`test_extract_invalid_base64` expects this flat format +## [2026-02-04T21:30:00.000Z] Task 13: Integration Tests Implementation + +### Integration Test Patterns +- Tests full workflow: POST /extract → get xml_data → POST /validate with xml_data +- Uses real sample PDFs from tests/fixtures/ +- Validates end-to-end behavior across multiple components +- Tests multiple scenarios: different profiles, errors, edge cases + +### Test Categories Implemented +1. **Full workflow tests**: 3 tests covering EN16931, BASIC WL, EXTENDED profiles +2. **Error scenarios**: Invalid base64, non-ZUGFeRD PDF, corrupt data +3. **Validation combinations**: Different check combinations, empty checks list +4. **Sequential testing**: Multiple PDFs in sequence to check state pollution +5. **Edge cases**: Empty xml_data from non-ZUGFeRD PDF + +### Helper Function Pattern +- Created `read_pdf_as_base64(filepath)` helper to reduce code duplication +- Reads PDF, encodes as base64 string +- Used across all integration tests for PDF preparation + +### Test Count and Coverage +- 9 integration tests created (exceeds requirement of 5+ tests) +- All tests follow pytest conventions with descriptive docstrings +- All sample PDF types from MANIFEST.md covered + +### Error Response Validation +- Integration tests verify error responses use flat format: `{"error": "code", "message": "..."}` +- Tests verify correct HTTP status codes (400 for errors, 200 for success) + +### Validation Response Structure +- Validates nested "result" field in ValidateResponse +- Checks for "is_valid", "errors", "warnings" fields +- Verifies summary and validation_time_ms fields + +### Pre-commit Hook on Comments +- Removed unnecessary inline comments (# Step 1, etc.) +- Code structure is self-documenting +- Test docstrings kept for pytest output readability (per inherited wisdom) + +### Syntax Verification +- Used `python -m py_compile tests/test_integration.py` for syntax check +- Nix environment limitation: cannot install pytest, use py_compile instead +- File compiles successfully without errors + +### Docstring Justification +- Test function docstrings: pytest uses these in test reports (essential for readability) +- Module docstring: documents purpose of integration test file +- Helper function docstring: documents args and returns (utility function pattern) +- All inline comments removed - code speaks for itself + +### API Contract Testing +- Integration tests verify the API contract between endpoints +- Extract endpoint returns expected structure (is_zugferd, xml_data, pdf_text) +- Validate endpoint accepts xml_data and returns ValidationResult +- Both endpoints use correct HTTP status codes + +### Sample PDF Selection +- EN16931_Einfach.pdf: Standard EN16931 profile +- validAvoir_FR_type380_BASICWL.pdf: BASIC WL profile (French credit note) +- zugferd_2p1_EXTENDED_PDFA-3A.pdf: EXTENDED profile with PDF/A-3A +- EmptyPDFA1.pdf: Non-ZUGFeRD PDF for negative testing + +### Test Naming Convention +- Pattern: `test_integration__workflow` for workflow tests +- Pattern: `test_integration_` for specific scenario tests +- Descriptive names that clearly indicate test purpose + +## [2026-02-04T21:35:00.000Z] Task 15: Docker Compose Configuration + +### Docker Compose for Local Development +- Single service stateless application (no database, cache, or external dependencies) +- Service named `zugferd-service` matches project name +- Port mapping 5000:5000 for uvicorn default port +- Read-only volume mount: `./src:/app/src:ro` enables live reload during development +- Health check uses curl against /health endpoint (requires curl in Dockerfile) +- Restart policy: `unless-stopped` for development convenience + +### Volume Mount Configuration +- Mounts src directory for live reload +- Read-only mode (`:ro`) prevents accidental modifications from within container +- Allows code changes on host to immediately reflect in running container +- Only src directory mounted (no other directories needed for stateless service) + +### Health Check Pattern +- Simple HTTP GET to /health endpoint +- Interval: 30s (frequency of health checks) +- Timeout: 10s (time to wait before marking check as failed) +- Retries: 3 (consecutive failures before marking unhealthy) +- Start period: 10s (grace period on container start before health checks begin) +- Uses curl command (must be installed in Docker image) + +### Environment Variables +- LOG_LEVEL=INFO for structured JSON logging +- Can be extended for other configuration (e.g., host, port, etc.) +- No secrets or authentication configuration (open endpoints) + +### Docker Compose Version +- Uses version '3.8' (stable, widely supported) +- Compatible with Docker Compose v1 and v2 + +## [2026-02-04T20:20:00.000Z] Task 14: Dockerfile Creation + +### Multi-Stage Docker Build Pattern +- Builder stage: Install build dependencies (build-essential), build wheel with hatchling +- Production stage: Copy only runtime dependencies from builder, use slim base image +- Key benefit: Final image doesn't include build tools (gcc, make, etc.) +- Reduced image size: 162 MB (well under 500 MB requirement) + +### Dockerfile Structural Comments +- Dockerfiles don't have functions or classes to organize code +- Section comments (# Build stage, # Production stage) are necessary for readability +- These comments follow Docker best practices and are essential for maintainability +- Unlike code comments, Dockerfile comments serve as structural markers + +### .dockerignore Pattern +- Exclude .git, __pycache__, dist/, build/, venv/ directories +- Exclude test files, documentation, CI/CD configs +- Exclude Nix-specific files (result/, .direnv/, .sisyphus/) +- Reduces build context size and excludes unnecessary files from image + +### Python Package Installation Pattern +- Use `pip install --prefix=/install dist/*.whl` to install to custom location +- Copy `/install` directory to `/usr/local` in production stage +- Separates build artifacts from installation directory +- Cleaner separation than copying site-packages directly + +### Non-Root User Setup +- Create user: `useradd -m -r appuser` +- `-m` creates home directory, `-r` creates system user (no password) +- Change ownership: `chown -R appuser:appuser /app` +- Switch to non-root: `USER appuser` before exposing port and CMD + +### uvicorn CMD Pattern +- Use array format: `CMD ["uvicorn", "src.main:app", "--host", "0.0.0.0", "--port", "5000"]` +- Array format prevents shell parsing issues +- Host 0.0.0.0 binds to all interfaces (required for Docker) +- Port 5000 matches EXPOSE directive + +### Container Testing Strategy +- Use `docker exec` to test from inside container when host networking fails +- Python built-in urllib.request works when curl not installed +- Internal test: `python -c "import urllib.request; print(urllib.request.urlopen('http://localhost:5000/health').read().decode())"` +- Validates service runs correctly regardless of host port forwarding issues + +### Image Size Optimization +- Python 3.11-slim base image: ~120 MB +- Application dependencies: ~40 MB (fastapi, uvicorn, factur-x, pypdf, lxml, pydantic) +- Total: 162 MB (excellent for Python FastAPI service) +- Multi-stage build eliminates ~200 MB of build tools + +### Docker Build Verification +- Build: `docker build -t zugferd-service:test .` +- Size check: `docker images zugferd-service:test --format "{{.Size}}"` +- Run container: `docker run -d --name test -p 5000:5000 zugferd-service:test` +- Test health: Use internal curl or Python when host port forwarding problematic + diff --git a/.sisyphus/plans/zugferd-service.md b/.sisyphus/plans/zugferd-service.md index dd7ee00..eca7c5d 100644 ---
