RVC example app

This example app is meant to demonstrate an implementation of a Matter Robotic Vacuum Cleaner device.

State machine

Below is a diagram describing the state machine for this app.

state machine

This app can support most of the tests in the test plans.

Out-of-band messages

Out-of-band messages are available to simulate typical device behaviors and allow the app to navigate to all the states. To send an out-of-band message, echo the JSON message to the /tmp/chip_rvc_fifo_<PID> file. The JSON message must have a "Name" key that contains the command name. This name is shown in the state machine diagram above. Example echo '{"Name": "Charged"}' > /tmp/chip_rvc_fifo_42.

ErrorEvent message

The error event message requires the additional key "Error" which specifies the error state ID. This can be one of UnableToStartOrResume, UnableToCompleteOperation, CommandInvalidInState, FailedToFindChargingDock, Stuck, DustBinMissing, DustBinFull, WaterTankEmpty, WaterTankMissing, WaterTankLidOpen, MopCleaningPadMissing.

Testing

A PICS file that details what this app supports testing is available in the pics directory as a txt file. After building the RVC example app, chip-tool, and setting up the testing environment, python tests can be executed with ./scripts/tests/run_python_test.py --script src/python_testing/<script_name>.py --script-args "--storage-path admin_storage.json --PICS examples/rvc-app/rvc-common/pics/RVC_App_Test_Plan.txt --int-arg <PIXIT_Definitions:1>"

Note: If the testing environment has not been commissioned with the RVC app, use chip-tool to switch on the commissioning window chip-tool pairing open-commissioning-window, and add the following flags to the --script-args above. --commissioning-method on-network --discriminator XXXX --passcode XXXX.

Below are the PIXIT definitions required for the different python tests.

RVC Clean Mode cluster

TC 1.2

PIXIT: PIXIT_ENDPOINT:1
Example command: ./scripts/tests/run_python_test.py --script src/python_testing/TC_RVCCLEANM_1_2.py --script-args "--storage-path admin_storage.json --PICS examples/rvc-app/rvc-common/pics/RVC_App_Test_Plan.txt --int-arg PIXIT_ENDPOINT:1"

TC 2.1

PIXIT: PIXIT_ENDPOINT:1 PIXIT.RVCCLEANM.MODE_CHANGE_FAIL:1 PIXIT.RVCCLEANM.MODE_CHANGE_OK:2
Example command: ./scripts/tests/run_python_test.py --script src/python_testing/TC_RVCCLEANM_2_1.py --script-args "--storage-path admin_storage.json --PICS examples/rvc-app/rvc-common/pics/RVC_App_Test_Plan.txt --int-arg PIXIT_ENDPOINT:1 PIXIT.RVCCLEANM.MODE_CHANGE_FAIL:1 PIXIT.RVCCLEANM.MODE_CHANGE_OK:2"

When asked “Manually put the device in a state from which it will FAIL to transition to mode 1”, set the RvcRunMode to 1. chip-tool rvcrunmode change-to-mode 1

When asked “Manually put the device in a state from which it will SUCCESSFULLY transition to mode 2”, set the RvcRunMode to 0. chip-tool rvcrunmode change-to-mode 0

TC 3.2

This is not applicable because this RVC device does not support the StartUpMode attribute.

RVC Run Mode cluster

TC 1.2

PIXIT: PIXIT_ENDPOINT:1 Example command: ./scripts/tests/run_python_test.py --script src/python_testing/TC_RVCRUNM_1_2.py --script-args "--storage-path admin_storage.json --PICS examples/rvc-app/rvc-common/pics/RVC_App_Test_Plan.txt --int-arg PIXIT_ENDPOINT:1"

TC 2.1

PIXIT: PIXIT_ENDPOINT:1 PIXIT.RVCRUNM.MODE_CHANGE_FAIL:2 PIXIT.RVCRUNM.MODE_CHANGE_OK:0
Example command: ./scripts/tests/run_python_test.py --script src/python_testing/TC_RVCRUNM_2_1.py --script-args "--storage-path admin_storage.json --PICS examples/rvc-app/rvc-common/pics/RVC_App_Test_Plan.txt --int-arg PIXIT_ENDPOINT:1 PIXIT.RVCRUNM.MODE_CHANGE_FAIL:2 PIXIT.RVCRUNM.MODE_CHANGE_OK:0"

When asked “Manually put the device in a state from which it will FAIL to transition to mode 2”, set the RvcRunMode to 1. chip-tool rvcrunmode change-to-mode 1

When asked “Manually put the device in a state from which it will SUCCESSFULLY transition to mode 0”, do nothing.

TC 3.2

This is not applicable because this RVC device does not support the StartUpMode attribute.

RVC Operational State cluster

TC 2.1

PIXIT: PIXIT_ENDPOINT:1
Example command: ./scripts/tests/run_python_test.py --script src/python_testing/TC_RVCOPSTATE_2_1.py --script-args "--storage-path admin_storage.json --PICS examples/rvc-app/rvc-common/pics/RVC_App_Test_Plan.txt --int-arg PIXIT_ENDPOINT:1"

Use the out-of-band messages, chip-tool messages and the state machine diagram to navigate to the required states.

TC 2.3

PIXIT: PIXIT_ENDPOINT:1
Example command: ./scripts/tests/run_python_test.py --script src/python_testing/TC_RVCOPSTATE_2_3.py --script-args "--storage-path admin_storage.json --PICS examples/rvc-app/rvc-common/pics/RVC_App_Test_Plan.txt --int-arg PIXIT_ENDPOINT:1"

Use the out-of-band messages, chip-tool messages and the state machine diagram to transition to the required states.

Running the yaml tests

After commissioning the device, all the yaml tests can be run by running the run_all_yaml_tests.sh script from the root dir with the node ID that the device was commissioned with.
