Task

Write failing test case for assert_exit_code

Summary

Added comprehensive test test_extraction_result_assert_exit_code_error_message that verifies assert_exit_code returns an error when the exit code does not match the expected value.

Implementation

File Modified

• crates/pdftract-core/src/extract.rs (lines 3169-3213)

Test Added

#[test]
fn test_extraction_result_assert_exit_code_error_message()

This test:

1. Creates an ExtractionResult with exit code 1 (error_count = 1)
2. Calls assert_exit_code(0) expecting a different value
3. Asserts the method returns an Err(...)
4. Verifies the error message contains useful information about the mismatch

Test Coverage

• Verifies that assert_exit_code(0) returns Err when actual exit code is 1
• Validates error.expected = 0
• Validates error.actual = 1
• Checks error.description contains "extraction result had"
• Checks error.description contains "error"
• Validates error message Display formatting contains "expected 0" and "got 1"

cargo test --package pdftract-core --lib test_extraction_result_assert_exit_code_error_message

Acceptance Criteria

PASS Criteria

✅ Test case exists for failing scenario ✅ Test creates ExtractionResult with exit code 1 (error_count = 1) ✅ Test calls assert_exit_code(0) and expects Err(...) ✅ Test verifies error message contains useful information ✅ Test passes when run (detecting the failure correctly)

WARN Criteria

None - all acceptance criteria met successfully

Git Commit

Commit: test(bf-5emrx): add assert_exit_code error message verification test

Verification Notes

The test successfully verifies that assert_exit_code properly returns an AssertionError with:

• Correct expected value (0)
• Correct actual value (1)
• Descriptive error message mentioning the extraction result had errors

The test integrates seamlessly with the existing test suite and provides comprehensive coverage for the failure scenario.
