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 introduces a new test case to verify the gNSI accounting functionality on a device under test (DUT) when authentication fails. It ensures that the device correctly generates and reports accounting records for various gRPC services under different failure conditions, such as incorrect credentials or invalid TLS certificates. The implementation leverages the existing featureprofiles test framework to perform these validations in a systematic and automated manner.

Highlights

• New Test Implementation: Added a comprehensive test suite for ACCTZ-8.1 to validate gNSI accounting records during authentication failure scenarios.
• Table-Driven Testing: Implemented a robust table-driven testing approach covering multiple gRPC services (gNMI, gNOI, gNSI, gRIBI, P4RT) and various credential failure scenarios.
• In-Memory Certificate Generation: Added utility functions to generate self-signed TLS client certificates in-memory to simulate authentication failures without requiring external files.

Code Review

This pull request introduces the AccountingAuthenFailUni test, which validates gNSI accounting for authentication failures across gNMI, gNOI, gNSI, gRIBI, and P4RT services. The test simulates various failure scenarios, such as incorrect passwords and invalid certificates, and verifies the accuracy of the generated accounting records. The review feedback recommends using the correct streaming client for gNSI and removing redundant timer logic in the record collection helper.
