FIXTURES_SETUP
--------------
Specifies a list of fixtures for which the test is to be treated as a setup
test.
Fixture setup tests are ordinary tests with all of the usual test
functionality. Setting the ``FIXTURES_SETUP`` property for a test has two
primary effects:
- CTest will ensure the test executes before any other test which lists the
fixture(s) 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 setup 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_SETUP``.
A setup test can have multiple fixtures listed in its ``FIXTURES_SETUP``
property. It will execute only once for the whole CTest run, not once for each
fixture. A fixture can also have more than one setup test defined. If there are
multiple setup tests for a fixture, projects can control their order with the
usual :prop_test:`DEPENDS` test property if necessary.
A setup test is allowed to require other fixtures, but not any fixture listed
in its ``FIXTURES_SETUP`` property. For example:
.. code-block:: cmake
# Ok: dependent fixture is different to setup
set_tests_properties(setupFoo PROPERTIES
FIXTURES_SETUP Foo
FIXTURES_REQUIRED Bar
)
# Error: cannot require same fixture as setup
set_tests_properties(setupFoo PROPERTIES
FIXTURES_SETUP Foo
FIXTURES_REQUIRED Foo
)
If any of a fixture's setup tests fail, none of the tests listing that fixture
in its :prop_test:`FIXTURES_REQUIRED` property will be run. Cleanup tests will,
however, still be executed.
See :prop_test:`FIXTURES_REQUIRED` for a more complete discussion of how to use
test fixtures.
