# Verification Note for bf-5ta8q

## 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):
  ```rust
  for pdf_path in &pdf_files {
      println!("  - {}", pdf_path.display());
  }
  ```
- In `test_forms_extraction()` (line 75):
  ```rust
  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
