.
|
|
|
|
.. option:: -Q, --quiet
|
|
|
|
Make CTest quiet.
|
|
|
|
This option will suppress all the output. The output log file will
|
|
still be generated if the :option:`--output-log <ctest --output-log>` is
|
|
specified. Options such as :option:`--verbose <ctest --verbose>`,
|
|
:option:`--extra-verbose <ctest --extra-verbose>`, and
|
|
:option:`--debug <ctest --debug>` are ignored
|
|
if ``--quiet`` is specified.
|
|
|
|
.. option:: -O <file>, --output-log <file>
|
|
|
|
Output to log file.
|
|
|
|
This option tells CTest to write all its output to a ``<file>`` log file.
|
|
|
|
.. option:: --output-junit <file>
|
|
|
|
.. versionadded:: 3.21
|
|
|
|
Write test results in JUnit format.
|
|
|
|
This option tells CTest to write test results to ``<file>`` in JUnit XML
|
|
format. If ``<file>`` already exists, it will be overwritten. If using the
|
|
:option:`-S <ctest -S>` option to run a dashboard script, use the
|
|
``OUTPUT_JUNIT`` keyword with the :command:`ctest_test` command instead.
|
|
|
|
.. option:: -N, --show-only[=<format>]
|
|
|
|
Disable actual execution of tests.
|
|
|
|
This option tells CTest to list the tests that would be run but not
|
|
actually run them. Useful in conjunction with the :option:`-R <ctest -R>`
|
|
and :option:`-E <ctest -E>` options.
|
|
|
|
.. versionadded:: 3.14
|
|
|
|
The ``--show-only`` option accepts a ``<format>`` value.
|
|
|
|
``<format>`` can be one of the following values.
|
|
|
|
``human``
|
|
Human-friendly output. This is not guaranteed to be stable.
|
|
This is the default.
|
|
|
|
``json-v1``
|
|
Dump the test information in JSON format.
|
|
See `Show as JSON Object Model`_.
|
|
|
|
.. option:: -L <regex>, --label-regex <regex>
|
|
|
|
Run tests with labels matching regular expression as described under
|
|
:ref:`string(REGEX) <Regex Specification>`.
|
|
|
|
This option tells CTest to run only the tests whose labels match the
|
|
given regular expression. When more than one ``-L`` option is given,
|
|
a test will only be run if each regular expression matches at least one
|
|
of the test's labels (i.e. the multiple ``-L`` labels form an ``AND``
|
|
relationship). See `Label Matching`_.
|
|
|
|
.. option:: -R <regex>, --tests-regex <regex>
|
|
|
|
Run tests matching regular expression.
|
|
|
|
This option tells CTest to run only the tests whose names match the
|
|
given regular expression.
|
|
|
|
.. option:: -E <regex>, --exclude-regex <regex>
|
|
|
|
Exclude tests matching regular expression.
|
|
|
|
This option tells CTest to NOT run the tests whose names match the
|
|
given regular expression.
|
|
|
|
.. option:: -LE <regex>, --label-exclude <regex>
|
|
|
|
Exclude tests with labels matching regular expression.
|
|
|
|
This option tells CTest to NOT run the tests whose labels match the
|
|
given regular expression. When more than one ``-LE`` option is given,
|
|
a test will only be excluded if each regular expression matches at least one
|
|
of the test's labels (i.e. the multiple ``-LE`` labels form an ``AND``
|
|
relationship). See `Label Matching`_.
|
|
|
|
.. option:: --tests-from-file <filename>
|
|
|
|
.. versionadded:: 3.29
|
|
|
|
Run tests listed in the given file.
|
|
|
|
This option tells CTest to run tests that are listed in the given file.
|
|
The file must contain one exact test name per line.
|
|
Lines that do not exactly match any test names are ignored.
|
|
This option can be combined with the other options like
|
|
``-R``, ``-E``, ``-L`` or ``-LE``.
|
|
|
|
.. option:: --exclude-from-file <filename>
|
|
|
|
.. versionadded:: 3.29
|
|
|
|
Exclude tests listed in the given file.
|
|
|
|
This option tells CTest to NOT run tests that are listed in the given file.
|
|
The file must contain one exact test name per line.
|
|
Lines that do not exactly match any test names are ignored.
|
|
This option can be combined with the other options like
|
|
``-R``, ``-E``, ``-L`` or ``-LE``.
|
|
|
|
.. option:: -FA <regex>, --fixture-exclude-any <regex>
|
|
|
|
Exclude fixtures matching ``<regex>`` from automatically adding any tests to
|
|
the test set.
|
|
|
|
If a test in the set of tests to be executed requires a particular fixture,
|
|
that fixture's setup and cleanup tests would normally be added to the test set
|
|
automatically. This option prevents adding setup or cleanup tests for fixtures
|
|
matching the ``<regex>``. Note that all other fixture behavior is retained,
|
|
including test dependencies and skipping tests that have fixture setup tests
|
|
that fail.
|
|
|
|
.. option:: -FS <regex>, --fixture-exclude-setup <regex>
|
|
|
|
Same as :option:`-FA <ctest -FA>` except only matching setup tests are
|
|
excluded.
|
|
|
|
.. option:: -FC <regex>, --fixture-exclude-cleanup <regex>
|
|
|
|
Same as :option:`-FA <ctest -FA>` except only matching cleanup tests are
|
|
excluded.
|
|
|
|
.. option:: -I [Start,End,Stride,test#,test#|Test file], --tests-information
|
|
|
|
Run a specific number of tests by number.
|
|
|
|
This option causes CTest to run tests starting at number ``Start``,
|
|
ending at number ``End``, and incrementing by ``Stride``. Any additional
|
|
numbers after ``Stride`` are considered individual test numbers. ``Start``,
|
|
``End``, or ``Stride`` can be empty. Optionally a file can be given that
|
|
contains the same syntax as the command line.
|
|
|
|
.. option:: -U, --union
|
|
|
|
Take the Union of :option:`-I <ctest -I>` and :option:`-R <ctest -R>`.
|
|
|
|
When both :option:`-R <ctest -R>` and :option:`-I <ctest -I>` are specified
|
|
by default the intersection of tests are run. By specifying ``-U`` the union
|
|
of tests is run instead.
|
|
|
|
.. option:: --rerun-failed
|
|
|
|
Run only the tests that failed previously.
