Pull Request Overview

This PR adds a new Python test script for the ClosureControl cluster (TC-CLCTRL-2.1) that verifies proper attribute reading and range validations. Key changes include:

• Implementation of test steps covering commissioning, attribute list reading, and attribute value validations.
• Detailed checks for attributes such as CountdownTime, MainState, CurrentErrorList, OverallState, and OverallTarget.
• Logging and assertions to ensure the attribute values are within expected ranges.

• Consider adding a test case to cover the scenario where overall_state is None so that the behavior of the else branch is verified.

            logging.info("OverallState is NULL, skipping steps")

src/python_testing/TC_CLCTRL_2_1.py:163

• Consider adding a test case to validate the branch handling when overall_target is None to ensure comprehensive test coverage.

            logging.info("OverallTarget is NULL, skipping steps")

This test script will be validated once the app is finished and added to the CI at the same time.

The test plan, for steps 6 and 7, use the featuremap PICS as the way to determine if a check should be done or not.

The test plan uses the feature map configured on the device to this instead. Both ways are acceptable, but we nee dto make sure the test plan matchs the script implementation.
