SEGGER has released a new version of their J-Link tools suite. That suite includes the J-Run utility which loads, executes and monitors the output of the target. Output can be with RTT (Real-Time Transfer) or semihosting. This makes it useful for automated tests with CMake and CTest:

What has been added from the V7.98g release is the ability to send arguments to the running application using the --args command, for example with CMake/CTest:

set (RUNNER_CTEST_COMMAND "$ENV{SEGGER_PATH}/JRun" --verbose --device LPC55S16 --silent --rtt -if SWD)

add_test(
  NAME Led_1
  COMMAND ${RUNNER_CTEST_COMMAND} --args "Led_1" ${TEST_EXECUTABLE}
)

Like applications running on the host, I can now pass arguments to the running application. This is useful to set up the target, or to tell which kind of tests to run.