|
|
|
|
This option tells CTest to perform only the tests that failed during
|
|
its previous run. When this option is specified, CTest ignores all
|
|
other options intended to modify the list of tests to run (
|
|
:option:`-L <ctest -L>`, :option:`-R <ctest -R>`, :option:`-E <ctest -E>`,
|
|
:option:`-LE <ctest -LE>`, :option:`-I <ctest -I>`, etc). In the event that
|
|
CTest runs and no tests fail, subsequent calls to CTest with the
|
|
``--rerun-failed`` option will run the set of tests that most recently
|
|
failed (if any).
|
|
|
|
.. option:: --repeat <mode>:<n>
|
|
|
|
Run tests repeatedly based on the given ``<mode>`` up to ``<n>`` times.
|
|
The modes are:
|
|
|
|
``until-fail``
|
|
Require each test to run ``<n>`` times without failing in order to pass.
|
|
This is useful in finding sporadic failures in test cases.
|
|
|
|
``until-pass``
|
|
Allow each test to run up to ``<n>`` times in order to pass.
|
|
Repeats tests if they fail for any reason.
|
|
This is useful in tolerating sporadic failures in test cases.
|
|
|
|
``after-timeout``
|
|
Allow each test to run up to ``<n>`` times in order to pass.
|
|
Repeats tests only if they timeout.
|
|
This is useful in tolerating sporadic timeouts in test cases
|
|
on busy machines.
|
|
|
|
.. option:: --repeat-until-fail <n>
|
|
|
|
Equivalent to :option:`--repeat until-fail:\<n\> <ctest --repeat>`.
|
|
|
|
.. option:: --max-width <width>
|
|
|
|
Set the max width for a test name to output.
|
|
|
|
Set the maximum width for each test name to show in the output.
|
|
This allows the user to widen the output to avoid clipping the test
|
|
name which can be very annoying.
|
|
|
|
.. option:: --interactive-debug-mode [0|1]
|
|
|
|
Set the interactive mode to ``0`` or ``1``.
|
|
|
|
This option causes CTest to run tests in either an interactive mode
|
|
or a non-interactive mode. In dashboard mode (``Experimental``, ``Nightly``,
|
|
``Continuous``), the default is non-interactive. In non-interactive mode,
|
|
the environment variable :envvar:`DASHBOARD_TEST_FROM_CTEST` is set.
|
|
|
|
Prior to CMake 3.11, interactive mode on Windows allowed system debug
|
|
popup windows to appear. Now, due to CTest's use of ``libuv`` to launch
|
|
test processes, all system debug popup windows are always blocked.
|
|
|
|
.. option:: --no-label-summary
|
|
|
|
Disable timing summary information for labels.
|
|
|
|
This option tells CTest not to print summary information for each
|
|
label associated with the tests run. If there are no labels on the
|
|
tests, nothing extra is printed.
|
|
|
|
See `Label and Subproject Summary`_.
|
|
|
|
.. option:: --no-subproject-summary
|
|
|
|
Disable timing summary information for subprojects.
|
|
|
|
This option tells CTest not to print summary information for each
|
|
subproject associated with the tests run. If there are no subprojects on the
|
|
tests, nothing extra is printed.
|
|
|
|
See `Label and Subproject Summary`_.
|
|
|
|
.. option:: --test-dir <dir>
|
|
|
|
.. versionadded:: 3.20
|
|
|
|
Specify the directory in which to look for tests, typically a CMake project
|
|
build directory. If not specified, the current directory is used.
|
|
|
|
.. option:: --test-output-size-passed <size>
|
|
|
|
.. versionadded:: 3.4
|
|
|
|
Limit the output for passed tests to ``<size>`` bytes.
|
|
|
|
.. option:: --test-output-size-failed <size>
|
|
|
|
.. versionadded:: 3.4
|
|
|
|
Limit the output for failed tests to ``<size>`` bytes.
|
|
|
|
.. option:: --test-output-truncation <mode>
|
|
|
|
.. versionadded:: 3.24
|
|
|
|
Truncate ``tail`` (default), ``middle`` or ``head`` of test output once
|
|
maximum output size is reached.
|
|
|
|
.. option:: --overwrite
|
|
|
|
Overwrite CTest configuration option.
|
|
|
|
By default CTest uses configuration options from configuration file.
|
|
This option will overwrite the configuration option.
|
|
|
|
.. option:: --force-new-ctest-process
|
|
|
|
Run child CTest instances as new processes.
|
|
|
|
By default CTest will run child CTest instances within the same
|
|
process. If this behavior is not desired, this argument will
|
|
enforce new processes for child CTest processes.
|
|
|
|
.. option:: --schedule-random
|
|
|
|
Use a random order for scheduling tests.
|
|
|
|
This option will run the tests in a random order. It is commonly
|
|
used to detect implicit dependencies in a test suite.
|
|
|
|
.. option:: --submit-index
|
|
|
|
Legacy option for old Dart2 dashboard server feature.
|
|
Do not use.
|
|
|
|
.. option:: --timeout <seconds>
|
|
|
|
Set the default test timeout.
|
|
|
|
This option effectively sets a timeout on all tests that do not
|
|
already have a timeout set on them via the :prop_test:`TIMEOUT`
|
|
property.
|
|
|
|
.. option:: --stop-time <time>
|
|
|
|
Set a time at which all tests should stop running.
|
|
|
|
Set a real time of day at which all tests should timeout. Example:
|
|
``7:00:00 -0400``. Any time format understood by the curl date parser
|
|
is accepted. Local time is assumed if no timezone is specified.
|
|
|
|
.. option:: --print-labels
|
|
|
|
Print all available test labels.
|
|
|
|
This option will not run any tests, it will simply print the list of
|
|
all labels associated with the test set.
|
|
|
|
.. option:: --no-tests=<action>
|
|
|
|
Regard no tests found either as error (when ``<action>`` is set to
|
|
``error``) or ignore it (when ``<action>`` is set to ``ignore``).
|
|
|
|
If no tests were found, the default behavior of CTest is to always log an
|
|
error message but to return an error code in script mode only. This option
|
|
unifies the behavior of CTest by either returning an error code if no tests
|
|
were found or by ignoring it.
|
|
|
|
.. versionadded:: 3.26
|
|
|
|
This option can also be set by setting the :envvar:`CTEST_NO_TESTS_ACTION`
|
|
environment variable.

