Summary of Changes

Hello @arekay-nv, 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 enhancing the stability and clarity of the benchmarking framework. It ensures that test sessions in the load generator gracefully handle exceptions and always complete their shutdown procedures, preventing orphaned processes or incorrect state. Additionally, it refines the import practices within the test suite to prevent naming conflicts, contributing to a more robust and maintainable codebase.

Highlights

• Robust Load Generator Shutdown: Implemented a try...except...finally block in the load generator's _run_test method to guarantee that the sample issuer is always shut down and the TEST_ENDED event is recorded, even if an error occurs during the test run. This prevents potential resource leaks or incomplete test state reporting.
• Resolved TestType Naming Conflict in Unit Tests: Addressed a potential naming collision for the TestType enum within unit tests by aliasing its import as BenchmarkTestType. This improves clarity and avoids ambiguity when other TestType definitions might exist in the test environment.

Code Review

This pull request primarily addresses warnings in the test suite by aliasing an imported enum and improves the robustness of the benchmark session runner. The changes in the test files are correct and effectively resolve potential pytest collection warnings. In session.py, the addition of a try...finally block is a good enhancement to ensure proper resource cleanup. I have one suggestion to improve exception handling within this new block to make debugging easier by preserving the full stack trace.

[gemini-code-assist]

Using raise e resets the stack trace to this line, which can hide the original location where the exception was raised. For better debuggability, it's preferable to use a bare raise statement inside an except block. This re-raises the caught exception while preserving its full original traceback.

Suggested change

	raise e
	raise

[nvzhihanj]

@arekay-nv we should probably remove the branch name validator because they don't seem to matter. For the auto request review let's fix it because it will be useful in the future.

For the perf tests that are failing - maybe we need a more capable runner?
