[Feature Request] Add Unit Tests

[Sploder12]

Is your feature request related to a problem? Please describe.

Unit Testing would provide a more structured way to verify any changes still function as intended. It would assist in bug-fixing and ensuring incoming changes don't break unrelated systems.

Describe the solution you'd like

Unit tests like those taught in CSE 116 would be beneficial.

Describe alternatives you've considered

No Unit tests and sad code.

Do we know of any good Python testing libraries to get started with?

[emilkovacev]

Pytest is an excellent unit testing library!
