add_test

|
|
|
--------
|
|
|
|
|
|
|
|
|
|
Add a test to the project to be run by :manual:`ctest(1)`.
|
|
|
|
|
|
|
|
|
|
::
|
|
|
|
|
|
|
|
|
|
add_test(NAME <name> COMMAND <command> [<arg>...]
|
|
|
|
|
[CONFIGURATIONS <config>...]
|
|
|
|
|
[WORKING_DIRECTORY <dir>])
|
|
|
|
|
|
|
|
|
|
Add a test called ``<name>``. The test name may not contain spaces,
|
|
|
|
|
quotes, or other characters special in CMake syntax. The options are:
|
|
|
|
|
|
|
|
|
|
``COMMAND``
|
|
|
|
|
Specify the test command-line. If ``<command>`` specifies an
|
|
|
|
|
executable target (created by :command:`add_executable`) it will
|
|
|
|
|
automatically be replaced by the location of the executable created
|
|
|
|
|
at build time.
|
|
|
|
|
|
|
|
|
|
``CONFIGURATIONS``
|
|
|
|
|
Restrict execution of the test only to the named configurations.
|
|
|
|
|
|
|
|
|
|
``WORKING_DIRECTORY``
|
|
|
|
|
Set the :prop_test:`WORKING_DIRECTORY` test property to
|
|
|
|
|
specify the working directory in which to execute the test.
|
|
|
|
|
If not specified the test will be run with the current working
|
|
|
|
|
directory set to the build directory corresponding to the
|
|
|
|
|
current source directory.
|
|
|
|
|
|
|
|
|
|
The given test command is expected to exit with code ``0`` to pass and
|
|
|
|
|
non-zero to fail, or vice-versa if the :prop_test:`WILL_FAIL` test
|
|
|
|
|
property is set. Any output written to stdout or stderr will be
|
|
|
|
|
captured by :manual:`ctest(1)` but does not affect the pass/fail status
|
|
|
|
|
unless the :prop_test:`PASS_REGULAR_EXPRESSION` or
|
|
|
|
|
:prop_test:`FAIL_REGULAR_EXPRESSION` test property is used.
|
|
|
|
|
|
|
|
|
|
The ``COMMAND`` and ``WORKING_DIRECTORY`` options may use "generator
|
|
|
|
|
expressions" with the syntax ``$<...>``. See the
|
|
|
|
|
:manual:`cmake-generator-expressions(7)` manual for available expressions.
|
|
|
|
|
|
|
|
|
|
Example usage::
|
|
|
|
|
|
|
|
|
|
add_test(NAME mytest
|
|
|
|
|
COMMAND testDriver --config $<CONFIGURATION>
|
|
|
|
|
--exe $<TARGET_FILE:myexe>)
|
|
|
|
|
|
|
|
|
|
This creates a test ``mytest`` whose command runs a ``testDriver`` tool
|
|
|
|
|
passing the configuration name and the full path to the executable
|
|
|
|
|
file produced by target ``myexe``.
|
|
|
|
|
|
|
|
|
|
.. note::
|
|
|
|
|
|
|
|
|
|
CMake will generate tests only if the :command:`enable_testing`
|
|
|
|
|
command has been invoked. The :module:`CTest` module invokes the
|
|
|
|
|
command automatically when the ``BUILD_TESTING`` option is ``ON``.

add_test(<name> <command> [<arg>...])
|
|
|
|
|
|
|
|
|
|
Add a test called ``<name>`` with the given command-line. Unlike
|
|
|
|
|
the above ``NAME`` signature no transformation is performed on the
|
|
|
|
|
command-line to support target names or generator expressions.