.. _`Label Matching`:
|
|
|
|
Label Matching
|
|
==============
|
|
|
|
Tests may have labels attached to them. Tests may be included
|
|
or excluded from a test run by filtering on the labels.
|
|
Each individual filter is a regular expression applied to
|
|
the labels attached to a test.
|
|
|
|
When :option:`-L <ctest -L>` is used, in order for a test to be included in a
|
|
test run, each regular expression must match at least one
|
|
label. Using more than one :option:`-L <ctest -L>` option means "match **all**
|
|
of these".
|
|
|
|
The :option:`-LE <ctest -LE>` option works just like :option:`-L <ctest -L>`,
|
|
but excludes tests rather than including them. A test is excluded if each
|
|
regular expression matches at least one label.
|
|
|
|
If a test has no labels attached to it, then :option:`-L <ctest -L>` will never
|
|
include that test, and :option:`-LE <ctest -LE>` will never exclude that test.
|
|
As an example of tests with labels, consider five tests,
|
|
with the following labels:
|
|
|
|
* *test1* has labels *tuesday* and *production*
|
|
* *test2* has labels *tuesday* and *test*
|
|
* *test3* has labels *wednesday* and *production*
|
|
* *test4* has label *wednesday*
|
|
* *test5* has labels *friday* and *test*
|
|
|
|
Running :program:`ctest` with ``-L tuesday -L test`` will select *test2*, which has
|
|
both labels. Running CTest with ``-L test`` will select *test2* and
|
|
*test5*, because both of them have a label that matches that regular
|
|
expression.
|
|
|
|
Because the matching works with regular expressions, take note that
|
|
running CTest with ``-L es`` will match all five tests.
|
|
To select the *tuesday* and *wednesday* tests together, use a single
|
|
regular expression that matches either of them, like ``-L "tue|wed"``.
|
|
|
|
.. _`Label and Subproject Summary`:
|
|
|
|
Label and Subproject Summary
|
|
============================
|
|
|
|
CTest prints timing summary information for each ``LABEL`` and subproject
|
|
associated with the tests run. The label time summary will not include labels
|
|
that are mapped to subprojects.
|
|
|
|
.. versionadded:: 3.22
|
|
Labels added dynamically during test execution are also reported in the
|
|
timing summary. See :ref:`Additional Labels`.
|
|
|
|
When the :prop_test:`PROCESSORS` test property is set, CTest will display a
|
|
weighted test timing result in label and subproject summaries. The time is
|
|
reported with `sec*proc` instead of just `sec`.
|
|
|
|
The weighted time summary reported for each label or subproject ``j``
|
|
is computed as::
|
|
|
|
Weighted Time Summary for Label/Subproject j =
|
|
sum(raw_test_time[j,i] * num_processors[j,i], i=1...num_tests[j])
|
|
|
|
for labels/subprojects j=1...total
|
|
|
|
where:
|
|
|
|
* ``raw_test_time[j,i]``: Wall-clock time for the ``i`` test
|
|
for the ``j`` label or subproject
|
|
* ``num_processors[j,i]``: Value of the CTest :prop_test:`PROCESSORS` property
|
|
for the ``i`` test for the ``j`` label or subproject
|
|
* ``num_tests[j]``: Number of tests associated with the ``j`` label or subproject
|
|
* ``total``: Total number of labels or subprojects that have at least one test run
|
|
|
|
Therefore, the weighted time summary for each label or subproject represents
|
|
the amount of time that CTest gave to run the tests for each label or
|
|
subproject and gives a good representation of the total expense of the tests
|
|
for each label or subproject when compared to other labels or subprojects.
|
|
|
|
For example, if ``SubprojectA`` showed ``100 sec*proc`` and ``SubprojectB`` showed
|
|
``10 sec*proc``, then CTest allocated approximately 10 times the CPU/core time
|
|
to run the tests for ``SubprojectA`` than for ``SubprojectB`` (e.g. so if effort
|
|
is going to be expended to reduce the cost of the test suite for the whole
|
|
project, then reducing the cost of the test suite for ``SubprojectA`` would
|
|
likely have a larger impact than effort to reduce the cost of the test suite
|
|
for ``SubprojectB``).

|
|
.. _`Build and Test Mode`:
|
|
|
|
Build and Test Mode
|
|
===================
|
|
|
|
CTest provides a command-line signature to configure (i.e. run cmake on),
|
|
build, and/or execute a test::
|
|
|
|
ctest --build-and-test <path-to-source> <path-to-build>
|
|
--build-generator <generator>
|
|
[<options>...]
|
|
[--build-options <opts>...]
|
|
[--test-command <command> [<args>...]]
|
|
|
|
The configure and test steps are optional. The arguments to this command line
|
|
are the source and binary directories. The ``--build-generator`` option *must*
|
|
be provided to use ``--build-and-test``. If ``--test-command`` is specified
|
|
then that will be run after the build is complete. Other options that affect
|
|
this mode include:
|
|
|
|
.. option:: --build-and-test
|
|
|
|
Switch into the build and test mode.
|
|
|
|
.. option:: --build-target
|
|
|
|
Specify a specific target to build. The option can be given multiple times
|
|
with different targets, in which case each target is built in turn.
|
|
A clean will be done before building each target unless the
|
|
:option:`--build-noclean` option is given.
|
|
|
|
If no ``--build-target`` is specified, the ``all`` target is built.
|
|
|
|
.. option:: --build-nocmake
|
|
|
|
Run the build without running cmake first.
|
|
|
|
Skip the cmake step.
|
|
|
|
.. option:: --build-run-dir
|
|
|
|
Specify directory to run programs from.
|
|
|
|
Directory where programs will be after it has been compiled.
|
|
|
|
.. option:: --build-two-config
|
|
|
|
Run CMake twice.
|
|
|
|
.. option:: --build-exe-dir
|
|
|
|
Specify the directory for the executable.
|
|
|
|
.. option:: --build-generator
|
|
|
|
Specify the generator to use. See the :manual:`cmake-generators(7)` manual.
|
|
|
|
.. option:: --build-generator-platform
|
|
|
|
Specify the generator-specific platform.
|
|
|
|
.. option:: --build-generator-toolset
|
|
|
|
Specify the generator-specific toolset.
