From 74772280e698918dbf82477482002ff2eb241223 Mon Sep 17 00:00:00 2001 From: Jeffrey Phillips Freeman Date: Sun, 1 Mar 2026 21:14:23 +0000 Subject: [PATCH 1/5] perf(tests): optimize coverage instrumentation and reporting pipeline Replace coverage.py (sys.settrace-based) with slipcover (bytecode-based instrumentation) for significantly faster coverage collection: - Each behave-parallel worker runs under slipcover, producing per-feature JSON coverage files with unique UUIDs to avoid write contention. - After all workers finish, slipcover --merge combines per-worker data into a single build/coverage.json report. - XML report generated via slipcover --merge --xml for CI tooling. - Terminal report with --fail-under=97 threshold enforcement. - Robust JSON key-fallback logic handles both slipcover and coverage.py output formats. - CI workflow (ci.yml, nightly-quality.yml) updated with defensive key lookup instead of hardcoded coverage.py format. - Documentation updated to reflect slipcover as the coverage tool. - CHANGELOG.md updated.

Save originals as time._original_sleep and asyncio._original_sleep for tests that need real wall-clock delays (CircuitBreaker recovery, debounce timers, validation timeouts). Enhance template-DB patch: add "db." prefix to _SCENARIO_DB_PREFIXES and check db_path.stat().st_size > 0 so 0-byte auto-created SQLite files receive the template copy instead of falling through to real migrations. Replace subprocess.run CLI invocations with typer.testing.CliRunner in module_coverage, main_coverage_complete, and coverage_extras step files, eliminating ~6s Python cold-start overhead per call. Switch plan_persistence and action_persistence to in-memory SQLite by default; only cross-restart scenarios use file-based via an explicit Given step. Replace MigrationRunner.run_migrations with Base.metadata.create_all in plan_service_steps for freshly created in-memory engines. Removed leftover debug comment in environment.py. Total tier runtime: 565s -> 21s (96% reduction), 20 features all under 5s behave-internal time.

Sequential mode (--processes 1 or BEHAVE_PARALLEL_COVERAGE=1): All features run in a single Runner.run() call. Steps and hooks load once. Parallel mode (--processes N, N>1): Features split into N chunks, dispatched via multiprocessing.Pool with fork. Heavy modules shared copy-on-write. Proper format defaulting (mirrors behave.__main__.run_behave() logic for -q flag). Summary extracted from runner.features status attributes instead of regex-parsing stdout. Simplified coverage pipeline: single slipcover invocation wraps the entire behave-parallel process. No per-worker UUID files, no --merge step needed. Coverage data produced in one build/coverage.json file. Removed: behave-parallel tarball download from PyPI, tarfile and urllib.request imports, per-worker subprocess.run() calls, __SLIPCOVER_OUT__ placeholder mechanism, _build_base_args(), _parse_summary(), regex-based summary parsing. Results: nox -s unit_tests 24m21s -> 2m05s (91%); nox -s coverage_report 75m20s -> 3m00s (96%). Coverage: 98% (above 97% threshold).

Sequential mode runs all + features in a single `Runner.run()` call; parallel mode uses `multiprocessing.Pool` with + `fork` for COW sharing of heavy modules.

(#481) - Optimized 20 medium-slow BDD features (10-100s tier). Capped `time.sleep` and `asyncio.sleep` globally at 10ms in `before_all` to eliminate retry/backoff waits; originals saved as `time._original_sleep` / `asyncio._original_sleep` for timing-sensitive tests.
