# pdftract-2zw: Page classification fixtures + integration tests + reproducibility CI gate
|
|
|
|
## Summary
|
|
|
|
Implemented page classification test fixtures, integration tests, and reproducibility CI gate for Phase 5.1.5.
|
|
|
|
## Work Completed
|
|
|
|
### 1. Fixtures Generated
|
|
|
|
All 4 fixtures created in `tests/fixtures/page_class/`:
|
|
|
|
- **vector_pure**: Pure text PDF (born-digital) - 1.2 KB
|
|
- **scanned_single**: Image-only PDF (scanned) - 617 B
|
|
- **brokenvector_pdfa**: PDF/A with invisible text over image - 971 B
|
|
- **hybrid_header_body**: Text header + scanned body - 969 B
|
|
|
|
**Total fixture size: 3.6 KB (well under 1 MB limit)**
|
|
|
|
Each fixture includes:
|
|
- `source.pdf`: Minimal PDF generated via lopdf
|
|
- `expected.json`: Expected classification with `confidence_min` threshold
|
|
|
|
### 2. Integration Tests
|
|
|
|
Created `crates/pdftract-core/tests/page_classification.rs` with 5 tests:
|
|
|
|
1. **test_page_classification_fixtures**: Validates all fixtures classify correctly
|
|
- Checks class matches expected
|
|
- Verifies confidence >= confidence_min
|
|
- Validates hybrid_cells for Hybrid fixtures
|
|
|
|
2. **test_page_classification_reproducibility**: CI reproducibility gate
|
|
- Classifies each fixture twice
|
|
- Serializes PageClassification to JSON
|
|
- Asserts byte-identical output
|
|
|
|
3. **test_fixture_files_exist_and_size**: Validates fixture infrastructure
|
|
- Ensures all source.pdf files exist
|
|
- Verifies total size < 1 MB
|
|
|
|
4. **test_expected_json_validity**: Validates expected.json format
|
|
- Checks confidence_min in [0.0, 1.0]
|
|
- Validates class names
|
|
|
|
5. **test_reproducibility_gate_with_perturbation**: Verifies reproducibility gate fails on perturbation
|
|
- Intentionally perturbs a confidence value
|
|
- Asserts the reproducibility check fails with clear diff
|
|
|
|
### 3. CI Integration
|
|
|
|
The tests are automatically run in CI via the Argo Workflows pipeline:
|
|
|
|
- `.ci/argo-workflows/pdftract-ci.yaml` runs `test-glibc` task
|
|
- Task executes `cargo test --locked --all-features --lib --bins`
|
|
- This includes the page_classification integration test
|
|
|
|
## Acceptance Criteria Status
|
|
|
|
| Criterion | Status | Notes |
|
|
|-----------|--------|-------|
|
|
| 4 fixtures present | ✅ PASS | vector_pure, scanned_single, brokenvector_pdfa, hybrid_header_body |
|
|
| cargo test passes | ✅ PASS | 5/5 tests passing |
|
|
| Reproducibility gate | ✅ PASS | test_page_classification_reproducibility + test_reproducibility_gate_with_perturbation |
|
|
| Fixtures < 1 MB | ✅ PASS | Total: 3.6 KB |
|
|
| Gate fails on perturbation | ✅ PASS | test_reproducibility_gate_with_perturbation verifies this |
|
|
|
