Metadata

  • Commit message: fix(nox): run asv machine --yes before benchmarks
  • Branch: main

Background and Context

The test fix(nox): run asv machine --yes before benchmarks has been observed to be flaky, with intermittent failures and successes across CI runs.

Description

The test fix(nox): run asv machine --yes before benchmarks has been observed to be flaky, with intermittent failures and successes.

Run History

Suspected Cause

The flakiness of this test may be due to a race condition or a dependency on an external service that is not always available. Further investigation is needed to determine the exact cause.

Duplicate Check

Expected Behavior

The test fix(nox): run asv machine --yes before benchmarks should pass consistently on every CI run without intermittent failures. The asv machine --yes step should reliably complete before benchmarks are executed, regardless of environment state or timing.

Acceptance Criteria

  • The root cause of the flakiness is identified and documented.
  • The test passes consistently across a minimum of 10 consecutive CI runs after the fix is applied.
  • No race conditions or external service dependencies remain unguarded in the nox benchmark session.
  • If the cause is an external dependency, appropriate retry logic or mocking is introduced.
  • CI run history shows no further intermittent failures for this test after the fix.

Subtasks

  • Reproduce the failure locally or in CI to confirm the flaky behaviour.
  • Analyse the nox benchmark session configuration and the asv machine --yes invocation for timing issues or missing guards.
  • Investigate whether the failure is environment-specific (e.g., missing machine config file, network dependency, file-system race).
  • Implement a fix (e.g., retry logic, explicit wait, environment pre-check, or test isolation).
  • Add or update tests to prevent regression.
  • Verify the fix by monitoring CI runs until the test is stable.

Definition of Done

This issue should be closed when:

  1. The root cause of the flakiness has been identified and documented.
  2. A fix has been implemented, reviewed, and merged.
  3. The test passes consistently across at least 10 consecutive CI runs with no intermittent failures.
  4. Test coverage remains ≥ 97%.
