full_schema_20251123_174151.mmd (264 lines, comprehensive schema)
core_classes_20251123_174151.mmd (all core classes)

🧪 Test Cases (Manual Browser Testing Required)

✅ Test 1: Arrow Markers Render Correctly

Steps:

Open http://localhost:5173/uml-viewer in browser
Load any diagram from the file picker
Inspect edges visually

Expected:

Inheritance: Hollow triangle arrows (white fill, dark stroke)
Composition: Filled diamond arrows (dark fill)
Aggregation: Hollow diamond arrows (white fill, dark stroke)
Association: Filled triangle arrows (dark fill)
All arrows clearly visible at default opacity (0.8)

Visual Reference:

Inheritance:   A ──▷ B  (hollow triangle)
Composition:   A ──♦ B  (filled diamond)
Aggregation:   A ──◇ B  (hollow diamond)
Association:   A ──▶ B  (filled triangle)

✅ Test 2: Hover Effects Work Smoothly

Steps:

Hover mouse over any edge
Observe visual changes
Test multiple edge types

Expected:

Edge opacity: 0.7 → 1.0 (becomes fully opaque)
Edge width: 2px → 3px (thickens slightly)
Arrow switches to highlight marker (30% larger)
Label opacity: 0.7 → 1.0 (fully visible)
Label font-weight: normal → bold
Transition duration: ~200ms (smooth, not instant)

Browser DevTools Check:

// Open Console (F12) and hover over edge
// Inspect element should show:
<line stroke-opacity="1" stroke-width="3" marker-end="url(#arrow-association-highlight)">

✅ Test 3: Click to Reverse (Bidirectional Edges)

Steps:

Identify an association edge (filled triangle)
Hover over the edge
Verify cursor changes to pointer (hand icon)
Click the edge
Observe the animation and direction change

Expected:

Before click: Edge points A → B
Cursor: Changes to pointer on hover (indicates clickable)
Click effect: Flash animation (edge widens briefly)
After click: Edge now points B → A (reversed)
Label flash: Label briefly highlights, then returns to normal
Animation timing: 300ms expand + 200ms contract = 500ms total

Test on multiple edge types:

Association edges: Should reverse
Aggregation edges: Should reverse
Try clicking same edge again: Should reverse back

✅ Test 4: Non-Bidirectional Edges Don't Reverse

Steps:

Identify an inheritance edge (hollow triangle)
Hover over the edge
Verify cursor stays default (arrow icon, not pointer)
Click the edge

Expected:

Cursor: Stays as default arrow (NOT pointer)
Click effect: No animation, no direction change
Edge direction: Remains unchanged (inheritance is hierarchical)
Console: No errors

Repeat for composition edges (filled diamond):

Composition edges should also NOT reverse

Rationale: Inheritance and composition have strict semantic meaning (not reversible)

✅ Test 5: Tooltips (If Implemented)

Steps:

Hover over a bidirectional edge (association/aggregation)
Wait 1 second

Expected:

Tooltip appears: "Click to reverse direction"
Tooltip positioned near cursor
Tooltip disappears on mouseout

Steps:

Hover over a non-bidirectional edge (inheritance/composition)

Expected:

No tooltip OR generic tooltip (without "click to reverse")

Note: Tooltip implementation may not be in this version (check code)

✅ Test 6: Layout Algorithm Compatibility

Steps:

Load diagram with Force-directed layout (default)
Test hover and click on edges
Switch to Dagre layout (hierarchical)
Test hover and click again
Repeat for other layouts (Grid, Radial, Circular)

Expected:

All interactions work in Force layout
All interactions work in Dagre layout
All interactions work in Grid layout
All interactions work in Radial layout
All interactions work in Circular layout
No console errors when switching layouts
Edge states persist across layout changes

✅ Test 7: Label Display with Cardinality

Steps:

Load diagram with edges that have cardinality (e.g., hasCollection [1..*])
Observe label display at rest
Hover over edge

Expected:

At rest: Labels semi-transparent (opacity 0.7)
At rest: Labels reduced visual clutter
On hover: Labels fully visible (opacity 1.0, bold)
Content: Shows cardinality if present: "hasCollection [1..*]"
Position: Midpoint of edge
Pointer events: Labels don't interfere with edge clicks

✅ Test 8: Performance with Large Diagrams

Steps:

Load full_schema_20251123_174151.mmd (264 lines, ~100+ nodes)
Wait for initial render
Pan and zoom around the diagram (mouse drag, scroll wheel)
Hover rapidly over multiple edges (mouse sweep)
Click several bidirectional edges in quick succession

Expected:

Initial render: Completes in < 3 seconds
Pan/zoom: Smooth, no stuttering
Hover: Highlights trigger within 100ms
Click animations: Complete smoothly (no frame drops)
Browser CPU: Stays reasonable (check DevTools Performance tab)
Memory: No memory leaks (check DevTools Memory tab)

Performance Benchmarks (estimated):

Small diagram (10 nodes): ~135ms render
Medium diagram (50 nodes): ~490ms render
Large diagram (200 nodes): ~1920ms render

Acceptable slowdown: ~10% overhead from edge interactions

✅ Test 9: Browser Console - No Errors

Steps:

Open Browser DevTools (F12)
Navigate to Console tab
Load UML viewer
Load diagram
Interact with edges (hover, click)
Check for errors

Expected:

No TypeScript compilation errors
No D3.js errors
No marker reference errors (e.g., url(#arrow-association) not found)
No React warnings
No memory warnings

Common errors to watch for:

❌ Cannot read property 'type' of undefined (data binding issue)
❌ Marker 'arrow-association-highlight' not found (marker definition missing)
❌ Transition interrupted (animation conflicts)

✅ Test 10: Flash Animation Timing

Steps:

Click a bidirectional edge
Observe the flash animation carefully
Time the animation (use phone stopwatch or DevTools Performance)

Expected:

Phase 1: Edge width 2px → 3px (300ms expand)
Phase 2: Edge width 3px → 2px (200ms contract)
Total: 500ms flash duration
Smooth: No abrupt jumps, smooth D3 transition
Label sync: Label flashes in sync with edge

Animation curve:

Width
3px   ╭─────╮
      │     │
2px ──╯     ╰────────
    0   300ms  500ms
       (expand) (contract)

🐛 Known Issues (Unrelated to Edge Feature)

TypeScript Compilation Warnings (Other files):

ConnectionAnalysisPanel.tsx: Unused imports (doesn't affect UML viewer)
InteractiveGraph.tsx: Unused variables (different component)
Navigation.tsx: SVG prop type mismatch (doesn't affect functionality)
rdf-extractor.ts: Unused baseUri parameters (RDF module, not UML)

Impact: ❌ None - These warnings are in unrelated components
