## ❌ Tests Requiring Fixes

### 3. ConfigurationFileAdapterTest (4/11 passing, 7 failures/errors)
**Status**: ❌ **NEEDS FIX**

**Root Cause**: Test JSON configurations have invalid `pollingIntervalSeconds` values

**Failing Tests**:
1. `shouldUseDefaultValues_forOptionalFields` - ERROR
   - **Issue**: `pollingIntervalSeconds` is missing or 0, needs to be between 1-3600

2. `shouldValidatePortNumber_range` - ERROR
   - **Issue**: Invalid polling interval in test JSON

3. `shouldValidateHttpEndpoint_urls` - ERROR
   - **Issue**: Invalid polling interval in test JSON

4. `shouldValidateHttpEndpoints_notEmpty` - ERROR
   - **Issue**: Missing httpEndpoints array

5. `shouldValidateBufferSize_isPositive` - ERROR
   - **Issue**: Empty string for bufferCapacity, also invalid polling interval

6. `shouldHandleFile_withBOM` - FAILURE
   - **Issue**: UTF-8 BOM test has invalid polling interval

7. `shouldValidateConfiguration_successfully` - ERROR
   - **Issue**: Invalid polling interval in test JSON

**Fix Required**:
Read ConfigurationFileAdapterTest.java and fix test JSON strings to have valid `pollingIntervalSeconds` values (between 1 and 3600).

---

### 4. ConfigurationValidatorTest (5/11 passing, 6 errors)
**Status**: ❌ **NEEDS FIX**

**Root Cause**: Tests expect validation to return error messages, but Configuration constructor throws exceptions instead

**Failing Tests**:
1. `shouldRejectEmptyEndpoints` - ERROR
   - **Expected**: ValidationResult with error message
   - **Actual**: IllegalArgumentException thrown

2. `shouldRejectEmptyGrpcHost` - ERROR
   - **Expected**: ValidationResult with error message
   - **Actual**: IllegalArgumentException thrown

3. `shouldCollectMultipleErrors` - ERROR
   - **Expected**: ValidationResult with multiple errors
   - **Actual**: IllegalArgumentException thrown

4. `shouldRejectInvalidGrpcPort` - ERROR
   - **Expected**: ValidationResult with error message
   - **Actual**: IllegalArgumentException thrown

5. `shouldRejectPollingIntervalTooShort` - ERROR
   - **Expected**: ValidationResult with error message
   - **Actual**: IllegalArgumentException thrown

6. `shouldRejectPollingIntervalTooLong` - ERROR
   - **Expected**: ValidationResult with error message
   - **Actual**: IllegalArgumentException thrown

**Fix Required**:
Either:
- **Option A**: Update tests to expect and catch exceptions using `assertThrows()`
- **Option B**: Refactor Configuration to use builder pattern with validation that returns results instead of throwing

**Recommendation**: Option A is simpler and maintains current design

### 5. GrpcStreamingAdapterTest (10/11 passing, 1 failure)
**Status**: ❌ **NEEDS MINOR FIX**

**Failing Test**:
- `shouldFailToSend_whenNotConnected`
  - **Expected exception**: `IllegalStateException`
  - **Actual exception**: `GrpcStreamException`

**Fix Required**:
Change test expectation from `IllegalStateException.class` to `GrpcStreamException.class` in line 188-189.

---

### 6. ConfigurationManagerTest (11/12 passing, 1 failure)
**Status**: ❌ **NEEDS MINOR FIX**

**Failing Test**:
- `shouldRejectMissingRequiredFields`
  - **Issue**: Exception message doesn't contain expected text about "missing field"
  - **Actual**: Exception message is "Polling interval must be between 1 second and 1 hour"

**Fix Required**:
Update test expectation to match actual exception message, or fix test JSON to have valid polling interval so it fails on the missing field instead.

---

### 7. DataTransmissionServiceTest (25/30 passing, 5 failures)
**Status**: ❌ **NEEDS FIX**

**Failing Tests**:

1. `shouldDisconnectGrpcOnShutdown` (GracefulShutdownTests)
   - **Expected**: disconnect() called >= 1 time
   - **Actual**: disconnect() called 0 times
   - **Root Cause**: DataTransmissionService.shutdown() may not be calling disconnect() properly

2. `shouldContinueAfterTransmissionError` (ErrorHandlingTests)
   - **Expected**: streamData() called >= 2 times
   - **Actual**: streamData() called 1 time
   - **Root Cause**: Service not retrying after transmission error

3. `shouldLogReconnectionAttempts` (ReconnectionLogicTests)
   - **Expected**: Log message contains "reconnect" (case insensitive)
   - **Actual**: Log says "Failed to connect to gRPC server (attempt N), retrying in 5s..."
   - **Root Cause**: Log message doesn't contain word "reconnect"

4. `shouldDisconnectOnShutdown` (GrpcStreamLifecycleTests)
   - **Expected**: disconnect() called >= 1 time
   - **Actual**: disconnect() called 0 times
   - **Root Cause**: Same as #1

5. `shouldNotExceed4MBBatchSize` (BatchAccumulationTests)
   - **Expected**: batches sent >= 2
   - **Actual**: batches sent = 1
   - **Root Cause**: Batch size calculation or test timing issue

**Fix Required**:
- Review DataTransmissionService.shutdown() implementation
- Fix disconnect() call in shutdown sequence
- Update log message to include "reconnect" or "reconnection"
- Review batch accumulation logic

---

### 8. BackpressureAwareCollectionServiceTest (13/15 passing, 2 errors)
**Status**: ❌ **NEEDS FIX** (Java 25 Mockito issue)

**Failing Tests**:
1. `shouldHandleBackpressureControllerExceptionsGracefully` - ERROR
2. `shouldPauseCollectionDuringBackpressure` - ERROR

**Root Cause**:
```
Mockito cannot mock this class: class com.siemens.coreshield.hsp.application.BackpressureController
```

This is a Java 25 compatibility issue with Mockito. BackpressureController might be:
- A final class
- Using sealed classes or records
- Using preview features that Mockito doesn't support yet

**Fix Required**:
- Option A: Make BackpressureController mockable (remove final, add open keyword)
- Option B: Use real BackpressureController instance instead of mocking
- Option C: Create manual test double instead of using Mockito

2. Review and fix DataTransmissionService shutdown behavior
3. Address Mockito/Java 25 compatibility for BackpressureAwareCollectionServiceTest
4. Run full test suite to verify all fixes
5. Update this document with final results

## Architecture Improvements Completed

✅ **Dependency Inversion Principle Applied**:
- Created service interfaces (IDataCollectionService, IDataTransmissionService)
- Controllers now depend on interfaces, not concrete implementations
- Test mocks properly injectable
- Proper Hexagonal Architecture compliance

✅ **Test Infrastructure**:
- All compilation errors resolved
- Proper exception handling in tests
- Thread-safe test implementations
- Mock services implement required interfaces
