Coverage appears to be blocked for tests wrapped in a transaction

[Stuwert]

When I wrap tests in the runInTransaction function, jest coverage stops tracking coverage for functions and lines.

running the same tests both times.

Hi @Stuwert, apologies for the delay on getting back to you here. Could you maybe send me what fetchAcademicAndEmployerPartnerRules.ts looks like? I'd like to get an idea of why that may not work, it's likely that it's because we throw an exception in this framework to trigger the rollback. But I'll need so see the code to be sure, then I can write unit tests on my side to replicate the issue!

I'm also experiencing this issue. All the DB related calls are excluded from the coverage:
