## Key Findings Summary

### Video Recording
- **Configuration:** `record_video_dir` parameter at context creation
- **Video Format:** WebM with VP9 codec (default 800x800)
- **Critical Point:** Videos only accessible after `context.close()`
- **Best Practice:** Implement retention policies (retain-on-failure)

### Screenshot Capture
- **Modes:** Full-page, viewport, element-specific, clipped
- **Wait Strategies:** Use async `wait_for_timeout()`, NOT `time.sleep()`
- **Visual Regression:** Implement checksum-based comparison
- **Format:** PNG (default) or JPEG with quality control

### Trace Files
- **Content:** Screenshots, DOM snapshots, network logs, source code
- **Recording:** `context.tracing.start()` with screenshots/snapshots/sources
- **Chunking:** Use `start_chunk()`/`stop_chunk()` for long tests
- **Viewing:** CLI (`playwright show-trace`) or web (trace.playwright.dev)

### Async API
- **Context Manager:** Always use `async with async_playwright()`
- **Close Order:** Context before browser (`await context.close()` first)
- **Wait Strategies:** Use `await page.wait_for_timeout()`, not `time.sleep()`
- **Windows:** Requires `ProactorEventLoop` configuration

### pytest Integration
- **Fixtures:** page, context, browser, browser_type (built-in)
- **Configuration:** pytest.ini or pyproject.toml
- **Customization:** browser_context_args, browser_type_launch_args
- **Options:** --video, --trace, --screenshot, --headed

### Headless vs Headed
- **CI/CD:** Headless (20-30% faster, fewer resources)
- **Local Development:** Headed with slowdown for debugging
- **Performance:** Headless ~800ms vs Headed ~1000ms per test
- **Debugging:** Use PWDEBUG=1 for interactive inspector

## FAQ

### Q: Which document should I start with?
**A:** If starting fresh → Implementation Guide (Step-by-step setup)
If learning concepts → Research document (Comprehensive theory)
If need code snippets → Quick Reference (Copy-paste ready)

### Q: Do I need async or sync API?
**A:**
- **Sync:** Single test, simple flows, easier for beginners
- **Async:** Parallel tests, CI/CD pipelines, performance-critical
- Recommendation: Sync for development, async for CI/CD

### Q: How do I debug failing tests?
**A:** 1. Run with `--video retain-on-failure`
2. Review video in slow motion
3. Use `PWDEBUG=1` for interactive debugging
4. Check trace files with trace.playwright.dev
5. Review screenshots at key decision points

### Q: What's the performance impact of recording?
**A:**
- Videos: ~15-20% slower (background encoding)
- Screenshots: ~5-10% slower (I/O operations)
- Traces: ~10-15% overhead (DOM snapshots)
- Headless: ~20-30% faster than headed mode

### Q: How do I integrate with CI/CD?
**A:** See PLAYWRIGHT_PYTHON_IMPLEMENTATION_GUIDE.md → "CI/CD Pipeline Integration"
Includes GitHub Actions example and best practices

### Q: Can I run tests in parallel?
**A:** Yes! Use `pytest -n 4` (requires pytest-xdist)
Configure with `--dist loadscope` for test isolation
