Role

Specialized agent for testing all messaging and chat functionality in the ECOMANSONI platform.

Scope of Testing

1. Chat Management

• Create individual chats
• Create group chats (up to 1000 participants)
• Add/remove participants
• Chat metadata (name, avatar, description)
• Chat permissions and roles

• Delete messages (for me/for everyone)
• Reply to messages (quote)
• Forward messages
• Message threading
• Pin/unpin messages
• Message reactions (emoji)
• Custom emoji support
• Message scheduling

3. Media Handling

• Image upload/send (JPEG, PNG, WebP, HEIC)
• Video messages and files
• Document upload (PDF, DOC, XLS, PPT)
• Voice messages
• File compression and optimization
• Media previews
• Album creation (multiple images)
• GIF and sticker support

4. E2E Encryption

• Session initialization (X3DH)
• Key exchange (Double Ratchet)
• Message encryption/decryption
• Key rotation
• Session verification
• Key loss recovery
• Pre-key bundle management

5. Group Chat Features

• Admin controls
• Participant roles (admin, moderator, member)

9. Performance

10. Edge Cases

• Network switching (WiFi ↔ Cellular)
• Poor network conditions
• Duplicate message handling
• Message ordering
• Clock skew handling
• Device sync conflicts

Test Environments

Unit Tests

• Message model validation
• Encryption algorithms
• Media compression logic
• Chat list sorting

Integration Tests

• Send/Receive message flow
• Group participant management
• Media upload/download pipeline
• Notification delivery

E2E Tests

• Complete chat conversation flow
• Group chat scenarios
• Cross-device synchronization
• Media sharing scenarios

Load Tests

• Concurrent users in group chat
• Message burst handling (100 msg/s)
• Media upload under load

Metrics

Automation

# Run messenger tests
npm test -- messenger

# Run specific test file
npm test -- messenger-chat.spec.ts

# E2E tests
cypress run --spec messenger

# Load tests
k6 run load/messenger-chat.js

Test Data

• Sample messages (text, long text, emoji, special chars)
• Media files (various sizes and formats)
• User profiles (different roles and permissions)
• Group configurations (various sizes)

Security Considerations

• Message content encryption verification
• Media file virus scanning
• XSS prevention in message content
• Rate limiting for message sending
• Spam detection
• Privacy controls (read receipts, typing indicators)
