Set Up Python Testing Infrastructure

Summary

This PR establishes a comprehensive testing infrastructure for the SyzScope project, providing a ready-to-use environment for writing and running tests.

Changes Made

• Package Management: Migrated from requirements.txt to Poetry with complete pyproject.toml configuration
• Testing Framework: Added pytest with pytest-cov and pytest-mock as development dependencies
• Test Organization: Created structured testing directories:
  • tests/ - Main testing package
  • tests/unit/ - Unit tests directory
  • tests/integration/ - Integration tests directory
• Configuration: Comprehensive pytest configuration in pyproject.toml with:
  • 80% test coverage threshold
  • HTML and XML coverage reports
  • Custom test markers: unit, integration, slow
  • Proper test discovery patterns
• Shared Fixtures: Extensive conftest.py with reusable fixtures for:
  • Temporary directories and files
  • Mock VM instances and kernel objects
  • Mock crash cases and analysis components
  • Environment variable mocking
  • Sample binary and C files for testing
• Validation: Infrastructure validation tests to ensure setup works correctly
• Development Tools: Updated .gitignore with appropriate testing exclusions

Running Tests

To run tests after setting up the environment:

# Install dependencies
poetry install

# Run all tests
poetry run test
# or
poetry run tests

# Run with coverage
poetry run pytest --cov=syzscope

# Run specific test types
poetry run pytest -m unit        # Unit tests only
poetry run pytest -m integration # Integration tests only
poetry run pytest -m slow        # Slow tests only

Coverage Reporting

Coverage reports are generated in multiple formats:

• Terminal output with missing lines
• HTML report in htmlcov/ directory
• XML report as coverage.xml

Dependencies

The infrastructure includes testing-specific dependencies:

• pytest ^7.0 - Main testing framework
• pytest-cov ^4.0 - Coverage reporting
• pytest-mock ^3.10 - Mocking utilities

Notes

• All production dependencies from requirements.txt have been migrated to Poetry format
• The Poetry configuration allows for both exact version pinning and flexible constraints where appropriate
• The testing infrastructure is framework-agnostic and can be extended for any testing needs
• Infrastructure validation tests ensure the setup works correctly across different environments
