# Phase 9 — Validation Strategy

> Per-phase validation contract for feedback sampling during execution.

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | pytest >= 8.0 (+ pytest-playwright for e2e) |
| **Config file** | none — pytest discovers `tests/` by default |
| **Quick run command** | `pytest tests/ -x -q --ignore=tests/e2e` |
| **Full suite command** | `pytest tests/ -v` |
| **E2E command** | `pytest tests/e2e/ -v` (requires `playwright install chromium`) |
| **Estimated runtime** | ~20s unit/integration, ~15s e2e |

---

## Sampling Rate

- **After every task commit:** Run `pytest tests/ -x -q --ignore=tests/e2e`
- **After every plan wave:** Run `pytest tests/ -v`
- **Before `/gsd:verify-work`:** Full suite (including `tests/e2e/`) must be green
- **Max feedback latency:** 30 seconds

## Wave 0 Requirements

- [ ] `tests/test_driver_upload.py` — add stubs: `test_upload_500_regression`, `test_upload_returns_oob_when_called_from_form`, `test_upload_oob_autoselects_new_driver` (UX-01)
- [ ] `tests/e2e/__init__.py` + `tests/e2e/conftest.py` — live server fixture (uvicorn thread on 127.0.0.1, readiness poll via `/health`, session-scoped tmp data dir) (UX-02)
- [ ] `tests/e2e/test_port_autofill.py` — stub Playwright test for UX-02
- [ ] `tests/test_script_download.py` — stubs for `.ps1` URL shape routes (UX-03)
- [ ] `tests/test_packages.py::TestCommandPreview::test_detail_page_shows_script_links` — stub (UX-03)
- [ ] Dev deps install: add `pytest-playwright` and `playwright` to `requirements-dev.txt`; run `pip install -r requirements-dev.txt && playwright install chromium`

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Live browser visual confirmation of IP→port auto-fill | UX-02 | Success criterion explicitly requires "observed live in a real browser and recorded in VALIDATION.md" | Run `pytest tests/e2e/test_port_autofill.py -v --headed`, observe the browser window, save terminal output snippet here when executed |
| Live browser visual confirmation of driver upload OOB refresh | UX-01 | Success criterion explicitly requires "without manually reloading the page" — Playwright headless covers this, but a live eyeball check is recommended once | Start app, open printer form, upload driver ZIP, confirm dropdown updates without F5 |
| Live browser click of 3 script download links | UX-03 | Success criterion says "can click direct download links ... individually" | Start app, open printer detail page with a driver selected, click each of the 3 links, confirm `.ps1` file downloads |

*Automated coverage is primary; manual checks serve as the live-verification evidence required by the phase success criteria.*

## Validation Sign-Off

- [ ] All tasks have `<automated>` verify or Wave 0 dependencies
- [ ] Sampling continuity: no 3 consecutive tasks without automated verify
- [ ] Wave 0 covers all MISSING references
- [ ] No watch-mode flags
- [ ] Feedback latency < 30s (quick suite)
- [ ] `nyquist_compliant: true` set in frontmatter (after planner finalizes task IDs)

**Approval:** pending
