Tested via plugin/test package +2. `github.com/veraison/services/plugin/test` - Pure test code + +### Category 2: Protobuf-generated code (justified exclusion) +3. `github.com/veraison/services/handler` - Contains protobuf-generated code + +### Category 3: Packages without tests (Go 1.22+ reports 0% coverage) +4. `github.com/veraison/services/builtin` +5. `github.com/veraison/services/management/api` +6. `github.com/veraison/services/management/cmd/management-service` +7. `github.com/veraison/services/provisioning/cmd/provisioning-service` +8. `github.com/veraison/services/provisioning/provisioner` +9. `github.com/veraison/services/scheme/common` +10. `github.com/veraison/services/scheme/common/arm` +11. `github.com/veraison/services/verification/cmd/verification-service` +12. `github.com/veraison/services/verification/verifier` +13. `github.com/veraison/services/vts/cmd/vts-service` +14. `github.com/veraison/services/vts/trustedservices` +15. `github.com/veraison/services/vtsclient` + +## Analysis and Recommendations + +### HIGH PRIORITY: Should Add Unit Tests + +#### 1. `builtin` package +**Current State**: No unit tests +**Functionality**: +- BuiltinManager with generic type support +- BuiltinLoader for plugin discovery +- Media type registration and lookup +- Attestation scheme handling + +**Recommendation**: **ADD UNIT TESTS** +- **Reason**: Contains substantial business logic for plugin management +- **Test Areas**: + - BuiltinManager creation and initialization + - Media type registration and lookup + - Attestation scheme registration + - Error handling in CreateBuiltinManager functions + - Generic type behavior validation + +#### 2. `vtsclient` package +**Current State**: No unit tests +**Functionality**: +- gRPC client implementation for VTS communication +- Connection management with credentials +- Error handling with custom error types (NoConnectionError) + +**Recommendation**: **ADD UNIT TESTS** +- **Reason**: Critical communication layer with complex error handling +- **Test Areas**: + - GRPC client creation and configuration + - Connection establishment with different credential types + - Custom error type behavior (NoConnectionError) + - gRPC call handling and error propagation + +#### 3. `provisioning/provisioner` package +**Current State**: No unit tests, but tested via API layer +**Functionality**: +- Media type support validation +- VTS client interaction +- Input parameter validation + +**Recommendation**: **ADD UNIT TESTS** +- **Reason**: Contains business logic that should be unit tested independently +- **Test Areas**: + - IsSupportedMediaType logic + - Input parameter validation (ErrInputParam cases) + - VTS client interaction mocking + - SubmitCoRIM functionality + +#### 4. `verification/verifier` package +**Current State**: No unit tests, but tested via API layer +**Functionality**: +- Media type support validation +- Evidence processing +- VTS state retrieval + +**Recommendation**: **ADD UNIT TESTS** +- **Reason**: Core verification logic should be independently testable +- **Test Areas**: + - IsSupportedMediaType validation + - ProcessEvidence functionality + - GetVTSState error handling + - Input parameter validation + +#### 5. `scheme/common` package +**Current State**: No unit tests +**Functionality**: +- CCA platform/realm claim wrappers +- PSA platform claim wrappers +- Claims to map conversion utilities +- Certificate parsing utilities + +**Recommendation**: **ADD UNIT TESTS** +- **Reason**: Contains utility functions with complex JSON marshaling logic +- **Test Areas**: + - ClaimMapper implementations for CCA and PSA + - ClaimsToMap conversion function + - Certificate parsing (ParseCertificates function) + - JSON marshaling of different claim types + +### MEDIUM PRIORITY: Consider Adding Unit Tests + +#### 6. `vts/trustedservices` package +**Current State**: No unit tests +**Functionality**: +- Large gRPC service implementation (681 lines) +- Contains substantial business logic +- Policy management, attestation processing + +**Recommendation**: **CONSIDER UNIT TESTS** +- **Reason**: While primarily integration-tested, some business logic could benefit from unit tests +- **Areas to Consider**: + - Configuration validation + - Error handling logic + - State management functions + - Individual service method logic (mocked dependencies) + +### LOW PRIORITY: Maintain Current Exclusion + +#### 7. `management/api` package +**Current State**: No unit tests +**Recommendation**: **LOW PRIORITY** +- **Reason**: Likely thin API layer, already covered by integration tests + +#### 8. All `cmd/*-service` packages +**Current State**: No unit tests +**Recommendation**: **MAINTAIN EXCLUSION** +- **Reason**: Main entry points - better tested via integration tests +- **Packages**: management/cmd/management-service, provisioning/cmd/provisioning-service, verification/cmd/verification-service, vts/cmd/vts-service + +#### 9. `scheme/common/arm` package +**Current State**: No unit tests +**Recommendation**: **LOW PRIORITY** +- **Reason**: Needs investigation - directory structure suggests it may be scheme-specific utilities + +## Current Test Coverage Status + +**Coverage check is currently passing** with threshold of 60.0% + +The existing test coverage includes: +- Integration tests covering end-to-end workflows +- API handler tests with mocked dependencies +- Unit tests for non-excluded packages + +## Implementation Plan + +### Phase 1: High Priority Packages +1. **builtin** package - Focus on BuiltinManager and BuiltinLoader +2. **vtsclient** package - Focus on gRPC client and error handling +3. **provisioning/provisioner** package - Focus on business logic +4. **verification/verifier** package - Focus on verification logic +5. **scheme/common** package - Focus on claim processing utilities + +### Phase 2: Medium Priority +1. **vts/trustedservices** package - Focus on core business logic functions + +### Testing Strategy +- Use dependency injection with interfaces to enable mocking +- Focus on business logic rather than integration scenarios +- Maintain the existing integration test coverage +- Use table-driven tests for validation logic +- Mock external dependencies (VTS clients, gRPC connections) + +## Benefits of Adding Unit Tests + +1. **Earlier Error Detection**: Catch bugs during development +2. **Refactoring Safety**: Enable confident code changes +3. **Documentation**: Tests serve as usage examples +4. **Code Quality**: Force consideration of edge cases and error conditions +5. **Debugging**: Easier to isolate issues to specific functions + +## Conclusion + +While the current integration test coverage provides good end-to-end validation, adding unit tests to the **5 high-priority packages** would significantly improve the codebase's maintainability and robustness. These packages contain substantial business logic that would benefit from isolated testing. + +The exclusions for plugin-related packages, protobuf-generated code, and main entry points should be maintained as they are appropriately tested through other means. \ No newline at end of file diff --git a/builtin/builtin_test.go b/builtin/builtin_test.go new file mode 100644 index
