Summary of Changes

Hello @toby-coleman, 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 improving the stability of the tuner integration tests. It introduces tolerance to the assertions that verify the optimal results found by the tuner, which should mitigate intermittent CI failures caused by slight variations in test outcomes. Additionally, it slightly adjusts the search space for one of the hyperparameters in the test.

Highlights

• Test Stability: Modified the test_tune integration test to incorporate tolerance into assertions for the best found hyperparameter values, specifically for a.iters and c.in_1. This change aims to address intermittent failures in CI by allowing a small range of acceptable optimal results rather than strict equality.
• Test Parameter Range Adjustment: Increased the upper bound of the iters hyperparameter search space from 8 to 9 within the test_tune function's configuration, potentially expanding the range of values the tuner explores.

Code Review

This pull request addresses intermittent test failures in the tuner by adding tolerance to the assertions. The changes are logical and correctly implement the intended tolerance. The refactoring of the metric assertion to be dynamic is a good improvement. I've added one comment regarding the hardcoded values in the assertions, suggesting a way to make the test more maintainable and robust against future changes to the parameter search space.
