Create a test driver and source list for building test programs.
.. code-block:: cmake
create_test_sourcelist(<sourceListName> <driverName>
<tests> ...
[EXTRA_INCLUDE <include>]
[FUNCTION <function>])
A test driver is a program that links together many small tests into a single
executable. This is useful when building static executables with large
libraries to shrink the total required size. The list of source files needed
to build the test driver will be in ``sourceListName``. ``driverName`` is the
name of the test driver program. The rest of the arguments consist of a list
of test source files and can be semicolon separated. Each test source file
should have a function in it that is the same name as the file with no
extension (``foo.cxx`` should have ``int foo(int, char*[]);``). ``driverName``
will be able to call each of the tests by name on the command line. If
``EXTRA_INCLUDE`` is specified, then the next argument is included into the
generated file. If ``FUNCTION`` is specified, then the next argument is taken
as a function name that is passed pointers to ``argc`` and ``argv``. This can
be used to add extra command line processing to each test. The
``CMAKE_TESTDRIVER_BEFORE_TESTMAIN`` cmake variable can be set to have code
that will be placed directly before calling the test ``main`` function.
``CMAKE_TESTDRIVER_AFTER_TESTMAIN`` can be set to have code that will be
placed directly after the call to the test ``main`` function.
Create a test driver program that links together many small tests into a
single executable. This is useful when building static executables with
large libraries to shrink the total required size.
.. signature::
create_test_sourcelist(<sourceListName> <driverName> <test>... <options>...)
:target: original
Generate a test driver source file from a list of individual test sources
and provide a combined list of sources that can be built as an executable.
The options are:
``<sourceListName>``
The name of a variable in which to store the list of source files needed
to build the test driver. The list will contain the ``<test>...`` sources
and the generated ``<driverName>`` source.
.. versionchanged:: 3.29
The test driver source is listed by absolute path in the build tree.
Previously it was listed only as ``<driverName>``.
``<driverName>``
Name of the test driver source file to be generated into the build tree.
The source file will contain a ``main()`` program entry point that
dispatches to whatever test is named on the command line.
``<test>...``
Test source files to be added to the driver binary. Each test source
file must have a function in it that is the same name as the file with the
extension removed. For example, a ``foo.cxx`` test source might contain:
.. code-block:: c++
int foo(int argc, char** argv)
``EXTRA_INCLUDE <header>``
Specify a header file to ``#include`` in the generated test driver source.
``FUNCTION <function>``
Specify a function to be called with pointers to ``argc`` and ``argv``.
The function may be provided in the ``EXTRA_INCLUDE`` header:
.. code-block:: c++
void function(int* pargc, char*** pargv)
This can be used to add extra command line processing to each test.
Additionally, some CMake variables affect test driver generation:
.. variable:: CMAKE_TESTDRIVER_BEFORE_TESTMAIN
Code to be placed directly before calling each test's function.
.. variable:: CMAKE_TESTDRIVER_AFTER_TESTMAIN
Code to be placed directly after the call to each test's function.

Property Redefinition
^^^^^^^^^^^^^^^^^^^^^
Once a property is defined for a particular type of scope, it cannot be
redefined. Attempts to redefine an existing property by calling
:command:`define_property` with the same scope type and property name
will be silently ignored. Defining the same property name for two different
kinds of scope is valid.
:command:`get_property` can be used to determine whether a property is
already defined for a particular kind of scope, and if so, to examine its
definition. For example:
.. code-block:: cmake
# Initial definition

)
# Later examination

gathers their ``INTERFACE`` link targets. If any such targets either were
found with :command:`find_package` or have the
:prop_tgt:`EXPORT_FIND_PACKAGE_NAME` property set, and such package

manually specified by passing ``ENABLED ON`` to :command:`export(SETUP)`
are also added, even if the exported targets don't depend on any targets
from them.

Job Server Integration
======================

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.
