feat: Phase 3.6 — integration + acceptance tests for YouTube proxy
- test_integration_phase3.py: 6 tests Extract→proxy flow (VOD manifest, VOD segment, live manifest), cache hit bypasses yt-dlp, upstream 404→502, extract disabled→503 Mocked yt-dlp, real FastAPI TestClient + HLSProxyService - test_acceptance_phase3_youtube.py: 3 tests Real YouTube VOD extraction, manifest proxy, segment proxy Follows master→variant→segment chain, verifies MPEG-TS sync byte - test_acceptance_phase3_live.py: 3 tests Real live stream extraction, no #EXT-X-ENDLIST assertion, cache refresh verification, graceful skip when offline - 201/201 CI pass (234 backend Phase 1-3, zero Phase 3 regressions) - Updated plan: 3.6 Complete, 6/7 sub-phases done

# Phase 3: YouTube Live Stream Proxy → ASR → RAG — Implementation Plan
|

### Phase 3.6 — Integration & Acceptance Testing (1 day)
|
||||
### Phase 3.6 — Integration & Acceptance Testing ✅ Complete
|
||||
|
||||
**Tests:** `test_integration_phase3.py`, `test_acceptance_phase3_youtube.py`, `test_acceptance_phase3_live.py`
|
||||
**Tests:** `test_integration_phase3.py` (6 tests), `test_acceptance_phase3_youtube.py` (3 tests), `test_acceptance_phase3_live.py` (3 tests)
|
||||
|
||||
**Integration test** (`backend/app/test/test_integration_phase3.py`):
|
||||
- `TestExtractAndProxyFlow` — full extract→proxy flow (VOD manifest, VOD segment, live manifest), cache hit verification
|
||||
- `TestProxyAfterExtract` — upstream manifest unavailable after extract → 502
|
||||
- `TestExtractDisabled` — extract returns 503 when `youtube_proxy_enabled=false`
|
||||
- Mocked yt-dlp, real FastAPI TestClient, real HLSProxyService
|
||||
|
||||
**Acceptance test VOD** (`backend/app/test/acceptance/test_acceptance_phase3_youtube.py`):
|
||||
- Real YouTube VOD extraction and proxy verification
|
||||
- Manifest proxy → verify M3U8 structure and CORS
|
||||
- Segment proxy → follow master→variant→segment chain, verify MPEG-TS data
|
||||
- Skips gracefully if `YOUTUBE_TEST_VOD_URL` not set
|
||||
|
||||
**Acceptance test live** (`backend/app/test/acceptance/test_acceptance_phase3_live.py`):
|
||||
- Real YouTube live extraction (is_live=True, combined formats)
|
||||
- Live manifest proxy → verify no #EXT-X-ENDLIST
|
||||
- Cache refresh verification (same video_id on re-extract)
|
||||
- Skips gracefully if `YOUTUBE_TEST_LIVE_URL` not set or stream offline
|
||||
|
||||
**How to run acceptance tests:**
|
||||
```bash
|
||||
cd backend && YOUTUBE_TEST_VOD_URL="https://www.youtube.com/watch?v=5bF3tkO5jAA" \
|
||||
YOUTUBE_TEST_LIVE_URL="https://www.youtube.com/watch?v=fN9uYWCjQaw" \
|
||||
python -m pytest app/test/acceptance/test_acceptance_phase3_youtube.py \
|
||||
app/test/acceptance/test_acceptance_phase3_live.py -v -m acceptance
|
||||
```
|
||||
|
||||
**Tasks:**
|
||||
| # | Task |
|
||||
|---|------|
|
||||
| 3.6.1 | Implement integration test (mocked yt-dlp, real httpx proxy + hls.js) |
