WILL_FAIL
|
|
---------
|
|
|
|
If ``true``, inverts the pass / fail test criteria. Tests for which
|
|
``WILL_FAIL`` is ``true`` fail with return code 0 and pass with non-zero
|
|
return code. Tests that exceed the timeout specified by :prop_test:`TIMEOUT`
|
|
still fail regardless of ``WILL_FAIL``.
|
|
System-level test failures including segmentation faults,
|
|
signal abort, or heap errors may fail the test even if ``WILL_FAIL`` is true.
|
|
|
|
Example of a test that would ordinarily pass, but fails because ``WILL_FAIL``
|
|
is ``true``:
|
|
|
|
.. code-block:: cmake
|
|
|
|
add_test(NAME failed COMMAND ${CMAKE_COMMAND} -E true)
|
|
set_property(TEST failed PROPERTY WILL_FAIL true)
|
|
|
|
To run a test that may have a system-level failure, but still pass if
|
|
``WILL_FAIL`` is set, use a CMake command to wrap the executable run.
|
|
Note that this will prevent automatic handling of the
|
|
:prop_tgt:`CROSSCOMPILING_EMULATOR` and :prop_tgt:`TEST_LAUNCHER`
|
|
target property.
|
|
|
|
.. code-block:: cmake
|
|
|
|
add_executable(main main.c)
|
|
|
|
add_test(NAME sigabrt COMMAND ${CMAKE_COMMAND} -E env $<TARGET_FILE:main>)
|
|
|
|
set_property(TEST sigabrt PROPERTY WILL_FAIL TRUE)
|
|
|
|
.. code-block:: c
|
|
|
|
#include <signal.h>
|
|
|
|
int main(void){ raise(SIGABRT); return 0; }
