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] + ) + + ``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 ``_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 ``_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/`` 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``. + + ``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/suffix``.
