Rewrite tests for refactored functions

[brandynlucca]

Once the codebase has been refactored, existing tests will need to be rewritten or new tests added for newly introduced functions. This Issue will track the completion of tests for the various modules. There may be new modules added or removed entirely, so this list will be iteratively tracked. This will be closed once tests for the refactoring have been put together.
