## 🚨 CRITICAL BLOCKERS (Cannot Run Application)
|
|
|
|
### 1. HspApplication Main Class ❌ NOT IMPLEMENTED
|
|
**File**: `src/main/java/com/siemens/coreshield/hsp/HspApplication.java`
|
|
**Status**: Missing
|
|
**Priority**: **BLOCKER** - Application cannot start without main entry point
|
|
**Requirements**: Req-FR-1 to FR-8, Req-Arch-5
|
|
**Deliverables**:
|
|
- Main method with startup sequence
|
|
- Dependency injection (manual or framework)
|
|
- Component initialization order:
|
|
1. Load configuration (ConfigurationFileAdapter)
|
|
2. Validate configuration (ConfigurationValidator)
|
|
3. Initialize BufferManager
|
|
4. Connect to gRPC (retry loop 5s until success)
|
|
5. Start HealthCheckController (HTTP server on port 8080)
|
|
6. Start DataCollectionService (HTTP polling)
|
|
7. Start DataTransmissionService (gRPC transmission)
|
|
- Graceful shutdown hooks
|
|
- Signal handling (SIGTERM, SIGINT)
|
|
|
|
**Estimated Effort**: 3 days (Phase 3.7)

## 🔴 HIGH PRIORITY (Feature Incomplete)
|
|
|
|
### 3. DataTransmissionService Test Failures ⚠️ 5 FAILURES
|
|
**File**: `src/main/java/com/siemens/coreshield/hsp/application/DataTransmissionService.java`
|
|
**Status**: Partial implementation (24/29 tests passing)

|
|
4. `DataTransmissionServiceTest$GrpcStreamLifecycleTests`: 1 failure
|
|
5. `DataTransmissionServiceTest$BatchAccumulationTests`: 1 failure

|
|
**Priority**: LOW - Test bug, not production issue
|
|
**Failing Test**: `shouldFailToSend_whenNotConnected`
|
|
**Root Cause**: Test expects `IllegalStateException` but production throws `GrpcStreamException`
|
|
**Fix**: Update test expectation to match production behavior
|
|
**Estimated Effort**: 0.1 days
|

**Priority**: LOW - Test bugs, not production issues
|
|
**Estimated Effort**: 0.1 days each

|
|
**Status**: Not implemented
|
|
**Priority**: OPTIONAL - Enhancement to linear backoff
|
|
**Requirements**: Req-FR-18 (enhanced)
