Human review is resolved; exact-head CI is running.

Change

  • Sample only tests whose complete YAML mapping set is wired to live Jenkins stages.
  • Exhaustively require every live-stage-backed test to resolve.
  • Keep sampled stage-validity and YAML-reference checks without duplicating the exhaustive nonempty assertion.

Validation

No API, dependency, ownership, or documentation changes apply.

Walkthrough

The test suite now selects tests connected only to live Jenkins stages, uses deterministic local sampling, validates stage mappings, and runs bidirectional and round-trip consistency checks.

Changes

Mapping consistency validation

Layer / File(s) Summary
Validate stage-backed test selection
tests/unittest/tools/test_test_to_stage_mapping.py
Filters YAML-backed tests by live Jenkins stage mappings. Uses typed inputs and deterministic local random generators. Adds targeted validation for missing or unwired mappings.
Enable mapping consistency validation
tests/unittest/tools/test_test_to_stage_mapping.py
Removes the skip marker so bidirectional and round-trip mapping checks execute.

Estimated code review effort: 2 (Simple) | ~10 minutes

Mergeability Score: ⚪ Minimal · up to a1c0e

This localized test change scopes mapping checks to live stages and reports successful validation; no actionable merge-blocking risk remains after normal checks and review.

sample_test_cases, and test_all_stage_backed_tests_map: annotate StageQuery
fixture parameters, use list[str] for list-returning functions, and use None for
the test procedure.
- Around line 28-37: Sort the list returned by _stage_backed_tests before any
sampling occurs, and update both sampling fixtures to use a local
random.Random(0) instance instead of random.seed(0), preserving deterministic
selections without modifying the process-wide generator.
- Around line 93-105: Validate the updated mapping tests, including
test_all_stage_backed_tests_map and test_bidirectional_mapping_consistency, and
report the test outcome; no production-code changes or additional QA entry are
needed.

Approving — the comments below are optional touch-ups, not blockers.

Verified locally against this head: 1810 tests in the DB, 1748 stage-backed, 0 unmapped — the numbers in the description hold, and the exhaustive check is a stronger gate than the sampled one it replaces, so removing the waiver is justified rather than just re-skipping around the failure.

Two follow-ups outside the diff hunks that this change strands:

  • test_cli_functionality (line 260-266) still hunts for "the first sample that maps to at least one stage" and skips if none do, with a comment blaming multi-node perf-sanity lists. Those lists are exactly what the new fixture filters out, so the fallback is now unreachable and the comment is misleading. Use sample_test_cases[0] directly and drop the comment.
  • Same for the roundtrip branch at line 312 (if not stages: continue) — silently skipping is now impossible; if you keep it, it hides a regression rather than tolerating a known gap.

Both are cheap to fix in this PR and keep the file honest about what the fixture guarantees.
