Add PDF Stamp Operation feature with endpoints and tests
...
Implemented the "PDF Stamp Operation" feature, allowing users to add text, image, or predefined stamps to PDF documents.
- Added `FEATURE_7_PLAN.md` with detailed implementation plan.
- Introduced enums (`StampType`, `PredefinedStampType`, `StampPlacement`) in the domain layer.
- Added `AddStampAsync` method to `IPdfProcessor` interface.
- Implemented `AddStampAsync` in `DevExpressPdfProcessor` using DevExpress API.
- Created unit tests for `AddStampAsync` covering various scenarios.
- Added `AddStampCommand` in the application layer with validation rules.
- Created two new endpoints in `PdfOperationsController` for multipart and Base64 inputs.
- Added DTOs for handling endpoint requests.
- Wrote integration tests for endpoints to ensure correctness.
- Updated `AGENTS.md` and added DevExpress API references.
- Documented challenges, considerations, and estimated effort.
This commit completes the "PDF Stamp Operation" feature with full test coverage and documentation.

Add IIS publish profile for Web Deploy packaging
Added `IISProfile.pubxml` to configure publishing via Web Deploy.
Set the publish method to `Package` and specified build settings
(`Release`, `Any CPU`). Configured the output package location,
enabled single-file packaging, and set the IIS app path to
`DocumentOperator.API`. Target framework updated to .NET 8.0.

test(integration): migrate integration tests to Controller DTOs and update assertions
...
Test Changes:
- Use Controller DTOs (ValidatePdfBase64Request, ValidatePdfABase64Request, CheckPdfAttachmentsRequest, ExtractSwissQrCodeBase64Request)
- Remove direct Query object usage in HTTP tests (architectural violation)
- Update imports: DocumentOperator.API.Controllers namespace
Assertion Updates:
- Invalid Base64 tests: case-insensitive regex (?i)base.?64 (FormatException message contains 'Base-64' with hyphen)
- Empty PDF tests: regex match for 'Base64|empty|stream' (flexible validation error matching)
- Corrupted PDF test: Expect 500 Internal Server Error (DevExpress exception propagates naturally)
Result: 52 tests pass, 6 skipped (IBAN validation - DevExpress limitation)

refactor(domain): remove obsolete exception types
...
Deleted:
- PdfProcessingException: Obsolete, DevExpress exceptions now propagate naturally
- SwissQrCodeNotFoundException: Moved to Application layer (feature-specific exception)
Rationale:
- PdfProcessingException was wrapping library exceptions unnecessarily
- Better to let infrastructure exceptions propagate → middleware handles as 500
- SwissQrCodeNotFoundException is application-level concern, not domain
2026-07-20 16:32:36 +02:00

refactor(api): remove generic exception handling from middleware
...
Remove FormatException/ArgumentException handling:
- These are framework exceptions, not application-specific
- May come from internal libraries (false positives for 400 Bad Request)
- Controllers now wrap Base64 conversion with BadRequestException explicitly
Remove PdfProcessingException handling:
- Exception type removed (obsolete)
- DevExpress exceptions now propagate naturally → 500 Internal Server Error
Current exception mapping:
- ValidationException (FluentValidation) → 400 Bad Request
- BadRequestException (custom) → 400 Bad Request
- NotFoundException (custom) → 404 Not Found
- SwissQrCodeNotFoundException (custom) → 404 Not Found
- All others → 500 Internal Server Error
