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.
