``MYVAR``.
- ``path_list_append``: Appends singular ``VALUE`` to the current value of
``MYVAR`` using the host platform's path list separator (``;`` on Windows
and ``:`` elsewhere).
- ``path_list_prepend``: Prepends singular ``VALUE`` to the current value of
``MYVAR`` using the host platform's path list separator (``;`` on Windows
and ``:`` elsewhere).
- ``cmake_list_append``: Appends singular ``VALUE`` to the current value of
``MYVAR`` using ``;`` as the separator.
- ``cmake_list_prepend``: Prepends singular ``VALUE`` to the current value of
``MYVAR`` using ``;`` as the separator.
Unrecognized ``OP`` values will result in the test failing before it is
executed. This is so that future operations may be added without changing
valid behavior of existing tests.
The environment changes from this property do not affect other tests.
FAIL_REGULAR_EXPRESSION
-----------------------
If the output matches this regular expression the test will fail,
regardless of the process exit code.
If set, if the output matches one of specified regular expressions,
the test will fail. Example:
.. code-block:: cmake
set_tests_properties(mytest PROPERTIES
FAIL_REGULAR_EXPRESSION "[^a-z]Error;ERROR;Failed"
)
``FAIL_REGULAR_EXPRESSION`` expects a list of regular expressions.
See also the :prop_test:`PASS_REGULAR_EXPRESSION` and
:prop_test:`SKIP_REGULAR_EXPRESSION` test properties.
FIXTURES_CLEANUP
----------------
.. versionadded:: 3.7
Specifies a list of fixtures for which the test is to be treated as a cleanup
test. These fixture names are distinct from test case names and are not
required to have any similarity to the names of tests associated with them.
Fixture cleanup tests are ordinary tests with all of the usual test
functionality. Setting the ``FIXTURES_CLEANUP`` property for a test has two
primary effects:
- CTest will ensure the test executes after all other tests which list any of
the fixtures in its :prop_test:`FIXTURES_REQUIRED` property.
- If CTest is asked to run only a subset of tests (e.g. using regular
expressions or the ``--rerun-failed`` option) and the cleanup test is not in
the set of tests to run, it will automatically be added if any tests in the
set require any fixture listed in ``FIXTURES_CLEANUP``.
A cleanup test can have multiple fixtures listed in its ``FIXTURES_CLEANUP``
property. It will execute only once for the whole CTest run, not once for each
fixture. A fixture can also have more than one cleanup test defined. If there
are multiple cleanup tests for a fixture, projects can control their order with
the usual :prop_test:`DEPENDS` test property if necessary.
A cleanup test is allowed to require other fixtures, but not any fixture listed
in its ``FIXTURES_CLEANUP`` property. For example:
.. code-block:: cmake
# Ok: Dependent fixture is different to cleanup
set_tests_properties(cleanupFoo PROPERTIES
FIXTURES_CLEANUP Foo
FIXTURES_REQUIRED Bar
)
# Error: cannot require same fixture as cleanup
set_tests_properties(cleanupFoo PROPERTIES
FIXTURES_CLEANUP Foo
FIXTURES_REQUIRED Foo
)
Cleanup tests will execute even if setup or regular tests for that fixture fail
or are skipped.
See :prop_test:`FIXTURES_REQUIRED` for a more complete discussion of how to use
test fixtures.
FIXTURES_REQUIRED
-----------------
.. versionadded:: 3.7
Specifies a list of fixtures the test requires. Fixture names are case
sensitive and they are not required to have any similarity to test names.
Fixtures are a way to attach setup and cleanup tasks to a set of tests. If a
test requires a given fixture, then all tests marked as setup tasks for that
fixture will be executed first (once for the whole set of tests, not once per
test requiring the fixture). After all tests requiring a particular fixture
have completed, CTest will ensure all tests marked as cleanup tasks for that
fixture are then executed. Tests are marked as setup tasks with the
:prop_test:`FIXTURES_SETUP` property and as cleanup tasks with the
