Refactors for Coverage Scoping

[garrettmflynn]

This PR gets coverage near 50% by adding additional unit tests. Some utilities have also been reorganized for better scoping.

Wanted to open this early so that the process is transparent.

Alright as long as the tests pass, this should be good to go.

Just to emphasize what has been done, here's a representation of the folder hierarchies within the coverage report:

All files
└── electron
    └── frontend
        └── core
            └── components
                └── table
                    └── cells
                        └── renderers
            └── progress
            └── validation
        └── utils
└── schemas

@CodyCBakerPhD Sorry about that. Looks like only Linux failing now.
