Summary of Changes

Hello, 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 enhances the reliability of the DSCP transparency tests by introducing explicit wait conditions for ATE metrics. By ensuring that all tagged metrics are present before validation logic executes, the changes reduce flakiness caused by asynchronous data population in the test environment.

Highlights

  • Test Stability Improvements: Added polling loops to verify that all ATE tagged metrics are populated before proceeding with flow validation, preventing race conditions.
  • Timeout Handling: Implemented a 45-second timeout mechanism for metric population, ensuring the test fails gracefully if the ATE does not report the expected data.

Code Review

This pull request introduces manual wait loops using time.Sleep in three test functions to ensure tagged metrics are populated before validation. Feedback indicates that these loops violate the repository style guide, which mandates using gnmi.Watch with .Await instead of time.Sleep. The reviewer also recommended refactoring the duplicated logic into a reusable helper function and optimizing the gNMI lookups to improve efficiency and maintainability.
