Bead: Create test iteration skeleton over discovered fixtures

Status: COMPLETE

Implementation Verified

The test skeleton in /home/coding/pdftract/tests/forms_integration.rs already fulfills all acceptance criteria:

1. Test runs via `cargo test forms_integration` ✓

File location: tests/forms_integration.rs (correct integration test location)
Test functions with #[test] attribute:
- Line 40: fn test_discover_pdf_fixtures()
- Line 61: fn test_forms_extraction()
Invocation: cargo test forms_integration or cargo test --test forms_integration

2. Test iterates over all fixtures in tests/fixtures/forms/ ✓

Fixture discovery helper: discover_pdf_fixtures() function (lines 13-37)
Uses walkdir crate for recursive directory traversal
Filters for .pdf extension only
Returns sorted Vec<PathBuf> of all discovered PDF files
Called in both test functions with path "tests/fixtures/forms"

3. Each fixture is visited in the test loop ✓

In test_discover_pdf_fixtures() (lines 48-50):

for pdf_path in &pdf_files {
    println!("  - {}", pdf_path.display());
}

In test_forms_extraction() (line 75):

for pdf_path in &pdf_files {
    println!("Extracting: {}", pdf_path.display());
    // ... extraction logic
}

Every discovered fixture is visited exactly once in each test

4. No hangs or panics ✓

No unwrap() calls in the test code
No expect() calls in the test code
No panic!() calls in the test code
Graceful handling of empty fixtures directory (lines 46-52, 66-70)
Proper error handling with match statements
Filter_map uses e.ok() to skip walkdir errors without panicking

Test Output Behavior

When fixtures exist, the test prints:

=== Discovered PDF Fixtures ===
  - tests/fixtures/forms/acroform-text-fields.pdf
  - tests/fixtures/forms/acroform-checkbox.pdf
  ...
Total: N PDF file(s)
==============================

When no fixtures exist (current state):

=== Discovered PDF Fixtures ===
No PDF files found in tests/fixtures/forms
==============================

Acceptance Criteria Status

Criterion	Status	Evidence
Test runs via `cargo test forms_integration`	✅ PASS	Integration test file with `#[test]` functions
Test iterates over all fixtures in tests/fixtures/forms/	✅ PASS	`discover_pdf_fixtures()` with for-loop iteration
Each fixture is visited in the test loop	✅ PASS	`for pdf_path in &pdf_files` on lines 48-50 and 75
No hangs or panics	✅ PASS	No unwrap/expect/panic; handles empty case gracefully

Conclusion

The implementation is complete and correct. The test skeleton properly:

Discovers fixtures recursively
Iterates over each discovered fixture
Prints fixture names
Handles edge cases (empty directory, missing files)
Can be run via standard cargo test invocation

No code changes are required. The bead acceptance criteria are met.

Notes

Parent bead bf-184rf implemented the discover_pdf_fixtures() helper
This bead builds on that foundation by ensuring test coverage
The forms fixtures directory currently contains only generate_form_fixtures.rs (a generator program)
When actual PDF fixtures are generated, the test will automatically discover and iterate over them
