64be11f7ad Add tests for DevExpressPdfProcessor and roadmap updates
Updated ROADMAP.md to reflect progress on the TDD process for
DevExpressPdfProcessor, including the creation of unit tests
(6 tests in the Red Phase). Updated progress to 4/7 mini-steps
completed and outlined the next step (Green Phase).

Added `DevExpressPdfProcessorTests.cs` with unit tests to
validate PDF files and extract metadata. Tests cover valid
PDFs, null/empty inputs, corrupted PDFs, and file size
calculations. Used `FluentAssertions` for assertions.

Cleaned up `DocumentOperator.Tests.csproj` by removing an
unused folder reference. No functional changes to the project
structure.

b8c9e1b6a6 Update ROADMAP and test structure for DevExpressPdfProcessor
Updated ROADMAP.md to reflect progress on Phase 3, Step 3.2:
- Created test folder structure under Unit/Infrastructure/Services/PdfProcessing.
- Updated progress status to 2/7 mini-steps completed.
- Documented next step (adding a test PDF file) and marked DevExpressPdfProcessor.cs implementation as "IN PROGRESS."
- Highlighted availability of the DevExpress Universal License.

Modified DocumentOperator.Tests.csproj:
- Added the new test folder structure to the project file.

09cc64eff0 Refactor: Remove ProcessDocument and update roadmap
Removed the obsolete `ProcessDocument` folder and its files
(`ProcessDocumentCommand.cs`, `ProcessDocumentHandler.cs`,
`ProcessDocumentValidator.cs`) as part of Application Layer
cleanup. Updated `ROADMAP.md` to reflect progress, including
the start of `DevExpressPdfProcessor` implementation (Step 3.2)
and actionable steps for creating a test folder structure.
Documented the availability of the `DevExpress Universal License`.

867e0b2655 Remove unused UnitTest1 class and empty test method
The `UnitTest1` class in the `DocumentOperator.Tests` namespace was removed, including the `Test1` method, which was an empty test marked with the `[Fact]` attribute. This cleanup suggests the test class is no longer needed or has been replaced by other tests.

fc79665241 Update ROADMAP and add STATUS_UPDATE for project status
Extensively updated `ROADMAP.md` to reflect the current
project status, including documentation of the DevExpress
Universal License, completion of Phases 1 and 2, and
progress in Phase 3. Clarified discrepancies in the
Application Layer and identified gaps in the Tests Layer
and Infrastructure Services.

Created `STATUS_UPDATE_17_01_2025.md` to summarize the
current status, key learnings, and next steps. Outlined
a TDD-driven approach for implementing the
`DevExpressPdfProcessor` and cleaning up the Application
Layer. Confirmed build success and updated documentation
to align with the latest roadmap.

