# Phase 15 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | pytest 7.x |
| **Config file** | `pyproject.toml` |
| **Quick run command** | `pytest tests/test_printer_form.py tests/test_driver_upload.py -x -q` |
| **Full suite command** | `pytest tests/ -x -q --ignore=tests/e2e` |
| **Estimated runtime** | ~10 seconds |

---

## Sampling Rate

- **After every task commit:** Run `pytest tests/test_printer_form.py tests/test_driver_upload.py -x -q`
- **After every plan wave:** Run `pytest tests/ -x -q --ignore=tests/e2e`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 10 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 15-01-01 | 01 | 1 | UX-01 | integration | `pytest tests/test_printer_form.py::test_printers_new_driver_list_visible -x -q` | ❌ W0 | ⬜ pending |
| 15-01-02 | 01 | 1 | UX-01 | integration | `pytest tests/test_printer_form.py::test_upload_feedback_visible_on_printers_new -x -q` | ❌ W0 | ⬜ pending |
| 15-01-03 | 01 | 1 | UX-01 | regression | `pytest tests/test_driver_upload.py::test_upload_returns_oob_when_called_from_form -x -q` | ✅ | ⬜ pending |

*Status: ⬜ pending · ✅ green · ❌ red · ⚠️ flaky*

---

## Wave 0 Requirements

- [ ] `tests/test_printer_form.py` — add `test_printers_new_driver_list_visible` (asserts no `style="display:none"` on `#driver-list` in GET /printers/new response)
- [ ] `tests/test_printer_form.py` — add `test_upload_feedback_visible_on_printers_new` (asserts driver name appears in upload response fragment when caller="printer_form")

*Existing test infrastructure (pytest, conftest, fixtures) already in place — only these two new assertions are missing.*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Upload feedback visually readable on /printers/new in browser | UX-01 | Visual confirmation | 1. Open /printers/new in browser 2. Upload a driver ZIP 3. Confirm driver name + confirmation appears on page |

---

## 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 < 10s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
