SKIP_REGULAR_EXPRESSION

.. versionadded:: 3.16

If the test output (stderr or stdout) matches this regular expression the test will be marked as skipped, regardless of the process exit code. Tests that exceed the timeout specified by :prop_test:TIMEOUT still fail regardless of SKIP_REGULAR_EXPRESSION. System-level test failures including segmentation faults, signal abort, or heap errors may fail the test even if the regular expression matches.

Example:

.. code-block:: cmake

add_test(NAME mytest COMMAND ${CMAKE_COMMAND} -E echo "Skipped this test")

set_property(TEST mytest PROPERTY SKIP_REGULAR_EXPRESSION "[^a-z]Skip" "SKIP" "Skipped" )

SKIP_REGULAR_EXPRESSION expects a list of regular expressions.

To run a test that may have a system-level failure, but still skip if SKIP_REGULAR_EXPRESSION matches, 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 SKIP_REGULAR_EXPRESSION "SIGABRT;[aA]bort")

.. code-block:: c

#include <signal.h>

int main(void){ raise(SIGABRT); return 0; }