|
|
|
|
.. option:: --build-project
|
|
|
|
Specify the name of the project to build.
|
|
|
|
.. option:: --build-makeprogram
|
|
|
|
Specify the explicit make program to be used by CMake when configuring and
|
|
building the project. Only applicable for Make and Ninja based generators.
|
|
|
|
.. option:: --build-noclean
|
|
|
|
Skip the make clean step.
|
|
|
|
.. option:: --build-config-sample
|
|
|
|
A sample executable to use to determine the configuration that
|
|
should be used. e.g. ``Debug``, ``Release`` etc.
|
|
|
|
.. option:: --build-options
|
|
|
|
Additional options for configuring the build (i.e. for CMake, not for
|
|
the build tool). Note that if this is specified, the ``--build-options``
|
|
keyword and its arguments must be the last option given on the command
|
|
line, with the possible exception of ``--test-command``.
|
|
|
|
.. option:: --test-command
|
|
|
|
The command to run as the test step with the
|
|
:option:`--build-and-test <ctest --build-and-test>` option.
|
|
All arguments following this keyword will be assumed to be part of the
|
|
test command line, so it must be the last option given.
|
|
|
|
.. option:: --test-timeout
|
|
|
|
The time limit in seconds
|
|
|
|
.. _`Dashboard Client`:
|
|
|
|
Dashboard Client
|
|
================
|
|
|
|
CTest can operate as a client for the `CDash`_ software quality dashboard
|
|
application. As a dashboard client, CTest performs a sequence of steps
|
|
to configure, build, and test software, and then submits the results to
|
|
a `CDash`_ server. The command-line signature used to submit to `CDash`_ is::
|
|
|
|
ctest -D <dashboard> [-- <dashboard-options>...]
|
|
ctest -M <model> -T <action> [-- <dashboard-options>...]
|
|
ctest -S <script> [-- <dashboard-options>...]
|
|
ctest -SP <script> [-- <dashboard-options>...]
|
|
|
|
.. _`CDash`: https://www.cdash.org
|
|
|
|
Options for Dashboard Client include:
|
|
|
|
.. option:: -D <dashboard>, --dashboard <dashboard>
|
|
|
|
Execute dashboard test.
|
|
|
|
This option tells CTest to act as a CDash client and perform a
|
|
dashboard test. All tests are ``<Mode><Test>``, where ``<Mode>`` can be
|
|
``Experimental``, ``Nightly``, and ``Continuous``, and ``<Test>`` can be
|
|
``Start``, ``Update``, ``Configure``, ``Build``, ``Test``,
|
|
``Coverage``, and ``Submit``.
|
|
|
|
If ``<dashboard>`` is not one of the recognized ``<Mode><Test>`` values,
|
|
this will be treated as a variable definition instead (see the
|
|
:ref:`dashboard-options <Dashboard Options>` further below).
|
|
|
|
.. option:: -M <model>, --test-model <model>
|
|
|
|
Sets the model for a dashboard.
|
|
|
|
This option tells CTest to act as a CDash client where the ``<model>``
|
|
can be ``Experimental``, ``Nightly``, and ``Continuous``.
|
|
Combining ``-M`` and :option:`-T <ctest -T>` is similar to
|
|
:option:`-D <ctest -D>`.
|
|
|
|
.. option:: -T <action>, --test-action <action>
|
|
|
|
Sets the dashboard action to perform.
|
|
|
|
This option tells CTest to act as a CDash client and perform some
|
|
action such as ``start``, ``build``, ``test`` etc. See
|
|
`Dashboard Client Steps`_ for the full list of actions.
|
|
Combining :option:`-M <ctest -M>` and ``-T`` is similar to
|
|
:option:`-D <ctest -D>`.
|
|
|
|
.. option:: -S <script>, --script <script>
|
|
|
|
Execute a dashboard for a configuration.
|
|
|
|
This option tells CTest to load in a configuration script which sets
|
|
a number of parameters such as the binary and source directories.
|
|
Then CTest will do what is required to create and run a dashboard.
|
|
This option basically sets up a dashboard and then runs :option:`ctest -D`
|
|
with the appropriate options.
|
|
|
|
.. option:: -SP <script>, --script-new-process <script>
|
|
|
|
Execute a dashboard for a configuration.
|
|
|
|
This option does the same operations as :option:`-S <ctest -S>` but it
|
|
will do them in a separate process. This is primarily useful in cases
|
|
where the script may modify the environment and you do not want the modified
|
|
environment to impact other :option:`-S <ctest -S>` scripts.
|
|
|
|
.. _`Dashboard Options`:
|
|
|
|
The available ``<dashboard-options>`` are the following:
|
|
|
|
.. option:: -D <var>:<type>=<value>
|
|
|
|
Define a variable for script mode.
|
|
|
|
Pass in variable values on the command line. Use in conjunction
|
|
with :option:`-S <ctest -S>` to pass variable values to a dashboard script.
|
|
Parsing ``-D`` arguments as variable values is only attempted if the value
|
|
following ``-D`` does not match any of the known dashboard types.
|
|
|
|
.. option:: --group <group>
|
|
|
|
Specify what group you'd like to submit results to
|
|
|
|
Submit dashboard to specified group instead of default one. By
|
|
default, the dashboard is submitted to Nightly, Experimental, or
|
|
Continuous group, but by specifying this option, the group can be
|
|
arbitrary.
|
|
|
|
This replaces the deprecated option ``--track``.
|
|
Despite the name change its behavior is unchanged.
|
|
|
|
.. option:: -A <file>, --add-notes <file>
|
|
|
|
Add a notes file with submission.
|
|
|
|
This option tells CTest to include a notes file when submitting
|
|
dashboard.
|
|
|
|
.. option:: --tomorrow-tag
|
|
|
|
``Nightly`` or ``Experimental`` starts with next day tag.
|
|
|
|
This is useful if the build will not finish in one day.
|
|
|
|
.. option:: --extra-submit <file>[;<file>]
|
|
|
|
Submit extra files to the dashboard.
|
|
|
|
This option will submit extra files to the dashboard.
|
|
|
|
.. option:: --http-header <header>
|
|
|
|
.. versionadded:: 3.29
|
|
|
|
Append HTTP header when submitting to the dashboard.
|
|
|
|
This option will cause CTest to append the specified header
|
|
when submitting to the dashboard.
