Overview
Write unit tests for node behaviors.

Objectives:

• Validate the functionality of individual node methods.
• Ensure nodes behave correctly under various conditions.
• Facilitate regression testing for future code changes.

Checklist:

• Develop test cases for each method in the Node class.
• Use a testing framework suitable for C++.
• Automate the testing process and integrate it into the build pipeline.

Additional Notes:

• Aim for high code coverage to catch potential issues early.