# ?? Status Update - DocumentOperator (17.01.2025)
## ? Was wurde aktualisiert?
Die **ROADMAP.md** wurde vollständig mit dem **tatsächlichen Projektstand** abgeglichen und aktualisiert.
---
## ?? Haupterkenntnisse
### 1. **DevExpress Universal License** ?
**Wichtig:** Das Projekt verfügt über eine **DevExpress Universal License**!
**Das bedeutet:**
- ? Vollzugriff auf **ALLE** DevExpress Bibliotheken
- ? Nicht nur `DevExpress.Pdf.Core` - wir können **jedes** DevExpress Paket nutzen
- ? Falls künftig Word/Excel-Verarbeitung benötigt wird ? einfach hinzufügen!
**Aktuell verwendet:**
- `DevExpress.Pdf.Core` v25.2.8
**Bei Bedarf verfügbar:**
- `DevExpress.Office.Core` (Word, Excel)
- `DevExpress.Document.Processor` (erweiterte Dokumenten-Verarbeitung)
- `DevExpress.Blazor` (falls UI später benötigt wird)
- Alle weiteren DevExpress Produkte
---
### 2. **Aktueller Projektstand**
#### ? Abgeschlossen (Completed)
**Phase 1: Foundation**
- ? Solution Structure (4 Projekte + Tests)
- ? Dependencies (Clean Architecture Rules)
- ? NuGet Packages installiert
- ? Folder Structure erstellt
- ? Configuration (appsettings.json, Options Pattern)
- ? Serilog Setup
- ? Program.cs Setup
**Phase 2: Domain Layer (Minimal)**
- ? **4 Domain Exceptions:**
- `DomainException.cs` (Basis)
- `DomainValidationException.cs` (Value Object Validierung)
- `NotFoundException.cs` (Resource nicht gefunden)
- `PdfProcessingException.cs` (PDF-spezifische Fehler)
- ? **2 Enums:**
- `DocumentOperationType` (Validate, ExtractAttachments, Concatenate, ApplyStamp, EmbedCertificate)
- `ProcessingStatus` (Pending, Processing, Success, Failed)
- ? **3 Value Objects:**
- `Base64String` (typsicher, selbst-validierend, mit Factory Methods)
- `TenantId` (normalisiert, validiert)
- `PdfMetadata` (PageCount, FileSizeBytes, PdfVersion, HasAttachments, etc.)
**Phase 3: Infrastructure Layer**
- ? **IPdfProcessor Interface** erstellt
- `Task<PdfMetadata> ValidateAsync(byte[] pdfBytes)`
- Mit XML Comments dokumentiert
---
#### ?? In Arbeit (In Progress)
**Phase 3: Infrastructure Layer**
- **NEXT:** Step 3.2 - `DevExpressPdfProcessor` implementieren (mit TDD!)
- Ordner `Services/PdfProcessing/` existiert bereits
- **Aber:** Noch leer - muss implementiert werden
---
#### ?? Wichtige Hinweise
**1. Application Layer - ProcessDocument vs ValidatePdf**
- **Problem:**
- Ordner: `Features/Documents/ProcessDocument/`
- Dateien: `ProcessDocumentCommand.cs`, `ProcessDocumentHandler.cs`, `ProcessDocumentValidator.cs`
- **Alle leer!**
- **Roadmap sagt:**
- Wir sollten mit `ValidatePdf` Feature starten (nicht ProcessDocument)
- **Action Required:**
- Entweder ProcessDocument-Dateien löschen
- Oder umbenennen zu ValidatePdf
- Oder erst später nutzen (wenn wir ein generisches ProcessDocument Command brauchen)
**2. Tests Layer**
- **Problem:** Nur `UnitTest1.cs` (Dummy-Test)
- **Action Required:**
- Ordnerstruktur erstellen:
```
Tests/
??? Unit/
? ??? Application/
? ??? Infrastructure/
? ??? Domain/
??? Integration/
??? API/
```
- `UnitTest1.cs` löschen
**3. Infrastructure Services**
- **Problem:** Ordner existieren, aber leer
- `Services/PdfProcessing/` ? DevExpressPdfProcessor.cs fehlt
- `Services/FileStorage/` ? leer
- `Services/DocumentValidation/` ? leer
- **Action Required:**
- Step 3.2 durchführen: DevExpressPdfProcessor implementieren
---
## ?? Nächste Schritte (Roadmap)
### Schritt 1: DevExpressPdfProcessor implementieren (Phase 3, Step 3.2)
**TDD-Flow:**
1. **Test schreiben** (Red)
- `Tests/Unit/Infrastructure/Services/PdfProcessing/DevExpressPdfProcessorTests.cs`
- Test: `ValidateAsync_ValidPdf_ReturnsMetadata()`
2. **Code schreiben** (Green)
- `Infrastructure/Services/PdfProcessing/DevExpressPdfProcessor.cs`
- `IPdfProcessor` Interface implementieren
- DevExpress PDF API nutzen
3. **Test grün machen**
4. **Refactoring** (falls nötig)
---
### Schritt 2: Application Layer aufräumen
**Option A: ProcessDocument löschen**
```powershell
Remove-Item "DocumentOperator.Application\Features\Documents\ProcessDocument" -Recurse
```
**Option B: Zu ValidatePdf umbenennen**
```powershell
Rename-Item "ProcessDocument" "ValidatePdf"
# Dann Dateien umbenennen + Namespaces anpassen
```
**Option C: Behalten und später nutzen**
- Erst ValidatePdf neu erstellen
- ProcessDocument später für generisches Command nutzen
---
### Schritt 3: MediatR Setup (Phase 4, Step 4.1)
**Erstellen:**
1. `Application/DependencyInjection.cs`
- MediatR registrieren
- FluentValidation registrieren
- ValidationBehavior registrieren
2. `Application/Common/Behaviors/ValidationBehavior.cs`
- Pipeline Behavior für FluentValidation
---
### Schritt 4: ValidatePdf Feature (Phase 4, Step 4.2)
**Erstellen:**
1. `Application/Features/Documents/ValidatePdf/ValidatePdfQuery.cs`
2. `Application/Features/Documents/ValidatePdf/ValidatePdfHandler.cs`
3. `Application/Features/Documents/ValidatePdf/ValidatePdfValidator.cs`
**Mit TDD:**
- `Tests/Unit/Application/Features/ValidatePdf/ValidatePdfHandlerTests.cs`
---
## ?? Empfehlung
**Nächster Sprint:**
1. ? ROADMAP.md ist aktuell
2. **Jetzt:** DevExpressPdfProcessor implementieren (mit TDD)
3. **Dann:** Application Layer aufräumen (ProcessDocument ? ValidatePdf)
4. **Dann:** MediatR Setup + ValidationBehavior
5. **Dann:** ValidatePdf Feature komplett durchziehen
**Vorteil dieses Ansatzes:**
- Wir sehen **echten** Code (DevExpress Integration)
- Wir wissen welche Exceptions geworfen werden
- Application Layer kann darauf aufbauen
- Schneller Feedback-Loop
---
## ?? Build Status
? **Build erfolgreich!** (17.01.2025)
Alle Projekte kompilieren ohne Fehler.
---
## ?? Dokumentation
- ? **ROADMAP.md** vollständig aktualisiert
- ? **STATUS_UPDATE_17_01_2025.md** erstellt (diese Datei)
- ? DevExpress Universal License dokumentiert
- ? Aktueller Projektstand dokumentiert
- ? Nächste Schritte klar definiert
---
**Last Updated:** 17.01.2025
**Status:** Ready für Phase 3, Step 3.2 (DevExpressPdfProcessor)
