## ⏳ Manual Testing Required

**What needs validation**: User interaction behaviors in browser

### Core Tests (Must Complete)
1. ✓ Visual: Arrow markers render correctly
2. ✓ Interaction: Hover effects work smoothly  
3. ✓ Interaction: Click reverses bidirectional edges
4. ✓ Interaction: Non-bidirectional edges don't reverse
5. ✓ Compatibility: Works across all layouts
6. ✓ Quality: No browser console errors
7. ✓ Performance: Acceptable on large diagrams

### Quick Start
```bash
# 1. Verify setup
./test-edge-directionality.sh

# 2. Open browser
open http://localhost:5173/uml-viewer

# 3. Follow test checklist
# See: MANUAL_TESTING_RESULTS.md
```

## 🚀 Next Action

**You need to**: 
1. Open browser to http://localhost:5173/uml-viewer
2. Load test diagram
3. Complete 5-10 manual tests
4. Document results
5. Report any bugs found

**Estimated time**: 20-40 minutes

**When complete**:
- Mark tests as passing/failing in MANUAL_TESTING_RESULTS.md
- Add this summary to PROGRESS.md
- Move to Phase 2 or next project task

## 💡 Key Points

### What Works (Verified)
- ✅ Code compiles
- ✅ Page loads
- ✅ All features implemented
- ✅ Test diagrams ready
- ✅ Documentation complete

### What's Unknown (Needs Testing)
- ❓ Do arrow markers render correctly in browser?
- ❓ Do hover effects work smoothly?
- ❓ Does click-to-reverse work as expected?
- ❓ Are there any console errors?
- ❓ Is performance acceptable?

### Why Manual Testing Required
- Browser rendering can differ from code expectations
- User interactions need real testing
- Performance must be validated with real diagrams
- Console errors only appear at runtime
- Visual quality needs human verification

## 📊 Risk Assessment

**Low Risk Areas** ✅:
- Implementation follows proven patterns (RDF viz)
- Code structure is sound
- TypeScript types are correct
- D3.js transitions are standard

**Medium Risk Areas** ⚠️:
- Performance with very large diagrams (200+ nodes)
- Browser compatibility (mainly tested concept)
- Edge case handling (rapid clicks, layout switches)

**Mitigation**: Comprehensive manual testing will catch any issues
