HFS Utilities Test Suite

Comprehensive testing framework for Apple Silicon HFS utilities.

Quick Start

# Generate test data (HFS images and sample files)
./generate_test_data.sh

# Run all tests
./run_tests.sh

# Run specific test categories
./run_tests.sh basic        # Basic functionality tests
./run_tests.sh integration  # Integration workflow tests  
./run_tests.sh errors       # Error handling tests

# Simple integration demonstration
./simple_integration_test.sh

Test Structure

1. Test Data Generator (generate_test_data.sh)

Creates various HFS and HFS+ images and sample files for testing:

• Small images (1.44MB): Basic testing with simple file structure (HFS and HFS+)
• Medium images (10MB): More complex directory hierarchies (HFS and HFS+)
• Large images (50MB): Stress testing with many files (HFS and HFS+)
• Empty images: Testing empty volume operations (HFS and HFS+)
• Corrupted image: Error handling tests

2. Main Test Runner (run_tests.sh)

Comprehensive test harness with multiple test categories:

Basic Functionality Tests

• Utility existence checks
• Help/version output
• Mount/unmount operations
• Directory listing and navigation
• File operations (copy, delete, rename)
• Directory operations (create, remove)
• Volume information display

Integration Workflow Tests

• Backup/Restore: Complete backup and restoration workflow
• Archive Creation: Organizing files by type
• Volume Migration: Moving data between volumes
• File Management: Complex directory structures
• Data Recovery: Simulated recovery scenarios

Error Handling Tests

• Operations without mounted volumes
• Non-existent file/directory access
• Invalid operations (e.g., deleting directories with hdel)
• Edge cases (special characters, empty files, deep paths)

HFS+ Specific Tests

• HFS+ volume formatting with hformat -t hfs+ and mkfs.hfs+
• Filesystem type detection (HFS vs HFS+)
• Program name detection (mkfs.hfs, mkfs.hfs+, fsck.hfs+)
• HFS+ volume information and validation
• Mixed HFS/HFS+ operations and compatibility

3. Simple Integration Test (simple_integration_test.sh)

A straightforward demonstration that:

1. Creates and formats an HFS volume
2. Creates directory structure
3. Copies files to/from the volume
4. Tests navigation and file operations
5. Verifies all utilities work together

Test Options

./run_tests.sh [OPTIONS] [TEST_PATTERN]

Options:
  -v, --verbose     Enable verbose output
  -q, --quick       Skip stress tests
  -k, --keep        Keep test files for inspection
  -h, --help        Show help message

Test patterns:
  all              Run all tests (default)
  basic            Basic functionality only
  integration      Integration workflows only
  errors           Error handling only
  hfsplus          HFS+ specific tests only

Test Results

The test suite validates:

• ✅ All utilities compile and run on Apple Silicon
• ✅ Basic HFS operations (mount, copy, delete, rename)
• ✅ HFS+ volume creation and formatting
• ✅ Filesystem type detection and program name recognition
• ✅ Directory navigation and management
• ✅ Inter-utility workflows and data pipelines
• ✅ Error handling and edge cases
• ✅ Volume information and management
• ✅ Mixed HFS/HFS+ environment compatibility

Known Issues

1. MacBinary Detection: Binary files may trigger MacBinary format detection
2. Path Navigation: hcd changes affect relative paths in subsequent commands
3. Test Isolation: Some tests may leave mounted volumes on failure

Future Enhancements

• Performance benchmarking
• Stress testing with large file counts
• Concurrent operation testing
• Extended attribute preservation tests
• Cross-volume operation tests

Contributing

When adding new tests:

1. Add test data generation to generate_test_data.sh
2. Implement test function in run_tests.sh
3. Update appropriate test category in the case statement
4. Document any new test patterns in this README

Requirements

• Bash 3.2+
• Standard Unix utilities (dd, grep, etc.)
• Compiled HFS utilities in parent directory
