[TC-SC-3.6] - Reference app required to make DUT as controller

[somu1710]

Description:

• In Secure channel Test case[TC-SC-3.6], requires to verify DUT’s CaseSessionsPerFabric in CapabilityMinima is at least 3 in 5 different fabrics in which each fabric contains 3 reference devices.

• To execute this test case as it is, requires 15 TH's and one DUT.

• If we develop the reference app, which can act as a controller, these controllers can be run (bring-up) on the same device to commission the DUT.

• In a RPI, Connectedhomeip folder, we have Chip-tool, All-clusters-app, lock-app, light-app etc, if these apps can act as a controller, this can send a subscribe message from the same device to the DUT.

• Our Raspberrypi device [All-cluster-app] does not have an provision to handle this test case.Hence we request for an reference app.

Test case ref:
https://github.com/CHIP-Specifications/chip-test-plans/blob/master/src/securechannel.adoc#tc-sc-3-6-case-resource-validation

• When the device is acting as controller, we will need to shell access (like chip-tool interact shell) so that we can issue commands/subscribe to the DUT that the controller is going to control

Cert Blocker Review: @cjandhyala to follow up with @vivien-apple for possibly how to implement this using the tools we have today.

We already stated elsewhere that a bespoke manner to use a "DUT as a controller" does not go in the spirit of what is required, and actually what we need is just to have N chip-tool clients concurrently, or N python clients concurrently.

There is no arbitrary control path that we could build in less time than using proper means either with chip-tool or Python.

@mrjerryjohns for color about multiple controllers per instance

Cert Blocker Review: Marking this as 'needs provisional' unless we have a resolution to this issue today.

Hi @tcarmelveilleux @mrjerryjohns , Could you share the progress on getting the python script to test TC-SC-3.6? The same solution could be used for TC-RR-1.1 and a test step in TC-IDM-4.2 (which also requires having a controller on the same fabric).

[tcarmelveilleux]

I am making extremely good progress on TC-RR-1.1.

I will attempt to start TC-SC-3.6 today.

SDK Review: We are not taking SDK changes at this point for this test case. Closing, as we believe this is already resolved in master.
