Create unit tests for all modules

[TB-1993]

Goal: All control modules should have a unit test to prove their functionality

Currently, only a few of the control modules have unit tests that full test their functionality. This ticket is more of a placeholder for the backlog to show that all modules will require unit tests to prove their functionality.

Acceptance Criteria:

• A unit test will be in place for module exists
• Each test will test all exposed methods from each module and ensure they work correctly
