Test Case

TC-TMP-2.1

Reproduction steps

1. Execute the below mentioned command to put DUT into a commissionable state : ./chip-all-clusters-app
2. Once DUT reach the commissionable state sent Python run command on TH : python3 TC_TMP_2_1.py --commissioning-method on-network --discriminator 3840 --passcode 20202021 --storage-path admin_storage.json --paa-trust-store-path ../../credentials/development/paa-root-certs/

Anything else?

I tried to execute the TC-TMP-2.1 Python test, but the test case is failing at Test Step 3 (TH reads the MinMeasuredValue attribute from the DUT and saves as min_measured_value. If min_measured_value is not null, set min_bound to min_measured_value) with below error.

@Ashwinigrl do you know when this test was passing last time ? If you could git bisect and narrow down the commitID it failed, that would be super helpful.

[Ashwinigrl]

This is a newly added script @cjandhyala There are no issues with the SDK, and we can run the test case manually as per the test plan. Even though the script matches the test plan, it fails at the 3rd step during execution.

Why is TH getting back "unsupported cluster" here? That cluster is definitely supported on all-cluster-app....

(Separately, TH seems to not be doing detailed data model logging here, so it's hard to tell what it really got.)

test defaults to EP0, so try with --endpoint 1 (or wherever that cluster is located on the device)

[Ashwinigrl]

Tried with --endpoint 1, Test case is passed. hence closing this Issue.
