## 🧪 Test Strategy
|
||
|
||
### Test Pyramid
|
||
- **Unit Tests** (75%): 18 test classes for domain/adapters
|
||
- **Integration Tests** (20%): 9 test classes with mock servers
|
||
- **Performance Tests** (5%): 4 test classes (1000 endpoints, 4GB memory)
|
||
|
||
### Key Test Classes
|
||
- `ConfigurationLoaderTest` → Req-FR-11, FR-12, FR-13
|
||
- `CircularBufferTest` → Req-FR-25, FR-26, thread safety
|
||
- `HttpPollingServiceTest` → Req-NFR-1 (1000 endpoints)
|
||
- `GrpcStreamAdapterTest` → Req-FR-27 to FR-32
|
||
- `EndToEndDataFlowTest` → Complete IF1 → IF2 pipeline

## ⚠️ Critical Findings
|
||
|
||
### Issues Requiring Resolution
|
||
|
||
1. **🚨 CRITICAL: Buffer Size Conflict**
|
||
- Req-FR-25: "max 300 messages"
|
||
- Config Spec: "max_messages: 300000"
|
||
- **Action**: Stakeholder decision needed
|
||
|
||
2. **Duplicate Requirement IDs**
|
||
- Req-FR-25 (appears twice - lines 66, 67)
|
||
- Req-NFR-7 (appears twice - lines 100, 117)
|
||
- Req-NFR-8 (appears twice - lines 101, 118)
|
||
- Req-US-1 (appears three times - lines 126, 127, 128)
|
||
- **Action**: Renumber and clarify duplicates
|
||
|
||
### Recommendations
|
||
|
||
1. **Performance Testing**: Validate virtual thread scalability with 1000 endpoints
|
||
2. **Memory Testing**: Verify <4096MB under sustained load (24h, 72h, 7d)
|
||
3. **Graceful Shutdown**: Add proper cleanup sequence (not in requirements)
|
||
4. **Configuration Reload**: Add runtime reload capability (not in requirements)
|
||
5. **Metrics Export**: Add Prometheus/JMX metrics (not in requirements)
