bf-3qpih: Write passing test case for assert_exit_code

Summary

Verified that the passing test case for assert_exit_code already exists in the codebase at /home/coding/pdftract/crates/pdftract-core/src/extract.rs:3070-3099.

Test Details

Test Name: test_extraction_result_assert_exit_code_success

Location: crates/pdftract-core/src/extract.rs:3070-3099

Test Logic:

1. Creates an ExtractionResult with error_count = 0 (which corresponds to exit code 0)
2. Calls assert_exit_code(0)
3. Asserts that the result is Ok(()) using assert!(result.assert_exit_code(0).is_ok())

Test Code:

#[test]
fn test_extraction_result_assert_exit_code_success() {
    // Test that assert_exit_code returns Ok(()) when exit codes match
    let result = ExtractionResult {
        fingerprint: "test".to_string(),
        pages: vec![],
        metadata: ExtractionMetadata {
            page_count: 0,
            receipts_mode: ReceiptsMode::Off,
            span_count: 0,
            block_count: 0,
            cache_status: None,
            cache_age_seconds: None,
            error_count: 0,
            reading_order_algorithm: None,
            diagnostics: vec![],
            profile_name: None,
            profile_version: None,
            profile_fields: None,
        },
        signatures: vec![],
        form_fields: vec![],
        links: vec![],
        attachments: vec![],
        threads: vec![],
        javascript_actions: vec![],
    };

    // Should succeed - extraction with no errors should have exit code 0
    assert!(result.assert_exit_code(0).is_ok());
}

Verification

Ran the test to confirm it passes:

cargo nextest run -p pdftract-core test_extraction_result_assert_exit_code_success --no-capture

Result: ✓ PASS

running 1 test
test extract::tests::test_extraction_result_assert_exit_code_success ... ok

test result: ok. 1 passed; 0 failed; 0 ignored; 0 measured; 2902 filtered out; finished in 0.00s

Acceptance Criteria Status

• Test case exists for passing scenario
• Test creates ExtractionResult with exit code 0 (via error_count = 0)
• Test calls assert_exit_code(0) and expects Ok(())
• Test passes when run
• Test follows existing test patterns in the codebase

Additional Context

The test follows the standard pattern for assertion method tests in the codebase:

• Uses #[test] attribute
• Includes descriptive comment explaining what is being tested
• Creates test fixtures inline with struct literal syntax
• Uses assert!(...) macro for simple boolean assertions
• Follows naming convention: test_<module>_<method>_<scenario>

Related tests that also exist:

• test_extraction_result_assert_exit_code_mismatch - tests failure case
• test_extraction_result_assert_exit_code_with_errors - tests exit code 1 for extractions with errors

Implementation Method

The assert_exit_code method implementation is at /home/coding/pdftract/crates/pdftract-core/src/extract.rs:2719-2736. It computes the exit code based on error_count (0 for success, 1 for any errors) and returns Ok(()) when the actual exit code matches the expected value.

Conclusion

All acceptance criteria are met. The passing test case for assert_exit_code is already implemented and functional.
