## Test Structure & Strategy
|
||||
|
||||
**3-folder structure (CORRECT approach by previous developer):**
|
||||
|
||||
```
|
||||
DocumentOperator.Tests/
|
||||
├── Integration/
|
||||
│ └── API/
|
||||
│ ├── PdfValidationControllerTests.cs (13 tests)
|
||||
│ └── ExtractSwissQrCodeEndpointTests.cs (2 tests)
|
||||
├── TestData/
|
||||
│ └── Pdfs/ (EmbeddedResource PDFs)
|
||||
├── Unit/
|
||||
│ ├── Application/
|
||||
│ │ └── Features/
|
||||
│ │ ├── ValidatePdf/
|
||||
│ │ │ └── ValidatePdfHandlerTests.cs (2 tests)
|
||||
│ │ ├── ValidatePdfA/
|
||||
│ │ │ └── ValidatePdfAQueryHandlerTests.cs (4 tests)
|
||||
│ │ └── ExtractSwissQrCode/
|
||||
│ │ └── ExtractSwissQrCodeHandlerTests.cs (2 tests)
|
||||
│ └── Infrastructure/
|
||||
│ └── Services/
|
||||
│ └── PdfProcessing/
|
||||
│ └── DevExpressPdfProcessorTests.cs (7 tests)
|
||||
```
|
||||
|
||||
**✅ Why this structure is CORRECT:**
|
||||
|
||||
1. **Integration vs Unit separation:**
|
||||
- **Integration:** WebApplicationFactory → REAL API calls (HTTP, middleware, MediatR pipeline, DevExpress)
|
||||
- **Unit:** Mock-based ISOLATED tests (Handler only depends on mocked IPdfProcessor)
|
||||
|
||||
2. **TestData centralization:**
|
||||
- All 3 layers share same EmbeddedResource PDFs (no duplication)
|
||||
- Accessed via `Assembly.GetManifestResourceStream()`
|
||||
|
||||
3. **Vertical Slice compliance:**
|
||||
- `Unit/Application/Features/ValidatePdf/` → Each feature's tests co-located
|
||||
- Matches Application layer structure exactly
|
||||
|
||||
4. **Test Pyramid:**
|
||||
- **Unit tests (15):** Fast, isolated, many scenarios
|
||||
- **Integration tests (15):** Slower, full pipeline, critical paths only
|
||||
|
||||
**Test count:** 30 tests total (as of Feature 3 - PDF/A Validation)
|
||||
|
||||
**FluentValidation in tests:**
|
||||
- Base64 format validation happens in `ValidatePdfQueryValidator` and `ValidatePdfAQueryValidator`
|
||||
- Prevents `FormatException` from reaching handler (caught as 400 Bad Request, not 500)
|
||||
- Unit tests verify handler behavior with valid inputs only
|
||||
- Integration tests verify full validation pipeline (including FluentValidation)

# DocumentOperator API - Manual Testing Guide
|
||||
|
||||
This guide contains manual test scenarios for validating the DocumentOperator API endpoints using Swagger UI or tools like Postman.
|
||||
|
||||
---
|
||||
|
||||
## Prerequisites
|
||||
|
||||
1. **Start the API:**
|
||||
```powershell
|
||||
dotnet run --project DocumentOperator.API
|
||||
```
|
||||
Default URL: `https://localhost:5001` (check console output for actual port)
|
||||
|
||||
2. **Open Swagger UI:**
|
||||
Navigate to `https://localhost:<port>/swagger`
|
||||
|
||||
3. **Test PDFs:**
|
||||
- Use PDFs from `fake-pdf/` folder (form.pdf, multi-page.pdf, one-page.pdf, with-image.pdf)
|
||||
- Or use your own PDF files
|
||||

## Test Coverage Summary
|
||||
|
||||
| Feature | Endpoint | Test Cases |
|
||||
|---------|----------|------------|
|
||||
| Basic PDF Validation | `POST /api/pdf/validation/validate` | 6 |
|
||||
| PDF/A Validation | `POST /api/pdf/validation/validate-pdfa` | 5 |
|
||||
| Swiss QR Code | `POST /api/swissqrcode/extract` | 2 |
|

| Error Handling | All endpoints | 3 |
|

| **TOTAL** | | **16 Manual Test Cases** |
|
||||
|

|
||||
|
||||
## Notes
|
||||
|
||||
- All endpoints support **BOTH** `multipart/form-data` (file upload) AND `application/json` (Base64)
|
||||
- FluentValidation runs before handlers (400 errors indicate validation failures)
|
||||
- DevExpress evaluation warnings (DX1000/DX1001) are expected and can be ignored
|
||||
- Test PDFs in `fake-pdf/` folder are small samples; use real-world PDFs for comprehensive testing

## Quick PowerShell Helpers
|
||||
|
||||
**Convert PDF to Base64:**
|
||||
```powershell
|
||||
$bytes = [System.IO.File]::ReadAllBytes("path\to\file.pdf")
|
||||
$base64 = [Convert]::ToBase64String($bytes)
|
||||
$base64 | Set-Clipboard # Copies to clipboard
|
||||
```
|
||||
|
||||
**Create empty PDF for testing:**
|
||||
```powershell
|
||||
New-Item -Path "empty.pdf" -ItemType File -Force
|
||||
```
|
||||
|
||||
**Check if file is valid PDF:**
|
||||
```powershell
|
||||
$header = Get-Content -Path "file.pdf" -TotalCount 1 -Encoding Byte
|
||||
# Should start with: 0x25 0x50 0x44 0x46 (%PDF)
