Create comprehensive documentation of the cleaned tests/fixtures/ structure
following the three-bead cleanup effort (bf-1iefu, bf-xqib3, bf-2yhak).
Changes:
- Create: tests/fixtures/STRUCTURE.md with complete directory organization
- Directory structure with annotations
- Cleanup history and justification
- List of 10 KEEP generators (co-located with fixtures)
- List of 5 removed DELETE generators
- List of 2 relocated RELOCATE tools
- Maintenance guidelines
- Update: tools/README.md with cleanup summary section
- Three-bead coordination overview
- Final state statistics
- Links to related documentation
- Create: notes/bf-620xp.md verification note
Verification:
- ✅ No compiled artifacts remain
- ✅ No obsolete generators remain
- ✅ 10 KEEP generators remain (actively maintained, co-located with fixtures)
- ✅ All RELOCATE tools in tools/ with documentation
- ✅ Binary .bin files are legitimate test data (LZW compression, malformed fixtures)
Closes bf-620xp
Verified that the repository already contains PDF test fixtures with JavaScript actions:
- tests/fixtures/security/embedded-js.pdf (working, contains app.alert actions)
- tests/document_model/fixtures/js_in_openaction.pdf (parsing error)
Documented extraction results and fixture locations for reference.
No new fixture creation needed - existing fixtures serve the purpose.
- Analyze current test assertions in error_recovery_integration.rs
- Analyze current test assertions in stream_decoder_fixtures.rs
- Identify 5 major coverage gaps in truncated-flate recovery testing
- Document missing diagnostic emission in FlateDecoder
- Document lack of actual extraction in integration test
- Map out recommendations for new assertions at high/medium/low priority
Closes bf-303t6.
The file test_truncated_flate_recovery.rs does not exist.
Documented related test files and fixture patterns.
Identified that test_truncated_mid_stream() in error_recovery_integration.rs
is the closest existing test for truncated stream handling.
Acceptance criteria:
- Test file located: NOT FOUND (file does not exist)
- Related test structures: DOCUMENTED
- Existing test functions: LISTED
- Verify all encryption test attributes are properly configured
- Confirm #[test], #[cfg(feature = "decrypt")], and #[ignore] usage
- Validate test framework recognition and compilation success
- Document 18 passing tests with 1 ignored performance test
- Closes bf-53l6m
Add comprehensive test utility and error handling imports to encryption test files:
- Added std::error::Error and std::io for error handling
- Expanded pdftract_core::diagnostics imports to include Diagnostic, DiagnosticsCollector, and ObjRef
- Ensured both test_encryption_errors.rs and test_encryption_unsupported.rs have consistent imports
All imports verified against actual crate structure and compile successfully.
Closes bf-1h5og. Verification: notes/bf-1h5og.md.
