feat: pre-PR local test runner gate (Closes #580) - #597
Merged
Conversation
Implement a targeted test shard runner that maps changed source files
to their most relevant test counterparts BEFORE gh pr create. This
shifts validation left — catches regressions locally instead of
waiting for CI minutes later.
Four-tier mapping heuristic:
1. Exact match: agent/foo.py → tests/agent/test_foo.py
2. Module match: built into the exact-match lookup by basename
3. Directory fallback: hermes_cli/config.py → tests/hermes_cli/
4. Last resort: pytest tests/ -x -q --timeout=120 -k 'not slow and not docker'
Files:
- scripts/evolution_pre_pr_test_runner.py — the gate script (541 lines)
- tests/scripts/test_evolution_pre_pr_test_runner.py — 30 pure tests
- skills/evolution/evolution-implementation/SKILL.md — integrated as
Step 1 in the 'Validate LOCALLY' section of the PR-creation flow
The script is standalone + import-safe: pure functions are injectable
for offline testing. Logs go to
~/.hermes/profiles/user1/evolution/pre-pr-test-results/{timestamp}.log.

Automated evolution PR for issue #580. Adds evolution_pre_pr_test_runner.py — a targeted test shard gate that identifies and runs the most relevant tests before PR creation, shifting validation left and reducing CI failure rate.
