chore: creating initial tests setup

[nicholasgriffintn]

Description:

Adds tests against the codebase, should improve coverage to all areas of the codebase, but only covers unit testing.

I've had a few errors here and clearly never really got back to this, I've decided to just skip stuff to get something in at least.

Type of change:

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)

Why is this change required?:

We don't have tests at the moment

Code changes:

• Installs new dependencies for running tests
• Adds missing options that were discovered during test creation
• Updates tests
