# Story 17: Testing, Optimization & Documentation
|
|
|
|
**Parent Epic**: [Story 0](sprint_5_story_0.md) - Integrate Microsoft .NET MCP SDK
|
|
**Phase**: 5 - Testing & Optimization (Week 7-8)
|
|
**Priority**: P0 - Critical
|
|
**Estimated Effort**: 10 days (2 weeks)
|
|
**Dependencies**: Story 16 (Transport migration complete)
|
|
|
|
## User Story
|
|
|
|
**As** a backend team lead,
|
|
**I want** comprehensive testing, performance optimization, and documentation for MCP SDK integration,
|
|
**So that** we have production-ready code with zero regressions and complete knowledge transfer.
|
|
|
|
## Business Value
|
|
|
|
- **Quality Assurance**: Zero CRITICAL bugs in production
|
|
- **Performance Validation**: Confirm ≥20% improvement target met
|
|
- **Security Confidence**: Pass security audit with zero HIGH vulnerabilities
|
|
- **Team Knowledge**: Complete documentation for future maintenance
|
|
- **Production Ready**: Confident deployment with rollback plan
|
|
|
|
