Testing and evidence

Every number in the docs can be reproduced, and every behaviour that matters has a test.

The suites (tests/)

File	What it proves
test_core.py	discovery filters, board harvesting, fit gate, tailoring and validation, answer rules, option picking
test_v08.py	scheduler (overlap, preemption, failure isolation, quantum maths), drafts (only open questions, only Fact Bank text, honest closings), event log (3 processes × 200 large lines never tear; incremental, tolerant reads), the long-term sponsorship rule and its airbag, no control characters in the rules, experience and "select all" answers, code matching
test_api.py	every API endpoint over a seeded log; the answer write path is off by default, localhost only, refuses legal/EEO/sensitive questions, replaces instead of duplicating, re-queues the job
test_forms.py	the real filler in headless Chromium against local look-alikes of Greenhouse, Ashby and Lever: drafted "why" answer from the Fact Bank, sponsorship from presets, EEO declined, CSS-only required field caught, follow-up questions, proof screenshot on disk, dry runs never submit

Tests use a fictional persona (tests/fixtures/presets.json, profile.example/) and a throwaway workspace; they never read real data. The form tests intercept requests to the ATS hosts and answer with the fixture page, so nothing leaves the machine.

Coverage

python -m pytest -q --cov=engine --cov=apps/api --cov-report=term-missing

CI runs the same command on every pull request (the form tests are skipped there if Chromium isn't installed).

Benchmarks

Script	Claim it checks
scripts/bench_scheduler.py [jobs] [tabs] [seed]	round-robin speed-up and browser utilization (deterministic clock)
scripts/bench_tailor.py <old tailor.py>	the new tailoring returns identical output on every saved JD, and how much faster

Evidence in production

• python -m engine report: only submissions whose proof screenshot exists.
• schedule events: real wall time, active time and switches for each run.
• workspace/drafts_review.md: every drafted answer with its fact ids.
