## Coverage Areas

### ✅ Fully Tested
- Radix tree routing (static and dynamic)
- Typed parameter validation (12 types)
- LRU caching with TTL
- Request body parsing (JSON, XML, form-data)
- Response methods (JSON, HTML, text, file, buffer)
- MIME type detection (28+ types)
- File serving with streaming
- Query parameter handling
- Error handling and 404s
- Redirects
- Path traversal protection

### ⚠️ Partially Tested
- Cookie management (basic functionality, needs integration tests)
- Middleware system (needs integration tests)
- HTTPS/SSL (needs integration tests)

### ❌ Not Yet Tested
- Multipart/form-data file uploads (needs real upload test)
- Large file streaming (needs stress test)
- Range requests (needs integration test)
- Object pooling (not yet implemented)
- Concurrent request handling (needs load test)

## Test Performance
