## 🚀 Quick Start (3 Steps)

### Step 1: Open Browser
```
👉 http://localhost:5173/uml-viewer
```

### Step 2: Open DevTools
Press **F12** (or **Cmd+Option+I** on Mac)

### Step 3: Load Test Diagram
Choose from file picker:
- **Start with**: `NetworkOrganisation_20251123_225712.mmd` (small, quick validation)
- **Then try**: `full_schema_20251123_174151.mmd` (large, performance test)

## 📋 What to Test

### 🎯 Primary Tests (5-10 minutes)

1. **Hover over edges** → Should highlight with larger arrows
2. **Click association edges** (filled triangle) → Should reverse direction with flash
3. **Click inheritance edges** (hollow triangle) → Should do nothing (correct!)
4. **Switch layouts** (Force → Dagre) → Interactions should still work
5. **Check console** (F12) → Should have no errors

### 🎯 Secondary Tests (If time permits)

6. **Performance** → Load large diagram, hover rapidly
7. **Label visibility** → Labels should appear on hover
8. **Flash timing** → Click animation should be ~500ms
9. **Multiple clicks** → Should toggle direction repeatedly
10. **Cursor changes** → Pointer on bidirectional, default on others

## 🐛 If You Find Issues

### Report Format
```markdown
**Bug**: [Brief description]
**Test**: Test #[number]
**Browser**: Chrome/Firefox/Safari [version]
**Steps**: 1. ... 2. ... 3. ...
**Expected**: [What should happen]
**Actual**: [What actually happened]
**Console**: [Any error messages]
```

**Where to report**: Add to `MANUAL_TESTING_RESULTS.md` → "Bug Report Template" section

## 📊 Success Criteria

Feature passes when:
- ✅ All arrow types render correctly
- ✅ Hover effects work smoothly
- ✅ Bidirectional edges reverse on click
- ✅ Non-bidirectional edges ignore clicks
- ✅ Works across all 5 layouts
- ✅ No browser console errors
- ✅ Performance acceptable on large diagrams

## 🎨 Visual Reference

### Edge Types to Look For

```
Association (reversible):    A ──▶ B
Aggregation (reversible):    A ──◇ B
Inheritance (fixed):         A ──▷ B
Composition (fixed):         A ──♦ B
```

### Expected Interactions

**Hover** (any edge):
- Edge becomes fully opaque (opacity 1.0)
- Edge thickens (2px → 3px)
- Arrow grows 30% larger
- Label becomes bold and visible

**Click** (association/aggregation):
- Flash animation (edge pulses)
- Direction reverses (arrow flips)
- Source and target swap
- Label briefly highlights

**Click** (inheritance/composition):
- No effect (correct behavior!)
- Direction stays the same

## ⏱️ Time Estimates

- **Quick validation** (Tests 1-5): 5-10 minutes
- **Full test suite** (Tests 1-10): 15-30 minutes
- **Bug documentation**: 5 minutes per bug
- **Total estimated**: 20-40 minutes

---

## 🎯 What Happens Next

### If All Tests Pass ✅
1. Mark feature as **production-ready**
2. Celebrate! 🎉
3. Consider Phase 2 enhancements
4. Update project progress

### If Bugs Found 🐛
1. Document in testing results
2. Prioritize by severity
3. Fix and re-test
4. Iterate until clean

### Phase 2 Ideas 💡
- Custom bidirectional mappings (load from schema)
- Right-click context menu for edges
- Curved edges (route around nodes)
- Animated arrow rotation
- Edge history (undo/redo)

### Common Questions

**Q**: Page doesn't load?  
**A**: Check dev server running: `lsof -i :5173`

**Q**: Edges don't reverse?  
**A**: Make sure you're clicking association/aggregation edges (not inheritance)

**Q**: No arrows visible?  
**A**: Check browser console for marker definition errors

**Q**: Performance slow?  
**A**: Large diagrams (200+ nodes) may take 2-3 seconds to render

**Q**: How do I know which edges are reversible?  
**A**: Hover over edge - cursor changes to **pointer** if reversible
