Always
awaitfor the initial render setup inCompositeunit testsWhy?
Looking at the code, it looks like the correct thing to do is to
awaitfor that setup function to execute.This change should improve test reliability (I think I've seen some flakiness around composite tests).
How?
By
awaiting every call to therenderAndValidateutility in unit testsTesting Instructions
Unit tests should continue passing (and if there was any flakiness, that should improve)
