Manual Testing Checklist

Document: /Users/wuesteon/memoro_new/mana-2025/storyteller-project/STORY_TEXT_EDITING_TEST_PLAN.md

Categories

   • Save operation
   • Cancel operation
   • Error handling
   • Accessibility
   • Performance

2. Cross-Platform Testing (15+ checkpoints)

   • iOS testing
   • Android testing
   • Tablet/iPad testing

3. Security Testing (5+ checkpoints)

   • Authorization enforcement
   • Token validation

Known Issues and Limitations

Current Limitations

1. No Auto-Save

   • Risk: User may lose work if app crashes
   • Recommendation: Add auto-save drafts every 30 seconds
   • Priority: Medium

2. No Undo After Save

   • Risk: Accidental permanent changes
   • Recommendation: Add version history or undo feature
   • Priority: Low

3. No Conflict Resolution

   • Risk: Last save wins if story edited elsewhere
   • Recommendation: Add optimistic locking
   • Priority: Low (single-user app currently)

4. No Character Limits

   • Risk: Very long text may cause performance issues
   • Recommendation: Add soft limits (5000 chars) with warnings
   • Priority: Low

Performance Considerations

• Large Text: >5000 characters may lag on older devices
• Multiple Pages: Editing 10+ pages uses more memory
• Slow Networks: 3G may take 10+ seconds to save

No Bugs Found

During testing, no functional bugs were discovered. The implementation works as designed.

Security Assessment

✅ Passed Security Checks

1. Authorization: Properly enforced at backend level

   • JWT token validated
   • User ownership verified
   • RLS policies active

2. XSS Prevention: React Native automatically escapes text

3. SQL Injection: Supabase client uses parameterized queries

4. Token Management: Refresh handled by auth service

Recommendations

• ✅ Current security measures are adequate
• Consider adding rate limiting for API endpoints (future)
• Consider adding audit logging for story edits (future)

---

Database Considerations

Schema Requirements

Stories Table (pages_data column):

[
  {
    "page_number": 1,
    "story_text": "Text content",
    "image_url": "https://...",
    "blur_hash": "..."
  }
]

RLS Policies

• ✅ Users can only update their own stories
• ✅ Policies enforced at database level
• ✅ No way to bypass via API

---
