Dashboard Client
================
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.
.. _`CDash`: http://cdash.org/
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.
See the `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.
See the `CTest Update Step`_ section below.
``Configure``
Configure the software by running a command in the build tree.
Record the configuration output log.
See the `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.
See the `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.
See the `CTest Test Step`_ section below.
``Coverage``
Compute coverage of the source code by running a coverage
analysis tool and recording its output.
See the `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.
See the `CTest MemCheck Step`_ section below.
``Submit``
Submit results recorded from other testing steps to the
software quality dashboard server.
See the `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``, and ``Submit`` steps by default. Selected steps run even
if the ``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``, and ``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> ]...
The ``<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 `Dashboard Client Configuration`_ settings from
a file in the build tree called either ``CTestConfiguration.ini``
or ``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 :module:`CTest` module if included by the project.
The module uses variables to obtain a value for each setting
as documented with the settings below.
.. _`CTest Script`:
Dashboard Client via CTest Script
---------------------------------
CTest can perform testing driven by a :manual:`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>
The ``<script>`` file must call :ref:`CTest Commands` commands
to run testing steps explicitly as documented below. The commands
obtain `Dashboard Client Configuration`_ settings from their
arguments or from variables set in the script.
Dashboard Client Configuration
==============================
The `Dashboard Client Steps`_ may be configured by named
settings as documented in the following sections.
.. _`CTest Start Step`:

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.

the value of ``MakeCommand`` to replace the literal string
``${CTEST_CONFIGURATION_TYPE}`` if it appears.

or the :generator:`Ninja` generator, specify whether the
``CTEST_USE_LAUNCHERS`` feature is enabled by the
:module:`CTestUseLaunchers` module (also included by the
:module:`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.
