#[=======================================================================[.rst:
Catch
-----
This module defines a function to help use the Catch test framework.
The :command:`catch_discover_tests` discovers tests by asking the compiled test
executable to enumerate its tests. This does not require CMake to be re-run
when tests change. However, it may not work in a cross-compiling environment,
and setting test properties is less convenient.
This command is intended to replace use of :command:`add_test` to register
tests, and will create a separate CTest test for each Catch test case. Note
that this is in some cases less efficient, as common set-up and tear-down logic
cannot be shared by multiple test cases executing in the same instance.
However, it provides more fine-grained pass/fail information to CTest, which is
usually considered as more beneficial. By default, the CTest test name is the
same as the Catch name; see also ``TEST_PREFIX`` and ``TEST_SUFFIX``.
.. command:: catch_discover_tests
Automatically add tests with CTest by querying the compiled test executable
for available tests::
catch_discover_tests(target
[TEST_SPEC arg1...]
[EXTRA_ARGS arg1...]
[WORKING_DIRECTORY dir]
[TEST_PREFIX prefix]
[TEST_SUFFIX suffix]
[PROPERTIES name1 value1...]
[TEST_LIST var]
)
``catch_discover_tests`` sets up a post-build command on the test executable
that generates the list of tests by parsing the output from running the test
with the ``--list-test-names-only`` argument. This ensures that the full
list of tests is obtained. Since test discovery occurs at build time, it is
not necessary to re-run CMake when the list of tests changes.
However, it requires that :prop_tgt:`CROSSCOMPILING_EMULATOR` is properly set
in order to function in a cross-compiling environment.
Additionally, setting properties on tests is somewhat less convenient, since
the tests are not available at CMake time. Additional test properties may be
assigned to the set of tests as a whole using the ``PROPERTIES`` option. If
more fine-grained test control is needed, custom content may be provided
through an external CTest script using the :prop_dir:`TEST_INCLUDE_FILES`
directory property. The set of discovered tests is made accessible to such a
script via the ``<target>_TESTS`` variable.
The options are:
``target``
Specifies the Catch executable, which must be a known CMake executable
target. CMake will substitute the location of the built executable when
running the test.
``TEST_SPEC arg1...``
Specifies test cases, wildcarded test cases, tags and tag expressions to
pass to the Catch executable with the ``--list-test-names-only`` argument.
``EXTRA_ARGS arg1...``
Any extra arguments to pass on the command line to each test case.
``WORKING_DIRECTORY dir``
Specifies the directory in which to run the discovered test cases. If this
option is not provided, the current binary directory is used.
``TEST_PREFIX prefix``
Specifies a ``prefix`` to be prepended to the name of each discovered test
case. This can be useful when the same test executable is being used in
multiple calls to ``catch_discover_tests()`` but with different
``TEST_SPEC`` or ``EXTRA_ARGS``.
``TEST_SUFFIX suffix``
Similar to ``TEST_PREFIX`` except the ``suffix`` is appended to the name of
every discovered test case. Both ``TEST_PREFIX`` and ``TEST_SUFFIX`` may
be specified.
``PROPERTIES name1 value1...``
Specifies additional properties to be set on all tests discovered by this
invocation of ``catch_discover_tests``.
``TEST_LIST var``
Make the list of tests available in the variable ``var``, rather than the
default ``<target>_TESTS``. This can be useful when the same test
executable is being used in multiple calls to ``catch_discover_tests()``.
Note that this variable is only available in CTest.

/**
* Terminology:
*
* Support point:
* The point on the model surface that needs support.
*
* Pillar:
* A thick column that spans from a support point to the ground and has
* a thick cone shaped base where it touches the ground.
*
* Ground facing support point:
* A support point that can be directly connected with the ground with a pillar
* that does not collide or cut through the model.
*
* Non ground facing support point:
* A support point that cannot be directly connected with the ground (only with
* the model surface).
*
* Head:
* The pinhead that connects to the model surface with the sharp end end
* to a pillar or bridge stick with the dull end.
*
* Headless support point:
* A support point on the model surface for which there is not enough place for
* the head. It is either in a hole or there is some barrier that would collide
* with the head geometry. The headless support point can be ground facing and
* non ground facing as well.
*
* Bridge:
* A stick that connects two pillars or a head with a pillar.
*
* Junction:
* A small ball in the intersection of two or more sticks (pillar, bridge, ...)
*
* CompactBridge:
* A bridge that connects a headless support point with the model surface or a
* nearby pillar.
