PASS_REGULAR_EXPRESSION
|
|
-----------------------
|
|
|
|
The test output (stdout or stderr) must match this regular expression
|
|
for the test to pass. The process exit code is ignored. Tests that exceed
|
|
the timeout specified by :prop_test:`TIMEOUT` still fail regardless of
|
|
``PASS_REGULAR_EXPRESSION``. System-level test failures including
|
|
segmentation faults, signal abort, or heap errors may fail the test even
|
|
if ``PASS_REGULAR_EXPRESSION`` is matched.
|
|
|
|
Example:
|
|
|
|
.. code-block:: cmake
|
|
|
|
add_test(NAME mytest COMMAND ${CMAKE_COMMAND} -E echo "Passed this test")
|
|
|
|
set_property(TEST mytest PROPERTY
|
|
PASS_REGULAR_EXPRESSION "pass;Passed"
|
|
)
|
|
|
|
``PASS_REGULAR_EXPRESSION`` expects a list of regular expressions.
|
|
|
|
To run a test that may have a system-level failure, but still pass if
|
|
``PASS_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 PROPERTY_REGULAR_EXPRESSION "pass;Passed")
|
|
|
|
.. code-block:: c
|
|
|
|
#include <signal.h>
|
|
#include <stdio.h>
|
|
|
|
int main(void){
|
|
fprintf(stdout, "Passed\n");
|
|
fflush(stdout); /* ensure the output buffer is seen */
|
|
raise(SIGABRT);
|
|
return 0;
|
|
}
|
|
|
|

|
