[Bug] test-dcl-server.py Missing in Test Harness(Version: v2.12-beta2+spring2025 Sha: 41b4745) for TC-CGEN-2.12 Validation

[Rajashreekalmane]

Describe the bug

The test-dcl-server.py file is missing in the Test Harness, preventing the validation of the TC-CGEN-2.12 test case. This script is required for execution.
https://github.com/project-chip/connectedhomeip/blob/master/examples/chip-tool/commands/dcl/test_dcl_server.py

Environment

Version: v2.12-beta2+spring2025
Sha: 41b4745

Hi @Rajashreekalmane,

I couldn't find any TC-CGEN-2.12 test available in the repos.
Can you point me out where is this test? Was it a typo?

Let me know and please share any information about this test-dcl-server.py script.

[Rajashreekalmane]

@antonio-amjr The TC-CGEN-2.12 test case is not automated, so it won’t be available in the Python testing directory or YAML repo. This test case needs to be validated manually.

Here are the relevant references for validation:

Test Plan: TC-CGEN-2.12
Validation Instructions: GitHub PR #37049

Let me know if you need any further details.

@Rajashreekalmane,

That helps. I'll take a look.
I already managed to copy the test-dcl-server.py on a chip-cert-bins image test locally.
We will confirm if we should create another SDK image and when.

Let me see if I handle verifying the script and TC-CGEN-2.12 with those links you shared.
I'll be back soon.

Hey @Rajashreekalmane,

Sharing more about this issue. Executing the test-dcl-server.py, I noticed the following error:

It seems that the script presents this error when using python3.
There's already a draft PR#37549 on the SDK side that solves it (tested locally) and should enter so it may work properly.

I'll see with the team what approach we should do in this case.

[Rajashreekalmane]

Thanks, @antonio-amjr, That sounds good. I'll wait for your confirmation on whether a new SDK image is needed. I noticed that v2.12-beta3+spring2025 was recently released—do you know if the fix is included in this version?

[antonio-amjr]

No, the v2.12-beta3+spring2025 does not have the fix. I don't have any updates on that either.
Since the PR#37549 is still a draft and I don't know when it'll be ready, so even adding the script to the apps/ it'll still have this error I mentioned above.

[antonio-amjr]

The PR#37549 was merged on the master branch of SDK.
