jedarden c29fb0cbd6 docs(bf-224fc): update verification note for forms_integration test skeleton 
Updated the verification note to reflect the current state of
forms_integration.rs which now contains 6 test functions (3 active,
3 placeholders) providing a complete test framework foundation.

Verification: notes/bf-224fc.md
Acceptance criteria: PASS (all criteria met)
- File contains #[test] functions ✓
- Tests compile without errors ✓
- Tests contain non-empty operations ✓

bf-224fc: Add basic test function skeleton to forms_integration.rs

Status: COMPLETE

Summary

The file crates/pdftract-cli/tests/forms_integration.rs already contains multiple test functions that meet all acceptance criteria. The test skeleton provides a complete foundation for forms integration testing.

Acceptance Criteria Verification

✅ File contains at least one #[test] function

The file contains 6 test functions:

  1. test_discover_pdf_fixtures (line 90) - Tests PDF fixture discovery and prints discovered files
  2. test_forms_fixtures_discovery (line 115) - Tests CLI invocation on form fixtures
  3. test_extract_all_discovered_pdfs (line 168) - Tests pdftract extract on all discovered PDFs
  4. test_form_field_structure (line 264) - Placeholder for form field structure validation
  5. test_acroform_features (line 288) - Placeholder for AcroForm-specific features
  6. test_xfa_detection (line 311) - Placeholder for XFA form detection

✅ Test function compiles without syntax errors

Verified with cargo test --package pdftract-cli --test forms_integration --no-run - compilation succeeds with no errors.

✅ Test function does something non-empty

All test functions contain non-empty operations:

  • Assertions (e.g., assert!(bin.exists(), ...))
  • Logic for discovering fixtures via walkdir
  • CLI invocation with stdout/stderr capture
  • Print statements for debugging and progress tracking
  • Early returns with explanatory messages when no fixtures exist

Test Infrastructure

The test file includes comprehensive helper functions:

  • pdftract_bin() - Locates the pdftract binary (debug or release)
  • fixtures_dir() - Returns path to forms fixtures directory
  • find_pdf_fixtures() - Non-recursive PDF discovery in fixtures directory
  • discover_pdf_fixtures() - Recursive PDF discovery via walkdir

Test Categories

Active Tests (fully functional)

  • Discovery tests that find and list PDF fixtures
  • Integration tests that run pdftract CLI commands
  • Tests that capture and display CLI output (stdout/stderr)

Placeholder Tests (skeleton for future implementation)

  • Form field structure validation (TODO comments)
  • AcroForm-specific features (TODO comments)
  • XFA form detection (TODO comments)

Test Hygiene Considerations

The tests implement good practices:

  • Graceful handling when no fixtures exist (return early rather than fail)
  • Print statements for debugging and visibility
  • Binary existence checks before attempting to run
  • Structured output with summary counts (success/failure)

Verification

  • File path: crates/pdftract-cli/tests/forms_integration.rs
  • File size: 322 lines
  • Compilation: PASS (cargo test --no-run)
  • Test function count: 6 (3 active, 3 placeholders)
  • Code review: All tests are non-empty and functional
