HSP Test Status Report

Date: 2025-11-20 Status: Partial Success - 2 test classes fixed, 6 test classes need fixes

✅ Successfully Fixed Tests

1. LifecycleControllerTest (14/14 tests passing)

Status: ✅ COMPLETE

What was fixed:

• Created IDataCollectionService and IDataTransmissionService interfaces
• Refactored LifecycleController to accept interfaces instead of concrete classes
• Updated test mocks to implement new interfaces
• Fixed checked exception handling in tests
• Removed @Disabled annotation

Test Groups:

• GrpcRetryTests: 3 tests ✅
• StateManagementTests: 3 tests ✅
• ShutdownTests: 4 tests ✅
• StartupSequenceTests: 4 tests ✅

2. HealthCheckControllerTest (11/11 tests passing)

Status: ✅ COMPLETE

What was fixed:

• Updated HealthCheckController to accept service interfaces
• Fixed JSON format expectations (nested component objects)
• Fixed lifecycle state initialization
• Fixed uptime assertion to accept >= 0
• Removed @Disabled annotation

Test Groups:

• HealthCheckResponseTests: 6 tests ✅
• HttpServerTests: 5 tests ✅

❌ 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

Priority Fixes (by impact)

🔴 HIGH PRIORITY

1. ConfigurationFileAdapterTest - Fix test JSON polling intervals (quick fix)
2. ConfigurationValidatorTest - Update test expectations for exceptions (quick fix)
3. GrpcStreamingAdapterTest - Fix exception type expectation (1-line fix)

🟡 MEDIUM PRIORITY

4. DataTransmissionServiceTest - Fix shutdown disconnect and logging (implementation review)
5. ConfigurationManagerTest - Fix test JSON or expectation (quick fix)

🟢 LOW PRIORITY

6. BackpressureAwareCollectionServiceTest - Mockito/Java 25 compatibility (requires design decision)

---

Next Steps

1. Fix high-priority test issues (ConfigurationFileAdapterTest, ConfigurationValidatorTest, GrpcStreamingAdapterTest)
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