|
|
This option may be specified more than once.
|
|
|
|
.. option:: --http1.0
|
|
|
|
Submit using `HTTP 1.0`.
|
|
|
|
This option will force CTest to use `HTTP 1.0` to submit files to the
|
|
dashboard, instead of `HTTP 1.1`.
|
|
|
|
.. option:: --no-compress-output
|
|
|
|
Do not compress test output when submitting.
|
|
|
|
This flag will turn off automatic compression of test output. Use
|
|
this to maintain compatibility with an older version of CDash which
|
|
doesn't support compressed test output.
|
|
|
|
Dashboard Client Steps
|
|
----------------------
|
|
|
|
CTest defines an ordered list of testing steps of which some or all may
|
|
be run as a dashboard client:
|
|
|
|
``Start``
|
|
Start a new dashboard submission to be composed of results recorded
|
|
by the following steps.
|
|
See the `CTest Start Step`_ section below.
|
|
|
|
``Update``
|
|
Update the source tree from its version control repository.
|
|
Record the old and new versions and the list of updated source files.
|
|
See the `CTest Update Step`_ section below.
|
|
|
|
``Configure``
|
|
Configure the software by running a command in the build tree.
|
|
Record the configuration output log.
|
|
See the `CTest Configure Step`_ section below.
|
|
|
|
``Build``
|
|
Build the software by running a command in the build tree.
|
|
Record the build output log and detect warnings and errors.
|
|
See the `CTest Build Step`_ section below.
|
|
|
|
``Test``
|
|
Test the software by loading a ``CTestTestfile.cmake``
|
|
from the build tree and executing the defined tests.
|
|
Record the output and result of each test.
|
|
See the `CTest Test Step`_ section below.
|
|
|
|
``Coverage``
|
|
Compute coverage of the source code by running a coverage
|
|
analysis tool and recording its output.
|
|
See the `CTest Coverage Step`_ section below.
|
|
|
|
``MemCheck``
|
|
Run the software test suite through a memory check tool.
|
|
Record the test output, results, and issues reported by the tool.
|
|
See the `CTest MemCheck Step`_ section below.
|
|
|
|
``Submit``
|
|
Submit results recorded from other testing steps to the
|
|
software quality dashboard server.
|
|
See the `CTest Submit Step`_ section below.
|
|
|
|
Dashboard Client Modes
|
|
----------------------
|
|
|
|
CTest defines three modes of operation as a dashboard client:
|
|
|
|
``Nightly``
|
|
This mode is intended to be invoked once per day, typically at night.
|
|
It enables the ``Start``, ``Update``, ``Configure``, ``Build``, ``Test``,
|
|
``Coverage``, and ``Submit`` steps by default. Selected steps run even
|
|
if the ``Update`` step reports no changes to the source tree.
|
|
|
|
``Continuous``
|
|
This mode is intended to be invoked repeatedly throughout the day.
|
|
It enables the ``Start``, ``Update``, ``Configure``, ``Build``, ``Test``,
|
|
``Coverage``, and ``Submit`` steps by default, but exits after the
|
|
``Update`` step if it reports no changes to the source tree.
|
|
|
|
``Experimental``
|
|
This mode is intended to be invoked by a developer to test local changes.
|
|
It enables the ``Start``, ``Configure``, ``Build``, ``Test``, ``Coverage``,
|
|
and ``Submit`` steps by default.
|
|
|
|
Dashboard Client via CTest Command-Line
|
|
---------------------------------------
|
|
|
|
CTest can perform testing on an already-generated build tree.
|
|
Run the :program:`ctest` command with the current working directory set
|
|
to the build tree and use one of these signatures::
|
|
|
|
ctest -D <mode>[<step>]
|
|
ctest -M <mode> [-T <step>]...
|
|
|
|
The ``<mode>`` must be one of the above `Dashboard Client Modes`_,
|
|
and each ``<step>`` must be one of the above `Dashboard Client Steps`_.
|
|
|
|
CTest reads the `Dashboard Client Configuration`_ settings from
|
|
a file in the build tree called either ``CTestConfiguration.ini``
|
|
or ``DartConfiguration.tcl`` (the names are historical). The format
|
|
of the file is::
|
|
|
|
# Lines starting in '#' are comments.
|
|
# Other non-blank lines are key-value pairs.
|
|
<setting>: <value>
|
|
|
|
where ``<setting>`` is the setting name and ``<value>`` is the
|
|
setting value.
|
|
|
|
In build trees generated by CMake, this configuration file is
|
|
generated by the :module:`CTest` module if included by the project.
|
|
The module uses variables to obtain a value for each setting
|
|
as documented with the settings below.
|
|
|
|
.. _`CTest Script`:
|
|
|
|
Dashboard Client via CTest Script
|
|
---------------------------------
|
|
|
|
CTest can perform testing driven by a :manual:`cmake-language(7)`
|
|
script that creates and maintains the source and build tree as
|
|
well as performing the testing steps. Run the :program:`ctest` command
|
|
with the current working directory set outside of any build tree
|
|
and use one of these signatures::
|
|
|
|
ctest -S <script>
|
|
ctest -SP <script>
|
|
|
|
The ``<script>`` file must call :ref:`CTest Commands` commands
|
|
to run testing steps explicitly as documented below. The commands
|
|
obtain `Dashboard Client Configuration`_ settings from their
|
|
arguments or from variables set in the script.
|
|
|
|
Dashboard Client Configuration
|
|
==============================
|
|
|
|
The `Dashboard Client Steps`_ may be configured by named
|
|
settings as documented in the following sections.
|
|
|
|
.. _`CTest Start Step`:
|
|
|
|
CTest Start Step
|
|
----------------
|
|
|
|
Start a new dashboard submission to be composed of results recorded
|
|
by the following steps.
|
|
|
|
In a `CTest Script`_, the :command:`ctest_start` command runs this step.
|
|
Arguments to the command may specify some of the step settings.
|
|
The command first runs the command-line specified by the
|
|
``CTEST_CHECKOUT_COMMAND`` variable, if set, to initialize the source
|
|
directory.
|
|
|
|
Configuration settings include:
|

|
|
|
|
``SVNUpdateOptions``
|
|
Command-line options to the ``SVNCommand`` when updating the source.
