# Phase 2 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | pytest 8.x |
| **Config file** | pytest.ini |
| **Quick run command** | `pytest tests/test_pipeline/test_link_parser.py tests/test_platforms/ -x -v` |
| **Full suite command** | `pytest tests/ -v --cov=kb_pipeline` |
| **Estimated runtime** | ~15 seconds |

---

## Sampling Rate

- **After every task commit:** Run `pytest tests/test_pipeline/test_link_parser.py tests/test_platforms/ -x`
- **After every plan wave:** Run `pytest tests/ -v --cov=kb_pipeline`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 15 seconds

## Wave 0 Requirements

- [ ] `tests/test_pipeline/test_link_parser.py` — LinkParser 单元测试
- [ ] `tests/test_pipeline/test_idempotency.py` — 幂等检查测试
- [ ] `tests/test_platforms/__init__.py` — 测试模块初始化
- [ ] `tests/test_platforms/conftest.py` — 平台测试共享 fixtures
- [ ] `tests/test_platforms/test_bilibili.py` — B站适配器测试
- [ ] `tests/test_platforms/test_zhihu.py` — 知乎适配器测试
- [ ] Mock fixtures: B站/知乎 API 响应数据

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| 短链解析 (b23.tv) | PLAT-01 | 需要真实网络请求 | 提供真实 b23.tv 短链，验证解析到正确 URL |
| Cookie 过期检测 | PLAT-03 | 需要过期 Cookie | 使用过期 Cookie 访问知乎，验证错误提示 |

---

## 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 < 15s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
