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 ``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.