|
|
|
|
* `CTest Script`_ variable: :variable:`CTEST_SVN_UPDATE_OPTIONS`
|
|
* :module:`CTest` module variable: ``SVN_UPDATE_OPTIONS``
|
|
|
|
``UpdateCommand``
|
|
Specify the version-control command-line tool to use without
|
|
detecting the VCS that manages the source tree.
|
|
|
|
* `CTest Script`_ variable: :variable:`CTEST_UPDATE_COMMAND`
|

|
|
when ``UPDATE_TYPE`` is ``<vcs>``, else ``UPDATE_COMMAND``
|
|
|
|
``UpdateOptions``
|
|
Command-line options to the ``UpdateCommand``.
|
|
|
|
* `CTest Script`_ variable: :variable:`CTEST_UPDATE_OPTIONS`
|
|
* :module:`CTest` module variable: ``<VCS>_UPDATE_OPTIONS``
|
|
when ``UPDATE_TYPE`` is ``<vcs>``, else ``UPDATE_OPTIONS``
|
|
|
|
``UpdateType``
|
|
Specify the version-control system that manages the source
|
|
tree if it cannot be detected automatically.
|
|
The value may be ``bzr``, ``cvs``, ``git``, ``hg``,
|
|
``p4``, or ``svn``.
|
|
|
|
* `CTest Script`_ variable: none, detected from source tree
|
|
* :module:`CTest` module variable: ``UPDATE_TYPE`` if set,

|
|
|
.. _`UpdateVersionOnly`:
|
|
|
|
``UpdateVersionOnly``
|
|
Specify that you want the version control update command to only

discover the current version that is checked out, and not to update
|
|
to a different version.

|
|
|
|
.. _`UpdateVersionOverride`:
|
|
|
|
``UpdateVersionOverride``
|
|
Specify the current version of your source tree.
|
|
|
|
When this variable is set to a non-empty string, CTest will report the value
|
|
you specified rather than using the update command to discover the current
|
|
version that is checked out. Use of this variable supersedes
|
|
``UpdateVersionOnly``. Like ``UpdateVersionOnly``, using this variable tells
|
|
CTest not to update the source tree to a different version.
|
|
|
|
* `CTest Script`_ variable: :variable:`CTEST_UPDATE_VERSION_OVERRIDE`
|
|
|
|
Additional configuration settings include:
|
|
|
|
``NightlyStartTime``
|
|
In the ``Nightly`` dashboard mode, specify the "nightly start time".
|
|
With centralized version control systems (``cvs`` and ``svn``),
|
|
the ``Update`` step checks out the version of the software as of
|
|
this time so that multiple clients choose a common version to test.
|
|
This is not well-defined in distributed version-control systems so
|
|
the setting is ignored.
|
|
|
|
* `CTest Script`_ variable: :variable:`CTEST_NIGHTLY_START_TIME`
|
|
* :module:`CTest` module variable: ``NIGHTLY_START_TIME`` if set,

|
|
of the configuration (e.g. ``Debug``, ``Release``), this specifies
|
|
the default configuration to be built when no :option:`-C <ctest -C>`
|
|
option is given to the :program:`ctest` command. The value will be substituted
|
|
into the value of ``MakeCommand`` to replace the literal string
|
|
``${CTEST_CONFIGURATION_TYPE}`` if it appears.
|
|
|
|
* `CTest Script`_ variable: :variable:`CTEST_CONFIGURATION_TYPE`

generator, specify whether the
|
|
``CTEST_USE_LAUNCHERS`` feature is enabled by the
|
|
:module:`CTestUseLaunchers` module (also included by the
|
|
:module:`CTest` module). When enabled, the generated build
|
|
system wraps each invocation of the compiler, linker, or
|
|
custom command line with a "launcher" that communicates
|
|
with CTest via environment variables and files to report
|
|
granular build warning and error information. Otherwise,
|
|
CTest must "scrape" the build output log for diagnostics.

Resource Allocation
|
|
===================
|
|
|
|
CTest provides a mechanism for tests to specify the resources that they need
|
|
in a fine-grained way, and for users to specify the resources available on
|
|
the running machine. This allows CTest to internally keep track of which
|
|
resources are in use and which are free, scheduling tests in a way that
|
|
prevents them from trying to claim resources that are not available.
|
|
|
|
When the resource allocation feature is used, CTest will not oversubscribe
|
|
resources. For example, if a resource has 8 slots, CTest will not run tests
|
|
that collectively use more than 8 slots at a time. This has the effect of
|
|
limiting how many tests can run at any given time, even if a high ``-j``
|
|
argument is used, if those tests all use some slots from the same resource.
|
|
In addition, it means that a single test that uses more of a resource than is
|
|
available on a machine will not run at all (and will be reported as
|
|
``Not Run``).
|
|
|
|
A common use case for this feature is for tests that require the use of a GPU.
|
|
Multiple tests can simultaneously allocate memory from a GPU, but if too many
|
|
tests try to do this at once, some of them will fail to allocate, resulting in
|
|
a failed test, even though the test would have succeeded if it had the memory
|
|
it needed. By using the resource allocation feature, each test can specify how
|
|
much memory it requires from a GPU, allowing CTest to schedule tests in a way
|
|
that running several of these tests at once does not exhaust the GPU's memory
|
|
pool.
|
|
|
|
Please note that CTest has no concept of what a GPU is or how much memory it
|
|
has. It does not have any way of communicating with a GPU to retrieve this
|
|
information or perform any memory management, although the project can define
|
|
a test that provides details about the test machine (see
|
|
:ref:`ctest-resource-dynamically-generated-spec-file`).
|
|
|
|
CTest keeps track of a list of abstract resource types, each of which has a
|
|
certain number of slots available for tests to use. Each test specifies the
|
|
number of slots that it requires from a certain resource, and CTest then
|
|
schedules them in a way that prevents the total number of slots in use from
|
|
exceeding the listed capacity. When a test is executed, and slots from a
|
|
resource are allocated to that test, tests may assume that they have exclusive
|
|
use of those slots for the duration of the test's process.
|
|
|
|
The CTest resource allocation feature consists of at least two inputs:
|
|
|
|
* The :ref:`resource specification file <ctest-resource-specification-file>`,
|
|
described below, which describes the resources available on the system.
|
|
* The :prop_test:`RESOURCE_GROUPS` property of tests, which describes the
|
|
resources required by the test.
