Summary of Changes

Hello @raul-marquez-csa, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on updating and clarifying the TC-DD-1.1 test script, which is responsible for verifying QR code onboarding payloads. The primary goal is to align the script with the most recent test plan specifications, ensuring that it provides more detailed instructions, explicit verification criteria, and improved logging. These changes collectively aim to create a more robust, transparent, and up-to-date testing process for Matter device onboarding.

Highlights

• Test Script Description Update: The test script description for TC-DD-1.1 has been updated to refer to the 'Matter network' instead of the 'CHIP network', reflecting the latest branding.
• Detailed Test Steps and Verification Criteria: The create_test_steps method has been significantly revised to include detailed verification criteria and expectations directly within each test step description, making the test plan clearer and more comprehensive.
• Enhanced Logging and Execution Flow: New logger.info messages have been added before each verification check in the execute method, providing better visibility into the script's progress. The order of checks has also been adjusted to align with the updated test steps.
• New Verification Checks: New verification steps have been introduced for the Custom Flow bit and 8-bit Discovery Capabilities bit mask. A placeholder for verifying the packed binary data structure has also been added, though it is currently marked as a TODO.

Code Review

This pull request updates the TC-DD-1.1 test script to align with the latest test plan by adding more detailed instructions and logging. While the changes are a good improvement in terms of clarity and alignment with the test plan, I've found a critical syntax error in one of the new test step definitions and a high-severity logic error in how the test steps are advanced, which would cause incorrect test execution and reporting. Please address these issues.

In the TC-DD-1.1 test plan

there's an extra step at the end, step 3.

Step3  |  Verify the packed binary data structure  |  Verify the packed binary data structure is padded with '0' bits at the end of the structure to the nearest byte boundary.

This step isn't currently implemented in the script. Please advise on how to implement this step, or, if the script is the source of truth, then to remove the step from the test plan.
