Hello CMake-gurus,
I have defined a test-target in my CMakeLists.txt file like this:
add_test(${TEST_TARGET} ${CMAKE_CTEST_COMMAND}
--extra-verbose
--build-config ${CMAKE_BUILD_TYPE}
--build-and-test ${TESTS_SOURCE_DIR} ${TESTS_BINARY_DIR}
--build-project ${TEST_PROJECT}
--build-target ${TEST_TARGET}
--build-generator ${_bt_generator}
--build-makeprogram ${_bt_makeprogram}
--build-exe-dir ${_exe_dir}
--build-options -DCMAKE_BUILD_TYPE:STRING=${CMAKE_BUILD_TYPE}
--test-command ${TEST_TARGET}
)
And I'm running ctest as a POST_BUILD custom-command. This works very well,
the test build-files are created and the test is built and run.
But there is a difference in running the tests:
1) via "ctest" as in my post-build command or
2) via "make test".
In the first case, the test-output is displayed correctly (which I need,
e.g. to have the line displayed where an assertion in the test has failed).
In the second case, the test-output is not displayed.
I've played around a little to find out, that "make test" calls "ctest
--force-new-ctest-process". If I ommit this parameter, "make test" also
displays the test-output correctly.
Why does --force-new-ctest-process prevents the test-output from beeing
displayed?
Why ist his parameter a default in the global generator?
Cheers!
Marco
