# Phase 7 — Validation Strategy
> Per-phase validation contract for feedback sampling during execution.
---
## Test Infrastructure
| Property | Value |
|----------|-------|
| **Framework** | Vitest 4.1.9 (apps/web); no test framework in apps/api |
| **Config file** | `apps/web/vitest.config.ts` |
| **Quick run command** | `pnpm --filter @tessera/web test` |
| **Full suite command** | `pnpm --filter @tessera/web test && pnpm --filter @tessera/api type-check` |
| **Estimated runtime** | ~30 seconds |
---
## Sampling Rate
- **After every task commit:** Run `pnpm --filter @tessera/web test`
- **After every plan wave:** Run `pnpm --filter @tessera/web test && pnpm --filter @tessera/api type-check`
- **Before `/gsd-verify-work`:** Full suite must be green + manual PDF parse inspection + manual Excel file inspection
- **Max feedback latency:** ~30 seconds

## Per-Task Verification Map
| Task ID | Plan | Wave | Requirement | Threat Ref | Secure Behavior | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|------------|-----------------|-----------|-------------------|-------------|--------|
| 07-01-01 | 01 | 0 | DKV-02 | A2 | PDF parse output inspected manually | Manual | — | ❌ Wave 0 | ⬜ pending |
| 07-01-02 | 01 | 0 | — | — | ScheduleModule registered in AppModule | Manual type-check | `pnpm --filter @tessera/api type-check` | ✅ | ⬜ pending |
| 07-02-01 | 02 | 1 | DKV-01 | — | Inbox polling returns attachments | Manual integration | — | ❌ Wave 0 | ⬜ pending |
| 07-02-02 | 02 | 1 | DKV-04 | — | Excel 5-column buffer generated | Manual (open .xlsx) | — | — | ⬜ pending |
| 07-03-01 | 03 | 1 | DKV-03 | — | Vehicle CRUD table renders | unit | `pnpm --filter @tessera/web test` | ❌ Wave 0 | ⬜ pending |
| 07-03-02 | 03 | 1 | DKV-05 | — | SMTP settings form saves + reads | unit | `pnpm --filter @tessera/web test` | ❌ Wave 0 | ⬜ pending |
*Status: ⬜ pending · ✅ green · ❌ red · ⚠️ flaky*

## Wave 0 Requirements
- [ ] `apps/api/src/dkv/dkv-parser.validate.ts` — manual validation script: parse `user-files/invoice.pdf`, print structured output, verify vehicle block regex
- [ ] `apps/web/src/app/(portal)/modules/dkv-fleet/settings/components/VehicleTable.test.tsx` — covers DKV-03 (vehicle CRUD table)
- [ ] `apps/web/src/app/(portal)/settings/general/smtp/smtp-settings.test.tsx` — covers DKV-05 (SMTP settings form)
---
## Manual-Only Verifications
| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Inbox polling detects DKV emails | DKV-01 | Requires live IMAP/Exchange inbox | Configure module with test inbox, trigger "Jetzt prüfen", verify email detected and PDF downloaded |
| PDF parser extracts correct data | DKV-02 | No API test framework; PDF content is binary | Run Wave 0 validation script against `user-files/invoice.pdf`; inspect 27 vehicles × transactions in output |
| Excel export correct format | DKV-04 | Requires human visual inspection in Excel | Open generated `.xlsx`, verify 5 columns (Lieferdatum, Fahrzeug, Fahrer, Ort, Kilometerstand), German date format `TT.MM.JJJJ` |
| SMTP delivery | DKV-04 | Requires live SMTP server | Trigger export with test SMTP config, verify email received with xlsx attachment |
---
## 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
- [ ] `nyquist_compliant: true` set in frontmatter
**Approval:** pending
