Code Development and Testing

[thomasthaddeus]

• Complete the implementation of all functions and classes, ensuring they meet their design specifications.
• Write unit tests for each module (main.py, pip_batch_update.py, get_pip_cmds.py, log_utils.py, etc.) to ensure functionality works as expected.
• Perform integration testing to ensure all parts of the system work together seamlessly.
• Add exception handling across the application to manage errors gracefully.
