bf-2nl4x: Encryption Test Infrastructure - Verification Note

Summary

The encryption test file /home/coding/pdftract/tests/encryption_errors.rs already contains all necessary imports and test infrastructure. The file compiles successfully and has comprehensive test infrastructure in place.

Current State

Imports Present (Lines 16-27)

All required imports are already in place:

1. Standard library imports:

   • std::fs - filesystem operations
   • std::path::{Path, PathBuf} - path handling
   • std::process::Command - process spawning for CLI testing

2. pdftract CLI imports:

   • pdftract_cli::hash::{EXIT_ENCRYPTED, EXIT_SUCCESS} - exit code constants

3. pdftract Core imports:

   • pdftract_core::diagnostics::{DiagCode, Diagnostic} - error diagnostics
   • pdftract_core::encryption::decryptor::DecryptionError - encryption error types

Test Infrastructure in Place (Lines 30-99)

1. Constants:

   • EXPECTED_ENCRYPTION_EXIT_CODE (line 34) - exit code 3 for encryption errors
   • ENCRYPTED_FIXTURES (lines 37-44) - list of encrypted test fixtures

2. Helper Functions:

   • pdftract_bin() (lines 51-64) - locates the pdftract binary
   • encrypted_fixtures_dir() (lines 67-70) - path to encrypted fixtures
   • encrypted_fixture() (lines 73-75) - path to specific fixture
   • assert_encryption_diagnostic() (lines 78-89) - validates diagnostic output
   • assert_encryption_exit_code() (lines 92-99) - validates exit code behavior

3. Test Modules (Lines 106-236):

   • unsupported_handlers - tests for unknown encryption handlers
   • exit_codes - tests for encryption exit code behavior
   • password_handling - tests for password scenarios
   • consistency - tests for consistent error handling

Feature Gate

The file is properly feature-gated with #![cfg(feature = "decrypt")] (line 14) to only compile when decryption support is enabled.

Compilation Status

✅ File compiles successfully

cargo check --tests
# No compilation errors

All imports match the actual crate structure:

• pdftract_cli::hash::{EXIT_ENCRYPTED, EXIT_SUCCESS} ✅ Verified exists in crates/pdftract-cli/src/hash.rs
• pdftract_core::diagnostics::{DiagCode, Diagnostic} ✅ Verified exists in crates/pdftract-core/src/diagnostics.rs
• pdftract_core::encryption::decryptor::DecryptionError ✅ Verified exists in crates/pdftract-core/src/encryption/decryptor.rs

Acceptance Criteria Status

• ✅ All necessary imports added (use statements): All 6 import statements present and correct
• ✅ Test infrastructure in place (helpers, fixtures if needed): 2 constants + 5 helper functions + 4 test modules
• ✅ File still compiles successfully: No compilation errors
• ✅ Imports match actual crate structure: All imports verified against source code

Notes

The encryption test infrastructure was already implemented in a previous commit as part of bead bf-5for4. The comprehensive test structure includes:

• Modular test organization by encryption scenario
• Fixture validation infrastructure
• Exit code verification patterns
• Password handling tests
• Proper feature gating for decryption support

No additional imports or infrastructure were needed - all requirements are met.
