HI Kyle,
Where are the -D and the -P switches of add_test documented?
Thanks for the suggestion.

I have a test where I start a program that I know will create some

But I have no way to kill this program, so I let Ctest kill it with

TIMEOUT.
The next step greps the output to see if it worked.
So it would be nice if PASS_REGULAR_EXPRESSION could override
TIMEOUT
and not mark the test as failed.
For example:
set_tests_properties(${importMaps} PROPERTIES
PASS_REGULAR_EXPRESSION "some string I know I will find")
# this
^^^^^^^^^^^^^^^^^^^^^^ makes the test pass even if it times out
set_tests_properties(${importMaps} PROPERTIES TIMEOUT 60)
You could wrap your test in a CMake script that calls execute_process()
with a TIMEOUT argument, and then greps the output of the command for
the desired expression. For example:
CMakeLists.txt:
add_test(NAME mytest COMMAND ${CMAKE_COMMAND} -DMYEXE=${PATH_TO_MYEXE}
-P ${CMAKE_CURRENT_LIST_DIR}/ExecuteTest.cmake)
ExecuteTest.cmake:
execute_process(COMMAND ${PATH_TO_MYEXE} TIMEOUT 60 OUTPUT_VARIABLE
output)
if(NOT output MATCHES "^my_desired_regex$")
message(FATAL_ERROR "myexe did not produce desired output")
endif()
Hope that helps
Kyle
