Some ideas I got from Jeremias Rõßler's talk: https://t.co/xWtA58Q9q5

- Snapshot testing is like version-control but for the outputs rather than the inputs (source code).

- Asserts in traditional unit tests are like "block lists" specifying which changes aren't allowed. Instead, snapshot testing allows you to specify an "allow list" of acceptable differences (e.g. timestamps).
