# Verification Note for bf-3h10m

|
|
## Task: Implement PDF fixture discovery for forms tests
|
|
|
|
## Implementation Status: COMPLETE
|
|
|
|
The PDF fixture discovery functionality was already implemented in `tests/forms_integration.rs`.
|
|
|
|
## Implementation Details
|
|
|
|
### Location
|
|
`/home/coding/pdftract/tests/forms_integration.rs`
|
|
|
|
### Function: `discover_pdf_fixtures`
|
|
|
|
**Lines: 20-37**
|
|
|
|
```rust
|
|
pub fn discover_pdf_fixtures<P: AsRef<Path>>(fixtures_path: P) -> Vec<PathBuf> {
|
|
let mut pdf_files = Vec::new();
|
|
|
|
let walker = WalkDir::new(fixtures_path)
|
|
.follow_links(false)
|
|
.into_iter()
|
|
.filter_map(|e| e.ok())
|
|
.filter(|e| {
|
|
e.file_type().is_file()
|
|
&& e.path().extension().map(|ext| ext == "pdf").unwrap_or(false)
|
|
})
|
|
.map(|e| e.path().to_path_buf());
|
|
|
|
pdf_files.extend(walker);
|
|
pdf_files.sort();
|
|
|
|
pdf_files
|
|
}
|
|
```
|
|
|
|
**Features:**
|
|
- Uses `walkdir` crate to recursively iterate through the fixtures directory
|
|
- Filters for files with `.pdf` extension
|
|
- Returns sorted `Vec<PathBuf>` of discovered PDF files
|
|
- Handles non-existent directories gracefully (returns empty vec)
|
|
|
|
### Test: `test_discover_pdf_fixtures`
|
|
|
|
**Lines: 40-58**
|
|
|
|
```rust
|
|
#[test]
|
|
fn test_discover_pdf_fixtures() {
|
|
let fixtures_dir = "tests/fixtures/forms";
|
|
let pdf_files = discover_pdf_fixtures(fixtures_dir);
|
|
|
|
println!("\n=== Discovered PDF Fixtures ===");
|
|
if pdf_files.is_empty() {
|
|
println!("No PDF files found in {}", fixtures_dir);
|
|
} else {
|
|
for pdf_path in &pdf_files {
|
|
println!(" - {}", pdf_path.display());
|
|
}
|
|
println!("Total: {} PDF file(s)", pdf_files.len());
|
|
}
|
|
println!("==============================\n");
|
|
|
|
// Test that the function runs without errors
|
|
let _ = pdf_files;
|
|
}
|
|
```
|
|
|
|
**Features:**
|
|
- Prints discovered fixture names when run (with `--nocapture` flag)
|
|
- Handles empty result gracefully
|
|
- Does not assert on count (flexible for fixture addition/removal)
|
|
|
|
## Acceptance Criteria Verification
|
|
|
|
### PASS - Function discovers all .pdf files in tests/fixtures/forms/
|
|
The `discover_pdf_fixtures` function uses `walkdir` to recursively find all `.pdf` files in the given directory.
|
|
|
|
### PASS - Test prints discovered fixture names when run
|
|
Running `cargo test --test forms_integration test_discover_pdf_fixtures -- --nocapture` prints the fixture names.
|
|
|
|
### PASS - Handles non-existent directory gracefully (empty vec)
|
|
When the directory has no PDF files or doesn't exist, `walkdir` returns an empty iterator, resulting in an empty vec. The test handles this case by printing "No PDF files found".
|
|
|
|
### PASS - No compilation errors
|
|
Test compiled and ran successfully with zero compilation errors.
|
|

```
|
|
|
|
## Notes
|
|
|
|
- The implementation uses the `walkdir` crate which is already a dependency
|
|
- The function is public and can be reused by other test modules
|
|
- The test follows the project's pattern of fixture discovery used in other test modules
|
|
- The `tests/forms_integration.rs` file also includes a `test_forms_extraction` test that uses the discovery function to process all discovered fixtures
