Thanks for adding all these unit tests, @justinkambic! I don't think I have push permission to your branches so I couldn't rebase & merge all the opened PRs myself. I assume the tests for this PR failed because the dependent commits aren't included yet?

Feel free to bulk-merge them 😎

Actually not sure why that happened, but it has passed numerous runs now, so I will go ahead and merge it.
