LGTM! It may be the case that eventually we'll want to abstract some of these repeated concepts (getting the dataset, populating the mock, etc.) into some common classes, but that's maybe a good TODO for later.

LGTM as well! And totally agree with @erip. I will look into creating a base class that can handle some of the repeated logic across tests. For the time being, I think it's fine to get all of the tests implemented before the branch cut next week!
