# Phase 1 — Validation Strategy
|
|
|
|
> Per-phase validation contract for feedback sampling during execution.
|

## Test Infrastructure
|
|
|
|
| Property | Value |
|
|
|----------|-------|
|
|
| **Framework** | pytest >=8 |
|
|
| **Config file** | **None in Wave 0** — Wave 0 adds tests and dev deps only; no `pytest.ini` / `pyproject` `[tool.pytest]` block is required until markers grow. |
|
|
| **Quick run command** | `python -m pytest tests/unit/data/test_tradier.py -x -q` |
|
|
| **Full suite command** | `python -m pytest tests/ -q` |
|
|
| **Estimated runtime** | ~5 seconds |
|
|
|
|
**Tier / replay:** `tests/unit/data/test_tradier.py` is **Tier 2 (data layer)**. Use **vcrpy** (or pytest-vcr) to record/replay Tradier HTTP into `tests/fixtures/cassettes/tradier/` (or `tests/unit/data/cassettes/`).
|

|
|
## Sampling Rate
|
|
|
|
- **After every task commit:** Run `python -m pytest tests/unit/data/test_tradier.py -x -q`
|
|
- **After every plan wave:** Run `python -m pytest tests/ -q`
|
|
- **Before `/gsd:verify-work`:** Full suite must be green
|
|
- **Max feedback latency:** 5 seconds
|

## Per-Task Verification Map
|
|
|
|
| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|
|
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
|
|
| TBD | TBD | TBD | DATA-01 | unit | `python -m pytest tests/unit/data/test_tradier.py -k chain -q` | ❌ W0 | ⬜ pending |
|
|
| TBD | TBD | TBD | DATA-02 | unit | `python -m pytest tests/unit/data/test_tradier.py -k expirations -q` | ❌ W0 | ⬜ pending |
|
|
| TBD | TBD | TBD | DATA-03 | unit | `python -m pytest tests/unit/data/test_tradier.py -k greeks -q` | ❌ W0 | ⬜ pending |
|
|
| TBD | TBD | TBD | DATA-04 | unit | `python -m pytest tests/unit/data/test_tradier.py -k iv -q` | ❌ W0 | ⬜ pending |
|
|
| TBD | TBD | TBD | DATA-05 | unit | `python -m pytest tests/unit/data/test_tradier.py -k dte -q` | ❌ W0 | ⬜ pending |
|
|
| TBD | TBD | TBD | DATA-08 | integration | `python -m pytest tests/unit/data/test_tradier.py -k vendor -q` | ❌ W0 | ⬜ pending |
|
|
|
|
**DATA-06 / DATA-07:** Intentionally omitted here — validated in **Phase 2** (DATA-06) and **Phase 10** (DATA-07); see `.planning/REQUIREMENTS.md` traceability.
|
|
|
|
*Status: ⬜ pending · ✅ green · ❌ red · ⚠️ flaky*

## Wave 0 Requirements
|
|
|
|
- [ ] `tests/unit/data/test_tradier.py` — stubs/tests for DATA-01 through DATA-05 and DATA-08
|
|
- [ ] `tests/conftest.py` — shared fixtures; **vcrpy** cassette config for Tradier HTTP replay
|
|
- [ ] pytest + vcrpy dev install — `uv add --dev pytest>=8.0 vcrpy` (or equivalent)
|
|
|
|
*Aligned with the **Config file** row: Wave 0 does not add a pytest config file unless needed later.*

## Manual-Only Verifications
|
|
|
|
| Behavior | Requirement | Why Manual | Test Instructions |
|
|
|----------|-------------|------------|-------------------|
|
|
| Production Greeks accuracy | DATA-03 | Sandbox returns no Greeks; production API key required | Call chain for AAPL, verify delta/gamma/theta/vega/rho are non-null floats |
|
|

|
## Validation Sign-Off
|
|
|
|
- [ ] Every task has an **Automated Command** entry in the map above **or** an explicit Wave 0 dependency (no bare `<automated>` placeholders)
|
|
- [ ] Sampling continuity: no 3 consecutive tasks without automated verify
|
|
- [ ] Wave 0 covers all MISSING references
|
|
- [ ] No watch-mode flags
|
|
- [ ] Feedback latency < 5s
|
|
- [ ] `nyquist_compliant: true` set in frontmatter
|
|
|
|
**Approval:** pending
