Twister: How to prevent testcase skipped when harness is keyboard?(SKIPPED: Not runnable on device)

[SawXu]

Question

I want to figure out how to setup harness "keyboard" and make test cases about it to work.

Project

zephyr/tests/drivers/uart/uart_basic_api/testcase.yaml

source code:

tests:
  drivers.uart.basic_api:
    tags: drivers
    filter: CONFIG_UART_CONSOLE
    harness: keyboard
    integration_platforms:
      - mps2_an385
  drivers.uart.basic_api.poll:
    extra_args: CONF_FILE=prj_poll.conf
    tags: drivers
    filter: CONFIG_UART_CONSOLE
    harness: keyboard
    integration_platforms:
      - mps2_an385
  drivers.uart.basic_api.shell:
    extra_args: CONF_FILE=prj_shell.conf
    min_flash: 64
    tags: drivers
    filter: CONFIG_UART_CONSOLE
    harness: keyboard
    integration_platforms:
      - mps2_an385
  drivers.uart.basic_api.cdc_acm:
    extra_args: OVERLAY_CONFIG="overlay-usb.conf"
                DTC_OVERLAY_FILE="usb.overlay"
    tags: drivers usb
    filter: CONFIG_UART_CONSOLE
    depends_on: usb_device
    harness: keyboard

Steps

I run this test case use :
./zephyr/scripts/twister --device-testing --device-serial /dev/ttyACM0 -W -p frdm_k64f -T zephyr/tests/drivers/uart/uart_basic_api/ --west-flash --west-runner=pyocd -v --verbose

And the log show :

INFO    - Building initial testsuite list...
DEBUG   - frdm_k64f                 tests/drivers/uart/uart_basic_api/drivers.uart.basic_api SKIPPED: Not runnable on device
DEBUG   - frdm_k64f                 tests/drivers/uart/uart_basic_api/drivers.uart.basic_api.poll SKIPPED: Not runnable on device
DEBUG   - frdm_k64f                 tests/drivers/uart/uart_basic_api/drivers.uart.basic_api.shell SKIPPED: Not runnable on device
DEBUG   - frdm_k64f                 tests/drivers/uart/uart_basic_api/drivers.uart.basic_api.cdc_acm SKIPPED: Not runnable on device

I want this test case to run. And how could I setup this "keyboard" harness? Thanks lot.