|
|
|
|
When CTest runs a test, the resources allocated to that test are passed in the
|
|
form of a set of
|
|
:ref:`environment variables <ctest-resource-environment-variables>` as
|
|
described below. Using this information to decide which resource to connect to
|
|
is left to the test writer.
|
|
|
|
The ``RESOURCE_GROUPS`` property tells CTest what resources a test expects
|
|
to use grouped in a way meaningful to the test. The test itself must read
|
|
the :ref:`environment variables <ctest-resource-environment-variables>` to
|
|
determine which resources have been allocated to each group. For example,
|
|
each group may correspond to a process the test will spawn when executed.
|
|
|
|
Note that even if a test specifies a ``RESOURCE_GROUPS`` property, it is still
|
|
possible for that to test to run without any resource allocation (and without
|
|
the corresponding
|
|
:ref:`environment variables <ctest-resource-environment-variables>`)
|
|
if the user does not pass a resource specification file. Passing this file,
|
|
either through the ``--resource-spec-file`` command-line argument or the
|
|
``RESOURCE_SPEC_FILE`` argument to :command:`ctest_test`, is what activates the
|
|
resource allocation feature. Tests should check the
|
|
``CTEST_RESOURCE_GROUP_COUNT`` environment variable to find out whether or not
|
|
resource allocation is activated. This variable will always (and only) be
|
|
defined if resource allocation is activated. If resource allocation is not
|
|
activated, then the ``CTEST_RESOURCE_GROUP_COUNT`` variable will not exist,
|
|
even if it exists for the parent :program:`ctest` process. If a test absolutely must
|
|
have resource allocation, then it can return a failing exit code or use the
|
|
:prop_test:`SKIP_RETURN_CODE` or :prop_test:`SKIP_REGULAR_EXPRESSION`
|
|
properties to indicate a skipped test.

|
|
Resource Specification File
|
|
---------------------------
|
|
|
|
The resource specification file is a JSON file which is passed to CTest in one
|
|
of a number of ways. It can be specified on the command line with the
|
|
:option:`ctest --resource-spec-file` option, it can be given using the
|
|
``RESOURCE_SPEC_FILE`` argument of :command:`ctest_test`, or it can be
|
|
generated dynamically as part of test execution (see
|
|
:ref:`ctest-resource-dynamically-generated-spec-file`).
|
|
|
|
If a dashboard script is used and ``RESOURCE_SPEC_FILE`` is not specified, the
|
|
value of :variable:`CTEST_RESOURCE_SPEC_FILE` in the dashboard script is used
|
|
instead. If :option:`--resource-spec-file <ctest --resource-spec-file>`,
|
|
``RESOURCE_SPEC_FILE``, and :variable:`CTEST_RESOURCE_SPEC_FILE` in the
|
|
dashboard script are not specified, the value of
|
|
:variable:`CTEST_RESOURCE_SPEC_FILE` in the CMake build is used instead.
|
|
If none of these are specified, no resource spec file is used.
|
|
|
|
The resource specification file must be a JSON object. All examples in this
|
|
document assume the following resource specification file:
|
|
|
|
.. code-block:: json
|
|
|
|
{
|
|
"version": {
|
|
"major": 1,
|
|
"minor": 0
|
|
},
|
|
"local": [
|
|
{
|
|
"gpus": [
|
|
{
|
|
"id": "0",
|
|
"slots": 2
|
|
},
|
|
{
|
|
"id": "1",
|
|
"slots": 4
|
|
},
|
|
{
|
|
"id": "2",
|
|
"slots": 2
|
|
},
|
|
{
|
|
"id": "3"
|
|
}
|
|
],
|
|
"crypto_chips": [
|
|
{
|
|
"id": "card0",
|
|
"slots": 4
|
|
}
|
|
]
|
|
}
|
|
]
|
|
}
|
|
|
|
The members are:
|
|
|
|
``version``
|
|
An object containing a ``major`` integer field and a ``minor`` integer field.
|
|
Currently, the only supported version is major ``1``, minor ``0``. Any other
|
|
value is an error.
|
|
|
|
``local``
|
|
A JSON array of resource sets present on the system. Currently, this array
|
|
is restricted to being of size 1.
|
|
|
|
Each array element is a JSON object with members whose names are equal to the
|
|
desired resource types, such as ``gpus``. These names must start with a
|
|
lowercase letter or an underscore, and subsequent characters can be a
|
|
lowercase letter, a digit, or an underscore. Uppercase letters are not
|
|
allowed, because certain platforms have case-insensitive environment
|
|
variables. See the `Environment Variables`_ section below for
|
|
more information. It is recommended that the resource type name be the plural
|
|
of a noun, such as ``gpus`` or ``crypto_chips`` (and not ``gpu`` or
|
|
``crypto_chip``.)
|
|
|
|
Please note that the names ``gpus`` and ``crypto_chips`` are just examples,
|
|
and CTest does not interpret them in any way. You are free to make up any
|
|
resource type you want to meet your own requirements.
|
|
|
|
The value for each resource type is a JSON array consisting of JSON objects,
|
|
each of which describe a specific instance of the specified resource. These
|
|
objects have the following members:
|
|
|
|
``id``
|
|
A string consisting of an identifier for the resource. Each character in
|
|
the identifier can be a lowercase letter, a digit, or an underscore.
|
|
Uppercase letters are not allowed.
|
|
|
|
Identifiers must be unique within a resource type. However, they do not
|
|
have to be unique across resource types. For example, it is valid to have a
|
|
``gpus`` resource named ``0`` and a ``crypto_chips`` resource named ``0``,
|
|
but not two ``gpus`` resources both named ``0``.
|
|
|
|
Please note that the IDs ``0``, ``1``, ``2``, ``3``, and ``card0`` are just
|
|
examples, and CTest does not interpret them in any way. You are free to
|
|
make up any IDs you want to meet your own requirements.
|
|
|
|
``slots``
|
|
An optional unsigned number specifying the number of slots available on the
|
|
resource. For example, this could be megabytes of RAM on a GPU, or
|
|
cryptography units available on a cryptography chip. If ``slots`` is not
|
|
specified, a default value of ``1`` is assumed.
