Summary

This PR introduces unit tests for the pydumpling CLI, ensuring robust validation and functionality. Key highlights include:

• Validation Tests:

• Main Functionality Tests:

  • Tested main function for --print, --debug, and --rdebug actions, ensuring proper calls to respective handlers.

  • Mocked dependencies like os.path.exists and CLI-specific functions for isolated testing.

• Parser Tests:

  • Verified behavior for missing arguments, multiple conflicting actions, and invalid filenames.

  • Ensured --help displays the correct CLI usage information.

These tests improve coverage and reliability for the pydumpling CLI.
