Acceptance Criteria

discordjs doesn't really provide a testing suite, meaning we can't really mock a real discord + bot environment.
We should stick to testing internally used utility functions/helpers. Basically any function that "works" outside of the discord context.

no, but maybe we can mock discordjs 🤔