|
|
|
|
In the example file above, there are four GPUs with ID's 0 through 3. GPU 0 has
|
|
2 slots, GPU 1 has 4, GPU 2 has 2, and GPU 3 has a default of 1 slot. There is
|
|
also one cryptography chip with 4 slots.
|
|
|
|
``RESOURCE_GROUPS`` Property
|
|
----------------------------
|
|
|
|
See :prop_test:`RESOURCE_GROUPS` for a description of this property.
|
|
|
|
.. _`ctest-resource-environment-variables`:
|
|
|
|
Environment Variables
|
|
---------------------
|
|
|
|
Once CTest has decided which resources to allocate to a test, it passes this
|
|
information to the test executable as a series of environment variables. For
|
|
each example below, we will assume that the test in question has a
|
|
:prop_test:`RESOURCE_GROUPS` property of
|
|
``2,gpus:2;gpus:4,gpus:1,crypto_chips:2``.
|
|
|
|
The following variables are passed to the test process:
|
|
|
|
.. envvar:: CTEST_RESOURCE_GROUP_COUNT
|
|
|
|
The total number of groups specified by the :prop_test:`RESOURCE_GROUPS`
|
|
property. For example:
|
|
|
|
* ``CTEST_RESOURCE_GROUP_COUNT=3``
|
|
|
|
This variable will only be defined if :manual:`ctest(1)` has been given a
|
|
``--resource-spec-file``, or if :command:`ctest_test` has been given a
|
|
``RESOURCE_SPEC_FILE``. If no resource specification file has been given,
|
|
this variable will not be defined.
|
|
|
|
.. envvar:: CTEST_RESOURCE_GROUP_<num>
|
|
|
|
The list of resource types allocated to each group, with each item
|
|
separated by a comma. ``<num>`` is a number from zero to
|
|
``CTEST_RESOURCE_GROUP_COUNT`` minus one. ``CTEST_RESOURCE_GROUP_<num>``
|
|
is defined for each ``<num>`` in this range. For example:
|
|
|
|
* ``CTEST_RESOURCE_GROUP_0=gpus``
|
|
* ``CTEST_RESOURCE_GROUP_1=gpus``
|
|
* ``CTEST_RESOURCE_GROUP_2=crypto_chips,gpus``
|
|
|
|
.. envvar:: CTEST_RESOURCE_GROUP_<num>_<resource-type>
|
|
|
|
The list of resource IDs and number of slots from each ID allocated to each
|
|
group for a given resource type. This variable consists of a series of
|
|
pairs, each pair separated by a semicolon, and with the two items in the pair
|
|
separated by a comma. The first item in each pair is ``id:`` followed by the
|
|
ID of a resource of type ``<resource-type>``, and the second item is
|
|
``slots:`` followed by the number of slots from that resource allocated to
|
|
the given group. For example:
|
|
|
|
* ``CTEST_RESOURCE_GROUP_0_GPUS=id:0,slots:2``
|
|
* ``CTEST_RESOURCE_GROUP_1_GPUS=id:2,slots:2``
|
|
* ``CTEST_RESOURCE_GROUP_2_GPUS=id:1,slots:4;id:3,slots:1``
|
|
* ``CTEST_RESOURCE_GROUP_2_CRYPTO_CHIPS=id:card0,slots:2``
|
|
|
|
In this example, group 0 gets 2 slots from GPU ``0``, group 1 gets 2 slots
|
|
from GPU ``2``, and group 2 gets 4 slots from GPU ``1``, 1 slot from GPU
|
|
``3``, and 2 slots from cryptography chip ``card0``.
|
|
|
|
``<num>`` is a number from zero to ``CTEST_RESOURCE_GROUP_COUNT`` minus one.
|
|
``<resource-type>`` is the name of a resource type, converted to uppercase.
|
|
``CTEST_RESOURCE_GROUP_<num>_<resource-type>`` is defined for the product
|
|
of each ``<num>`` in the range listed above and each resource type listed in
|
|
``CTEST_RESOURCE_GROUP_<num>``.
|
|
|
|
Because some platforms have case-insensitive names for environment variables,
|
|
the names of resource types may not clash in a case-insensitive environment.
|
|
Because of this, for the sake of simplicity, all resource types must be
|
|
listed in all lowercase in the
|
|
:ref:`resource specification file <ctest-resource-specification-file>` and
|
|
in the :prop_test:`RESOURCE_GROUPS` property, and they are converted to all
|
|
uppercase in the ``CTEST_RESOURCE_GROUP_<num>_<resource-type>`` environment
|
|
variable.

Dynamically-Generated Resource Specification File
|
|
-------------------------------------------------
|
|
|
|
.. versionadded:: 3.28
|
|
|
|
A project may optionally specify a single test which will be used to
|
|
dynamically generate the resource specification file that CTest will use for
|
|
scheduling tests that use resources. The test that generates the file must
|
|
have the :prop_test:`GENERATED_RESOURCE_SPEC_FILE` property set, and must have
|
|
exactly one fixture in its :prop_test:`FIXTURES_SETUP` property. This fixture
|
|
is considered by CTest to have special meaning: it's the fixture that generates
|
|
the resource spec file. The fixture may have any name. If such a fixture
|
|
exists, all tests that have :prop_test:`RESOURCE_GROUPS` set must have the
|
|
fixture in their :prop_test:`FIXTURES_REQUIRED`, and a resource spec file may
|
|
not be specified with the ``--resource-spec-file`` argument or the
|
|
:variable:`CTEST_RESOURCE_SPEC_FILE` variable.

Job Server Integration
|
|
======================
|
|
|
|
.. versionadded:: 3.29
|
|
|
|
On POSIX systems, when running under the context of a `Job Server`_,
|
|
CTest shares its job slots. This is independent of the :prop_test:`PROCESSORS`
|
|
test property, which still counts against CTest's :option:`-j <ctest -j>`
|
|
parallel level. CTest acquires exactly one token from the job server before
|
|
running each test, and returns it when the test finishes.
|
|
|
|
For example, consider the ``Makefile``:
|
|
|
|
.. literalinclude:: CTEST_EXAMPLE_MAKEFILE_JOB_SERVER.make
|
|
:language: make
|
|
|
|
When invoked via ``make -j 2 test``, ``ctest`` connects to the job server,
|
|
acquires a token for each test, and runs at most 2 tests concurrently.
|
|
|
|
On Windows systems, job server integration is not yet implemented.
