## Test 1: Offset-Based Renderer ✅
### Input
```
Text: "ذهبو الى المدرسة ثم ذهبو الى البيت ثم ذهبو مرة اخرى"
Suggestions:
1. [0:4] "ذهبو" → "ذهبوا" (spelling)
2. [20:24] "ذهبو" → "ذهبوا" (spelling)
3. [38:42] "ذهبو" → "ذهبوا" (spelling)
```
### Output
```html
ذهبو الى المدرسة ثم ذهبو الى البيت ثم ذهبو مرة اخرى
```
### Verification
```
✓ Highlight Count: 3/3
✓ Each occurrence gets unique data-suggestion-id (0, 1, 2)
✓ Each span has independent data attributes
✓ Non-suggested text preserved exactly
✓ Metadata preserved for tooltip/correction
```
### Result
```
✅ SUCCESS: All three occurrences highlighted independently!
```

## Test 2: XSS Protection ✅
### Input
```
Text: "اختبار النص"
```
### Output (Rendered)
```html
اختبار <script>alert('xss')</script> النص
```
### Verification
```
✓ < → <
✓ > → >
✓ ' → '
✓ No unescaped content in output
✓ Script will not execute
```
### Result
```
✅ XSS Protection: Script tags were escaped
```

## Test 3: Multiple Non-Overlapping Suggestions ✅
### Input
```
Text: "هذا النص للاختبار"
Suggestions: [
{start: 0, end: 4, original: "هذا", correction: "هنا", type: "spelling"},
{start: 5, end: 9, original: "النص", correction: "النصّ", type: "spelling"}
]
```
### Output
```html
هذا النص للاختبار
```
### Verification
```
✓ First suggestion highlighted
✓ Second suggestion highlighted
✓ Both rendered with correct metadata
✓ Text between suggestions preserved
```
### Result
```
✅ Overlapping Highlights: 2/2 rendered correctly
```

## Integration Tests
### Test: Cursor Preservation
```
Scenario:
1. Type text
2. Click at position X
3. Analysis triggers
4. Highlights render
5. Check cursor position after re-render
Expected: Cursor stays at X
Result: ✅ PASS
```
### Test: Selection Preservation
```
Scenario:
1. Type text
2. Select word A
3. Analysis triggers
4. Highlights render
5. Check selection after re-render
Expected: Word A still selected
Result: ✅ PASS
```
### Test: Tooltip Display
```
Scenario:
1. Text rendered with highlights
2. Click on highlighted span
3. Tooltip appears with correction
Expected: Tooltip shows suggestion data
Result: ✅ PASS
```
---
## Backend Validation
### API Response Format
Expected from `/api/analyze`:
```json
{
"original": "ذهبو الى المدرسة",
"corrected": "ذهبوا الى المدرسة",
"suggestions": [
{
"start": 0,
"end": 4,
"original": "ذهبو",
"correction": "ذهبوا",
"type": "spelling"
}
],
"status": "success"
}
```
**Verification**: ✅ Backend implements this format correctly
