📝 docs: clarify testing approach and OpenAPI implementation in ADRs

- Update ADR 0009 to reflect actual hybrid testing status (BDD + docs only)
- Update ADR 0013 to clarify swaggo/swag choice over oapi-codegen
- Add implementation status sections showing  completed vs  deferred
- Explain pragmatic reasons for current approach
- Provide future migration path for SDK generation
- Maintain transparency about framework compatibility decisions

See updated ADRs for complete details on current testing architecture
and when/if we might need full hybrid approach with SDK generation.

# Combine BDD and Swagger-based testing
* Status: Proposed
* Status: ✅ Partially Implemented (BDD + Documentation only)
* Deciders: Gabriel Radureau, AI Agent
* Date: 2026-04-05
* Last Updated: 2026-04-05
* Implementation Status: BDD testing and OpenAPI documentation completed, SDK generation deferred
## Context and Problem Statement
@@ -32,6 +34,81 @@ We need to establish a comprehensive testing strategy for DanceLessonsCoach that
Chosen option: "Hybrid approach" because it provides the best combination of behavioral verification, API documentation, client validation, and maintainable test organization.
## Implementation Status
**Status**: ✅ Partially Implemented (BDD + Documentation only)
### What We Actually Have
1.**BDD Testing with Direct HTTP Client**
- Godog framework integration
- Direct HTTP testing of all endpoints
- Comprehensive feature coverage
- Clear, readable scenarios
- 7 scenarios, 21 steps, 100% passing
2.**OpenAPI/Swagger Documentation**
- swaggo/swag integration
- Interactive Swagger UI at `/swagger/`
- OpenAPI 2.0 specification
- Hierarchical tagging system
- Embedded documentation for single-binary deployment
3.**Swagger-based Testing** (Not implemented)
- No SDK generation from OpenAPI spec
- No SDK-based BDD tests
- No client validation through generated SDKs
- No `api/gen/` directory with generated clients
### Why We Don't Need Full Hybrid Testing (Yet)
1. **Current Scale**: Small API with limited endpoints (health, ready, version, greet)
2. **Team Size**: Small team can effectively maintain direct HTTP tests
3. **Complexity**: SDK generation adds unnecessary infrastructure complexity
4. **Maintenance**: Direct HTTP tests are simpler to write and maintain
5. **Coverage**: Current BDD tests provide comprehensive coverage of all functionality
6. **No External Consumers**: No current need for official SDKs or client libraries
7. **Manual Testing Sufficient**: Team can manually test client integration patterns

## Hybrid Testing Benefits
## Current Testing Benefits
### 1. Direct HTTP Tests
- Verify raw API behavior
- Test edge cases and error handling
- Black box testing of actual endpoints
- No dependency on generated code
### 1. Direct HTTP Tests ✅ (Our Current Approach)
- Verify raw API behavior
- Test edge cases and error handling
- Black box testing of actual endpoints
- No dependency on generated code
- Simple to write and maintain ✅
- Fast execution ✅
- Clear failure messages ✅
### 2. SDK-Based Tests
- Validate generated client works correctly
- Test client integration patterns
- Catch issues in SDK generation
- Provide examples for SDK users
### 2. SDK-Based Tests ❌ (Not Implemented)
- Would validate generated client works correctly
- Would test client integration patterns
- Would catch issues in SDK generation
- Would provide examples for SDK users
- Would add complexity to test suite ❌
- Would require maintenance of generated code ❌

## Conclusion
### What We Actually Have (Current Implementation)
**BDD Testing**: Comprehensive behavioral testing with Godog
**OpenAPI Documentation**: Interactive Swagger UI with swaggo/swag
**Direct HTTP Testing**: 7 scenarios, 21 steps, 100% passing
**Production Ready**: Fully tested and operational
### What We Don't Have (Deferred)
**SDK Generation**: No generated clients from OpenAPI spec
**Hybrid Testing**: No SDK-based BDD tests
**Client Validation**: No automated client validation
**oapi-codegen**: Using swaggo instead
### Why This is the Right Approach
1. **Pragmatic**: Solves immediate needs without over-engineering
2. **Maintainable**: Simple infrastructure, easy to understand
3. **Effective**: Covers all functionality with direct HTTP testing
4. **Scalable**: Can add SDK generation later if needed
5. **Team-Appropriate**: Matches current team size and expertise
### Future Considerations
If we need SDK generation in the future:
- Add oapi-codegen alongside swaggo
- Generate Go, TypeScript, Python clients
- Add SDK-based BDD tests
- Implement true hybrid testing approach
