#[=======================================================================[.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.

#[=======================================================================[.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]
[REPORTER reporter]
[OUTPUT_DIR dir]
[OUTPUT_PREFIX prefix]
[OUTPUT_SUFFIX suffix]
[DISCOVERY_MODE <POST_BUILD|PRE_TEST>]
[SKIP_IS_FAILURE]
[ADD_TAGS_AS_LABELS]
)
``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.
``REPORTER reporter``
Use the specified reporter when running the test case. The reporter will
be passed to the Catch executable as ``--reporter reporter``.
``OUTPUT_DIR dir``
If specified, the parameter is passed along as
``--out dir/<test_name>`` to Catch executable. The actual file name is the
same as the test name. This should be used instead of
``EXTRA_ARGS --out foo`` to avoid race conditions writing the result output
when using parallel test execution.
``OUTPUT_PREFIX prefix``
May be used in conjunction with ``OUTPUT_DIR``.
If specified, ``prefix`` is added to each output file name, like so
``--out dir/prefix<test_name>``.
``OUTPUT_SUFFIX suffix``
May be used in conjunction with ``OUTPUT_DIR``.
If specified, ``suffix`` is added to each output file name, like so
``--out dir/<test_name>suffix``. This can be used to add a file extension to
the output e.g. ".xml".
``DL_PATHS path...``
Specifies paths that need to be set for the dynamic linker to find shared
libraries/DLLs when running the test executable (PATH/LD_LIBRARY_PATH respectively).
These paths will both be set when retrieving the list of test cases from the
test executable and when the tests are executed themselves. This requires
cmake/ctest >= 3.22.
``DL_FRAMEWORK_PATHS path...``
Specifies paths that need to be set for the dynamic linker to find libraries
packaged as frameworks on Apple platforms when running the test executable
(DYLD_FRAMEWORK_PATH). These paths will both be set when retrieving the list
of test cases from the test executable and when the tests are executed themselves.
This requires cmake/ctest >= 3.22.
``DISCOVERY_MODE mode``
Provides control over when ``catch_discover_tests`` performs test discovery.
By default, ``POST_BUILD`` sets up a post-build command to perform test discovery
at build time. In certain scenarios, like cross-compiling, this ``POST_BUILD``
behavior is not desirable. By contrast, ``PRE_TEST`` delays test discovery until
just prior to test execution. This way test discovery occurs in the target environment
where the test has a better chance at finding appropriate runtime dependencies.
``DISCOVERY_MODE`` defaults to the value of the
``CMAKE_CATCH_DISCOVER_TESTS_DISCOVERY_MODE`` variable if it is not passed when
calling ``catch_discover_tests``. This provides a mechanism for globally selecting
a preferred test discovery behavior without having to modify each call site.
``SKIP_IS_FAILURE``
Disables skipped test detection.
``ADD_TAGS_AS_LABELS``
Adds all test tags as CTest labels.

# This file provides a way to skip stepping into Catch code when debugging with gdb.
#
# With the gdb "skip" command you can tell gdb to skip files or functions during debugging.
# see https://xaizek.github.io/2016-05-26/skipping-standard-library-in-gdb/ for an example
#
# Basically the following line tells gdb to skip all functions containing the
# regexp "Catch", which matches the complete Catch namespace.
# If you want to skip just some parts of the Catch code you can modify the
# regexp accordingly.
#
# If you want to permanently skip stepping into Catch code copy the following
# line into your ~/.gdbinit file
