## 🚀 Quick Start Commands
|
||||
|
||||
```bash
|
||||
# Run all MCP tests
|
||||
pnpm test -- src/modules/mcp
|
||||
|
||||
# Run specific test file
|
||||
pnpm test -- src/modules/mcp/presentation/__tests__/mcp-transport.controller.spec.ts
|
||||
|
||||
# Watch mode during development
|
||||
pnpm test -- --watch src/modules/mcp
|
||||
|
||||
# Generate coverage report
|
||||
pnpm test -- --coverage src/modules/mcp
|
||||
```
|
||||

|
||||
|
||||
## 💡 Next Steps Recommended
|
||||
|
||||
### High Priority (Do These First)
|
||||
1. Add tests for `McpIntegrationModule.onModuleInit()`
|
||||
2. Test module dependency injection
|
||||
3. Verify TypesenseClient initialization
|
||||
|
||||
### Medium Priority (Consider These)
|
||||
1. Add integration tests for full SSE lifecycle
|
||||
2. Test session timeout and cleanup
|
||||
3. Add error recovery tests
|
||||
|
||||
### Low Priority (Future Enhancement)
|
||||
1. Implement domain layer if more business logic is added
|
||||
2. Add application handlers (CQRS) if needed
|
||||
3. Implement infrastructure layer for persistence
