SYNOPSIS

ctest [<options>]
ctest <path-to-source> <path-to-build> --build-generator <generator>
      [<options>...] [-- <build-options>...] [--test-command <test>]
ctest {-D <dashboard> | -M <model> -T <action> | -S <script> | -SP <script>}
      [-- <dashboard-options>...]

DESCRIPTION

The “ctest” executable is the CMake test driver program. CMake-generated build trees created for projects that use the ENABLE_TESTING and ADD_TEST commands have testing support. This program will run the tests and report results.

OPTIONS

-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”.

--progress
    Enable short progress output from tests.

    When the output of 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 CTEST_PROGRESS_OUTPUT.

-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.

-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.

--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.

--output-on-failure
    Output anything outputted by the test program if the test should fail. This option can also be enabled by setting the CTEST_OUTPUT_ON_FAILURE environment variable

-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.

-j <jobs>, --parallel <jobs>
    Run the tests in parallel using the given number of jobs.

    This option tells CTest to run the tests in parallel using given number of jobs. This option can also be set by setting the CTEST_PARALLEL_LEVEL environment variable.

    This option can be used with the PROCESSORS test property.

    See Label and Subproject Summary.

--test-load <level>
    While running tests in parallel (e.g. with -j), try not to start tests when they may cause the CPU load to pass above a given threshold.

    When ctest is run as a Dashboard Client this sets the TestLoad option of the CTest Test Step.

-Q,--quiet
    Make CTest quiet.

    This option will suppress all the output. The output log file will still be generated if the --output-log is specified. Options such as --verbose, --extra-verbose, and --debug are ignored if --quiet is specified.

-O <file>, --output-log <file>
    Output to log file.

    This option tells CTest to write all its output to a log file.

-N,--show-only
    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 -R and -E options.

-L <regex>, --label-regex <regex>
    Run tests with labels matching regular expression.

    This option tells CTest to run only the tests whose labels match the given regular expression.

-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.

-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.

-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.

-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.

-FS <regex>, --fixture-exclude-setup <regex>
    Same as -FA except only matching setup tests are excluded.

-FC <regex>, --fixture-exclude-cleanup <regex>
    Same as -FA except only matching cleanup tests are excluded.

-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.

    See Dashboard Client.

-D <var>:<type>=<value>
    Define a variable for script mode.

    Pass in variable values on the command line. Use in conjunction with -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.

-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 -T is similar to -D.

    See Dashboard Client.

-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 -M and -T is similar to -D.

    See Dashboard Client.

-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 ctest -D with the appropriate options.

    See Dashboard Client.

-SP <script>, --script-new-process <script>
    Execute a dashboard for a configuration.

    This option does the same operations as -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 -S scripts.

    See Dashboard Client.

-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.

-U, --union
    Take the Union of -I and -R.

    When both -R and -I are specified by default the intersection of tests are run. By specifying -U the union of tests is run instead.

--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 (-L, -R, -E, -LE, -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).

--repeat-until-fail <n>
    Require each test to run <n> times without failing in order to pass.

    This is useful in finding sporadic failures in test cases.

--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.

--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. On Windows this means that in non-interactive mode, all system debug pop up windows are blocked. In dashboard mode (Experimental, Nightly, Continuous), the default is non-interactive. When just running tests not for a dashboard the default is to allow popups and interactive debugging.

--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.

--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.

    --build-and-test See Build and Test Mode.

--test-output-size-passed <size>
    Limit the output for passed tests to <size> bytes.

--test-output-size-failed <size>
    Limit the output for failed tests to <size> bytes.

--overwrite
    Overwrite CTest configuration option.

    By default CTest uses configuration options from configuration file. This option will overwrite the configuration 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.

--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.

--submit-index
    Legacy option for old Dart2 dashboard server feature. Do not use.

--timeout <seconds>
    Set a global timeout on all tests.

    This option will set a global timeout on all tests that do not already have a timeout set on them.

--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.

--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.

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.

When the 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 ith test for the jth label or subproject

•   num_processors[j,i]: Value of the CTest PROCESSORS property for the ith test for the jth label or subproject

•   num_tests[j]: Number of tests associated with the jth 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

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:

--build-target
    Specify a specific target to build.

    If left out the all target is built.

--build-nocmake
    Run the build without running cmake first.

    Skip the cmake step.

--build-run-dir
    Specify directory to run programs from.

    Directory where programs will be after it has been compiled.

--build-two-config
    Run CMake twice.

--build-exe-dir
    Specify the directory for the executable.

--build-generator
    Specify the generator to use. See the cmake-generators(7) manual.

--build-generator-platform
    Specify the generator-specific platform.

--build-generator-toolset
    Specify the generator-specific toolset.

--build-project
    Specify the name of the project to build.

--build-makeprogram
    Override the make program chosen by CTest with a given one.

--build-noclean
    Skip the make clean step.

--build-config-sample
    A sample executable to use to determine the configuration that should be used. e.g. Debug/Release/etc.

--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.

--test-command
    The command to run as the test step with the --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.

--test-timeout
    The time limit in seconds

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> | -M <model> -T <action> | -S <script> | -SP <script>)
      [-- <dashboard-options>...]

Options for Dashboard Client include:

--track <track>
    Specify the track to submit dashboard to

    Submit dashboard to specified track instead of default one. By default, the dashboard is submitted to Nightly, Experimental, or Continuous track, but by specifying this option, the track can be arbitrary.

-A <file>, --add-notes <file>
    Add a notes file with submission.

    This option tells CTest to include a notes file when submitting dashboard.

--tomorrow-tag
    Nightly or experimental starts with next day tag.

    This is useful if the build will not finish in one day.

--extra-submit <file>[;<file>]
    Submit extra files to the dashboard.

    This option will submit extra files to the dashboard.

--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.

--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 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 CTest module if included by the project. The module uses variables to obtain a value for each setting as documented with the settings below.

  Dashboard Client via CTest Script

CTest can perform testing driven by a cmake-language(7) script that creates and maintains the source and build tree as well as performing the testing steps. Run the 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 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

Start a new dashboard submission to be composed of results recorded by the following steps.

In a CTest Script, the 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:

BuildDirectory
    The full path to the project build tree.

•   CTest Script variable: CTEST_BINARY_DIRECTORY

•   CTest module variable: PROJECT_BINARY_DIR

SourceDirectory
    The full path to the project source tree.

•   CTest Script variable: CTEST_SOURCE_DIRECTORY

•   CTest module variable: PROJECT_SOURCE_DIR

  CTest Update Step

In a CTest Script, the ctest_update() command runs this step. Arguments to the command may specify some of the step settings.
