ctest_start
-----------
Starts the testing for a given model
::
ctest_start(<model> [<source> [<binary>]] [GROUP <group>] [QUIET])
ctest_start([<model> [<source> [<binary>]]] [GROUP <group>] APPEND [QUIET])
Starts the testing for a given model. The command should be called
after the binary directory is initialized.
The parameters are as follows:
``<model>``
Set the dashboard model. Must be one of ``Experimental``, ``Continuous``, or
``Nightly``. This parameter is required unless ``APPEND`` is specified.
``<source>``
Set the source directory. If not specified, the value of
:variable:`CTEST_SOURCE_DIRECTORY` is used instead.
``<binary>``
Set the binary directory. If not specified, the value of
:variable:`CTEST_BINARY_DIRECTORY` is used instead.
``GROUP <group>``
If ``GROUP`` is used, the submissions will go to the specified group on the
CDash server. If no ``GROUP`` is specified, the name of the model is used by
default.
.. versionchanged:: 3.16
This replaces the deprecated option ``TRACK``. Despite the name
change its behavior is unchanged.
``APPEND``
If ``APPEND`` is used, the existing ``TAG`` is used rather than creating a new
one based on the current time stamp. If you use ``APPEND``, you can omit the
``<model>`` and ``GROUP <group>`` parameters, because they will be read from
the generated ``TAG`` file. For example:
.. code-block:: cmake
ctest_start(Experimental GROUP GroupExperimental)
Later, in another ``ctest -S`` script:
.. code-block:: cmake
ctest_start(APPEND)
When the second script runs ``ctest_start(APPEND)``, it will read the
``Experimental`` model and ``GroupExperimental`` group from the ``TAG`` file
generated by the first ``ctest_start()`` command. Please note that if you
call ``ctest_start(APPEND)`` and specify a different model or group than
in the first ``ctest_start()`` command, a warning will be issued, and the
new model and group will be used.
``QUIET``
.. versionadded:: 3.3
If ``QUIET`` is used, CTest will suppress any non-error messages that it
otherwise would have printed to the console.
The parameters for ``ctest_start()`` can be issued in any order, with the
exception that ``<model>``, ``<source>``, and ``<binary>`` have to appear
in that order with respect to each other. The following are all valid and
equivalent:
.. code-block:: cmake
ctest_start(Experimental path/to/source path/to/binary GROUP SomeGroup QUIET APPEND)
ctest_start(GROUP SomeGroup Experimental QUIET path/to/source APPEND path/to/binary)
ctest_start(APPEND QUIET Experimental path/to/source GROUP SomeGroup path/to/binary)
However, for the sake of readability, it is recommended that you order your
parameters in the order listed at the top of this page.
If the :variable:`CTEST_CHECKOUT_COMMAND` variable (or the
:variable:`CTEST_CVS_CHECKOUT` variable) is set, its content is treated as
command-line. The command is invoked with the current working directory set
to the parent of the source directory, even if the source directory already
exists. This can be used to create the source tree from a version control
repository.
