描述

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.

选项

-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 环境变量。

This option can be used with the PROCESSORS test property.

--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 仪表板客户端 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 ,和 --debug are ignored 若 --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[=<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 -R and -E options.

<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. 见 展示成 JSON 对象模型 .
-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>
如同 -FA except only matching setup tests are excluded.
-FC <regex>, --fixture-exclude-cleanup <regex>
如同 -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.

仪表板客户端 .

-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> 可以是 Experimental , Nightly ,和 Continuous . Combining -M and -T is similar to -D .

仪表板客户端 .

-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 .

仪表板客户端 .

-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.

仪表板客户端 .

-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.

仪表板客户端 .

-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.

--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.

--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 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 TIMEOUT 特性。

--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.

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”).

构建和测试模式

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

仪表板客户端

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. 见 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. 见 CTest Update Step section below.
Configure
Configure the software by running a command in the build tree. Record the configuration output log. 见 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. 见 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. 见 CTest Test Step section below.
Coverage
Compute coverage of the source code by running a coverage analysis tool and recording its output. 见 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. 见 CTest MemCheck Step section below.
Submit
Submit results recorded from other testing steps to the software quality dashboard server. 见 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 ,和 Submit steps by default. Selected steps run even 若 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 ,和 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> ]...
                                            

<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 仪表板客户端配置 settings from a file in the build tree called either CTestConfiguration.ini 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>
                                            

<script> file must call CTest 命令 commands to run testing steps explicitly as documented below. The commands obtain 仪表板客户端配置 settings from their arguments or from variables set in the script.

仪表板客户端配置

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.

SourceDirectory

The full path to the project source tree.

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.

Configuration settings to specify the version control tool include:

BZRCommand

bzr command-line tool to use if source tree is managed by Bazaar.

BZRUpdateOptions

Command-line options to the BZRCommand when updating the source.

CVSCommand

cvs command-line tool to use if source tree is managed by CVS.

CVSUpdateOptions

Command-line options to the CVSCommand when updating the source.

GITCommand

git command-line tool to use if source tree is managed by Git.

The source tree is updated by git fetch followed by git reset --hard FETCH_HEAD . The result is the same as git pull except that any local moficiations are overwritten. Use GITUpdateCustom to specify a different approach.

GITInitSubmodules

If set, CTest will update the repository’s submodules before updating.

GITUpdateCustom

Specify a custom command line (as a semicolon-separated list) to run in the source tree (Git work tree) to update it instead of running the GITCommand .

GITUpdateOptions

Command-line options to the GITCommand when updating the source.

HGCommand

hg command-line tool to use if source tree is managed by Mercurial.

HGUpdateOptions

Command-line options to the HGCommand when updating the source.

P4Client

Value of the -c option to the P4Command .

P4Command

p4 command-line tool to use if source tree is managed by Perforce.

P4Options

Command-line options to the P4Command for all invocations.

P4UpdateCustom

Specify a custom command line (as a semicolon-separated list) to run in the source tree (Perforce tree) to update it instead of running the P4Command .

P4UpdateOptions

Command-line options to the P4Command when updating the source.

SVNCommand

svn command-line tool to use if source tree is managed by Subversion.

SVNOptions

Command-line options to the SVNCommand for all invocations.

SVNUpdateOptions

Command-line options to the SVNCommand when updating the source.

UpdateCommand

Specify the version-control command-line tool to use without detecting the VCS that manages the source tree.

  • CTest module variable: UPDATE_TYPE if set, else CTEST_UPDATE_TYPE
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.

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 Configure Step

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

Configuration settings include:

ConfigureCommand

Command-line to launch the software configuration process. It will be executed in the location specified by the BuildDirectory setting.

LabelsForSubprojects

Specify a semicolon-separated list of labels that will be treated as subprojects. This mapping will be passed on to CDash when configure, test or build results are submitted.

CTest Build Step

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

Configuration settings include:

DefaultCTestConfigurationType

When the build system to be launched allows build-time selection of the configuration (e.g. Debug , Release ), this specifies the default configuration to be built when no -C option is given to the ctest command. The value will be substituted into the value of MakeCommand to replace the literal string ${CTEST_CONFIGURATION_TYPE} if it appears.

LabelsForSubprojects

Specify a semicolon-separated list of labels that will be treated as subprojects. This mapping will be passed on to CDash when configure, test or build results are submitted.

MakeCommand

Command-line to launch the software build process. It will be executed in the location specified by the BuildDirectory setting.

UseLaunchers

For build trees generated by CMake using one of the Makefile 生成器 Ninja generator, specify whether the CTEST_USE_LAUNCHERS feature is enabled by the CTestUseLaunchers module (also included by the 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.

CTest Test Step

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

Configuration settings include:

LabelsForSubprojects

Specify a semicolon-separated list of labels that will be treated as subprojects. This mapping will be passed on to CDash when configure, test or build results are submitted.
