Description

The current git.py file is excessively large, making it difficult to maintain and extend. Additionally, the file lacks proper unit tests, which increases the risk of introducing bugs when making changes.

Goals

1. Improve Code Organization: Break down the git.py file into smaller, more manageable modules or classes based on functionality.
2. Increase Test Coverage: Write comprehensive unit tests to cover all existing functionality.
3. Maintain Functionality: Ensure the refactoring does not introduce regressions by validating behavior through existing integrations or writing new integration tests.

Tasks

1. Analyze the Current Codebase:

   • Identify key functionalities and dependencies in git.py.
   • Group related functionalities to determine potential modules or classes.

2. Refactor the Code:

   • Split the file into smaller, logical components.
   • Ensure clear separation of concerns.

3. Add Unit Tests:

   • Write tests for existing functionalities to capture current behavior.
   • Use mocking where necessary to isolate external dependencies (e.g., file system or shell commands).

4. Validate Refactoring:

   • Run existing integration tests (if available).
   • Add new integration tests if needed to cover end-to-end workflows.

5. Document Changes:

   • Update any relevant documentation to reflect the new structure.
   • Provide guidelines on how to use the refactored modules.

Acceptance Criteria

• The git.py file is split into multiple smaller files or classes with clear responsibilities.
• Comprehensive unit tests exist for all functionalities in the refactored files.
• No regressions in functionality, verified through testing.

Additional Notes

• Consider using a tool like pytest for testing.
• Utilize type hints and adhere to PEP 8 for better code readability.
