Very nice structure, this looks easy to understand and easy to add more test scenarios 👍

Is there a code-climate plugin for test coverage for this, similar to what we have in ndb-core? Would be neat to see it as github PR checks (and track it in code-climate) instead of the multiple bot comments 😊

A ton of e2e test scenarios are still missing of course. Shall we create a separate issue for these?
(creating calculations, getting actual data calculated by sqs and all the webhook parts are critically to get tested ASAP)
