1Upgrade testing with MCUmgr
2###########################
3
4This application is based on :ref:`smp_svr_sample`. It is built
5using **sysbuild**. Tests are automated with pytest, a new harness of Twister
6(more information can be found :ref:`here <integration_with_pytest>`)
7
8.. note::
9   Pytest uses the MCUmgr fixture which requires the ``mcumgr`` available
10   in the system PATH.
11   More information about MCUmgr can be found here :ref:`mcu_mgr`.
12
13To run tests with Twister on ``nrf52840dk/nrf52840`` platform,
14use following command:
15
16.. code-block:: console
17
18    ./zephyr/scripts/twister -vv --west-flash --enable-slow -T zephyr/tests/boot/with_mcumgr \
19    -p nrf52840dk/nrf52840 --device-testing --device-serial /dev/ttyACM0
20
21.. note::
22   Twister requires ``--west-flash`` flag enabled to use sysbuild.
23
24To test with ``mcumgr`` with Bluetooth, one must add ``usb_hci:hciX`` fixture
25where ``hciX`` is the Bluetooth HCI device (e.g. ``hci1``).
26Fixture can be added to Twister command: ``-X usb_hci:hci1``,
27or added to the hardware map
28
29.. code-block:: yaml
30
31      - connected: true
32        fixtures:
33          - usb_hci:hci1
34
35Test scripts can be found in ``pytest`` directory. To list available
36scenarios with described procedures, one can use a pytest command:
37
38.. code-block:: console
39
40    pytest zephyr/tests/boot/with_mcumgr/pytest --collect-only -v
